Photochromic Lenses look like regular clear lenses when indoors but automatically darken when moving into a brighter area. Ultraviolet (UV) rays from the sun affect the molecules in the photochromic lenses so they change colour. They will darken in the light even on overcast days as UV rays still penetrate clouds. The color od the lenses adapt to the brightness, without you need to think about it. The SPECTRUM 37 lenses go from CAT2 to CAT3 in just 8 seconds, a real record!
