The ultimate in athletic eyewear, the Oakley Radarlock Path Sunglasses use Switchlock Technology, allowing you to quickly and easily switch out lenses to fit changing light conditions. For this first purchase, choose between regular, polarized or photochromic lenses, each frame comes with 2 lenses -- one for bright light and one for low light -- then add more to your quiver over time as you figure out what other tints and finishes you need. The wrap-around High Definition Optics give you a huge field of view with amazing optical clarity and superior impact resistance. But the lenses are nothing if the frames fall off or don't fit your face -- no problem -- these Oakley sunglasses come with interchangeable nose pads so you can customize the fit and the earsocks are made from the same sport-optimized Unobtainium that grips harder the more you sweat. Lightweight, durable and sleek, the Oakley Radarlock Path Sunglasses are engineered to change the game.
