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

1 93% want or are interested in lenses that enhance their vision beyond vision correction. Transitions Optical, Consumer study on the link between Vision & Protection, external research agency, (CAWI), U.S., Q4 2021, N= 1,000.

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

3 For gray polycarbonate & CR39 lenses fading back to 70% transmission @ 23°C, compared to the previous generation.

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

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

6 For gray polycarbonate lenses, compared to the previous generation.

7 Compared to clear lenses. 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, photo-stress recovery) with the clear and darkest states of Transitions GEN S Gray 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.

8 Compared to the previous generation. 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 fadeback with Transitions GENS Gray1.6 index lenses with a premium anti-reflective coating compared to Transitions Signature GEN 8 Gray 1.6 index lenses with a premium anti-reflective coating. Principal investigator Prof Pablo Artal. Accepted abstract at ARVO 2024. Duarte-Toledo R, Mompeán J et al., A new photochromic lens improves contrast sensitivity during fadeback.

9 Vision quality improved in challenging light conditions, notably in bright to very bright light situations. Compared to clear lenses. Subject-masked cross-over randomized controlled investigation performed in 2023 on 30 healthy participants (19.2±1.3years). Testing light stress (discomfort and disability glare, photo-stress recovery) with the clear and darkest states of Transitions GEN S Gray 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. Vision quality improved in challenging light conditions, notably when moving from a bright to a darker environment. Compared to the previous generation. 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 fadeback with Transitions GEN S Gray 1.6 index lenses with a premium anti-reflective coating compared to Transitions Signature GEN8 Gray1.6 index lenses with a premium anti-reflective coating. Principal investigator Prof Pablo Artal. Accepted abstract at ARVO2024. Duarte-Toledo R, Mompeán J et al., A new photochromic lens improves contrast sensitivity during fadeback.

10 After seven days of trail per lens type, 86% of wearers chose to keep Transitions GEN S, 5% of wearers chose to keep Transitions Signature GEN 8, and 9% of wearers chose to keep the premium clear lenses. Source: Wearers Test conducted by an external market research agency in the U.S. in Q1 2023 with 134 prescription lens wearers wearing 1.67 index lenses with a premium anti-reflective coating in clear, Transitions GEN S Gray and Transitions Signature GEN 8 Gray.
