Children now have online classes every day. We can take the following measures to protect their eyes. First, move his chair back a little. Now, when they have online classes every day, their eyes are farther away from their mobile phones, which can prevent myopia. If they keep this distance for a long time, their eyes will get used to it and they can see far away. We should have a rest when we watch our mobile phones. Looking at it for a long time is not enough. After watching for a while, we have to rest the children's eyes. If you are watching the recorded video, you can pause and look out of the balcony. If it is a live broadcast, you can close your eyes halfway, take a short rest, do eye exercises for your ears to listen to, or take a notebook to write down ways to protect your eyes, so you won't forget when you watch it. Parents should also observe their children more and don't let his bad habits continue to appear. If you want to protect your child's eyes, it is also the most important to let him do eye exercises. Now the school advocates that this is effective and can only be done twice a day. Another way is to let the child rub his hands and then cover his eyes with his palm, which can promote the blood circulation of his eyes and protect his eyesight. Because of the epidemic, many places don't stipulate the start time, but parents are very concerned about their children's study and can only attend classes online at home, which will lead to their children's eyes getting closer and closer. If they don't protect their eyes, they will get closer and closer. If the child's eyes are very sour, you can look at the green plants properly, and watching the green plants can also alleviate the fatigue of the eyes. You can also do sports with your children in the house, because not only your eyes are tired, but also your body will be very tired. We can do sports with your child in the house, which can release his stress and relieve his fatigue. You must be in a very large space to avoid bumps, such as push-ups and sit-ups. That's good. You can also let your child listen to some favorite music, let him exercise, let him relax wholeheartedly, and his eyes will be relieved.
