Students usually bend their heads and concentrate on reading for too long, and they are most likely to be nearsighted. In this case, we can consider combining work and rest. After working and studying for an hour, consider taking a rest for about 5 minutes. You can ignore it, or you can buy eye drops directly to prevent visual fatigue as an aid. You can also do the previous eye exercises and press your own eye acupoints to relax. As long as you are tired, you like to do eye exercises, or the eye exercises put in between classes when you were a child are the most useful.
