Avoid using eyes for a long time. Many people like to play online games, and many people like to watch TV plays or movies on the computer. Some people are working. A lot of myopia is eye fatigue caused by excessive use of eyes, and the lens has lost its adjustment function. So myopia came into being. So the first step is to avoid using your eyes for a long time. Close your eyes every hour and let it have a full rest.
2. Pay attention to eye exercises.
Many people only do eye exercises in primary school, right? I still remember when the radio rang when I was a child, we would obediently follow the teacher to press our temples and scrape our eyes. In fact, this is an effective way to prevent attention and further relax our eyes. Avoid excessive fatigue. Just as the body needs to do broadcast gymnastics, the eyes also need eye exercises to protect them.
3. Look into the distance.
Look into the distance. With the development of science and technology, mobile phones and computers are becoming more and more popular. The farthest place that more and more people look at every day is the line sign on the bus in the distance. As a result, our lens can not be fully stretched for a long time and lose its accommodation function. When the weather is fine, we should stand on high places more often. It doesn't matter if we can't stand on the mountain or upstairs. We should look farther.

Other preventive measures
1, the light should be sufficient and comfortable.
Whether working or studying, we should work in a comfortable and well-lit environment. Too bright or too dark light is bad for eyesight, too dark is easy to cause visual fatigue, and too bright will irritate eyes.
2. Pay attention to reflection.
Many people think that bright light is enough. In fact, in addition to strong light, there is another problem that needs attention, and that is reflection. Working or studying under the reflection for a long time will be harmful to your eyes.
3, adjust the computer position
Nowadays, many people use computers. I don't know that the distance between the computer and the human body is also required. The distance between the screen and the eyes is 50-60 cm. Too long or too short a distance is harmful to eyes. The screen should be slightly tilted to avoid looking directly at the computer.
