CATEGORIES:

 

Category 4lenses are the strongest of all, they can filter up to 97% of sunlight. They are only used in situations of extreme sunlight, for example for mountaineering on glaciers or on high mountains where the sunlight is increased tenfold due to reflections on ice and snow. The S4 sun filtration index is forbidden when driving as it alters vision and perception of colours.

 

Category 3 solar lenses provide a perfect filter for most light conditions. Your solar lenses will filter 83 to 92% of sunlight. They offer excellent eye protection from sun rays and glare for most of your activities. This protection is particularly effective in conditions of strong sunlight (during summer, holidays by the sea, on the beach and winter sports).

 

Category 2 solar lenses will filter out 58% to 82% of ambient sunlight. This protection is effective in medium sunlight conditions. Category 2 lenses can be worn in periods of variable sunlight and between seasons, for example at the beginning of spring and the end of autumn.

 

LENS COATING:

 

More than a simple coating, photochromic technology is embedded within the molecular structure of the lens. Therefore, your lenses will lighten and darken instantly depending of the light conditions, protecting your eyes from harmful UV rays.
