What are polarized lenses?

Basically, a polarized lens has a special coating that is polarized vertically. Since reflected light is generally horizontally polarized, the vertical polarization in your lens will act to block or reflect the vertically polarized light.

Glare Reduction

Polarized lenses reduce or eliminate most forms of glare. Whether it's light reflected from a roadway, building, another vehicle, mirror, glass, water or whatever, the lens will block the vertically polarized light from getting to your eyes. Glare is a problem in many areas of work, play and everyday activities. If you are driving home from work and the late day sun all of a sudden gets in your eyes, this can be a potentially dangerous situation, possibly even causing an accident. However, if you are wearing sunglasses with polarized lenses, the sudden glare will not affect you as much and the situation should not be as dangerous.

Eases Stress On Eyes

Since harmful light rays are blocked and what you see is enhanced, your eyes will not have to do as much work. This results in less stress to your eyes and therefore less eye strain. Eye strain is a common cause of headaches, so this is a huge advantage. In some cases, eye stress can make your eyes more susceptible to problems, so reduction of eye stress is and important advantage.

Better Contrast

Contrast is another advantage of polarized lenses. Because glare is blocked, contrast is enhanced. Better contrast results in better safety for many outdoor activities, from driving to water skiing to cross country skiing. Better contrast helps you see things better.

Enhanced Clarity

Better contrast, reduced glare and less stress on the eyes results in better clarity overall. If you can see things more clearly, your performance will be better no matter what you are doing.

Eye Protection

When you wear sunglasses or goggles with polarized lenses, your eyes are virtually 100% protected from UVA and UVB rays. These forms of light are the most harmful to your eyes. People with every sensitive eyes, very old or young people and people who have eye conditions or have had eye surgery recently should take special care to protect their eyes from these rays.
