Specially engineered for youth faces; Quarter Jacket⠢ blends the convenience of an interchangeable lens design with the clarity and protection of High Definition Optics so the new generation of athletes can take advantage of Oakley innovation. Accessory lens tints adapt vision for the chosen sport and environment; and with the sure grip of Unobtainium components; the durable yet lightweight frame stays comfortably in place. Its styling flows with fluid contours while its technology takes an aggressive approach to performance. 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 Optics High 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-Matter⠢A 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. Prizm⠢Prizm⠢ is a revolution in lens optics built on decades of color science research. Prizm⠢ lenses provide unprecedented control of light transmission resulting in colors precisely tuned to maximize contrast and enhance visibility.
