Cisco CCNA Candidate FAQ
CCNA FAQ
Q. What exams do I have to take to get my CCNA?
A. The CCNA (Cisco Certified Network Associate) certification offers two paths. You can take the one-exam path by taking the 640-801 CCNA Composite exam. If you want to break it up into two parts, you can take the Introduction To Cisco Networking Technologies (INTRO 640-821) and the Interconnecting Cisco Networking Devcies (ICND 640-811) exams.
Q. Chris, which path do you recommend?
A. I generally recommend the two-exam path, particularly for those CCNA candidates that haven't taken a Cisco exam before. The Intro exam offers you a little more time and allows you to become comfortable with the Cisco exam engine, particularly the simulator questions. Let's face it, the CCNA single exam covers a lot of material, from basic networking to OSPF to router on a stick. Most candidates are better off breaking this huge amount of material into two distinct parts.
Don't get me wrong, I've had plenty of students and customers pass the CCNA composite. It can be done!
Q. Do I have to recertify my CCNA, or is it mine forever after I pass?
A. One way Cisco protects the value of its certifications is to enforce strict recertification policies. When you earn your CCNA, you must recertify within three years.
Q. How do I recertify my CCNA?
A. There is a lot of confusion out there on this question. The latest information from Cisco is that you recertify your CCNA by doing any of the following three things:
1. Pass the current CCNA Composite or ICND exam.
2. Pass any 642-level professional level exam or any Cisco Qualified Specialist exam, not including Sales Specialist exams.
3. Pass any CCIE written exam.
Q. How do I register for the CCNA exam?
A. You can take the CCNA exam at any Prometric or VUE testing center. To find a Prometric testing center near you and register online, visit www.2test.com . For a VUE site, register at www.vue.com .In the 70-290 exam resources, MCDBA Managing and Maintaining a Microsoft Windows Server 2003 Environment, you will cover every field and category in MCDBA helping to ready you for your successful Microsoft Certification.
In the 70-620 exam resources, TS:Configuring Windows Vista Client, you will cover every field and category in Microsoft Windows Vista, Configuring helping to ready you for your successful Microsoft Certification.
In the 350-001 exam resources, CCIE-ROUTING AND SWITCHING QUALIFICATION (Written exam), you will cover every field and category in CCIE helping to ready you for your successful Cisco Certification.
Q. Can you give me a braindump for the exam?
A. Boy, do you have the wrong guy!

Don't Quit Reading - Use Reading Glasses!
Surgery may correct distance vision, but it creates the need for reading glasses. Reading glasses look like normal glasses, but they actually give you good distance vision and good reading vision. For detail activities such as prolonged reading, have a pair of reading glasses made that provide balanced near vision. Almost a third of the American population needs reading glasses, but engineers designing web sites are typically under 40 with perfect vision. This often leaves them with perfect reading vision, without glasses, in old age, despite having lost accommodation through presbyopia. People who do not need glasses for distance vision may only need half glasses or reading glasses. In the past, traditional eye exams for near vision have resulted in glasses suited only for reading printed material, not for viewing computer screens. People with natural 20/20 distance vision will likely need reading glasses when presbyopia develops. Even if you achieve excellent vision through surgery, reading glasses are usually necessary beyond 45 years of age. If you have Lasik to correct your distance vision, you'll still need reading glasses around age 45. Of course, one can use two different pairs of glasses, each with single vision lenses - one pair just for reading, and another for looking into the distance. eyeglasses online
Distance
This is what reading glasses are about; they let you focus in on fine detail at a close distance. Baby boomers who have LASIK may end up trading in their old distance glasses for reading glasses. For those who need distance of midfield glasses, bifocals can often be the answer to providing for both distance and reading needs. Other customers may wish to consider the option of owning two pairs of glasses; one pair for distance and another for reading. And with half-eye reading glasses, you can look down through the lenses for reading and over the lenses to see in the distance. They will turn your standard distance glasses into reading glasses or your reading glasses into super magnifying lenses.
Wearing Your Glasses
Contacts have given me back some youth, but when I have them in I have to wear reading glasses. Speaking of glasses, I wear reading glasses when using a computer. I would recommend this group to anyone looking for unique and/or quality reading glasses - Roseanne-Arizona. And despite Dorothy Parker's famous quip, women do look attractive who wear eyeglasses for reading. This means to wear the compact reading glasses down a bit on your nose. If you already wear regular glasses or reading glasses, you may be tempted to dismiss the need for computer glasses. Even non eyeglasses wearers can wear them over their sunglasses when working or reading outside. You wouldn't wear reading glasses for driving, or at least I hope you wouldn't. I think it was because I kept reading books with dimmed lights that made me started to wear glasses. There is no need to wear reading glasses underneath your safety glasses ever again. reading eyeglasses
Computer
These glasses give these people the ability to have proper eye protection, and allow easy reading of plans, instructions and computer screens. Some may need to use reading glasses for close work such as reading, using a computer, or sewing. For activities like reading or working on a computer, patients who've had cataracts removed commonly require reading glasses. Caution should be used concerning buying ready-made magnifying or reading glasses off the rack in stores to use as computer glasses.
Case
By using a reading glasses case you will prevent accidents that could ruin them. Mini reading glasses almost always come with a case designed specifically for this type of reading glasses. Plastic or metal reading glasses can be used with either a hard or soft case. Most likely a soft case will come with plastic reading glasses. The soft fabric protects the lens while the soft case is basically just storage for the reading glasses. Often such readers come with a hard case that is designed to store a specific style of reading glasses. tiffany & co
Lens
That is when you start reaching for reading glasses, because you need the extra power that your own lens can't provide anymore. Off-the-rack reading glasses have the same lens power in each lens. Flip-up reading glasses - these are like the flip-up sunglasses, except they provide a magnifying lens. Even contact lens users often use reading glasses. Tiffany Bracelets
Prescription
If you're experiencing those problems, visit your eye doctor for a reading glasses prescription. While pinholes are not as cheap as off-the-rack reading glasses, they are considerabley cheaper than individual prescription glasses. Purchasing reading glasses made up to your prescription is the perfect way to solve this problem. If they say you need a prescription, tell them that reading glasses can be bought in drugstores without a prescription. Over-the-counter reading glasses are inexpensive eyeglasses that can be purchased in variety, drug, and discount stores without a prescription.

