Transitions GEN S Lenses Officially Available in the U.S.


PINELLAS PARK, Fla. — Transitions Optical announced that its latest iteration of lenses, the Transitions GEN S, are officially available in the United States. Through randomized controlled clinical trials, some of the world’s leading independent vision experts have demonstrated that Transitions GEN S provides better vision quality, faster.1

“People want more from their eyeglasses than just correction, and Transitions GEN S delivers, going above and beyond their expectations,” said Rose Harris, senior marketing director, Transitions Optical North America. “Our research and development team created a revolutionary lens that is not only intuitive and smart but allows for an elevated experience of complete pairing opportunities through an expanded color palette that enables wearers to personalize their looks with vibrant colors to match any frame.”

Revealed in February at Transitions Academy in Orlando, Florida, Transitions GEN S has already been receiving spectacular feedback from wearers. “… they are quick. That speed to me is unlike anything I’ve ever seen before,” commented one wearer.

“Patients deserve the best vision care we can offer, and light management is key. To achieve its mission, Transitions Optical offers a solution for comprehensive vision that goes beyond traditional correction. We have a real opportunity to improve patients’ vision care with Transitions GEN S lenses. We call it HD vision at the speed of your life: see well in all light conditions, dynamic, intuitive, and adaptive, with better vision quality, faster.1 It is set to become a key recommendation for eye care professionals,” said Harris. “Why prescribe a traditional, static lens when wearers can have Transitions GEN S ultra-dynamic lenses that fit their lifestyle?”

Transitions GEN S delivers with a unique vision: to embrace the synergy of speed, darkness, and color without sacrificing other performance aspects.

  • GEN SPEED: Ultra-responsive to light. Transitions GEN S is the fastest dark lens2* in the clear to dark photochromic category. It is fully clear indoors and darkens in seconds3 outdoors. It is ultra-responsive to light, reaching category three levels of darkness in 25 seconds4* and fading back in less than two minutes.5* In fact, when asked, 88% of wearers agreed that Transitions GEN S lenses adapted so fast to light that they didn’t or barely noticed the change.6* 
  • GEN STYLE: Spectacular color palette. Transitions GEN S is available in eight exclusive colors, including a brand-new addition: Transitions GEN S ruby. All colors have been optimized to be true to tone at all stages, offering vibrant tints in any light. While being fully clear indoors, and beautifully colored outdoors, Transitions GEN S provides endless possibilities of pairing to complement any look.  
  • GEN SMART: HD vision at the speed of your life. Transitions GEN S offers better vision quality to ensure a continuous visual experience7A* versus clear lenses. During fade back, tests have shown a 39.5% improvement in contrast sensitivity7B* and 40% faster vision recovery 7B* versus the previous generation. Moreover, Transitions GEN S provides ultimate light protection, darkening outdoors, blocking 100 percent UVA & UVB rays, and filtering up to 32% of blue violet light in the clear state and up to 85 percent when activated.8

 *Tests carried out on gray lenses. Photochromic performance may vary across colors and lens materials and is influenced by temperature and UV exposure.  

1. Vision quality improved in challenging light conditions, notably when moving from a bright to a darker environment (source B, Transitions GEN S compared to Transitions Signature GEN 8), in bright to very bright light situations (source A, Transitions GEN S compared to clear lenses) and in low light with peaky stray light (source A, Transitions GEN S compared to clear lenses). 

2. For gray lenses in the clear to dark (category 3) photochromic category. Transitions GEN S lenses fade back faster to 70% transmission while achieving less than 14% transmission when activated at @ 23°C.    

3. For polycarbonate & CR39 lenses across colors achieving 18% transmission at 23°C. 

4. For gray polycarbonate & CR39 lenses achieving 18% transmission @ 23°C.   

5. For gray polycarbonate & CR39 lenses with a premium anti-reflective coating fading back to 70% transmission @ 23°C.

7. A: Subject-masked cross-over randomized controlled investigation performed in 2023 on 30 healthy participants (19.2 ± 1.3 years). Testing light stress (discomfort and disability glare, photostress recovery) with the clear and darkest states of gray Transitions GEN S 1.6 index lenses with a premium anti-reflective coating compared to clear 1.6 index lenses with a premium anti-reflective coating. Principal Investigator Prof Billy R. Hammond. 

7. B: Subject-masked cross-over randomized controlled investigation performed in 2023 on 10 healthy pre-trained participants (29.5 ± 4.0 years). Testing contrast sensitivity during fade back with gray Transitions GEN S 1.6 index lenses with a premium anti reflective coating compared to gray Transitions Signature GEN 8 1.6 index lenses with a premium anti reflective coating.
