Plutonite® Lens Material – UV protection that filters out 100% of UVA/ UVB/ UVC and harmful blue light up to 400 nm. Iridium Lens® Coating [Select Colorways] – Designed to balance light transmission and reduce glare, this premium lens coating is made with superheated metal oxides. It is available in a spectrum of colors for optimizing vision in virtually any light condition. Prizm™ Lens [Select Colorways] – A revolutionary lens technology that fine-tunes vision for specific sports and environments. Prizm™ lenses enhance contrast to better let you see obstacles like rocks and potholes before they reach out and bite you. Polarized® Lens [Select Colorways] – Improving safety, comfort and performance, Oakley HDPolarized lenses filter out 99% of reflected glare without the haze and optical distortion that can come with polarized lenses made with conventional manufacturing techniques. Frame Medium High Wrap – Rectangular lens shape with optimized peripheral vision and side protection.
