Oakley sunglasses take shape in a world that doesn’t exist. Not on paper, anyway. It’s the virtual reality of digital design that lets them achieve things like Reduced Cranial Geometry. That’s how they took the comfort and clarity of their full-size CROSSHAIR™ frame and rendered this unique variant, perfect for smaller faces. The aviator styling comes from fly-by-wire CAD/CAM engineering and it gives you the unbeatable performance of HIGH DEFINITION OPTICS® (HDO®). It also offers superior impact resistance and 100% UV filtering. For extra comfort and a secure fit, the lightweight frame of C-5™ alloy includes soft UNOBTAINIUM® components that increase grip with perspiration. Prescription ready.
