100% Photochromic lenses feature a reactive pigment inside that senses the intensity of the UV light around you; always evolving your lens tinting to match the light conditions. Rather than manually swapping lenses, choosing our Photochromic lenses allows a transformation from a Category 0 to a Category 2 tinted lens in less than fifteen seconds – all while never taking your eyes off the prize 👀 #100Percent #Photochromic #WeDeliverVision #Glasses #SeeMoreofWhatMatters
