Do blue light blocking glasses work? In today's era of rapid development of science and technology, it is no longer possible to leave computers, laptops, tablets and other digital products, you can work, live and play without leaving home, all of which are displayed through the Internet and computer displays. While improving your productivity and enjoying your entertainment life, your eyes are being damaged by blue light. Let's introduce to my myopic friends: anti-blue light glasses. What is Blu-ray? Blue light is an important part of visible light, there is no separate white light in nature, and blue light is mixed with green light and yellow light to present white light. Green light and yellow light have less energy, less stimulation to the eyes, short blue light waves, high energy, can stimulate an abnormal retinaldehyde in the retina, produce a large number of free radical ions, these free radical ions increase the damage effect of retinal aldehyde to the retinal pigment epithelium, thereby causing the atrophy of the retinal pigment epithelium, and then causing the death of light-sensitive cells, which will lead to gradual decline or even complete loss of vision. Sources of blue light: computers, mobile phones, bath bombs, projectors, laser pointers, fluorescent lights, LED flashlights, etc., all have a certain amount of blue light, which has a certain impact on vision, such as staring at mobile phones or computers for a long time, and the eyes will feel dry, tired, sore, and so on. However, it must be noted that blue light is only one of the factors that cause these problems, in addition to electromagnetic radiation, the screen itself flickering, and the eyes do not pay attention to rest for a long time. Do blue light blocking glasses work? Blue light is one of the factors affecting eye fatigue, and anti-blue light glasses can play a certain role in protecting the eyes, especially for people who stare at electronic screens for a long time. However, when choosing anti-blue light lenses, it must be noted that glasses must have an authoritative detection mark, and the blocking rate of glasses for blue light is more than 97% to be effective, and experiments have proved that if the blocking rate is less than 97%, the effect of protecting the eyes is not obvious. At present, Germany is relatively advanced in terms of blue light glasses technology. Small
