Photochromic lenses are lenses that tint according to the natural light outside. They can darken or lighten rapidly depending on the degree of ultraviolet light to which they are exposed. Outside, the maximum tint of the lenses can vary according to the temperature.
The glasses can be worn indoors or outdoors and protect your eyes from UVA and UVB rays, invisible but present, even with very little sun, and from glare, giving you exceptional visual comfort.
The photochromic coating can be applied with all corrections. It is available with our single vision and progressive lenses. The photochromic lens, like tinted lenses, is not compatible with extra thin lenses. (index : 1.74)
