VLT (Visual Light Transmission) is a measure of the amount of white (visible) light that can pass through a lens and be detected by the eye.
We want to provide the optimum optical clarity whilst always providing the highest level of protection possible, therefore the lowest VLT SunGod offer is 11% which counts as a Category 3 lens. All lenses offer 100% UVA and UVB protection.
Lower VLT percentages are illegal to drive in in many countries and for this reason we do not offer Category 4 lenses.
You can check the VLT of every lens SunGod offer using our Lens Preview tool underneath the product designer, please follow the links below to have a look!
