Transitions FAQ
What makes Transitions® Gen S™ different from other Transitions lenses?
Transitions Gen S lenses are formulated to be ultra responsive to light and in most conditions will darken in seconds outdoors and return to clear indoors very rapidly (around 2 minutes). Please note that temperature can affect the speed of these chemical changes within the lens, with optimal change occurring at 23ºC.
Gen S lenses are also the first to feature the new vibrant Ruby Red lens color option, along with seven other stylish lens color choices, all of which return to clear indoors.
