Smith lenses use only the highest quality Japanese polarized film for the truest color, object definition, and glare reduction. We combine it with both Techlite Glass and Carbonis Lens materials to give you the potions and optical performance you need to succeed. It doesn't take a rocket scientist to figure out that these shades have the right stuff. A unilateral, multi-national effort has allowed us to boldly go where we haven't gone before. Ultra premium Techlite Polarized Glass lenses are captured within an advanced combination of materials and frame details.
