What is Blue light
Blue light refers to light with a wavelength of 380-495nm, which is a kind of visible light. The blue light has a short time and high energy. It can directly penetrate the lens to reach the fundus retina. This can cause damage to people's eyes and skin, cause eye fatigue, and may even cause age-related macular degeneration, which not only causes visual fatigue, but also is not conducive to normal sleep. Blue light is widely used in LED light source products such as personal computers, mobile phones, tablet computers, game consoles and TVs.
