- Clear to extra dark photochromic category. Tests across polycarbonate and 1.5 grey lenses using Transitions Optical’s standard testing method. Outdoors at 35°C achieves <18%T. Behind the windscreen at 23°C achieves between 18%T and 43%T. Fade back compared to the previous Transitions XTRActive generation across materials tested on grey lenses fading back to 70% transmission at 23°C.
- Based on tests on polycarbonate grey lenses; up to 10% darker than Transitions Vantage @ 23°C and up to 5% darker @ 35°C.
- Based on tests across materials on grey lenses, achieving transmission below 45% @ 23°C behind a standard windscreen. The lens achieves a polarisation efficiency of up to 30% behind the windscreen.
- Based on tests across materials on grey lenses @ 23°C, using ISO 12312-1 standard.
- Compared to other products in the Transitions portfolio. Based on tests across materials on grey lenses @ 23°C. ‘blue light’ is calculated between 380nm and 460nm.
- Based on tests across materials on grey lenses @ 23°C, using ISO 12312-1 standard tests across materials on grey lenses @ 23°C.

- Compared to other products in the Transitions portfolio. Blue light indoors (380nm-460nm) measured at 23°C, behind the windscreen, outdoors at 23°C and 35°C among polycarbonate and 1.5 grey lenses in the clear to extra dark photochromic category.
- Transitions Optical, Quality of Vision and Vision Experience Test In Real Life situations (Life Wearer Testing), France, Eurosyn, Q3 2020, N=148 – Top4Boxes*Based on wearers who preferred XTRActive II lenses (32% of total wearers). Cautious: small base size (n=46 wearers who preferred XTRActive II lenses).
- Helps reduce glare from harsh artificial lighting, digital devices and screens.
