Nowadays, many people are myopic, has China been a high incidence area of myopia since ancient times

It's not that China has been a high-risk area for myopia since ancient times, butBecause the Chinese population is increasing, the number of people will increase several times compared to other countries, so our population is so large that the percentage of myopia must be high. The foreign population is relatively small, so the percentage of myopia is certainly not as high as in China.

I'm ashamed to say that I'm one of the myopic people. Hey, I'm short-sighted because I was fascinated by Detective Conan, and I thought he was handsome when he pushed his glasses, so I wanted to wear glasses too! Now I regret dying.

But now there are really more and more myopic people, and there are four out of ten places where my company works. It's all relatively young. Most of them are myopic because of watching TV dramas, playing with mobile phones, and studyingTarget.

The reason we are nearsighted is because we need to do more homework than children in other parts of East Asia. And the older the child, the more time they spend indoors. Children in China are often asked to take a nap after lunch instead of playing outside, and long homework hours begin after dinner.

This is very bad for the eyes, so it causes myopia.

Nowadays, the number of myopia among primary school students is also increasing, and a large part of it is due to early exposure to electronic products. When we were younger, we would talk about going out to get in touch with nature and outdoor activities, but nowadays children really give them an electronic device and they can play for a day. And basically the children of the family have been playing with their mobile phones for them very early, and they have more mobile phones and tablets than us.

This is very disadvantageous for children who are still growing up, so it is now common to see five or six-year-old children wearing glasses on the street.

It's hard to be sophisticated because no one has to check your eyesight. In ancient times, the lighting conditions were worse, but ** were all the same, only candles, scholars read at night, and women were red at night. However, in the past, there were no hospitals and doctors to help with myopia screening, so even if myopia was present, it was not necessarily possible to diagnose it.

There is no basis for this, because there was nothing that could measure myopia in ancient times, probably because China has too many people, so there are many myopic people in China and other countries.

Myopia is related to the individual's eye habits, and there have not been so many myopic people before.

It's not that it's just that now with the popularity of mobile phones and computers and TV, most of the people who were nearsighted in the past were readers.

No, myopia is related to personal habits, reading too many electronic products, reading too many books will cause myopia, and a small part is related to genetics.

Since ancient times, it has been a high-incidence area of myopia, and in ancient times, people did not have such bright lights, and they were very dark with oil light.

In ancient times, women's myopia occurred more frequently, because women often did some things that were popular with women, which hurt their eyes, and there were also reading men who read at night.

I think there must be, but there were no eyes in ancient China, but in ancient times, people did not have the awareness to prevent myopia.

The reason why I see too much now is that people like to be active indoors and don't receive enough natural light

Science shows that it is caused by eye exercises, but you understand, because it is not allowed to go against xx here, and eye exercises are advocated and guided by xx, so all conclusions are stifled.

Myopia is related to accommodation, that is, when adjusting the resting state, the eye does not use any external force and effort, after the parallel light enters the eye, he is not focused on the retina, he is focused in front of the retina.

In the hyperopic eye, the obvious eyeball is short, and the object image falls in front of the retina, and in the myopic eye, the object image falls behind the retina. Therefore, the retina caused by any reason, his focus should be long, that is, focused in front of the retina, which is manifested as myopia. The main manifestations of myopia are clear near and blurred vision, and the reasons for the formation of myopia are genetic factors and environmental factors.

General genetic factors are said to be high myopia, as if there are more genetic aspects, acquired by the environment, infant and early childhood he behaved normally, and later affected by environmental factors, he formed myopia, which is called acquired myopia, sometimes we also call it functional myopia, so the formation of myopia from the current point of view, is basically these two major factors.

One is congenital, generally congenital myopia when he is two or three years old or even four or five years old, if we find that his myopia degree may be thousands through optometry, which is generally congenital hered.

