Lens tinting and categories

If you have ever bought a pair of cycling glasses, you will certainly have heard the term “lens tint” before. This defines the color of the lenses and also how strongly or weakly the glasses darken surrounding light. So that you know exactly which tint is right for you, different categories are given for the lenses of sports glasses.

Sports glasses VLT value

But how exactly do these lens categories come about? This depends on the so-called VLT index (Visible Light Transmission Index). This describes how much visible light can shine through a lens and is not blocked. A VLT value of 100% means that 100% of all visible light rays pass through the lens. The lower the VLT value, the darker the lens and the more visible light is blocked. To make this easier when buying, sports lenses are divided into corresponding categories. The following table provides a simple overview of the areas of application of the lenses:
