The smoke-tinted blue-mirrored lenses of these Men's AT 6 polarized sunglasses from Foster Grant are not only eye-catchingly cool. They perform. Polarization means high-definition visibility and optical clarity under glaring light conditions. These advanced lenses block 100% of the sun's harmful UVA/UVB rays. What's more, they have a scratch and impact resistant hard coating that helps keep them in pristine shape. And the wide black body with rubber nosepads sit comfortably and securely. Adventures under the sun await.
