7 Compared to clear to extra dark photochromic lenses. Transitions XTRActive Polarized polycarbonate grey lenses filter 35% of harmful blue light indoors. “Harmful blue light” is calculated between 380nm and 460nm
8 Based on tests on polycarbonate grey lenses, up to 10% darker than the previous generation @ 23°C and up to 5% darker @ 35°C.
9 Based on tests across materials on grey lenses, achieving transmission below 45% @ 23°C behind a standard windshield. The lens achieves a polarisation efficiency of 30% behind the windshield, which is not classified as being “polarised”.
10 Based on tests across materials on grey lenses @ 23°C, using ISO 12312-1 standard.
11 Protection from harmful blue light (380nm-460nm) at 23°C among polycarbonate and 1.5 grey lenses in the clear to dark photochromic category
12 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 30% behind the windscreen, which is not classified as being “polarised”