Embrace The Beauty Of Life With Your Eyes Without Glasses Now!
More to your surprise, let me tell you that the first ever lasik sort surgery was performed by a Columbian lasik surgeon, Jose Barraquer who essentially experimented with the elimination of more than half of the cornea in patients whose vision had been consulted for a number of reasons. Once the cornea was removed, it was frozen and reshaped to get a better vision. After getting redesigned, the cornea was sewn back into its place in the patient's eye. This became the basic beginning of counteractive eye surgery. In the 1960s, in Russia, technology was further urbanized, which allowed the reshaping of the cornea to occur while it remained in the patient's eye only. This corrective process was performed using a scalpel. The development went on and reached today's famous lasik surgery and lasik vision institutetitanium eyeglasses.
Well there are many features of surgery but the most significant aspect of any surgery is the lasik surgeon. Just after the low cost, never prefer an inexperienced and layman surgeon who can later give nothing but troubles. So, it's better to keep the cost aside and zero on the best surgeon while not negotiating your vision. Always check the credentials, professional ability, experience, etc. before starting with the procedure. The lasik surgeon should be a good doctor who first off, listens to every doubt and query of patients with patience and chooses the right procedure for the eligible candidate.
Well thanks to Internet that has eased you to set a good surgeon and look for his competences to a great level. Never believe in low cost advertisements. While searching for your lasik surgeon, always analyze what are included in the whole package. If you see the metal eyeglassesprice tag of $299 and you rush for that, remember, it might be just the surface amount for the procedure. Later you may be bombarded with huge bills leading your blood pressure go high. So, first make certain about the quoted cost and its credible benefits.
To more of your interest, our eyes are as unique and as individual as our fingerprints, more fascinatingly, each eye can be different from the other, requiring in total different treatment. A skilled and trained lasik doctor will first modify your treatment to give you the best eyesight you can ever have. No matter what the context in life, customizing will always take more time and proficiency, but yield a better consequence for sure.
Wavefront-guided lasik makes a really superior choice from this perspective, as it so precisely maps your individual eye characteristics, and guides the treating laser accordingly. To have this competence and excellence, certain equipments may cost the lasik surgeon more and so the price tends to rise. But go for it without a second though as it will be worth spent at the end. There has been always a high demand for the lasik surgery. No doubt, the technology is more luxurious but ascribed to its great results; it is always adopted without fears. With time and advancement, the cost of pre-op testing and screening is sharply rising because of number of factors.
There are some lasik surgeons, who include the follow-up visits in the plastic eyeglassesinitial cost including any treatment therein. It is also suggested to discuss with your lasik surgeon the available augmentation surgeries that may be required after the initial surgery. For a few cases as an exception, further treatment for the rest of the life may be mandatory. All these issues should be discussed with the doctor. In addition to this, you must be aware of the fact that in order to give you a quality LASIK surgery New York, the surgical facility and proficiency must cover many expenses like:
Lease tiffany&co silveror buy of the laser, microkeratome, and other essential equipment, and their maintenance

Products for low vision
Low vision devices include eyeglasses, but there are many more low vision products available today that can assist patients in living with macular degeneration symptoms. While laser surgery can be used to treat the “wet” variety of age-related macular degeneration, or AMD, there is no known cure for the “dry” form of this leading cause of blindness. However,low vision devices can help such a victim in making the most of what eyesight remains.
Age related macular degeneration (AMD) affects the central part of the retina, and therefore one’s ability to determine fine details such as print, faces, and images. Essentially, one develops a “hole” in one’s vision; if the subject is looking at an object that appears smaller than this “hole,” the object cannot be seen clearly.Therefore, the purpose of low vision devices is to increase the apparent size of these objects.
Because we use our eyes in different ways in different situations, there is no one solution for addressing macular degeneration symptoms. One patient may require several different low vision products. Bifocal reading glasses are one of the best known and most common low vision devices, Tiffany jewelybut may not be appropriate for all macular degeneration symptoms.Cheap Tiffany Bracelets
Bioptic glasses for low vision, also known as bioptic telescopes, are low vision devices that actually consist of miniature telescopes mounted atop a pair of regular glasses. Such low vision devices can be adjusted for a wide range of activities that require both distance and near vision. While bioptic glasses for low vision work in the same way (you tilt your head forward slightly), they differ from bifocal reading glasses in that the telescopic lens is not integrated into the primary lens itself.
Other low vision products for age related macular degeneration include such products as the portable digital magnifier, which resembles “virtual reality” goggles and is used in conjunction with a special pair of glasses. One of the most interesting low vision products on the market today consists of a miniature TV camera that actually rests on the surface of whatever the patient is reading, magnifies it, and sends that image electronically, projecting an image on the inner surfaces of eyeglass lenses! Such a system allows the patient’s head to remain in an upright position; no longer is it necessary to tilt one’s head.tiffany's
Of course, such high-tech vision aids are quite expensive at the present. However, if the history of other technologies such as the PC and the DVD is any indicator, the cost of such low vision devices should come down substantially over the next few years.

Lasik Vision Correction: Choosing To See
For many people in the world, lasik vision correction is the best thing that can happen to them. If you are one of the many people that fumble with glasses each morning or have to pretend that it is easy to pop your contact lenses in, then you may be a perfect candidate for this procedure. While the surgery isn’t all that simple, it is effective for many patients. In order to know if it is something that is right for you, then you’ll need to contact your eye doctor. Here is what you’ll want to think about before you decide on lasik vision correction surgery.
How Does It Work
What will happen is the eye surgeon will give you anesthetics as well as numb the eye area. Then, he will hold open your eye with a special device that doesn’t allow you to blink. Using a laser that triggers an area over 400 times per second, he will re sculpt the eye’s cornea thereby correcting your vision.
Sounds really easy right? There is much more to it of course. And, yes, you will be awake during the procedure. But, you will likely go home within a few hours, be told to sleep the rest of the day and then you’ll be good to go from there, in most cases.
What Can It Fix?
Laser vision correction surgery can often repair the vision of individuals who have nearsighted or farsightedness. Many other conditions can be improved as well. Mostly, those who have healthy, disease free eyes that have a problem with the shape of the actual cornea can be helped.
How Do I Get Help?
When you are considering a surgery such as this, you need to look for experienced doctors. The best way to do that is not to flip through the telephone directory but to spend some time really researching the doctors out there. Here’s what you are looking for:
· Experience and references of satisfied customers of the eye doctor.
· Customer service skills offered by the staff as well as by the doctor himself. Do you feel comfortable with him, in other words?
· Trust is vital. You need someone that you can trust to do a good job, not someone who is too busy about pushing you through your appointment.
· Look for your local area doctor’s association for more help in finding the doctor in your area that is qualified. Often, you can find them by using the web to look for Colorado eye specialists through a search for example.
There are many things that this surgery can do for you. It can help to improve your vision overall as well as to provide you with color vision correction, distance sight that is clear, and it will help you to be confident in yourself again. Lasik vision correction may be the perfect solution to your poor vision problems.

Low Vision Aids Help Make Your Life More Active
Low vision can be caused by any number of reasons. Genetics can play a part, such as the low vision that is common in albinism. Accidents can have an impact on a person's vision, as can age. As people age, they are at a greater risk for developing macular degeneration. Macular degeneration causes a loss of central vision, which is crucial for such activities as reading, watching television or seeing a computer screen clearly. There are low vision aids that can help make these activities a part of your life again. They can include bifocal reading glasses, magnifiers, and telescopic glasses. Many vision problems can be resolved by using a variety of suitable low vision products.
Bifocal Reading Glasses
Bifocals allow the wearer to see both near and far distances depending on which part of the eyeglass lens he or she looks through. They typically have a smaller reading lens placed in the bottom part of a regular sized lens used for distance sight. The wearer can shift focus by moving the head up or down to look through the appropriate part of the lens for the task at hand. There is also a type of bifocal that has no line where the division of lenses meet; they are called progressive or graduated lenses. These low vision reading aids come with lenses that offer minimum magnification at the top of the lens increasing to maximum magnification at the bottom of the lens.

