Do SunSensors lenses perform behind the windshield of a closed vehicle?
Fact is, no plastic photochromic lens performs well behind the windshield of a car. The windshield blocks UV light needed to activate the lenses. However, Corning Thin & Dark glass photochromic lenses react to both UV and visible light and will darken to a gray 2 behind a car windshield. • How do the photochromic properties of SunSensors lenses perform over time? The photochromic performance of SunSensors lenses will easily last the lifetime of an average prescription, satisfying your patients and giving you peace of mind. All plastic photochromic lenses will gradually lose their darkening and lightening ability due to UV exposure. Because the photochromic molecules of in-mass lenses are throughout the material when UV degrades some, the others step up to replace those lost. Creating a longer-lasting, more consistent color lens. Our testing shows in the clear state, after extended exposure, SunSensors lenses continue to maintain clarity. In its darkened state, a SunSensors lens that is
