Based on tests across materials on grey lenses @ 23°C, using ISO 12312-1 standard.
Based on tests on polycarbonate grey lenses, up to 10% darker than the previous generation @ 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 windshield. The lens achieves a polarization efficiency of 30% behind the windshield, which is not classified as being “polarized”.
Blocks 34% of harmful blue light indoors. Protection from harmful blue light (380nm-460nm) at 23°C among polycarbonate and 1.5 grey lenses in the clear to extra dark photochromic category.
Based on tests across materials on grey lenses @ 23°C. “Harmful blue light” is calculated between 380nm and 460nm.
Up to 2x faster to fade back. Based on tests on polycarbonate grey lenses compared to the previous generation, fading back to 65% transmission @ 23°C.
Block up to 34% of harmful blue light indoors. "Harmful blue light” is calculated between 380nm and 460nm.
Tested on grey lenses across materials at 23°C outdoors achieving using Transitions Optical's standard testing method.