Magnifiers
These low vision aids help to increase the size of the image seen by the person with low vision. This is an important aspect of dealing with low vision effectively, because when the central vision is damaged, the larger you can make the image the more visible the image will be despite the central vision loss. Magnifiers can be hand held or designed as a lens to be inserted into the glass frame, and are useful for close vision activities such as reading or playing cards.
Telescopic Glasses
Low vision aids that utilize tiny telescopes on the glass lenses are useful when the wearer wishes to participate in activities that require distance vision, although they can be adjusted for mid-range and near vision as well. The telescopes are attached to the top of the glass lens, and you use them in a similar fashion as you would bifocals, by shifting your head to change the vision range. If your vision needs change over time, bioptic glasses can be readjusted easily to meet your ocular needs. Rimless frame
You will want to consult with a low vision specialist who can help guide you in selecting and using the best variety of low vision aids that will assist you in performing the daily activities that you love.

Jewelry chain all in the Dinh family
Between 1975 and 1979, Tien Dinh and Mui Luong tried unsuccessfully six times to escape from Vietnam with their six children.
Many escaping families split up hoping to improve the chances that at least some of them would make it, said son Hanh Dinh. “But my parents said, ‘Whoever God gave us is family. If we die, we all die. If we live, we all live.’ ”
The seventh attempt in 1979 was successful for all eight family members. They arrived in Indonesia and then in Garden Grove.
Hanh Dinh tells the story to explain why his family makes all their personal and business decisions as a unit.
Hanh and his brother Hai are listed as owners of NQ. Jewellers that recently opened in Fountain Valley. But the whole family really owns this newest store, Hanh emphasizes, just as the whole family owns four other jewelry stores in the Asian Garden Mall in Westminster.
They succeed or fail as a family.
It is an unusual achievement. Only about a third of family-owned small businesses survive into the second generation. Different goals, ambitions and management styles have disrupted more than one Thanksgiving dinner for families that jointly own businesses.
After the Dinhs moved to Garden Grove, family members old enough to work got jobs sewing clothes in the Southern California garment industry, says Hanh, who was nine when the family escaped Vietnam.
“But my mom’s passion, even when she was young in Vietnam, was to have a jewelry store,” he said.
Family members pooled their assets and in 1988, the Dinhs opened their first jewelry shop, Ngoc Quang, in the Asian Garden Mall, one of the largest Vietnamese retail centers in the United States with about 400 stores, more than 150 of them selling jewelry from tiny stalls as well as enclosed stores. Despite that competition, Ngoc Quang became known as a store with quality merchandise, Hanh says.
The children went to the Gemological Institute of America, at that time in Santa Monica, to learn diamond grading and jewelry manufacturing.
As the first shop prospered, the family opened another shop with the same name in the same mall, which built on the reputation the Ngoc Quang brand already had. Tien Dinh and Mui Luong became known in the Vietnamese community as Mr. and Mrs. Ngoc Quang, Hanh said laughing.
Each business was still part of the family enterprise. Everyone pitched in money and labor to build each new enterprise.
“My dad always saw this as a country of opportunity,” Hanh said, “All these years my parents work for the kids, and they wanted to keep us all close.”
Two years ago the family started thinking about the need to reach out to the non-Vietnamese community.
That idea built on the 2002 success of the Euro-Asian Furnishings store that daughter Van Dinh and her husband Peter Phan opened in Fountain Valley for mainstream shoppers.
“The new generation is coming and (the grandchildren) will be American,” Hanh says. “We try to keep them in the family business, but if we’re not approaching the mainstream, there won’t be opportunities for all of them.”
A discount store, Factory 2 U, was closing next to Phan’s furniture store, and the Dinhs thought the location would good for a different, grander jewelry store that Ngoc Quang has built in Westminster.
However, the entire family had to agree on every decision.
“Every meeting we discussed ideas. Some (family members) rejects, some agreed. We continued until everyone agreed on each idea,” Hanh says. “My parents wanted something that flowed and didn’t block the (customer’s) view (of the entire store) so we discussed how to make that work.”
Hanh shrugs at that process as though every family runs its enterprises on unanimous votes.
The resulting store is 8,000 square feet, built in glass and lined in cherry wood. The cases carry such brands as Verragio, ESQ Swiss and Michael B. Flat-screen televisions mounted around the store show videos of various jewelry products.
In the back, jewelry designers and repair technicians work in a windowed room so customers can watch. Security is heavy but not heavy handed.
The family decided on a less Vietnamese name, NQ. Jewellers – deliberately misspelling the word to get attention – in the hope of attracting a broad customer base.
In the weeks leading up to the opening, dozens of people cleaned glass, stocked cases and hung crystals from the dozens of orchid plants around the store.

Truth Behind Eye Care Myths
We have been hearing some myths about eye care from our childhood and we sometimes are guided by those. So it is very necessary for all of us to know the actual truth behind these myths to take better care of not only our eyes but also that of our children. Some of the famous doctors uncovered the truth.
Eating carrots improves my eyesight.
This is a very popular and as well as an ancient myth of eye care. This myth influences us in such a range that we often eat carrot without cooking it and think it as the best eye care. Now it is the time to look up the truth. Dr. David Kercheval, OD, of Kercheval Eye Care says that this story stems from the days when folks didn’t get enough vitamin A in their diet and needed carrots for an extra boost.
“It is a rare deficiency in the U.S., so eating a lot of carrots will do nothing but turn your skin yellow,” Kercheval said.
According to Dr. Amy Walden, OD, an optometrist for Family Eye Care at LensCrafters, lot of beta-carotene in carrots is indeed very good for eyes, but it hardly improve eye sight.
UV protected glass is not necessary for me
“You definitely need that filter,” Walden said. “Most of our glasses and sunglasses have the UV protection — and some have UVB protection to filter out rays from the sun that can cause cataracts.”
It is highly recommended even if you are a contact lens user.
Can I use my disposable contact lenses for much longer than the recommended duration.
You cannot do so. According to Walden, lens wearers who overextend their lens’ recommended lifetime are prone to infections, corneal ulcers and swelling in the cornea, and ultimately they starve the eye of oxygen. Eventually, the lenses break down and stretch to the point they no longer fit the eye properly.
“Hygiene and replacing of the lenses offer the best opportunity for eyes to do well and see well,” McCormick said.
Only those who need glasses require to go for their eye check up regularly.
Sometime we think that as we do not have glasses our eye is perfect and their is no need of regular eye checkup. But these check up not only can indicate whether you need glasses or contacts, they also screen for retinal detachment, glaucoma, cataracts and other potentially harmful conditions.
Walden said many other illnesses show up in the eyes first, including high blood pressure, diabetes and high cholesterol. Even when a person’s vision isn’t impaired, these conditions can be detected in the retina, she noted.

Jewelry Making Findings Can Make Or Break A Jewelry Project
Jewelry making findings are the essential pieces which make the bead and wire a piece of jewelry. Jewelry making findings are simply the components of any piece of jewelry; the findings consist of clasps, head pins, ear clutches, jump rings and any other manufactured or hand made component. Separate headings of 'Findings" are listed in all jewelry making supply catalogs or websites. A craft or hobby store will have the header listed in their jewelry supply area. Jewelry making findings is a major revenue business all by itself.
Ear Wire
Ear wires are the jewelry making findings that are used to connect a beautiful earring body to the wearer's ear. Ear wires are essential when making earrings; they are generally silver, gold and copper. There is also silver and gold plated, as well as, gold filled.

