Description
The decrease of the protective effect of the ozone layer increases the importance to be well protected of the sun. Indeed, the eyes (and our skin) are very sensitive to high energy rays which exist in the ultraviolet (UV) spectre. even if the weather is cloud covered, the UV protection is essential because the clouds absorb visible light, but very little UV.
The eyes are even more exposed when we are in moutains or in environments where the UV are reflected by snow, water, sand, reverberation from clear walls, windows or mirrors (for example : water reflects 5 to 10% of UV rays; sand 20%; snow 85%). Furthermore, in moutains, the quantity of received UV raises by 10% every 1000 meters.
This is why all our safety glasses LUX OPTICAL filter 99,9% of UV rays.
