Lens Tint Categories

It is important to understand that the colour of a lens can have an effect on the user depending on the amount light transmittance. There are European Australian and American standards which generally use a 5 point category system to identify the different lens colours.

The sunglasses we sell are all 100% UV protection lenses in categories 0 through to 3 we do not sell category 4 sunglasses. If you are not sure of the lens category of any of our sunglasses please contact us and we will gladly help.

Category 0

Category 1
This is a lightly tinted lens with 50% to 80% light transmittance for cosmetic or fashion use in low or weak sunlight conditions not recommended for night time driving

Category 2
This is a medium tinted lens with 25% to 50% light transmittance for general use in medium sunlight conditions not recommended for night time driving
