Sport professionals demand nothing less than the best, and we've answered their challenge for decades. World-class athletes have driven us to create innovation after innovation, including interchangeable lens designs with unbeatable optical clarity. Flak Jacket takes that to the next level with the latest in performance technology. PLUTONITE LENSOne of the most optically pure materials used in eyewear today, it maximizes clarity and impact resistance while filtering out 100% of all UVA, UVB, UVC and harmful blue light up to 400nm. Not a coating, the UV protection is from the lens material itself. HIGH DEFINITION OPTICSHigh Definition Optics (HDO) is a collection of patented technologies that allow Oakley eyewear to meet or exceed the testing standards of the American National Standards Institute for optical clarity, visual fidelity, and impact resistance. IMPACT PROTECTIONBacked by decades of innovation, Oakley performance eyewear offers uncompromising protection against high-velocity and high-mass impact. The protection is a benefit of the premium materials and unique architectures of Oakley lens/frame combinations. UV PROTECTIONEye damage attributed to ultraviolet light includes cataracts, pterygium and macular degeneration. Our Plutonite® lens material filters out 100% of all UVA, UVB, UVC and harmful blue light up to 400nm. The protection is from the lens material itself. THREE-POINT FITA patented innovation that ensures the frame makes contact only at the bridge of the nose and the sides of the head. It holds lenses in precise optical alignment with a secure fit that eliminates the pressure points common with frames that hook the ears.O-MATTERA stress-resistant frame material that withstands environmental extremes, it is lightweight yet highly durable. Controlled flexibility enhances impact resistance while contributing to the all-day comfort of frames made with this innovative synthetic. LENS SHAPE: XLJXLJ lenses extend coverage for larger faces and for those who prefer an expanded field of view. IRIDIUMDesigned to balance light transmission and reduce glare, this premium lens coating is made with superheated metal oxides. It is available in a spectrum of colors for optimizing vision in virtually any light condition.
