Covering a wide range of peripheral vision, the Oakley incarnation, the Radar Range sunglasses, is a milestone in performance! Optically correct, shatterproof and scratch-resistant PlutoniteÂ® polycarbonate lenses enhance durability. Oakley Hydrophobic permanent lens coating prevents sweat and rain from building up and repels skin oils keeping your vision clear. The patented XYZ OpticsÂ® maximize your peripheral vision while retaining critical clarity at all angles of your field of vision. O MatterÂ® nylon frames are lightweight, stress resistant and flexible for long-term wear. Semi-rimless design allows unfettered vision when looking down--much appreciated by runners and cyclists. UnobtainiumÂ® nosepiece and stems are made from hydrophilic rubber which becomes tackier as you perspire, holding eyewear in place. Two sizes of interchangeable nosepieces are included to give you the best fit and performance. Protective case included.