Small zip lock bags are also considered tiffany jewellery making findings. Plastic zip lock bags or small fabric pouches are items which must be considered when selling your jewelry or keeping it safe. Oils and everyday pollution will harm your jewelry making findings and, therefore, must be kept in containers before and after they are made into jewelry.
Sizes of these bags depend upon your necklace, bracelet and earring projects. But jewelry making findings must always include small bags of some capacity.
Clasps
Toggle clasps, jump rings, lobster clasps, S clasps and magnetic clasps are all examples of jewelry making findings. These are all necessary components to make any necklace or bracelet work. Your beads or crystals, wire or chains and clasps is all that it takes to make a spectacular necklace or bracelet.

The Magic And History Of Aquamarine Jewelry
While all gems found on this world are special in their own way, the aquamarine is very unique. This gem that symbolizes the month of March has always had magic and mystical elements surronduing it. March, for many of us, is a month that is said to come in like a lion and go out like a lamb; in others words, this month is a very speacial time for those who experience all four seasons as March brings them from winter into spring. Aquamarine jewelry is very special in its own right and has a wonderful history.
aquamarine jewelry
Aquamarine jewelry is very special jewelry. The aquamarine stands for the month of March. Birthstones were chosen long ago by ancient civilizations to represent the months of the year, and all of the stones that were chosen were preciios ones.
Over time, the gems have changed to make what is now known as the official list of birthstones. The list kept changing so much that the National Association of Jewelers created a standard list for the stones. The United States, as well as Australia and other counties now follow this standard.
Aquamarine jewelry is made from one of the most beautiful gems, the aquamarine which means water of the sea in Latin. This is a proper name for such a stone, as it has almost a see-through appearance while maintaining its sparkling blue color. Aquamarine jewelry is actually made from beryl and when it is found in blue, it is usally what we all know as aquamarine. Beryl also can be found in yellow, white and pink.
Aquamarine jewelry is crafted from stones that are found in mines all over the world. One of the biggest mines is in Russia; however they produce the yellow beryl. Clear to white beryl can be found in Brazil and the United States has many aquamarine mines. Blue beryl can be found at the base of the Colorado Mountains. It is most likely for that reason that the aquamarine is the official stone of the state of Colorado. If beryl is found in a color other than blue, jewelry crafters can heat the stone, causing it to turn to the shiny blue color that we are used to seeing in aquamarine jewelry. Generally, the darker the blue, the more expensive the aquamarine jewelry.
If you think that aquamarine comes in a standard size, think again. In the year 1910 in Brazil, an aquamarine stone was found that weights more than one hundred and ten kilograms. While we may not all be able to have a piece of aquamarine jewelry that boasts such a collosal gem, we can still all hold onto a piece of the magic. The most interesting history involving aquamarine is the fact that people used to believe that aquamarine is what made up the tail end of mermaids. For that reason, sailors would wear aquamarine jewelry to protect themselves while they ventured across the seas.
In the Middle Ages, it was believed that aquamarine jewelry would cure someone if they were poisoned. As aquamarine jewelry does not actually cure poison, it is wondered why this belief would last very long! It may not have those special powers, but it certainly can keep the magic alive; aquamarine jewelry is the popular jewelry to be given on a couple’s nineteenth wedding aniversary.
aquamarine jewelry
Aquamarine jewelry is very special jewelry. The aquamarine stands for the month of March. Birthstones were chosen long ago by ancient civilizations to represent the months of the year, and all of the stones that were chosen were preciios ones.
Over time, the gems have changed to make what is now known as the official list of birthstones. The list kept changing so much that the National Association of Jewelers created a standard list for the stones. The United States, as well as Australia and other counties now follow this standard.
Aquamarine jewelry is made from one of the most beautiful gems, the aquamarine which means water of the sea in Latin. This is a proper name for such a stone, as it has almost a see-through appearance while maintaining its sparkling blue color. Aquamarine jewelry is actually made from beryl and when it is found in blue, it is usally what we all know as aquamarine. Beryl also can be found in yellow, white and pink.
Aquamarine jewelry is crafted from stones that are found in mines all over the world. One of the biggest mines is in Russia; however they produce the yellow beryl. Clear to white beryl can be found in Brazil and the United States has many aquamarine mines. Blue beryl can be found at the base of the Colorado Mountains. It is most likely for that reason that the aquamarine is the official stone of the state of Colorado. If beryl is found in a color other than blue, jewelry crafters can heat the stone, causing it to turn to the shiny blue color that we are used to seeing in aquamarine jewelry. Generally, the darker the blue, the more expensive the aquamarine jewelry.

Eye conditions Optometrists commonly treat
Myopia
Myopia, or nearsightedness, is an eye condition that inhibits clear vision from far away. About 13,253* people will visit Cheyenne Optometrists for vision obstructed by myopia. By 2020, it is estimated that there will be 2.5 billion people in the world, and approximately 20,073* in Cheyenne, Wyoming with nearsightedness. Myopia can be corrected with glasses, contact lenses, or Refractive surgery.
Hyperopia
Hyperopia, also known as farsightedness, is the opposite of myopia, patients have difficulty seeing up close, but clear vision far away. There are approximately 11,662* cases of people having hyperopia in Cheyenne, Wyoming. Over half the people with farsightedness are above the age 65. Hyperopia, like myopia, is most frequently treated with corrective lenses or refractive surgery.
Presbyopia
Presbyopia is the natural loss of your eyes' ability to focus on nearby objects. This is an age related condition, usually developing after age 40. 1 in 11, about 5,831* people in Cheyenne, Wyoming now have their vision compromised by presbyopia. Difficulty reading is the most common early warning sign used to detect presbyopia. Text seems to have less contrast and must be well lit, and held further away to see clearly. There are about 590 million presbyopes in the world, which equals about 4,737* in Cheyenne, Wyoming. By 2020, it's estimated to rise to 8,029* in Cheyenne, WY and 1 billion in the World.
Astigmatism
Astigmatism causes blurry vision due to an irregular shaped cornea. The normal shape of the cornea is round, but astigmatism occurs when it's shaped more like an oval or a football. With an irregular shaped cornea, light enters the eye and focuses at 2 points instead of one. Over 45 Million Americans have astigmatism. About 7,993* patients in Cheyenne, WY see Optometrists for problems with astigmatism. The most common treatment is with special prescription Toric lenses, that bend light along two axis. Another treatment option is refractive surgery which corrects the shape of the cornea.
Glaucoma
Glaucoma occurs when the normal fluid pressure inside the eyes slowly rises. This damage results in gradual visual changes and eventually loss of vision. In the US, more than 2 million glaucoma related visits are made to Optometrist's office each year. Another 1.1 million cases go undetected. In Cheyenne, Wyoming that would equal about 392* detected and 196* undetected. Most patients with glaucoma require only medication to control the eye pressure. With early treatment, you can often protect your eyes against serious vision loss.
Amblyopia
Amblyopia is commonly known as lazy eye, a condition affecting approximately 3% of children under 15, about 436* in Cheyenne, Wyoming. This condition develops at an early age and is commonly caused by either one eye having stronger vision than the other, strabismus (cross-eye or wall-eye), or blockage of an eye due to trauma or lid droop. Treatment for amblyopia is done by strengthening the weaker eye with medicated drops or an eye patch. Children age 7-17 are likely to benefit most from the treatment, with a much lower success rate in adults.
Strabismus
Strabismus, also known as cross-eyed or wall-eyed, is a disorder that causes one eye to be misaligned with the other when focusing. Due to a lack of coordination, the eyes look in different directions and do not focus at the same time on a single point. Approximately 177* visits are made to optometrists in Cheyenne, Wyoming concerning strabismus. Treatments for strabismus include glasses, medication, eye exercises, or surgery if non surgical means are unsuccessful. When left untreated, 30-50% of children with strabismus develop secondary vision loss in the form of lazy eye.

