HIGH DEFINITION OPTICS® (HDO®) combines patented optics and PLUTONITE® lens material that provides 100% UV filtering and unsurpassed impact protection. Accessory lenses are made of premium PLUTONITE® lens material, an innovation that blocks 100% of all UV radiation. Oakley’s CAD/CAM engineering makes lens replacement simple, yet maximizes impact protection while the lenses are installed. For select goggles, choose an optional IRIDIUM® lens coating to minimize glare and tune light transmission.
