Sunglass Lenses

1. Polarized Lenses

Polarized lenses in sunglasses have a special filter that protects your eyes from harmful UV radiations, blocks reflected light and eliminates glare. Polarized sunglasses and polarized goggles allow wearers to experience the outdoors "clearly" while still protecting their eyes from the sun's rays. Polarization of the lenses eliminates the glare created by water, snow, sand, and other reflective surfaces and reduces eye strain.

Advantages of polarized sunglasses:

• 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.
• Reduces 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.
• Better Contrast: Better contrast helps you see things better. 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.
• 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.

2. 100% UV coating

Long-term exposure to UV rays can damage the eye’s surface as well as its internal structures, sometimes contributing to cataracts (clouding of the lens) and macular degeneration (breakdown of the macula). Your sunglasses must provide protection from ultraviolet radiation, a component of sunlight that contributes to eye disease. Always choose sunglasses that are labeled as blocking 99-100% of UV rays. Some manufacturers’ labels say "UV absorption up to 400nm." This is the same thing as 100% UV absorption.
