YIMI Photochromic Progressive Multifocus Reading Glasses UV Sun Readers Blue Light Blocking Lightweight Glasses for Men Women

Product description Photochromic Lenses-Lens become darker when light become brighter Photochromic Reading glasses Lenses are clear when indoors or at night and automatically darken to a sunglasses tint when exposed to UV sunlight. Lenses will begin to clear as soon as they are away from UV sunlight, and will be noticeably lighter and mostly clear within a few minutes. They absorb UV radiation that can otherwise damage your eyes. They are an excellent solution for people who hate constantly switching between their reading glasses and their shades. The lenses of photochromic glasses change tint depending on the weather or environment. The benefit of photochromic lenses is that they brighten up in dim, cloudy, or darker environments like running or biking through the woods or morning/evening. But in bright, sunny conditions, they dim. Photochromic lenses are most popular with cyclists, runners, skiers, tennis and outdoor reading enthusiasts. See More
