The standard clear 2" diameter lenses are German-safety shatterproof, laminated glass (7/64" thick). Accessory glass lenses are gray (UV protection sunglasses) and real level-5 Welder's lenses (these however, are not laminated safety glass). These Goggles with aluminum frames are extremely comfortable to wear for extended periods as the middle flexible strap hinge allows them to fit almost any face and the cushioned leather padding fits the face snugly. They are several steps up from the typically available plastic protection and are really exceptionally neat, we think.
