Occasionally, people forget to bring sunglasses with them when they go outside in their prescription glasses. It’s a common mistake. Well, photochromic lenses could be the solution you’re looking for. They automatically change from light to dark when they move from indoors to outdoors, so you never have to worry about forgetting them.
What are photochromic lenses and how do they work?
A photochromic lens, also known as a transition lens, is a type of lens that adjusts to changing light conditions, remaining clear indoors and darkening outdoors as necessary. While they are fully clear inside, they function as fashionable sunglasses as well as fully clear glasses inside when you are exposed to bright sunlight. In addition, they block 100% of UVA/B rays.
How do photochromic lenses work?
During the process of making a photochromic lens, small molecules are fixed into the lenses. The lenses are totally clear until they are exposed to sunlight. As a result of this chemical process, the molecules shift, change shapes, and absorb light. The molecules darken to the tint of a sunglass. During UV exposure, the photochromic lenses will remain dark while exposed to the rays, but when they are removed from the light source, the molecules will turn the lens back into its original clear state.
