From ocean-side volleyball games in the sand to tossing bocce balls in the backyard, the Proof Polarized Eagle Sunglasses employ an aviator frame for commanding style and comfort wherever you rock them. The polarized CR-39 lenses cut down on harsh glare and dazzling light that bounces off the water while also enhancing the colors around you for a crisp view. Recycled aluminum and sustainably-sourced wood comprise the Eagle's frame for the perfect union of nature and man, and the large design provides maximum coverage and timeless style.