Environmental factors are mainly long-term close work, such as reading a book, writing, carving, especially now looking at mobile phones, watching TV and other fine work caused by excessive auxiliary adjustment, so that the internal and external rectus muscles, we know that there are muscles outside the eyeball, and its internal and external muscles compress the eyeball, so that the eyeball becomes longer and causes myopia.

On the other hand, long-term close work can make the adjustment tension, eye congestion, and intraocular pressure increase, all of which can make the eye axis longer. Especially in the case of insufficient light, insufficient light, when looking at things, it is generally not clear to see clearly, in order to see clearly, we have to see closely, after working at close range for a long time, in order to see the target clearly, so that the two eyes are very close to the target, which is the main cause of myopia.

Therefore, myopia generally means that acquired myopia is caused by the environment, and at the beginning he is emmetropic, and after poor eye hygiene, he forms a kind of pseudomyopia. After a long time, pseudomyopia, without adjustment, without **, he will become true myopia.

And if you don't use your eyes properly for a long time and don't pay attention to hygiene, the degree of myopia will also increase, and it will develop, and it is often seen in clinical practice that some children may be about 100 degrees of myopia when they are teenagers. When you reach junior high school and high school, you may develop to a degree of myopia, so functional myopia is mainly related to environmental factors, and environmental and genetic factors are also mutually restrictive, and they are not absolutely separate.

Among the total population over 5 years old in China, the number of people with various types of distance vision defects is about 500 million, of which the total number of myopia is about 100 million. It can be said that almost one out of every three people in China has myopia. Without effective policy intervention, by 2020, the prevalence of myopia in China's population over 5 years old will increase to about 51%, and the number of people affected will reach 700 million.

In August 2018, the Ministry of Education, the National Health Commission and other eight departments jointly issued the "Implementation Plan for the Comprehensive Prevention and Control of Myopia in Children and Adolescents", which put forward the goal of controlling the myopia rate of 6-year-old children in China at about 3% by 2030. The prevention and treatment of myopia refers to a topic of national concern.

However, the current myopia problem in the country has spread to the point that the proportion of children and adolescents is still high. According to the press conference held by the National Health and Construction Commission in April 2019, the results of the 2018 myopia survey of children and adolescents in China showed that the overall myopia rate of children and adolescents increased from the first grade to the sixth grade in primary school, and the number of people with high myopia (myopia more than 600 degrees) in the third grade accounted for the total number of near-limb orange vision.

It's so flooded that when I go to pick up my kids from school, three or four of the 10 kids who come out of school wear glasses, ......

I feel that when we were young, the myopic friends around us were not so exaggerated, and we had to wear glasses, which was more when I was in junior high school and high school, and it was really not like the glasses that were as thick as beer bottle caps at a young age like now. Maybe it's really that we didn't have so much contact with electronic products as children now, like my baby picked up the mobile phone as soon as he came home, and he didn't leave his hand after writing homework, plus he took online classes at home during the previous epidemic, facing the screen every day, I was really more worried about his eyes than himself.

Originally, I told him, don't tell me that you regret it if you don't protect your eyes now, but he still didn't listen, saying that I scared him, and then he couldn't see clearly on the blackboard in class, what else could I do? I can only take him to the hospital for examination in a hurry, for fear that he will also wear glasses at a young age. Fortunately, the doctor said that it was pseudomyopia, and that it was overused and the nerves in the eyes were tired, and this situation could be alleviated through vision training without glasses.

After I got home, my dad and I hurriedly did our homework, and saw that many people were recommending the Fire Eye Crystal E1Pro Smart Vision Trainer, this brand was not very well known before, but it was said on the Internet that it had a new VR technology visual health certificate this year, as well as the German TUV Rheinland low blue light certification, which feels quite reliable.

