Nowadays, electronic products have become indispensable in people's lives. I'm afraid to miss any "boss's instructions" when I brush my mobile phone at work, and I'm afraid to miss any "melon eating" opportunity when I brush my mobile phone at work. A recent study in the journal aging frontier shows that overexposure to the blue light emitted by the screens of electronic devices such as mobile phones and computers may be harmful to various cells of the body, including skin cells, fat cells and even neurons, and will accelerate aging. Blue light has shorter wavelength and higher energy than red and green light. In addition to accelerating aging, the harm of blue light to human eyes is also manifested in the harm of eye pathology and human rhythm resulting in myopia, cataract and maculopathy. In life, many people will suffer from visual fatigue after playing mobile phones for a long time. In the long run, it may lead to people's myopia deepening, diplopia, easy serialization during reading, and inability to concentrate, which will affect their learning and work efficiency. Now that the harm of blue light has been discovered, how can we reduce or avoid these injuries? First of all, we need to reduce the time spent looking at the screen, which is essential to "maintain youth forever"; Turning on the night mode of electronic equipment can reduce a certain amount of blue light hazards; Wearing glasses with amber yellow lenses can filter part of the blue light of the electronic display; Put electronic products away from yourself before going to bed, otherwise it will affect sleep and even lead to sleep disorders.
