What makes transition lenses darken?

When the UV light diminishes, the lenses fade back. As light conditions change, the level of tint adjusts, offering the right tint at the right time.
Do transition lenses wear out?
Transition lenses generally last the life of a pair of glasses (or longer), though they do wear out after years of use. Most Transition lenses wear out in about three years, with a yellowish tinge forming in the lenses while clear and a noticeable reduction of the lenses’ darkness in full sunlight.
