Light reflected from surfaces such as a ski slope or water is generally horizontally polarized. This means, instead of light being scattered in all directions in a more usual way, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare.
Polarized lenses reduce glare reflected off roads, snow, water and other horizontal surfaces. Polarized lenses cut glare and haze, making your eyes more comfortable and allows you to see better.
