Two lenses are cut from the curve of a single lens shield, then mounted in the frame to maintain the original, continuous contour. The look is so unique, not to mention the corporate logo just for this eyewear. Lightweight O Matter frame material offers premium comfort. Peripheral vision is maximized by XYZ optics, an innovation that maintains visual clarity at all angles of view. Impact protection meets ANSI Z87.1 standards, and the three point fit retains the lenses in precise optical alignment. True metal icons sign this Oakley original.
