*Compared to clear to dark photochromic lenses.
** Transitions XTRActive Polarized lenses filter up to 45% of blue-violet light indoors and up to 90% outdoors. Tests performed on grey lenses with a premium anti-reflective coating. Blue-violet light is between 400 and 455nm (ISO TR 20772:2018)
*** EcoOptics Limited – Prof. Nicholas Roberts, Quantitative study evaluating the visual benefits of the polarization properties of lenses, 2019/2020.
1. Based on tests across materials on grey lenses @ 23°C, using ISO 12312-1 standard.
2. Based on tests across materials on grey lenses, achieving transmission below 45% @ 23°C behind a standard windshield. The lens achieves a polarization efficiency of 30% behind the windshield, which is not classified as being “polarized”.
3. Filters up to 45% of blue violet light indoors. Test carried out on grey CR39 and polycarbonate lenses with a premium anti reflective coating. Blue violet light is between 400 and 455nm (ISO TR 20772:2018).
4. Based on tests on polycarbonate grey lenses, up to 10% darker than the previous generation @ 23°C and up to 5% darker @ 35°C.
5. Based on tests on polycarbonate grey lenses compared to the previous generation, fading back to 65% transmission @ 23°C.
