VLT

What is VLT?

VLT = Visible Light Transmission. It is the percentage of visible light that passes through the lens. A lower percentage gives a darker view; a higher percentage gives a brighter view.

VLT describes lens brightness. Check the lens specifications for this variant.

This lens provides UV400 protection. Lower VLT gives a darker view; it does not mean stronger UV protection. Photochromic lenses retain UV400 protection in both lighter and darker states.
