Description of Oakley A Frame Lens - H.I. Persimmon 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. Important Note: Use care when installing/removing accessory lenses. Scratched lenses can not be returned and are not covered under Oakley’s warranty policy.
