Oakley Jawbreaker Sunglasses The Oakley Jawbreaker Sunglasses are performance-focused eyewear, offering excellent peripheral vision and the eye-protecting technology of Oakley's Plutonite® lens material. Not only do they protect against 100% UVA and UVB rays, but the lenses also provide unrivalled shatterproof impact protection. High Definition Optics® (HDO®) also ensure you enjoy optimal visual clarity and razor-sharp vision.  The lightweight O Matter™ frame and Unobtainium® earsocks and nosepads combine to give a locked-in fit, remaining comfortable and secure even during the sweatiest of training sessions. And with the 2 different lens options and Switchlock™ technology, you can swap out the lenses without a fuss. The Prizm Road lens improves contrast, ensuring you always have the clearest view in the sunshine, while the clear lens is perfect for your dawn or dusk training sessions.  Lenses: Prizm Black Light Transmission: 11% Light Conditions: Bright light Contrast: Increased Base lens colour: Black Clear Light Transmission: 93% Light Conditions: Low Light Base lens colour: Clear
