The UV 400 filter used in the glazing is guaranteed to protect the eyes from harmful ultraviolet radiation. It blocks 99.9% of wavelengths up to 400 nanometres, both UVA, UVB and UVC. The use of goggles with UV protection is a cornerstone that can prevent serious health problems.

Lenses with category S4 are designed for very bright light, and will work well on high glaciers where the sun[s rays reflect strongly off the surface of the snow. They absorb between 92 and 97% of the light and have a heavily shaded surface.

Temperature fluctuations can cause unwanted fogging on the inside of the lens. To prevent this effect from occurring, the lens is treated with a special coating that prevents fogging. This increases safety and comfort when on the slopes.
