Blue-light-proof membrane technology is very mature and low cost, which can effectively prevent blue light from penetrating. It is especially pointed out here that blue light is not all harmful blue light, but really harmful blue light within 440 ~ 470nm, while blue light between 480 ~ 500nm has the function of regulating biological rhythm, which is related to sleep, mood and memory and is beneficial to human body.

Moreover, whether short-wave blue light will definitely cause harm to human eyes is related to irradiation intensity and irradiation time. When the light reaches a certain level and lasts for more than two hours, it may cause damage to the retina. ?
