Category :

The category of a lens depends on the amount of light (visible light transmission rate) that passes through it.

Category 0 has an 80-100% transmission rate and is used for comfort.
Category 1 has a transmission rate of 43-80% and is used for low light.
Category 2 has a transmission rate of 18 to 43% and is used for medium brightness.
Category 3 has a transmission rate of 8 to 18% and is used for strong light.
Category 4 has a transmission aux of 3 to 8% and is used for exceptional brightness.

Choose your category of protection carefully:

Two elements of the mask contribute to the protection of your eyes: the protection index against UV radiation and the tint of the lens against glare. In the mountains, the rays are less filtered by the atmosphere. The masks are divided into 4 categories of “protection”:

Category 1: for riding in very low light or in bad weather,
Category 2: for riding with low sunshine (alternating sun and cloudy periods, uncertain weather),
Category 3: for riding mainly in sunny weather (the most recommended),
Category 4: for riding in intense light, especially in the high mountains.
