VLT (Visible Light Transmission) 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 50-90% VLT and a very dark colored lens with mirror for sunny conditions may have down to 20% VLT. Most allround lenses will be found between 20 to 50 %. In our range you will find alternatives for all kinds of conditions.
