Too bad glare doesn't freeze. Snow actually brings out the worst of it, reflecting up to 90% of the sun's brightness. Conventional polarized lenses reduce glare but they also cloud your vision with haze and distortion. In the Oakley A Frame Polarized Snow Goggle, Oakley utilizes a liquid infusion process to achieve molecular level bonding with the polarizing filter. That's how Oakley eliminates haze and distortion to produce the best polarized lenses on the planet. These goggles combine the performance of Oakley polarization with the unbeatable clarity of HIGH DEFINITION OPTICS(R) (HDO(R)). It also eliminates lens fog with the airflow of ram-air surge ports, the chemistry of F-3 Series anti-fog treatment, and the thermal barrier of a dual lens design. You also get 100% UV filtering and impact protection that meets all ANSI Z87.1 / ASTM F659 standards. Comfort is optimized by flexible urethane construction and triple-layer polar fleece foam that wicks away moisture.
