The visible light seen in life is actually composed of visible light such as red, yellow and blue. The blue light band is 380-500nm. In this band, 4 15-455nm blue light has high energy and strong penetration. It can even penetrate the cornea and lens and reach the macular area of the eye, leading to macular degeneration.
Anti-blue lens mainly reflects harmful blue light by coating the lens surface (anti-blue film) to protect eyes. Now there is a new technology, that is, "substrate absorption+thin film reflection" double-effect blue light prevention. In addition to the blue light reflected by the film, the lens itself has added special ingredients to absorb the blue light and prevent it at the same time.
After reducing blue light, the eyes will not be tired because of too much harmful blue light stimulation.
