Oakley has always risen to the challenge when sports professionals demanded it. The new Prizm lens is a revolution in optics. Prizm lenses provide superior control of light transmission resulting in colors precisely tuned to maximize contrast and enhance visibility. The Oakley Prizm Half Jacket 2.0 takes the proud heritage to the next level of design. The frame is made of lightweight O Matter, an Oakley invention that raises the bar of durability. Interchangeable nose pads and stem sleeves of Unobtainium increase grip with perspiration to ensure the frame stays securely in place. Oakleys proprietary 3-Point Fit optimizes comfort while holding the lenses in precise optical alignment.
