Giro S Lens Blok

VIVID disc technology filters only part of the blue light to increase contrast and safety. The benefits can be seen in all light conditions - bumps on the slope are better visible. The increased contrast reduces eye strain, shortens reaction time and gives safety.Note:VLT is the abbreviation for Visible Light Transmission and indicates the percentage of visible light passing through the lens. The lower the percentage, the darker the tint of the lens. Thus, a lens with VLT 20 is optimal for strong sunlight. VLT 75, on the other hand, is suitable for darker light conditions.
