REONAS Blue Light Blocking Glasses for PC and Outdoor Transforms into Sunglasses for Outdoor UV400 Aluminum Magnesium Arms Photochromic,

[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 combination of a slightly streamlined frame (rim) and aluminum magnesium arms (temples) creates a unique design. [Blue light blocking rate: 40% as per JIS standard] The 40% blocking lenses have a blocking rate suitable for desk workers and other people who use PCs for long periods of time at work, as well as e-sports players, gamers, and people who use smartphones for long periods of time. [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.) [UV400 Coating] UV400 protective coating blocks 99% of harmful UVA & UVB rays, protecting your eyes from UV damage.
