Unique 3-point fit from Oakley includes optical alignment for sharp accurate vision, impact absorption for improved safety and geometry that extends the peripheral view. Optically correct, shatterproof and scratch-resistant Plutonite(R) polycarbonate lenses provide added durability. Caffeine frames with dark bronze tinted lenses are best for extremely bright light. Tortoise frames feature brown gradient lenses which are dark at the top of lens and progressively lighter toward the bottom. Nose pads made from hydrophilic rubber become tacky as you perspire, holding eyewear in place during strenuous activity.
