Business/Outdoor 2-Way Use: These lenses feature blue light filtering, essential for computer work, and photochromic technology that changes color when exposed to sunlight outdoors. Blue light cut rate JIS standard 40%: 40% cut lenses are suitable for desk workers and others who use PCs for long periods of time, as well as e-sports players, gamers, and those who use smartphones for extended periods. (A higher number doesn't necessarily mean better performance.) Frame design features: The half-rim frame (nylon rim) is designed to enhance business settings. It features a half-rim design where grooves are carved into the edge of the lens and the lens is secured with transparent nylon thread, ensuring a wide field of vision. Photochromic Color-Changing Function: Indoors, the clear lens tint is approximately 5%, almost transparent. (Due to the blue light cut coating, it appears slightly yellowish upon closer inspection.) Outdoors in bright sunlight, the tint changes to approximately 30%. This is not a tint so dark that you can't see (approximately 60%), but rather a change to light gray, a soft-colored sunglasses type that is currently trending and often seen worn by celebrities. (Also, a common misconception is that the lenses won't change color while driving, but most cars have UV-cutting coatings on their windows, so UV-chromic glasses won't change color. The color change only occurs in outdoor sunlight.) UV400 Coating: The UV400 protective coating blocks 99% of harmful UVA and UVB rays, protecting your eyes from UV damage.
