Photochromic shields will turn dark in sunlight and become clear(or almost entirely clear) again when indoors. This is the result of chemical responses to the presence (and absence) of ultraviolet light.

Photochromic performance is influenced by temperature, UV exposure and riding posture. PLEASE NOTE!
Photochromic shields darken faster than they lighten, with the process being somewhat influenced by temperature. On a very sunny day, they can achieve maximum darkness in approximately 20 seconds. Full activation occurs in 2 minutes.
