Welcome to the dark side. The ULTRA Black lens has the tint (VLT) cranked down to 6%, compared to industry standards of 11% - These lenses are DARKER and legally should not be used when operating a vehicle. On the other hand, these are the ultimate bright outdoor lens. Whether you are on the snow, sand, a white rooftop or just want the ultimate poolside shark lurking lens these are for you. The Vise® Z87 features an all TR90 construction and tightly holds form and function together, as the Vise® Z87 meets ANSI Z.87 mass-impact requirements (and Z87+ with add on side-shields) featuring 1.9mm thick lenses to aid in protection against basic impacts and flying debris, which enables the Vise® to transcend just that of a regular pair of sunglasses.