Reading Glasses and Fashion
Many people find themselves in need of single-vision reading glasses. It's not a sin. In fact, reading glasses can be fashionable, colorful, and fun to coordinate with your wardrobe. There are full size, half-eyes, bifocals which are "plano" or no added Rx on the top so you can actually walk in them without getting dizzy, sun readers, and wallet readers which work great for restaurant menu reading.
Reading glasses can be custom-made for each individual through an optical dispenser, or they can be purchased "ready-made" at retail shops or online at stores. Ready-made readers became popular in the 1990s: three times more pairs were purchased during that decade than ever before, at an estimated rate of 30 million pairs per year. They are less expensive than custom eyewear, allowing you to own several pairs for a reasonably small amount of money.

Binocular Vision
Having 20/20 eyesight doesn't guarantee that you have perfect vision. Reading an eye chart is a specific, static visual task. But most daily activities require our eyes to perform more demanding, dynamic functions.
Clear, comfortable vision depends on how well our eyes work together as a team. This teaming of the eyes is called binocularity, or binocular vision. If each eye has 20/20 eyesight but the two eyes are not properly aligned to work together efficiently as a team, blurred vision, eyestrain and headaches can occur.
Computer use and other near vision tasks require our eyes to work together while pointing slightly inward. This inward direction of the line of sight of each eye is called convergence.
Reading and computer work also require our eyes to move quickly and accurately from point to point on a page or screen. And the closer objects are, the more focusing effort our eyes have to perform.
Many visual tasks also require that we change the focus and position of our eyes quickly and repeatedly (taking notes during a classroom lecture, for example). This changing of the focus point of our eyes is called Accommodation.
People who have perfect 20/20 eyesight can have binocular vision problems that can cause headaches, eyestrain, and blurred vision. Binocular vision problems may also cause reading problems among school-aged children.
If you or one of your children are experiencing frequent headaches and eyestrain, see your eye doctor to determine if you have a binocular vision or accommodative problem. Many binocularity and focusing problems can be successfully treated with vision therapy or special prescription eyewear.

Eye Doctors Disciplined For Wrong Treatment
The Florida Board of Medicine has decided to take action against two Polk doctors for wrong treatment. Both the doctors were charged with mistakes in treating patients. The Florida Board has decided to accept the disciplinary settlement made by Dr. Alan Lingenfelter, a Winter Haven anesthesiologist. The accused doctor is fined with $ 5,000. Other than that, he will deliver a one-hour lecture on wrong-site surgeries, as well as doing 50 hours of community service.
Dr. Lingenfelter, was accused of applying applied anesthesia beside the wrong eye, while preparing a patient for the cataract surgery in 2005 at Sebring. He later on documented his error medical records and told the eye surgeon what had happened.
Another complaint accuses a retired Lake Wales doctor for wrong treatment. The board however accepted the accused Doctor, Dr William Hardman's offer to relinquish his Florida medical license to resolve a 2003 medical complaint. The charge against him of damaging bladder and intestine of a woman during a tubal litigation he performed. The next day, she complains of severe abdominal pain. Hardman gave her antibiotic only to harm her health. The complaint said this is a known complication of tubal ligation and that Hardman hadn't kept sufficient medical records to justify the treatment he provided.

Building Solid Relationships
Throughout our twenty-six years of producing SuperCamp learning and life skills academic summer camp programs for teens and youth, we have also endeavored to give parents some of the tools they might need to support the continued personal growth of their children after their return from our summer camp.
We have found the following to be worthwhile elements in building rapport with children:
• Know what they like, how they think, and how they feel about what’s happening in their lives.
• Imagine what they say to themselves, about themselves.
• Know what keeps them from getting what they truly want. If you don’t know, ask.
• Speak the truth to them in a way they can hear it, clearly and gently.
• Have fun with them.
• Treat them as equals.
Many of the beliefs that we teach and practice at SuperCamp are worth sharing with SuperCamp families. We strongly believe that:
• Respect and caring – for ourselves and for others – is vitally important.
• Every person is gifted and capable of learning.
• There are no failures, only learning experiences through which we gain greater self-understanding.
• Positive support, a nurturing environment, and good communication are essential – for learning and for life.
Parents who make an effort to build their relationships with their children will also build their feelings of acceptance and trust – which will in turn build their self confidence. Self-confidence is a vital ingredient in the happiness and academic success of our children.
Learn More at SuperCamp
At SuperCamp, our exceptional staff go in-depth with campers from age 9 to 18 on how to build strong relationships with friends and family and on many other life and learning skills that help build grades, confidence and motivation. Our Youth Forum is seven days long and is for students going into grades 4-5 in the fall. Junior Forum and Senior Forum are 10 days long. Junior Forum is for incoming 6-8 graders and Senior Forum is for incoming 9-12 graders. We even have a college boot camp, Quantum U, an 8-day programs for incoming college freshmen.
SuperCamp is held at eight beautiful colleges across the U.S. throughout the summer. Quantum U takes place at Colorado College in Colorado Springs. More information on our programs is available at www.supercamp.com and www.quantum-u.com.
We also offer a unique 3-day Parent Weekend at which parents of kids in SuperCamp gain an insight into what their children are learning in their programs. In the process, parents tell us they learn a lot about themselves, as well.

High Index Eyeglass Lenses
As anybody who has had to wear thick lenses can tell you, it can make you a little self-conscious and you would do anything for something a little thinner. Lenses are made from a variety of materials. Many of these materials are designed to be thinner than a conventional lens. This means that they have a higher Index of refraction. Index of Refraction refers to the lenses ability to bend light. The prescription of a lens is determined by two main factors; the lens?s index of refraction and lens curvature. The higher the index the less curvature that is needed thus the lens can be processed thinner. The lower the index the more curvature is needed for the desired prescription thus making it thicker.
Often you may hear the Optician or doctor referring to these lenses by numbers such as such as 1.60, 1.66, and 1.70. These numbers represent the refractive power of the lens. The higher the number the thinner the lens. There are several other benefits to a high index lens. Lenses with a higher index often have a greater tensile strength than other conventional materials. This tensile strength is around 15,000 psi! This makes them suitable for drill mount glasses.
But because a lens is thinner and tougher does not mean that it is without flaws. The higher the index the more reflection that occurs off of the lens surface. The higher the index the more resistance is given to light. This resistance increases the amount of light that is bounces off. For instance a conventional plastic lens with an index of 1.498 will cause 8% of the light to reflect off of the surfaces creating 92% transmission. A lens with the index of 1.70 will cause 13.6% of the light to be reflected creating only 86.4% transmission. The application of an Anti-reflective coating can greatly increase light transmission.

