What is a photochromic lens?
Let's start with the etymology of the word "photochromic" which comes from the Greek "photos" meaning light and "Chroma" meaning color. So, photochromic simply means changing color based on light . Compared to sunglasses, photochromic lenses darken or lighten depending on their exposure to ultraviolet (UV) rays. They are clear indoors and darken quickly in the sun outdoors when subjected to UV radiation and light.
Photochromic lenses adapt easily to your environment and protect your eyes from brightness and glare.

To know :
Photochromic lenses are not recommended for people who change environment often. Indeed, in general, they darken quickly outdoors but take longer to return to their initial state when there is less light, up to 5 min depending on the case.
