Polarized lenses possess a filter that will eliminate the amount of reflected light that enters the eye. This filter will eliminate the reflected glare which is most noticable on water, snow, or concrete and asphalt surfaces.
For years, polarized sunglasses have been used by boaters and fisherman to reduce glare from the water. In recent years, the benefits of polarized sunglasses have been realized by a variety of other outdoor sports enthusiasts as well as by drivers and general use wearers. The popularity of polarized sunglasses has increased dramatically, as has availability of different lens materials and lens types.

How does polarization 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.
