Yes! Most people believe that the darkness of the lens is what protects their eyes. The degree of darkness has no effect on UV rays. For adequate protection, you need to buy sunglasses that indicate they block 100 percent of the sun's UV rays.

Tips for Buying Sunglasses.In the market for a new pair of sunglasses? If you've ever shopped for a pair of shades, you know the experience is anything but simple. With thousands of styles and colors to choose from, how do you know where to start? You'd like a hip style that makes you look fashionable, but you are also concerned about finding proper protection for your eyes. Following are a few tips to keep in mind while shopping for sunglasses. 1.&bull;Look for sunglasses that block 99-100 percent of all UV light. Look for a label showing how much UV radiation the lenses reflect. Read labels carefully. If you are concerned, ask your optician, optometrist or ophthalmologist for his or her opinion.<br />2.Select a tint color based on your particular needs. Different tints filter different wavelengths of light. Gray is usually recommended for driving for proper traffic light recognition. Also, check that the tint appears uniform across each lens. <br />3.Try the sunglasses on in front of a mirror. If you can see your eyes behind the sunglasses, they may not be dark enough for you. 4. Be aware that dark-colored sunglasses don't necessarily provide better protection from the sun's harmful rays.<br />5.If you are considering purchasing a gradient tint, make sure the tint lightens gradually, from the top to the bottom.<br />6.&bull;Check closely for imperfections or distortions in both lenses: holding the glasses at arm's length, slowly move them across a straight line in the distance. A distortion in the lens may cause the straight line to appear curved or appear to move. Keep in mind that some extremely curvy or wrap-around styles of sunglasses may cause items to appear curved because of the way the lenses must be cut to fit into the wrapped frame.<br />7.&bull;Don't let price determine your purchase. Higher-priced sunglasses often reflect fashion, not UV protection.<br /><br />

Tips for Choosing Good and cheap sunglasses.


<br />UV Protection<br />&bull;Make sure the sunglasses you choose will block at least 99 percent of the sun's ultraviolet (UV) rays. UV-blocking glasses protect the cells in your eyes from damage that can lead to cataracts or macular degeneration. If you purchase sunglasses that don't block UV rays effectively, you will be missing out on the most basic function of sunglasses: protecting your eyes. Even the cheapest plastic lenses often come with 99 percent or 100 percent UV protection, so check the label before you buy. <br />Lens Type<br />&bull;When browsing the sunglasses rack, keep in mind that some lenses are better than others. Inexpensive sunglasses are usually fitted with plastic lenses, which come in many varieties. For driving or outdoor sports, polarized lenses are best--they block reflected light from the road, snow or water. For general-use sunglasses, grey-tinted lenses are recommended because they absorb light evenly and provide clear and comfortable viewing. <br />Frames<br />&bull;Although you will not be paying much for your sunglasses, you will still want them to last more than a few days. Cheap sunglasses made with metal frames are often flimsy and break easily at the joints. A pair of shades with sturdy plastic frames are likely to last longer than metal-framed sunglasses. Plastic frames are also preferable because they will not rust when wet, take longer to sink if dropped in water, won't get hot if left in the sun and are easier to find at the bottom of a pool.

How do you find out if Rayban Aviator are genuine or false? I have a couple of tips, but I wanted to know if there was some extra thing to check. Please do not tell me any obvious stuff like "go to...


These are the markings to check for.

Older Models made by Baush and Loma.

-Ray Ban B&L Made in the USA across the top part of the upper bridge.

-Size Markings on the paddles. (Only if they were not changed out, and are not the wrap around ear frames)

-Ray Ban white logo on the Right eye Lens. (Left if you are looking at the glasses) this should not come off easily like, with a cleaning cloth.

-B&L etched in the lenses, many knockoffs will have it painted.

-B&L engraved in the nose guards

Further information needed
--------------------------------------------------------------------------

Newer Ray Ban's made by Luxottica

-All newer Ray Ban's sold in the U.S.A will be made in Italy.

-Ray Ban Made in Italy under the top bridge

-Made in Ray Ban made in Italy CE on the inside right leg.

-Correct size and model info on the left inside leg.

-R&B etched in the lenses.

-Ray-Ban painted white on the Right Lens (Again won't come off easily)

--------------------------------------------------------------------------

Applies to both

-Should not have a mix of the above features....common mistake (Example made in USA across the bridge and made in Italy on the leg.)

-If painted, it should be enamel and should not come off easily.

-Hinges should have a distinct shape, not oval, and should not have any "burn" marks on the metal from being fused.

-The paperwork..sometimes called care book. (not the registration card) should be crisp with a professional work. Common fakes are printed with regular or shiny paper, haphazardly folded, sometimes colors will be bleeding, and or the English is full of typos.

