Photochromic lens
Plastic photochromic lenses use organic photochromic molecules (for example oxazines and naphthopyrans) to achieve the reversible darkening effect. Photochromic lenses filter 100% UVA as well as UVB. wikipedia.org

Cycling glasses life span I've had my Tifosi sport glasses with photochromic lenses for about 4 years. Lately, when I rode them in 10 am morning sun, my eyebrow and eye started to feel terrible pain, that passed once ...
The photochromic layer itself is activated by UV light but is also damaged by it. Generally, one can expect photochromic lenses to last 1-3 years depending on use.

Diarylethene
This means that their isomerization in a solid matrix can take place much more quickly than with most other photochromic molecules. Therefore, many diarylethenes have photochromic behavior both in solution and in solid state. wikipedia.org
