Apart from their retro style, the Jawbreaker Prizm Sunglasses feature some of Oakley's most innovative technologies for the modern cyclist. Oakley's Prizm technology gives the Plutonite lens a shape that enhances the road so you can see any rock or pothole that comes your way. Plutonite filters out 100% of UVA, UVB, UVC, and harmful blue light up to 400nm, while High Definition Optics helps the lenses exceed American National Standards Institute's ratings for optical clarity, visual fidelity, and impact resistance. Oakley also coated the Jawbreaker Prizms' lens in Iridium to balance light transmission and reduce reflective glare. The Switchlock system, with its simple mechanism for simple but speedy switching makes all other interchangeable lens systems look like ancient artifacts. The Jawbreaker Prizms also feature Oakley's stress resistant, lightweight O Matter frame with slip resistant Unobtainium pads at the nose and temples.