-Mispelled words on the protective case if it has one. This should also match with the glasses. Luxottica with Italy made and Baush and Loma with U.S.A.

-Box is beat up or has Asian characters.

-Hinges should move smoothly but should not be loose. (Older/Used may require tightening.)

-Plastic lenses. An easy way to test this is to direct the car A.C. air at the lenses. Glass lenses will cool rather easily will feel cooler to the touch than plastic.

-Have them checked at a local sunglasses place, UV can be tested too. Many cheap priced sunglasses misrepresent the amount of UV that is blocked. Ray Ban's have a good reputation of Blocking that 99-100%

When you're choosing sunglasses, does UV protection matter?


Yes, ultraviolet (UV) eye protection matters. UV radiation from the sun can damage not only the skin of your eyelid but also the cornea, lens and other parts of the eye. UV exposure also contributes to the development of certain types of cataracts.
When you're choosing sunglasses, look for UV-protection details on product labels. Choose sunglasses that block 99 to 100 percent of both UVA and UVB rays. Skip sunglasses that are labeled "cosmetic" and those that don't offer details on UV protection. Opt for larger lenses rather than smaller lenses - or, better yet, the wraparound variety.

What is so unique about Polycarbonate Lenses?


Polycarbonate lenses are the most-used alternative material for modern ophthalmic lenses. Consumer interest in thinner, more attractive spectacle lenses led to the development of special lens materials that would bend light differently than conventional plastic lenses. These materials are called "hi-index".
Among the high index materials developed for eyeglasses is one material that has a number of very unique properties and that also provides special benefits to eyeglass wearers. It carries the generic name "polycarbonate" but is sometimes called something different by other manufacturer trade names.
Great for sports protective eyewear
A "must" for kids
Comes with FREE Scratch and UV Protection
Impact Resistant - Polycarbonate Surpass AR lenses are 10 times more impact resistant than plastic lenses.
Lighter - Polycarbonate Surpass AR lenses are up to 35% lighter and thinner than standard plastic lenses for greater comfort.
UV Protection - Polycarbonate Surpass AR lenses shield your eyes from virtually 100% of the sun's harmful UV rays.
Scratch Resistant - PolyCarbonate Surpass AR lenses are hardcoated for excellent durability and scratch resistance.
Easy Care - PENTAX EasyClean™ treatment resists dust and smudges, making your Polycarbonate Surpass AR lenses easy to clean.
Polycarbonate was the first plastic high index lens and still has one of the highest index ratings (1.59). High index advantages are included with every polycarbonate lens so there is never any extra charge for high index when polycarbonate lenses are ordered. Originally used primarily for industrial safety glasses, now used for children, sports wearers, or anyone requesting greater impact resistance in their lenses.

Which Features I need to look for when purchasing a pair of tennis sunglasses?


Here are some important features: 1.Competivision is a term created by Bolle Eyewear, one of the best manufacturers of sports sunglasses. Competivision is the first lens technology created specifically for tennis. The concept behind this type of lens technology is simple muting all light except optic yellow allows the ball to pop out of the background so you can see it more clearly. This is a must-have feature for all tennis players. 2.Polycarbonate Lenses-Tennis sunglasses, like other types of sports sunglasses, require polycarbonate lenses for impact and scratch resistance. Tennis players need these types of lenses more for impact and shatter resistance than anything else. 3.Polarized Lenses-Polarized lenses are extremely important in most sports - tennis is no exception. This type of lens technology is important to reduce glare. Glare from the rackets, the net or the court can hinder your performance so its important to choose sunglasses with polarized lenses. 4.Tight-Fitting-You're going to want to choose a pair of sunglasses that fit snug to your face. A huge part of your performance as a tennis player is agility. You can't stop between every hit to stabilize your sunglasses or pick them up if theyve fallen off. You need a pair that's going to move with you, fitting tight and comfortably on your face.
5. UV Protection-UV protection is a very important element in any outdoor sport. It's not enough to simply have UV protection anymore, you have to make sure the sunglasses you choose provide 100 percent UVA, UVB and UVC protection.

esigner-sunglasses/oakley.aspx">Oakley is the original designer of specific sports-related sunglass models and the first company to release a line of sunglasses designed specifically for biking. Their tight-fitting, comfortable sunglasses have been worn by cyclists in the Tour de France. Highly effective but highly expensive, Oakley offers top-of-the-line sunglasses for sports enthusiasts.

Planning to buy sunglasses for my ski vacation next month.Any thoughts on what's important to look for when buying ski sunglasses?


Shop before you get to the mountain, so you don't end up paying an inflated price.
Insist on lenses that provide 100 percent ultraviolet protection, to shield your eyes from the sun's harmful UV rays.
Look for anti-fogging features such as double lenses, anti-fog coating and wide vents
