Life is dynamic, filled with constantly shifting light scenarios that challenge vision. In this dynamic reality that ranges from dim indoor lights to bright sunlight, traditional clear lenses struggle to meet daily visual demands.

With 9 out of 10 wearers interested in more than just vision correction from their lenses1*, Transitions® GEN S™ steps in as the new lens standard, going beyond the ordinary and offering a dynamic, fantastic and love-wear experience that aligns with the everchanging rhythm of life.


With Transitions GEN S, embrace light in harmony with your life.

  • Fadeback in less than two minutes²*
  • Up to two times faster to fade back³*
  • Only 25 seconds to sunglasses dark (cat 3)⁴*
  • The fastest dark lens⁵*


With Transitions GEN S, express yourself with endless pairing possibilities.

  • Widest range on the market: 8 vibrant colors
  • New addition to the portfolio: the Ruby color
  • Better color consistency at all stages
  • Endless pairing possibilities

Transitions GEN S is available in 8 exclusive colors, including a brand-new addition: Transitions GEN S Ruby. All colors have been optimized to be true to tone at all times, offering vibrant tints regardless of the light or environment.

While being fully clear indoors, and beautifully colored outdoors, Transitions GEN S provides endless possibilities of pairing to complement any look.


With Transitions GEN S, experience a better vision quality, faster.

  • 39% faster vision recovery from intense bright lights vs. clear lenses⁷*
  • 40% faster vision recovery during fadeback vs. previous generation⁸*
  • 39.5% improved contrast sensitivity during fadeback vs. previous generation⁸*

Our groundbreaking technology has been developed with one ambition in mind: uncompromised performance.

  • Proprietary & patented technolog
  • 30 years of photochromic expertise
  • 100,000 lenses tested
  • 1,500 new photochromic dyes created
  • 120 dedicated scientists

Transitions® GEN S™ uses advanced symbiotic technology where the dyes and matrix are specifically designed to seamlessly interact together. The new matrix architecture strikes the right balance between soft and hard spaces, facilitating dye performance while maintaining robustness. The new super-charged dyes absorb more energy, improving the kinetics inside the matrix and providing the right balance between vivid colors and seamless responsiveness.
