[1] For polycarbonate & CR39 lenses across colors achieving 18% transmission at 23°C.
[2] For polycarbonate and CR39 lenses across colors. Blue-violet light ismeasured between 400nm and 455nm (ISO TR 20772:2018)
[3] Clear to extra dark photochromic category. Polycarbonate and 1.5 gray lenses tested at 35°C achieving <18%T using Transitions Optical's standard testing method
[4] Transitions® XTRActive® filters up to 45% of blue-violet light indoors and up to 86% of blue-violet light outdoors. Tests performed on gray lenses with a premium anti -reflective coating. Blue-violet light is between 400 and 455nm (ISO TR 20772:2018).
[5] Clear to extra dark photochromic category. Polycarbonate and 1.5 gray lenses tested at 23°C behind the windshield achieving between 18%T and 43%T.
[6] Based on tests across materials on gray 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."
[7] Transitions® XTRActive® Polarized filters up to 45% of blue-violet light indoors and up to 90% of blue-violet light outdoors. Tests performed on gray lenses with a premium antireflective coating.
[8] Based on tests across materials on gray lenses @ 23°C, using ISO 12312-1 standard.
