First of all, a very important premise, are photochromic lenses suitable for your purpose and environment of wearing glasses? If it doesn't fit, the issue isn't much to discuss. Your use environment is not suitable for photochromic lenses, why do you buy them? Are the lenses really stupid?
Photochromic lenses have a history of more than 60 years. I believe they are older than most of the people who discuss this issue here. There must be something special about them that have existed for so long, otherwise they would have been eliminated long ago. Most photochromic lenses are UV-sensitive, that is, they change color in an environment with ultraviolet radiation, otherwise they will fade; a small part is infrared-sensitive, which is more sensitive.
The photochromic lenses is mainly designed for outdoor environments, which can effectively block ultraviolet rays and protect the eyes. It is definitely an eye-protecting tool for outdoor sportsmen.

Powerful photochromic lenses, the color change/fading will be completed within 1-3 minutes. For those who say that the color fades in 10 minutes, I can only say that you get what you pay for.

You are wearing color-changing glasses. What are you thinking?
