Preface
I don't know if you have found such a problem, most of the friends around me have glasses, this is definitely not an accidental reason, 60 years ago, the myopia rate in the mainland was only about 10%~20%, but with the rise of the electronics industry, this proportion began to expand rapidly, as of 2022, the proportion of myopia in the mainland is as high as 50%.
Among them, the myopia rate of high school students and college students has exceeded 7 percent, and the myopia rate of primary school students has also come to a terrifying 40%, this data is very scary, which means that if you do not rely on glasses or myopia surgery, the world in their eyes will always be blurred, if the degree is relatively high, it is definitely not a joke to recognize the six relatives within 5 meters.
So what is the reason for the soaring myopia rate in mainland China, and how can we prevent myopia or alleviate the severity of myopia?
The rate of myopia has soared
First of all, we must first clarify the cause of myopia, the first is genetic factors, if one or both of your parents suffer from high myopia, then the probability of myopia in the next generation will be greatly increased.
The 90s was a blowout period of electronic products, TVs and button mobile phones were very addictive, and even without these, the popularity of electric lights also greatly aggravated the probability of myopia.
Evenings have also become a lot of people's entertainment time, lying in bed watching TV, or lying in bed reading novels, these incorrect ways of using eyes in exchange for myopia, and once you develop Xi habits, it is difficult to correct, so the previous generation of high myopia came from this.
Then with the previous generation for the "base" to geneticize, and then this generation has more abundant entertainment methods, and the use of various mobile phones and tablets to the face, the myopia rate in the mainland has come to this point.
For example, some people may be myopic with a little eye, and some people play with mobile phones every day The vision of the eye is still 5.0, although there are genetic reasons but only a small part, the bigger reason is improper use of eyes, not that your parents are myopic you will definitely be myopia, but there is a genetic probability, and the acquired eye Xi is the big head.
Even if your parents are not myopic and you do not have a good eye Xi, myopia is only a matter of time, and there is a special reason for myopia, that is, the lack of trace elements in the body will cause myopia, which needs to pay attention to the usual nutritional intake.
With the increase in the proportion of myopia among teenagers, more and more people have begun to pay attention to this problem, some time ago some people questioned the current teaching model, especially after the epidemic, there are more and more voices of doubt, this is mainly because of the progress of technology, teachers used to write with chalk in class, and children stared at the blackboard.
But later, after the popularization of multimedia blackboards, the current schools basically use smart blackboards, students stare at the screen every day, especially the students in the front row, the eyes are more radiated, and they used to worry that their children sat in the back row and could not see what the teacher wrote on the blackboard.
Now I am worried that my children will sit in the front row, staring at the screen every day and use their eyes badly, during the epidemic, students are taking online classes at home, and this model has been retained to a certain extent after the epidemic, and some schools will still have online class content, which makes the burden on students' eyes more serious.
In fact, in the previous era when electronic products were not popularized, students at that time used incandescent lamps in class, and even lit candles in the event of power outages, and stayed up late at night to study Xi the lights were also dim, and the test of these situations was also huge, but at that time there were not many people who were short-sighted.
Therefore, some experts put forward their own opinions, believing that the reason why the proportion of myopia is so high is that there are no rich extracurricular activities.
And today's students, not even between classes, and even physical education classes can't be guaranteed normally, it's good to have one session a week, and even if it's a physical education class, it's not for nothing to watch teaching videos indoors, and after school, writing homework and playing with your mobile phone has become the only way to entertain.
The probability of myopia if the eyes are not relaxed will naturally come up, but the mainland has also been paying attention to this problem, and has made many measures to save it.
Prevention of myopia
The first is the "double reduction policy" policy for students, which stipulates that written homework cannot be assigned in the first and second grades of primary school, homework time from grades three to grade 6 cannot exceed 60 minutes, and homework completion time in junior high school cannot exceed 90 minutes, which was unimaginable before.
Students have sacrificed their time after school for homework, and even some key school homework can make you write until the early hours of the morning, and now the homework burden is greatly reduced, freeing up more time for students to enrich extracurricular activities, but when this suggestion was first put forward, the response was very average.
It can even make this policy more smoothly to achieve the desired effect, directly on the off-campus training, the tutoring institutions were directly cut in half, and high school students also ushered in the burden reduction, although they are preparing for the college entrance examination, but the health of the body is always in the first place.
In the past, high school students even completed all their homework for 3 years in the first two years, and the remaining year went all out to resume Xi and mock exams, and they had to stay up late every day, and it was normal to go to school on Saturdays and Sundays to make up for Xi, and even statutory holidays had to make up for Xi, but the double reduction policy has come and the rhythm of high school students' learning Xi has returned to normal.
However, it is not enough to reduce the burden on the policy, we must also establish a correct concept, there are several misunderstandings about myopia, and a little carelessness will make myopia more serious.
Misconceptions about myopia
Regarding myopia, we must first clarify a concept, a special research institute has done such an experiment, if an 8-year-old myopic child does not control him to play freely, to the age of 16 myopia has come to 900 degrees, what is the concept of this degree? Take the mobile phone as an example, 900 degrees of myopia and the mobile phone to keep a fist distance to see the words on the screen, if the intervention is carried out in the early stage of myopia, then the degree of myopia can be controlled at about 300 degrees.
And most of us have a big misunderstanding during this period, thinking that children are myopic only if they can't see clearly, but in fact, myopia is already very serious at this point, if your child is sitting in the front row and can't see the blackboard clearly, the degree should be about 400~600, if it is the back row, it is about 150~300.
At this time, parents should take the initiative to observe to see if the child is struggling to see, and to check the child's eyesight regularly, find it early and carry out adjuvant treatment as soon as possible to prevent the child's myopia from becoming more serious.
Myth 2: The more you wear glasses, the more myopic you are, this topic has always been a cliché, we all know that the eyes have a certain degree of adaptability, if you are not myopic to wear glasses with a prescription, then the eyes will automatically slowly adapt to the prescription of the glasses and become myopia.
This also makes some parents think that the glasses are more and more myopia, if you don't take it, maybe it will be automatically adjusted, but this practice is wrong, if the myopic child does not wear glasses, then they will see things will form a vicious circle, the more you can't see clearly, the closer you are, the closer you are, the more myopia is aggravated.
Myth 4 thinks that it is okay to wear glasses after myopia, many people think that glasses can make children see clearly normally, it is precisely because of this concept that there are many children with glasses who have just passed 2 years and can not see clearly, and the power of glasses has increased a lot.
Wearing glasses does not mean that you will not increase the degree, he is just an auxiliary tool, if you wear glasses or maintain the previous eye Xi, myopia will definitely worsen, so regular review, and then with the doctor's advice, correct the previous eye Xi, is the most important thing.
