What are Photochromic Lenses?

Photochromic lenses, also known as photochromatic lenses, are a type of glasses lens that change colour depending on the amount of UV light they are exposed to. In bright sunlight, these lenses will darken to protect your eyes, but when you go inside or the UV light decreases, they'll turn back to clear, allowing you to see normally. This means you only need one pair of glasses for both indoor and outdoor activities, making it super convenient.
