6 Base Curvature - The base curvature corresponds to the curve of the lens. The higher the number, the higher the curve. 6 base styles have a “flatter” look. 8-9 base curves hug closer to the face.
Polycarbonate - Made of the toughest, most shatter resistant material. Light, comfortable and much more impact resistant than glass lenses.
Polarized - Polarized lenses act as blinds and block light that reflects off flat surfaces such as snow, asphalt and water. The polarized filter absorbs and eliminates scattered and reflected light, in turn drastically reducing glare to help the wearer see more clearly in bright conditions.
