Photochromatic lenses are lenses that set off a reversible chemical reaction, causing them to darken when exposed to UV radiation or solar light in general.
Once the radiation disappears, the lenses gradually return to their original transparent colour.
Our photochromatic lenses are in polycarbonate, decentered, optically correct and filter 100% of UV rays.
The DEMON line includes three types of Photochromatic lenses. The factors that distinguish them are essentially the base colouring and the category of protection they can obtain:
»SMOKE: starts at Category 1 and darkens to almost reach Category 3.
»PINK: starts at Category 2 and darkens to reach Category 3.
»SMOKE 2-4: starts at Category 2 and arrives at Category 4, For high mountain.