A Window of Light Into the Heart of Darkness
Dr Jeremy Joseph volunteered to perform cataract surgery on patients in Zimbabwe in 1995, and participated in his first expedition for SEE International (Surgical Eye Expeditions). This London-based ophthalmologist knew to expect hundreds of patients prematurely blinded by cataracts; their condition compounded by poor facilities and lack of medication.
What he had not anticipated was the powerful impact this experience would have on his own life. "My work with SEE International is challenging and inspiring; very much a two-way process," says Dr Joseph. "I have gained just as much from my experience as I have given back. Many of the cases are not ordinary cataracts. Patients are often young with traumatic cataracts, or they are old with complex cataracts. I've had to learn to operate in less than ideal circumstances, where the water or electricity supply or both can stop at any time. But I've had the pleasure of working with some of the world's most dedicated ophthalmologists, and the experience has been one of personal growth and confidence for me".
This seems to be an ongoing learning process. At the end of a follow-up Eye Camp in Namibia, where Dr Joseph and his colleagues operated on more than 125 patients, they walked into a local hall where the patients had gathered to say goodbye. "Every patient, who had previously been brought in blind, and who could now see, came forward and in turn clasped each surgeon's hand in thanks. The room spilled over with emotion," says Dr Joseph.
Cataract-induced blindness in this part of the world robs the individual of the ability to work and earn a living, and the social and economic consequences of blindness, are staggering. Dr Joseph expands, "Our work isn't just about giving people back their sight; we are helping them get their lives back."
Since that first expedition, Dr Joseph has participated in nine more. He is one of hundreds of ophthalmologists from around the globe, that have teamed up with SEE International to devote their time and energy to fight cataract induced blindness, and other eye diseases in the developing world.
According to the World Health Organisation (WHO), cataracts account for about half of the world's preventable blindness and bilateral cataracts (cataracts in both eyes) currently blind at least 20 million people. Harry Brown, a Californian ophthalmologist, launched SEE International in the early 1970s with a group of trained ophthalmic surgeons, nurses, and technicians from around the world.
Dr Brown's aim was to transform languishing lives into productive ones. Now that this dream has reached fruition, thousands of blind people in more than 40 countries including the Philippines, Mexico, Peru, Thailand, Kenya, Ecuador, and Malawi are successfully treated. More than 600 volunteer ophthalmologists offer their services each year. Despite the help dispensed to many patients; there are still some who are not receiving treatment due to the fact that SEE International can only operate in one location for a limited period of time.
Often, other problems such as glaucoma, corneal blindness, or retinal diseases remain untreated due to limited resources. Because they recognize that their high volume of cases represent only a tiny fraction of the curable or preventable cases of blindness in developing countries, SEE International fund a separate education programme for ophthalmologists in Third World countries. The Eye Camp programmes team up with a host ophthalmologist, to provide some training if it is required, and to help provide equipment, such as microscopes and autoclaves (used for sterilising surgical instruments). Repeat visits are made to the same country to maintain the projects' momentum.

The ABC's of Cleaning Your Contacts
There are many benefits to wearing contact lenses and over the years since they first came on the market they have become safer and more durable. Today users can choose from a variety of different contacts some of which are even able to be worn for extended periods of time. However some things about these lenses have stayed the same.
For example there is still a real need to understand how to care for the contacts in a proper manner and not only how to put them in and take them out but what kind of cleaning solution is the best to use. Contact lenses are a big investment and looking after them properly can help increase your peripheral vision as well as your ability to play sports effectively. However there's no way around the right cleaning solution.
As well, there are different kinds of contact lens and one of the more common ones is called the daily wear contact. These must be cleaned and disinfected at the end of the day and stored in a special case since there is always a risk of infection to the eye when the lens are not looked after properly.
Remember here that the lens can only be worn again after they have been properly disinfected and to do that the safest bet is to go with a solution that either your eye care professional or the manufacturer of a contact lens recommends. It's also important to change the plastic lens cases often and to ensure that they stay closed whether or not the lenses are in them. It's also a good idea to use the same solution disinfect on the case on a regular basis.
Continuous wear contact lens must be cleaned and disinfected in much the same manner and with the same kind of solutions as daily wear lenses although not as often. The difference between these continuous wear varieties and the daily lenses are the continuous wear often require wetting drops to be placed in the eyes at regular intervals since these lenses can be worn for up to six days and nights.
The last type of contact lenses is called daily disposables because they're thrown away at the end of every day and a new pair is inserted the next day; eliminating the need for cleaning solutions.
Of course there is a procedure that you should follow when you actually go through the mechanics of cleaning your contact lens and the first step is to wash and clean your hands thoroughly and close any sink drains that you might be standing over. There are many products on the market today for cleaning contact lenses and multipurpose solutions are one of the more popular since they can be used for rinsing and disinfecting at the same time.
You need to keep a clean container around at all times to store your lens and it's a good idea to have a bottle of saline solution close by for rinsing them off. Hydrogen peroxide, which is a common household item used to treat cuts, can also be used to disinfect your contact lens in a two-step procedure that you can learn more about from your eye care professional.
Remember to fill the contact lens case with the right amount of disinfectant. It's important for the lens to stay in the solution for a period of time to prevent the buildup of bacteria that can cause a serious eye infection.

Eye Doctors Disciplined For Wrong Treatment
The Florida Board of Medicine has decided to take action against two Polk doctors for wrong treatment. Both the doctors were charged with mistakes in treating patients. The Florida Board has decided to accept the disciplinary settlement made by Dr. Alan Lingenfelter, a Winter Haven anesthesiologist. The accused doctor is fined with $ 5,000. Other than that, he will deliver a one-hour lecture on wrong-site surgeries, as well as doing 50 hours of community service.
Dr. Lingenfelter, was accused of applying applied anesthesia beside the wrong eye, while preparing a patient for the cataract surgery in 2005 at Sebring. He later on documented his error medical records and told the eye surgeon what had happened.
Another complaint accuses a retired Lake Wales doctor for wrong treatment. The board however accepted the accused Doctor, Dr William Hardman's offer to relinquish his Florida medical license to resolve a 2003 medical complaint. The charge against him of damaging bladder and intestine of a woman during a tubal litigation he performed. The next day, she complains of severe abdominal pain. Hardman gave her antibiotic only to harm her health. The complaint said this is a known complication of tubal ligation and that Hardman hadn't kept sufficient medical records to justify the treatment he provided.

