Frequently Asked Questions

What are Transitions® lenses?

Transitions® lenses are the #1 eyecare professional-recommended photochromic lenses worldwide. Transitions® lenses are equipped with patented, photochromic dyes that enable the lenses to rapidly darken, when they are exposed to ultraviolet light. The greater the intensity of UV rays, the darker the lenses become. When UV light is no longer present (indoors or at night) the lenses fade back to their original state.

Are Transitions® lenses as clear as an ordinary clear lens indoors?

Yes, Transitions® Signature® GEN 8™ lenses are completely clear indoors

How do Transitions® lenses differ from prescription sunglasses?

Sunglasses have a set tint - no matter what situation you’re in they’re always the same shade. Unlike sunglasses, Transitions® lenses start as clear lenses and then automatically darken accordingly to the level of UV light present. They continuously and smoothly adapt their level of tint so that you see well in all light conditions.

Do Transitions® lenses work in all frames?

Yes, Transitions® lenses work in most frames.

1. Transitions® lenses filter at least 26% of blue-violet light indoors & at least 86% outdoors. Tests performed on grey lenses with a premium anti-reflective coating. Blue-violet light is between 400 and 455nm (ISO TR20772:2018)
2. *Based on measurements performed by an external laboratory in the USA between 2015 and 2019 of photochromic performance
attributes. The attributes were also weighted by their relative importance to consumers based on 1,037 responses to a research survey
conducted by SSI (Survey Sampling International) of US.
3. The darkest in hot temperatures & in the car, blocking 100% UVA & UVB and offering the best overall blue-violet light filtration across light situations* among clear to extra dark photochromic lenses.*Filtering blue-violet light(between 400 and 455nm ISO TR20772:2018) among polycarbonate and CR39 grey lenses with a premium anti-reflective coating: filtering (i) up to 45% indoors at 23°C, (ii) up to 64% behind the windshield (iii) up to 86% outdoors at 23°C and (iv) up to 83% outdoors at 35°C. .
