High Definition Optics® Lenses
All Oakley lenses offer HDO® Technology with the following benefits:
- Clarity: Conventional lenses can magnify images. HDO® precision gives less distorted vision across the entire field of view.
- Refraction: With regular lenses, objects aren’t really where you see them. HDO® offers a truer visual image so your brain won’t have to work overtime.
- UV Protection: All Oakley lenses block 100% of UVA, UVB & UVC rays and harmful blue light up to 400 nm.

- Product overview

Heroes don’t wear capes. They wear helmets and boots, and gear that drips with sweat. They risk life and limb, and place their own lives second to those they save. There are no words to describe that kind of courage. The Thin Red Line honors the bravery of firefighters, and it pays respect to those who have been injured and killed in the line of duty. This Oakley collection proudly carries that symbolic line. It is a salute to the heroes among us, a tribute to the men and women who save lives and protect property, and a reminder to never forget the fallen.
We’ve been toying with a mix of art and technology for some time. The idea was to create clean, authentic style for those who don’t just walk the path of life – they stomp it and leave footprints. That’s what led to Oakley Fuel Cell.
