Transition® Signature™ 7 adaptive lenses are the leading brand of photochromic lenses. Fully clear indoors – but outside, they’re more responsive than ever thanks to our exclusive Chromea7™ photochromic technology. They are more reactive to UV light so they get darker in more conditions, including bright sun, partially sunny, cloudy, and everything in between. They also adapt to indirect light – such as light reflected from buildings, cars, and many other surfaces. Transition® Signature™ 7 lenses are the latest generation of the classic, everyday, Transition® lenses. Lenses have no tint indoors, and darken to an 80% tint outdoors. Transition® Signature™ 7 do not darken inside a car. For more information, visit our Transitions lenses FAQs or the Transitions website.
