Take attitude to the street with the new Oakley Dispatch. Check out the contours, the sculptural stems and the metal band accents and notice that self-expression is taken to the next level by the interchangeable O? icons. The frame comes with two different sets. Lightweight O Matter frame material is the secret to all-day comfort, and this pair of sunglasses takes advantage of Oakleys patented Three-Point Fit to keep the lenses in precise optical alignment. High Definition Optics (HDO) is the reason why its clarity exceeds ANSI Z87.1 standards. Notice the lens curvature that extends peripheral vision. Pure Plutonite lens material blocks 100% of all UV and helps this design meet ANSI Z87.1 basic impact standards.
