They include impact resistance that meets all ANSI Z87.1 standards, a precise Three-Point Fit for comfort, and patented XYZ OPTICS® for clarity at all angles of view. With contours that extend peripheral vision and optimize side protection, the lenses are pure PLUTONITE® and the look is pure Oakley. Prescription ready.
