The myopia rate of primary school students is over 50, it is recommended to have a physical educatio

From the medical aspect, it can relieve visual fatigue, and primary school students can easily cause visual impairment if they do not move their eyes when they read books, and outdoor sports can effectively protect their eyesight.

Regular participation in outdoor activities can make the eyes look into the distance, and you can also look at the surrounding greenery, which can relax the eye muscles, so as to protect and improve the vision condition.

The myopia rate of primary school students is over 50%, and it is recommended to have a physical education class every day, and outdoor sports have a protective effect on children's eyesight. Outdoor exercise can reduce children's eye fatigue and relax children's visual nerves.

Outdoor exercise can properly alleviate eye fatigue, when primary school students study in the classroom for a long time, it will make the eyes sore, at this time, go outdoors to see the green grass, leaves, can relax the eye muscles, reduce the occurrence of myopia.

I think that outdoor exercise can relieve everyone's eyesight, and it will allow students to relax their eyes enough in their leisure time.

Ensuring full exposure to sunlight, promoting the development of the eyeballs, and ensuring that primary school students have 1 hour of exercise every day plays an important role in the physical health of students.

1) The answer is yes.

At present, outdoor activities can prevent myopia, and there are two more accepted theories: first, strong light irradiation narrows the pupils, and the narrowing of the pupils will deepen the depth of field and reduce the blur; Second, the light is brighter, which can increase the secretion of dopamine and enhance the absorption of nutrients in the eyes, thus having a positive effect on the prevention and control of myopia. Both of these statements believe that what really works is the time spent outdoors, which is related to light, so staying at home probably won't do much to prevent myopia.

Although high-intensity light, than low-intensity light, is more conducive to inhibiting myopia, many people know, but the difference between outdoor and indoor is not only in the brightness (the brightness of the two is not at the same level, even if it is cloudy, the outdoor brightness is much higher than the indoor brightness). Outdoor light is dynamic light, indoor light is basically static, dynamic means that the eyes are always adjusting and moving; Outdoors also means more distant views and the eyes can be adjusted. If children can insist on two hours of outdoor activities in the daytime with good light every day, it will help to do a good job in myopia prevention and control.

2) What should you do if your child really doesn't have time to spend outdoors every day?

Two hours of outdoor activities during the day can indeed effectively help children prevent and control myopia. However, due to various reasons such as geography and weather, many children are unable to guarantee the above outdoor activity time, so what is the way to make up for the lack of outdoor light time for children?

Targeted photon uses the principles of gene targeting biology such as optogenetics and nutrigenomics, and combines biophotonic technology to innovate and develop a photobiomodulator.

The product can simulate the beneficial spectrum in sunlight, meet the signal regulation needs of 9 opsins in different frequency bands, and regulate the synthesis of substances (such as melatonin, melanopicin, dopamine, choline, etc.); At the same time, the beneficial spectrum can promote the metabolism of fine cluster megacells, promote the synthesis of vitamin D3, and then promote the absorption of calcium ions. The full absorption of calcium ions is beneficial for maintaining eye health. In addition, it produces a beneficial spectrum that promotes collagen production.

The lens and cornea of the eye are composed of collagen, which is also good for the production and synthesis of photosensitive proteins, and collagen can also affect the transparency, elasticity and thickness of the lens and cornea of the eye, which has a positive impact on the prevention and control of myopia in children and adolescents.

The announcement of the myopia rate of children and adolescents in China has attracted everyone's attention, and the myopia rate of more than half of children and adolescents has attracted discussion. On the one hand, the myopia rate of children and adolescents reflects the academic pressure faced by children and the living environment brought by electronic technology. One of the things that children face is the heavy workload of schoolwork, and the other is that under the development of the city, the high-rise buildings and electronic products are limited, and the children's entertainment methods are limited.

How should elementary school students use their eyes correctly?

Not long ago, various online games further strengthened the health system for minors, imposed time limits on minor gamers, regulated the time of minors playing games, and prevented minors from indulging in games. However, myopia is not all caused by electronic devices, and in any case, long-term use of the eyes and fatigue of the eyes may cause damage to the eyesight. The eyes are the windows of the soul, and wearing glasses for a long time is not only troublesome, but sometimes it can also affect a person's spirit, not to mention that myopia can bring limitations to some professions.

As minors, primary school students lack self-management awareness, and how to make children use their eyes healthily and protect their eyes needs the guidance of parents and teachers, as well as the support of policies.

Primary school students' school time should be reasonably arranged, and the class time should be in accordance with the specific time regulations, not to delay classes, not to add classes, and to guide children out of the classroom to walk around, and not to occupy eye exercise time to lecture. Nowadays, everyone is seriously involuted in learning, and parents will worry that other children will surpass their own children when they have a little free time. Specific achievements such as school performance and promotion rate can be directly seen, which leads to the neglect of children's physical fitness and whether they are all-round development of morality, intelligence, physique and beauty.

Elementary school students need the guidance of parents and teachers to use their eyes correctly. First of all, refuse to use electronic products for a long time, and then start from controlling the time of eye use, how to master the correct sitting posture, not scumbag cavity nucleus to sit for a long time, stipulate the necessary exercise time, and maintain the child's health while protecting the child's eyesight.

