Non-Polarized Polarized Polarized lenses have the benefit of filtering out reflected light and glare off water, pavement and snow. This lens works great for fishing, boating, driving or any other glare intensive activity.
Polarized lenses are the best way to eliminate both glare and UV light.
The principle of a polarized lens can best be described by observing the use of a venetian blind. The blind blocks light at certain angles, while allowing light to transmit through select angles.
