Transitions® GEN S™ is the fastest dark lens in the clear to dark photochromic category. It is fully clear indoors and darkens in seconds outdoors. It is ultra-responsive to light, reaching category three levels of darkness in 25 seconds and fading back in less than two minutes. It also has improved long-lasting performance over time.

Transitions^® GEN S^™ is available in eight exclusive colors, including a brand-new addition: Transitions^® GEN S^™ Ruby. All colors have been optimised to be true to tone at all times, offering vibrant tints regardless of the light environment. While being fully clear indoors, and beautifully colored outdoors, Transitions^® GEN S^™ provides endless possibilities of pairing to complement any look.
