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.
