 How Do Polarized Lenses Work How Do Polarized Lenses Work? Light reflected from surfaces like a flat road or smooth water is generally horizontally polarized. This horizontally polarized light is blocked by the vertically oriented polarizers in the lenses. The result: a reduction in annoying and sometimes dangerous glare. There is some debate on the effects of polarized lenses on snow-covered surfaces. Some experts say they can reduce the intense glare that is caused by sunlight reflecting off snow. Others purport that the lenses are not satisfactory for sports such as downhill skiing because they may not provide the contrast the eye needs to distinguish ice patches or moguls.  Polarized sunglasses come in different styles and lense colors. Polarized progressive lenses are perfect for the presbyope who is also an outdoor sports aficionado. And polarized photochromic lenses, which change from dark outside to light inside, are right for the light-sensitive person who changes environments frequently (inside to outside and vice versa). Whether you spend your time boating or waterskiing, in-line skating or mountain biking, driving or jogging, polarized sunglasses are an excellent choice. Chris Megee |
