REONAS Blue Light Blocking Glasses with Photochromic and Technology for Transforms Into Sunglasses for Business or Outdoor Over UV Brand 2

[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. [Blue light blocking rate: 40% (JIS standard)] 40% blocking lenses are suitable for desk workers who use PCs for long periods of time at work, as well as those who play e-sports, game, or use smartphones for long periods of time. (A higher number does not necessarily mean better.) [Frame design features] The half-rim frame (wire frame) that creates a business look has a groove carved into the edge of the lens and the lens is secured in place with transparent nylon thread, ensuring a wide field of view. [Photochromic and Color-Changing Function] Indoors, the clear lenses appear almost transparent at about 5% color density (they have a blue light blocking coating, so they appear yellowish upon closer inspection). When outdoors on sunny days, the lenses will change color to about 30% color density. This is not so dark that you can't see (about 60%), but rather a light gray color change, similar to the soft-color sunglasses trend often seen worn by celebrities. (Also, a common misconception is that the lenses won't change color while driving, but since most car windows are UV-blocking, 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.

[Photochromic and Color-Changing Function] Indoors, the clear lenses appear almost transparent at approximately 5% light intensity (although they have a yellowish tint due to the blue light blocking treatment). When outdoors on sunny days, the color changes to approximately 30% light intensity. This is not a dark color that makes it impossible to see (about 60%), but a light gray discoloration, a soft color sunglasses type discoloration that is currently trending and often seen worn by celebrities. The main benefit is that the glasses will not discolor while driving. However, since most car windows are UV-blocking, UV-adjustable glasses will not discolor. Discoloration only occurs outdoors in sunlight. [UV400 Coating] UV400 protective coating blocks 99% of harmful UVA and UVB rays, protecting your eyes from UV damage.
