MINUTE® 2.0 uses the patented innovations of HIGH DEFINITION OPTICS® (HDO®) to beat all standards of ANSI Z87.1, the industry’s yardstick for optical precision. Even the world’s best lenses can’t perform if they’re covered with oily smears and water sheens, with added permanent coating called Oakley HYDROPHOBIC™ to repel rain, sweat, skin oils and dust.