Don’t Take Health Of Your Eyes For Granted
As long as we can see and our eyes give us no trouble, most of us find it hard to believe that things could go wrong. As we age, however, the risk of conditions such as cataracts, and age-related macular degeneration increases. So the sooner you start taking care of your eyes the better.
Age-related macular degeneration (AMD) is a common problem, affecting as many as one in four people by the age of 75. It affects the central part of the retina known as the macula: the part of the eye that distinguishes fine detail. First symptoms include a blurring or distortion of vision followed by a gradually enlarging central blind spot. Eventually the condition stabilises and people with AMD rarely lose their sight completely - they are usually left with enough peripheral vision to get around, but driving and reading can become impossible and even watching television may be difficult.
Causes: AMD has been linked to hardening of the arteries and poor circulation, excessive exposure to sunlight and smoking. Long hours spent in front of a computer screen and low levels of antioxidant nutrients may also be factors.
Cataract is another common problem that develops in later years when the protein fibres that make up the lens of the eye undergo chemical changes. The process is similar to that which takes place in the white of an egg as it is cooked. Cataracts usually develop in both eyes, although one is usually more advanced than the other.
Causes: Most cataracts are the result of age but they can develop after an eye injury. Other causes include diabetes, smoking, a diet low in vegetables and fruit, excessive exposure to sunlight, raised blood pressure and the simple fact that we tend to live longer than we used to.
Glaucoma results from raised pressure inside the eyeball. The ball itself is divided by the iris into two compartments, one in front of the lens and the other behind it. A fluid called aqueous humour normally flows freely through a narrow drainage channel. Glaucoma develops when the fluid is produced faster than it drains away or because the drain becomes blocked.
Causes: Glaucoma tends to run in families, so if any of your relatives have been affected it is sensible to have regular checks from the age of 40 onwards. It can also occur as part of the natural ageing process or after an eye injury.

Women’s Beauty Habits Causes Eye Infection
Research by the College of Optometrists has revealed that women's beauty habits are putting their eye health at risk.
Despite recommendations that eye make-up should be thrown away after six months, one in four women continues to use bacteria-ridden products that are over four years old.
A quarter of those surveyed confessed to sharing eye make-up with friends and family, even though one in 10 admitted to frequently suffering from conditions such as conjunctivitis, said the College.
Welsh women were the worst culprits. A third admitted to owning eye make-up that was over four years old while women in their late 30s and early 40s had the oldest make-up bags one in five admitted to using make-up that was over five years old.
Dr Susan Blakeney, optometric adviser to the College, said: 'Mascara can be a breeding ground for bacteria, so it's not surprising we've found nearly half of women suffer from itchy, watery and red eyes.'

Eye Makeups Could be Your Eyes Worst Enemy
Bacteria Love Your Eye Makeup. Eye makeup makes life so much easier and prettier. But if not used and removed properly, it can also be your eyes` worst enemy.
Although eye makeup is bacteria-free when you buy it, it is very prone to infection by bacteria from the moment you open the package and expose it to air and germs. Because it’s applied to one of the body’s most sensitive areas, those germs can easily cause a big problems – like severe infections, pink eye or ulcers - for users who are not cautious.
To help you enjoy your eye makeup for the life of the product and avoid problems, follow these safety tips:
· Keep it clean. If your applicator falls in the sink or on the floor, throw it away immediately. Keep your makeup containers clean and dust-free.
· Don’t keep any eye make up longer than the expiration date. If you haven’t used a shade for four months, throw it away. Bacteria may have been breeding undisturbed.
· Toss out mascara that`s dry or more than three or four months old. Don`t add water or worse, spit, to moisten dry mascara.
· Wash your hands before putting on eye makeup. Your hands have lots of germs and bacteria that could get in your eyes.
· Keep your cosmetics at room temperature and away from direct sunlight. Heat and sunlight can spoil products.
· Don`t share eye makeup with anyone. You could easily get an infection.
· Don`t use testers at department stores. If you really want to see how a color looks, use a clean cotton swab – even that is disputed as to how sanitary it really is because many people have touched those open samples
· If you have an eye infection, don`t use any eye makeup until the infection is gone. Be sure to toss the makeup you were using when you got the infection. Chances are high that it`s contaminated with the same bacteria that caused your infection in the first place.
Knowing the shelf-life of you eye makeup is very important. If you don`t remember buying it, throw it away. If you notice (even a little) any of these signs, pitch that makeup immediately:
· The color has changed.
· It smells funny.
· The container is cracked or the cap no longer fits tightly, which means bacteria can get in and do damage.
· The consistency has changed. What was once thick is now runny, or liquids that are beginning to dry out.
Sleeping with eye makeup on can cause big problems too, so be sure to gently remove all your makeup before going to bed using a facial cleanser, water and a soft washcloth. Or, if you prefer, using eye makeup remover and a clean cotton ball can also be effective. Either way, be sure to clean the corners of your eyes as well.

Introduction to eyeglasses lens design
Many people need only a single powered lens to correct nearsightedness (myopia), farsightedness (hyperopia) or astigmatism. Single powered lenses are used for both full-time wear and part-time use, like reading glasses. (Some reading glasses are half-frame, to enable the wearer to see over the top for distance viewing.) Single powered lenses can be made for very strong prescriptions, but they are only designed to deal with one vision deficiency. People with multiple prescriptions will require multifocal lenses.
Bifocals are two-part lenses; the top part is for your distance prescription, the bottom for your reading prescription, and a line separates the two.
Trifocals have three segments and two lines, with a middle segment inserted for the mid-range vision you need to see the dashboard of your car, or a picture you are painting.
There are several designs for multifocal lenses:
* Flat top lenses are the easiest to use because the reading area of the lens is a clearly defined semicircle at the bottom. You always know exactly where to look when you read.
* In a Franklin-style lens, the dividing line runs all the way across, and the reading area is the entire width of the bottom of the lens. These lenses provide the widest field of vision for close work. (Franklin-style lenses are frequently used for trifocals.)
* Progressive lenses have no line at all -- just a gradual transition between the various sections of the lens. They are the most flexible, but distortion around the reading area can be distracting. Newer progressive lens designs reduce or eliminate distortion.
* Aspheric lenses are thinner than conventional stronger lenses, and give better vision when looking to the side, from the center of the field of vision. This design is good for people with strong corrections because they are more attractive and lighter than conventional high-powered, thick lenses.
All multifocals take some getting used to. Until you learn what part of the lens to look through, move your head from side to side when you’re reading or look through the top part of the glasses when approaching steps. Your ophthalmologist may have additional tips to help you adjust.

Who Should Not Wear Contact Lenses?
Some of the conditions that may keep you from using contact lenses include
* frequent eye infections
* severe allergies
* dry eye
* a work environment that is very dusty or dirty
* inability to handle and care for the lenses properly
Most people who need vision correction can wear contact lenses. If you think they might be for you, talk to your ophthalmologist.

