Inspired by the helmet visors of fighter pilots, the Oakley Flight Deck maximizes your field of view so you won't miss a single target of opportunity. Peripheral and downward vision are wide open for spotting challenges and dangers, and the Ridgelock interchangeable lens system lets you adapt to whatever the sky dishes out. The rimless design has wide-ranging helmet compatibility plus the comfot of minimized frame mass. Discreet frame notches at temples provide compatibility with most prescription eyewear. Do note: the standard combinations of frames and lenses as set by Oakley do not apply.
