Oakley is constantly redefining what sunglasses can do for you, and the Radarlock XL Straight Photochromic Sunglasses are no exception. Photochromic lenses darken and lighten is response to changing light conditions, and if that's not enough, they can be swapped out for other lenses in seconds thanks to Switchlock interchangeable lens technology. With an extra-wide field of vision and a  featherlight O-Matter frame, it's easy to forget you're even wearing sunglasses—until you take them off and realize how much better things looked when you were wearing them.
