The Mask man Eyes Layer The One is a lens photochromic polarized with mirror multilayer. The category of the optical filter varies from S2 to S3 in response to light conditions.
In conditions of bad weather, the color yellow and the filter polarizing considerably increases the perception of contrasts, allowing to distinguish the shape of the snowpack.

In good weather conditions, the dark color makes the camera comfortable and the lens is very more beautiful from the outside, while the filter polarising eliminates reflections on the ground when you look at the light.
