Shilijia: Does looking at a mobile phone really affect your eyesight more than reading a book?

Many parents attribute the cause of their children's myopia to the use of electronic products, so I often hear parents scolding their children: stop playing with mobile phones, your eyes will be blind, go read a book! Does looking at your phone really affect your eyesight more than reading a book? In fact, whether it is looking at a mobile phone or reading a book, the eye's accommodation response is similar, which may increase the risk of myopia development. That is to say, at the same distance and time, viewing a mobile phone and reading a paper book The effects on children's vision are similar. Why do we think that looking at mobile phones is more prone to myopia? It is because compared with books, the screen of mobile phones has brighter colors and more interesting content. Most children will be more focused when playing with mobile phones, blink less, and use The eyes can't stop at all, which causes eye fatigue, easy to dry eyes, and more likely to lead to myopia. In addition, the screen of the mobile phone is smaller than that of the book, and the child will be closer when looking at the mobile phone. Shilijiaxiang reminds parents that preventing children's myopia is not just "don't let the phone play", but to control the time when the eyes are used at close range. 1. Pay attention to eye light and create a good eye environment. When children read and write, ensure that the brightness of the light is even and appropriate, and there is no dazzling glare. It is best to use a desk lamp with a light, and the light of the desk lamp should shine from the upper left corner, but not directly into the eyes. When a child is looking at a computer or electronic screen, the indoor light intensity is preferably about half of that when reading or writing. Also, try not to let the light source shine directly on the screen to reduce glare. 2. Develop good eye habits, follow the 20-20-20 principle when using electronic screen devices, follow the "20-20-20" principle when reading and writing, that is, turn your eyes to at least 20 feet away every 20 minutes (approximately 6 meters) for at least 20 seconds, allowing the eyes to relax and rest. It is best to leave the electronic screen or desk for at least 10 minutes every 40 minutes, move around, and avoid using your eyes at close range for a long time. 3. Ensure adequate outdoor activities and sleep time. Children should have time for outdoor activities every day, preferably more than two hours. Moderate ultraviolet radiation in sunlight can promote the body to produce more dopamine, and dopamine can effectively delay the growth of the eye axis; the outdoor light intensity is higher than that of the indoor, which makes the pupils shrink, the depth of field is deepened, the blur is reduced, and you can see clearly, Helps to delay the occurrence and development of myopia; outdoor viewing distance is far, many activities have far and near vision distance switching, which is helpful for eye relaxation. In addition, make sure you get enough sleep, do regular work and rest, and go to bed early and get up early.
