VLT - Visible Light Transmission
VLT is a measurement that specifies the percentage of light coming through the lens and reaching your eyes. A totally clear lens for dark conditions typically have around 90% VLT and a very dark colored lens with mirror for sunny conditions may have down to 10% VLT. Most all round lenses will be found between 30 to 60%.
THRAMA® LENS TECHNOLOGY
The Thrama® system is based on the fundamental concept of transmittance, that is on light selection filtering techniques aimed at drastically reducing visual “noise” (diffused light) and intensifying the “signal” in order to optimize visual information. The Thrama® system can filter the first three primary colors in the visible light spectrum (blue –green-red, wave-length of 400 to 700 mm) in different percentages, thus increasing the chromatic contrast and optimizing the image perception in the fundamental visual receptors present in the central retina. Furthermore, it ensures total protection from UV rays thanks to special additives that can neutralize UVA and UVB rays up to the threshold of visibility (400 mm).
NASTEK® LENS TECHNOLOGY
Nastek lenses are the most advanced and cutting edge blue light reducing lenses. Protects the eyes from blue light damage and enhances vision contrasts.
Surface treatment that prevents the lenses from misting up, thus preventing visibility problems in critical conditions.
Plating of metallic particles on the surface of the lens that softens excess light.
