Transitions® lenses

Transitions® lenses change from clear to dark in different light conditions, they will darken when activated by UV light and return to clear indoors when you are no longer exposed to the UV light. They are available in Grey or Brown with the following index options; Standard 1.5 Index, Thin & Light 1.6 Index and Thinner & Lighter 1.67 Index lenses. We have added some video to show how the lenses change in different light conditions.
