Oakley High Definition Optics® (HDO®) - lenses optimize safety and performance to meet the uncompromising demands of professional athletes who settle for nothing less than the clearest, sharpest, most accurate vision. It offers truer, more accurate vision versus conventional lenses that magnify images and make objects appear shifted from their true position. With HDO, Oakley lenses meet or exceed the testing standards of the American National Standards Institute (the yardstick of performance for the eyewear industry).

Part of the secret is Plutonite® - they're durable and optically pure lens material. Within our spirit of performance and innovation, we continue to deliver the best performance products on the planet. Impact protection beyond what's necessary. We consider it mandatory. 

Thermonuclear Protection - Oakley Plutonite® lens material stops every wavelength of ultraviolet radiation from the sun?s thermonuclear furnace, not just the lower energy form called ?UVA.? Even our clear lenses filter out 100% of all UV. The image at the left shows how harmful rays are blocked while the visible spectrum passes through.   An invisible form of radiation, UV rays pelt your retinas at 186,000 miles per second. Eye damage linked to UV includes cataract, photokeratitis and pterygium. UV damage builds up over time. You generally don?t feel UV rays, so there is no natural warning that damage is being done. And although clouds reduce the level of UV reaching your eyes, clouds don?t block UV completely ? which means your eyes can be exposed to UV rays even on overcast days.