I happened to find out that there is an offline store near my home, so I took my son to try it, and the clerk said that the product was experienced on site for 6 minutes, and there was a temporary effect of improving the naked eye vision, and children aged 6-12 years old could have a permanent effect if they insisted on using it for 2-4 weeks. I tried it on the spot, and there was not only ciliary muscle training - simulated distant view, but also refractive system-related training (Xiaokuan involves visual accommodative training, visual sensitivity training, contrast training, and eye-brain cooperation training content), I felt that it was quite effective, so I directly placed an order and bought it home.

This fire eye crystal e1pro has a parent's end app,You can establish a vision file on it,You can give a training plan according to the child's specific situation,I let him train against that plan every day,15 minutes or so,He didn't say anything,I hope this time I can settle down for a little longer。

Nowadays, there are fewer ways for children to be entertained, except for mobile phones, televisions and computers.

Because today's teenagers have been playing with electronic products since childhood, and their eyes are overtired.

Because teenagers overuse their eyes. Staying up late often leads to vision loss.

Nowadays, teenagers are increasingly obsessed with mobile phones and TV, which promotes the high incidence of myopia.

Because teenagers use their eyes excessively, not only in learning. And also on electronic devices. Excessive use of the eyes.

Because of the development of technology and the abundance of electronic products, children inevitably have to play with electronic products such as mobile phones or computers, which leads to an increasing rate of myopia.

Because nowadays teenagers are under the influence of electronic products, the vision of the eyes will gradually decline.

Because there are more and more electronic products nowadays, many teenagers have started to play with mobile phones and computers since they were young.

Because teenagers don't know how to prevent myopia, and they are all controlled by mobile phones, it is easy to cause myopia under mobile phone radiation.

As we all know, children's eyes are short-sighted, and their studies and lives will be affected when they listen to classes at school, and their desire to join the army cannot be realized, let alone become a pilot. If the degree of myopia is large, things that are a little far away will not be visible, and it will be blurry, and it will be difficult to distinguish fine things, and it is easy to be dangerous at work. So what causes myopia?

1. Genetic factors.

It is recognized that there is a certain genetic predisposition to myopia, especially for high myopia, which is also one of the common causes of myopia.

2. Environmental factors.

Certain environmental factors can increase ocular accommodation to form a certain degree of phototaxis myopia, and it is still questionable whether the eye axis can be lengthened to form axial myopia, but they are all causes of myopia.

3. Eye habits.

Eyesight can be affected by using your eyes too closely, lighting too strong or too weak, sitting incorrectly, using your eyes for too long, reading books and looking at mobile phones in the car or walking, and using electronic devices without moderation.

4. Ideology.

Most people lack the correct understanding of myopia prevention, and some children think: myopia, it doesn't matter, just wear glasses.

5. Nutritional deficiencies.

Some myopia is related to the lack of trace elements in the body, especially the lack of calcium and zinc, or too much absorption of poor sugar foods, which can also lead to myopia, such as junk food, carbonated drinks, snacks and so on.

6. Balance work and rest.

Homework, extracurricular tutoring, and specialty training make children not have enough time to rest, outdoor exercise is reduced, and lack of sleep will also affect their eyesight.

1. Too much homeworkIn fact, you can also think of this reason when you move your toes, now there are more and more children's homework (many of which are online), although the Ministry of Education has repeatedly issued instructions for schools to reduce the burden and pressure on children, but the truth is very cruel.

2. The online class time is too long。Online classes may be a teaching method that broke out during the epidemic, but this online class is not solved in half an hour at all, many of them are hours, and it is strange that the child's eyes are not short-sighted.

4. Parents' ignorance. Students play mobile phones, computers, watch TV, many reasons, is the indulgence of parents, do not guide the child's concept of time at all, of course, this is a big reason because parents ignore their children's education (especially 0-6 years old) age from an early age, many parents are always a variety of work reasons (busy), work is greater than education, many parents go out, leave their children in their hometown, and go away. But have you ever thought about it, who will discipline your children if you leave it in your hometown?

Does it depend on grandparents?
