VISION 8, 5 and 3 lenses are made from the toughest, most optically perfect polycarbonate material. An anti-fog and hard coating is applied and all lenses offer 100% UVA protection. VISION lenses have an LTV of between 25% and 90% depending on the tint chosen. VLT is "visible light transmission", which essentially corresponds to the amount of light that the lens lets into the glasses. Look incredible with excellent optics on the track or trail.
