The polarized lenses on these cool aviator shades by BeOne for men are specifically designed to protect your eyes against harmful ultraviolet rays and to keep you looking good while doing so. The frame is all metal, able to flex and bend for your comfort, but also strong enough to hold its shape and stand up to daily use. The arms are straight and thin with the BeOne logo on the sides in small writing. The lenses are rounded and set with a double bridge support in between.
