Our lens-tint technology centers around visible light transmission, or VLT (the amount of light reaching the eye after passing through the lens), and is measured as a percentage. “All purpose” sunglass lenses typically range in VLT from 15-25%, sunglasses designed for high glare situations, such as crossing a glacier, have a range in VLT from 4-10%. Water sport sunglasses generally have a VLT between 10-20%.
Multi-layer Polycarbonate Construction
Advanced manufacturing techniques allow the Bi-Focal element to be formed on the inside layer of the lens, making it virtually undetectable from the front.
