Many people think that children are facing mobile phones and computers all day, which is the bane of myopia. Actually, it's really a bit of a burden!
You know, our eyes focus on what we see through the adjustment of lenses. The adjustment of the lens is achieved through the ciliary muscle. If you are nearsighted for a long time and the ciliary muscles are tense for a long time, then after a long time, you can no longer adjust the lens to focus on distant objects.
Ciliary muscle is also a kind of muscle, which can enhance and restore vision through exercise. This is pseudomyopia. True myopia is equivalent to muscle atrophy, and there is no ability to contract and relax.
Then, the most important reason for children's large-scale myopia is obviously not mobile phones and computers, otherwise there should be no myopia in the era without mobile phones and computers. One of the most critical reasons is that this era allows us to stay indoors and solve the most basic survival problems.
Don't blame the child for staring at the mobile phone. Feel your heart. You haven't gone out for a walk with the children for a long time. How long has it been since you went to the park to play football with your children? In addition, children are now burdened with various learning tasks. Besides school homework, I also have various interests, such as art, Go, piano and Lego. Parents feel that even an hour of leisure is a sin for the future.
Experts say that at least three hours of outdoor exercise every day can ensure that the eyes get enough rest, that is, the ciliary muscles get enough exercise to effectively resist the influence of long-term close-up viewing. However, such three hours of outdoor time is too extravagant for children. Therefore, myopia can be said to be a disease that grows up with the lifestyle of modern society, and it may become a normal state in the future. In fact, the prevention method is also very simple. As long as you have enough courage to put down your mobile phone and look at the blue sky, can you do it?
