Automatic anti-blue light lens = filter blue light + change color in the sun. The real shot: The clip is a test of the light filtering efficiency of the Blve Auto lens. It can be found that the degree of ultraviolet light filtering of the lens is 400 nanometers (equivalent to sunscreen lenses). It can filter the blue light emitted by computers/mobile phones very well. Blue lasers cannot pass through the lens. Comparing ordinary lenses and blue lenses, it can be seen that if it is an ordinary lens, the light can still pass through the lens, but the blue lens cannot pass through the lens. (The light only affects the surface of the lens and does not penetrate below), and the lens will automatically adjust to black when it encounters light. Therefore, the area of ​​the lens exposed to the laser passes through the lens. Therefore, it will automatically darken, which is normal for automatic lenses.

Notes

1. All types of automatic lenses will not be as clear as ordinary lenses when exposed to the tree. This is because the lens material is mixed with color-changing substances. Therefore, if it is under light, the color-changing agent will automatically work. Help automatically filter light (so the lens will not be very clear) unless in low light conditions. Or at night, the lens will be as clear as usual.
