Providing crystal-clear vision, these comfortable sunglasses offer maximum protection against the sun's harmful rays. Impact-resistant polarized Odyssey N3 polycarbonate lenses are precisely engineered to filter blue light for exceptional color and clarity. Plus, they offer one of the hardest antiscratch coatings available. Improved venting design prevents fog and moisture build-up on lenses. Sunglasses come with two sets of lenses – one polarized and one nonpolarized – for eye protection in all light conditions.
