Polarized lenses help to prevent glare from shiny surfaces like water, snow, and windshields. The protection of polarized lenses comes from filtering the direction of light. This helps you get a clear image, rather than the glare caused by reflected light in all directions. Polarized lenses are great for people who spend lots of time outside, and the polarized technology helps protect your eyes from damaging UV rays, as well as keeping the view nice and sharp.
