REONAS Sports Blue Light Transforms into Sunglasses for PC Work and UV400 for eSports and Sports Watching Glasses, Photochromic, Color-Changing,

[Two-way use for business/outdoors] Equipped with two-way lenses that cut blue light, which is essential for working on a computer, and a dimming function that changes color when exposed to sunlight when you're out and about. [Frame design features] The sporty frame and adjustable modern (front cell) specifications enhance individuality. Sports/eSports/Road bike [Photochromic and Color-Changing Function] The lenses are clear and colorless indoors. When outdoors on sunny days, they will change color to about 30% of their original density. This is not so dark that you can't see (about 60%), but rather a light gray discoloration, similar to the soft-tinted sunglasses trend often seen worn by celebrities. (Also, a common misconception is that the lenses won't change color while driving, but since most cars have UV-blocking coating on the windows, UV-photochromic glasses won't change color. This only happens outdoors in sunlight.) [Blue light blocking rate: 40% as per JIS standard] The 40% blocking lenses have a blocking rate suitable for desk workers who use PCs for long periods of time at work, as well as e-sports players, gamers, and those who use smartphones for long periods of time. [UV400 Coating] UV400 protective coating blocks 99% of harmful UVA & UVB rays, protecting your eyes from UV damage.

[Frame Design Features] The sporty frame and adjustable temple tips (tip cell) enhance your individuality. Sports/Esports/Road Biking [Photochromic/Color-Changing Function] These lenses are colorless and transparent indoors. When outdoors on sunny days, they change color to approximately 30% of their original density. This does not darken the lenses to the point of blinding (approximately 60%), but rather to a light gray, a soft-color sunglasses-type color change that is currently trending and often seen on celebrities. (Some people also mistakenly believe that glasses will not discolor while driving, but most cars have UV-blocking coating on the windows, so UV-adjustable glasses will not discolor. They will only discolor outdoors in sunlight.)
