Photochromatic lenses start with light grey lenses that darken automatically in dark grey when exposed to UV light, and adapt to the brightness. The polarization of the lenses eliminates unpleasant reflections, improves the quality of vision and reduces eye strain. They are therefore the solution for those who want to combine comfort with a reduction of visual fatigue and glare in the sun. In addition, having a single pair of glasses for indoor and outdoor use offers a real advantage! Protection cat. 2 to 3.
