Oakley Gascan Sunglasses - Men's The Oakley Gascan Sunglasses feature High Definition Optics®, which combine patented optics and Plutonite® lens material that provides 100% UV filtering and unsurpassed impact protection. 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 that Oakley customized their logo just for these sunglasses. Lightweight O Matter® frame material offers premium comfort while 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.
