The Nova and its aggressive look make a loud and clear statement, not to mention, give you clear vision all day long. A state-of-the-art, high contrast, light reactive lens that changes lens tint density with the changing light conditions. Light transmission from 26% - 66%. The more UV light exposed to the lens, the darker the lens will become. Two-layer, extra-soft face foam for comfort. Great peripheral sweep lens design. Fits medium to large faces.
