Currently one of the most iconic sunglass models in the world, Aviator shades were originally designed for U.S. aviators in 1937. Today, Aviator is available with photochromic lenses that shift from clear to grey in changing light conditions \u2013 so you'll never need to take them off. Aviator Clear Evolve combines timeless design with exceptional quality, performance and protection. The slim metal frames are set with crystal lenses for maximum clarity; they filter 100% of UV rays and feature a front-side anti-reflective treatment. From sunrise run to sunset bar, if they\u2019re always on you\u2019re always covered.