An Introduction To Reading Glasses
Do you often have difficulty reading things or seeing things close to you but have no problem with your far away vision? Do you often find yourself keeping a book or any reading material a little further away from yourself, in order to see better? If so, then you may need reading glasses.
What Are Glasses For Reading?
People who have trouble with their near or close-up vision, usually keep reading material at arms length or try and squint to make out the words. Such people have compromised near vision and require glasses for reading.
Reading glasses have a kind of magnifying lens, which magnifies the words on a page so that you can see and read them better. Glasses for reading are mostly useful for reading as well as concentrating on things and items close to you. If you try to see in the distance with your reading glasses, then you will not be able to see things clearly as everything will appear blurry. Thus, eyeglasses for reading are not the same as the regular kind of eye glasses for distance vision correction.
Choosing Reading Eyeglasses
Reading glasses are usually available in two different types.
The single vision eye glasses for reading with a full frame, meaning the complete lens in the eye glasses is as per the reading prescription.
The reading glasses with half-eyes, in which the lower part of the lens is made according to the reading prescription, and the upper part of the lens is normal. Such reading glasses are those that sit lower on the nose.
If you need to wear reading glasses for short periods of time, then the full frames may be suitable for you. But, if you wear your reading glasses for long periods, then half-eyes can be considered, so that you do not have to keep removing your reading eyeglasses, every time you need to look into the distance.
Pre-fabricated And Customized Reading Glasses
To get a pair of eye glasses for reading, you do not need a doctor’s prescription. You can go to any store that sells pre-fabricated reading glasses and pick a pair. Such pre-fabricated glasses for reading have a kind of magnifying lens that helps you to see nearer items better. Pre-fabricated or readymade reading glasses are much cheaper than the customized version, and you can thus buy various readymade reading glasses instead of having only one. This can enable you to experiment with different styles and colors of eye glasses for reading.
Readymade reading glasses are essentially ‘one for all’ type of reading glasses. They are not made to your exact eye prescription and can thus give you some problems. If the glasses for reading are too far off from your actual prescription, then using such glasses will put extra strain on your eyes, which could lead to eye strain, head aches, and sometimes even nausea.
If you can afford the extra cost, then buying custom made glasses for reading is certainly the better way to go. With customized reading glasses, the lenses for both the eyes will not be similar and will be made exactly as per your reading prescription. The optical centers in the lenses will be placed according to your prescription and not in a random fashion. Thus, you will get reading glasses, which are optimum for your eyes and will not put any unnecessary strain on them.

Opt for a headband attachment to secure the frames on the athlete's head.
5
Step Five
Consider athletic eyewear for children who wear contacts. The American Optometric Association (AOA) feels that contacts alone do not provide sufficient protection.
6
Step Six
Look at non-prescription sports glasses as well. The AOA feels that children should use protective athletic eyewear regardless of whether they wear prescription glasses or contacts.
Tips & Warnings
* Provide a safe place to keep glasses before and after playing to avoid losing them.
* Mark your child's name and telephone number on the glasses, for example, on the headband attachment. Then, educate your child on the importance of caring for his glasses, since they are expensive.
* Take your child to a hospital emergency room or an eye doctor for immediate care if he or she is hit in the eye.
Playing sports in regular prescription glasses is an accident waiting to happen. To help prevent eye injuries, child athletes should use protective athletic eyewear.

Introduction
Prescription glasses and sunglasses have to be functional but also look good. Fortunately, there are so many styles that it's easy to find the right pair. Learn the technical details first, then shop around.
Instructions
Difficulty: Moderately Easy
Prescription eyewear
Steps
1
Step One
Consider frame materials. Aluminum and titanium frames are very durable and offer custom fitting options. Plastic frames are light and durable but usually can't be bent to offer a custom fit.
2
Step Two
Assess overall weight. Glasses need to be comfortable. Large lenses and thick frames add up to heavy glasses, something most people find uncomfortable. If you need thick lenses, get the smallest diameter lens that looks good on you.
3
Step Three
Understand lens materials. Glass lenses resist scratching but are heavy and have lower shatter resistance. Polycarbonate (plastic) lenses are light and shatter resistant but demand care to prevent scratches. Custom options for lenses include an antireflective coating to cut glare, enhanced thinness for light weight and good looks, and photoreactive tinting that gets darker in bright light. Beware: These options can easily double your total cost.
4
Step Four
Shop for metal frames that can withstand vigorous bending without damage. Opt for a separate set of specialized sports glasses with an impact-resistant frame and lenses secured by a strap.
Sunglasses
Steps
1
Step One
Read the label carefully. You want 100 percent UV (ultraviolet light) protection from both UVA and UVB rays. Some lenses are labeled as UV400, which means the same thing.
2
Step Two
Own several pair of sunglasses since one pair can't do everything. Leave a pair in the car for driving--cheap ones if you tend to sit on them. A slim stylish pair will not protect your eyes from debris while riding your bike. Expensive, sporty wrap-arounds will make you look like a yahoo at work.
3
Step Three
Look for shatter-resistant polycarbonate lenses for water and snow sports, which require protection against strong reflected rays. Glass lenses, with their increased scratch resistance and fine optical quality, are a good choice for pricey, dress-up glasses. Polarized lenses, which reduce glare, are always a good idea.
4
Step Four
Choose lens color carefully. Sensitive eyes need dark lenses. Gray or gray-green are good for general use. Brown works well for daytime driving or golf. Yellow and amber provide depth perception in low-light conditions. Avoid light blue and pink for driving or sports as they distort color. Some models have interchangeable lenses.

Caring for Your Glasses
Proper lens and frame care ensures clear vision and comfortable wear. Good habits include proper handling, periodic maintenance, adequate cleaning and regular visits to the optician.
Handling
With gentle handling, your glasses will last longer and feel more comfortable. To avoid twisting the frame out of shape, use both hands to put on your glasses. Grasp the ear pieces (arms or temples) in the middle with equal pressure and push the glasses over your ears. To remove them, use the same grip and carefully slide the frames forward over your ears and off your face. This method puts the least amount of stress on your frame and prevents misalignment.
Close your frames before placing them on any surface, and never lay them lens-side down. To prevent accidental scratching, store your glasses in a case whenever they are not being worn. Never put them in a purse or bag without proper protection.
Do not wear your glasses on top of your head when you do not need them to see. This may misalign the frames.
Maintenance
Frames will last longer with proper maintenance. Check for loose screws and temple misalignment periodically. For emergency repairs, use a small eyeglass tool kit, which usually contains a screwdriver and various sizes of temple screws.
Avoid exposing your glasses to personal care products. Hairspray, perfume and other products can damage lens coatings, and cosmetics will dirty the lenses.
Your glasses will inevitably bend out of shape over time. To maintain proper fit, have your glasses adjusted by an optician regularly. How much you wear them, how active you are, and other personal variables will determine how frequently you need to have them adjusted. Ill-fitting glasses can strain your eyes, interfere with vision correction, and create dangerous situations. It is recommended that you do not try to bend your frames back into shape yourself. The service is usually complimentary at optical shops and eyecare offices where a trained professional can guarantee you a proper adjustment.
Cleaning
Keep your glasses clean. This ensures that you benefit fully from the corrective power of the prescription, and helps prevent scratching the lenses.
First, run your lenses under warm running water. Then dip them in soapy water and rub them gently with your fingers. Rinse them to wash away dirt and oil. A gentle dishwashing liquid makes a good cleanser. There are also special lens cleaners that can be sprayed on the lens (although some may damage lens coatings). Avoid using household cleaners, disinfectants, acetone or soaps with cream.
Wipe the lenses with a clean, soft, lint-free cloth. Do not use paper towels, silicone tissues, facial tissues, or old rags that may have embedded dirt. These materials may scratch your lenses. Many optical suppliers sell microfiber cleaning cloths. These efficient cloths are machine washable and very gentle on your lenses.
The same techniques apply toward cleaning the frames. The temples, in particular, need to be cleaned often because they are handled the most. Repeated contact with the skin causes oil to accumulate and can degrade the frame finish.