Primary school students should not stare at the electronic system for a long time, keep a safe distance when reading, look at the green plants after class, and eat more fresh vegetables and fruits to protect their eyes.

Use your eyes moderately, look into the distance every once in a while to rest your eyes, and keep a correct posture and distance from reading a book or mobile phone.

Adjust your sitting posture, eat more foods that protect your eyes, and play less with electronic products, so that you can protect your eyes.

Students are mainly focused on studying, so many times students study for a long time, which is more likely to lead to eye discomfort, which leads to myopia. According to the survey, the myopia rate of primary school students exceeds 50%, and the committee members suggested that one physical education class should be guaranteed every day, which I think is very necessary, because it can not only relieve stress, but also reduce the increase in myopia rate.

Nowadays, many schools are biased towards students' learning, thus ignoring the health of students, resulting in long-term learning of students, forgetting to relax their eyes, students' eyes are too tired, and they will slowly become myopia, which is also the reason for many primary school students' myopia. Education is the foundation of the country, and only by cultivating the development of children in all aspects is the real education. Because without a good physique, students simply cannot devote themselves wholeheartedly to learning.

Even a long time ago, China emphasized that every school should have a physical education class, which is to reduce the psychological pressure of students, so that they can better continue to devote themselves to learning.

The role of physical education class is also very large, you can learn how to unite classmates, if you are under the pressure of studying for a long time, there may be depression, through physical education class can solve this depression, to achieve the role of communication with others, so it also plays a very important role in the mental health of students.

Our eyes should not stare at an object for a long time, because staring at an object for a long time without moving will lead to dry eyes, and even tears, which may further aggravate the possibility of eye lesions, so it is very necessary to do this for the sake of children's eye health.

In fact, it is not enough to recommend that there is one physical education class every day, because there is no corresponding compulsory measure, so many schools will only pretend to set the curriculum as physical education, but in fact it is still some Chinese, mathematics, English and other courses. So I think that if a school is found to have failed to do so, it should be punished by the relevant school, for example, its school can be rectified.

Personally, I think there can be, and now the child's body is really not as good as we were at that time!

It is recommended that more and more children now only stare at books.

Very good advice, now that the education development of the whole of China is lacking a hands-on and body-friendly education system, we can't just focus on scores, which is a good suggestion.

This is important. Nowadays, the myopia rate of students is increasing, and the addition of physical education classes is not only conducive to vision protection, but also beneficial to physical health. It is necessary for primary school students to increase physical activity, which can be helpful on both a psychological and physical level.

Nowadays, the myopia rate of primary and secondary school students is getting higher and higher, in fact, we don't know what to do, because the learning pressure of primary and secondary school students is getting bigger and bigger. With the increase of learning pressure, these primary and secondary school students are using more and more eyes. Therefore, at this time, most primary and secondary school students have already worn glasses.

And we need to know that after the child is tired of using his eyes, we must let the child look into the distance. Allowing your child to look at the greenery will also reduce eye strain.

After long-term use of eyes, we must look into the distance, and we should also refuse children to play with mobile phones often or look at the computer for a long time. And letting children use their eyes scientifically can also help children reduce some myopia. Therefore, at this time, we must pay attention, for example, if some children are always tired to see something, then we let the children reduce the occurrence of this phenomenon.

After the child has been learning for a while, we let the child relax, walk on his own, move, and look into the distance, which can also help the child solve the problem of myopia.

Looking at green foods can reduce this phenomenon, and everyone knows that children do recess exercises when they go to school, and when they do recess exercises. We must let the child do recess exercises seriously, and we must do eye exercises seriously, only in this way can we make the children's eyes more energetic. We also have to go out and play at the end of class, and don't always stay in the classroom to read.

If we stay in the classroom and read books all the time, our eyes will become more myopia.

In the same way, we must keep a safe distance when we are playing with our mobile phones or reading books. Some children always like to lie on their stomachs to look at things, which is also very wrong. We must know the scientific use of eyes, so that it is very good for our eyes, and we must also reduce the occurrence of some myopia.

It is necessary to pay attention to the posture of writing not too low, and at the same time, pay attention to the use of eyes, and do not write homework or study in poor lighting. Don't play with your phone and electronics too much.

He said that he should regulate their reading and writing time. That is, we should pay more attention to daily eye cleaning, and we should also have a prescribed time for rest and relaxation in daily reading and writing, so that our eyes are not overtired.

When using a computer, writing, and working, you should maintain a correct sitting posture, and keep the right distance between your eyes and the paper at a distance of about one foot. Don't lie down and read a book or newspaper, and don't stay up late with your eyes. After learning to relax your eyes for a while, you should stop what you are doing and look into the distance to relieve eye fatigue.

Also, don't sit next to the computer for a long time, it's easier to be nearsighted next to the TV.

Give students time to use their eyes, such as taking a 10-minute break for one hour of eye use, and up to eight hours a day.

Lead students to do eye exercises and let them relax their eyes appropriately.

Give them the knowledge of eye protection and let them know the importance of using their eyes wisely.

I think it's mainly in school, first of all, children must be allowed to go out for activities during recess, and secondly, don't leave too much homework, otherwise if children use their eyes too much, it will definitely lead to myopia.

Usually after class, you must take a break for a while, and then you can also choose to look into the distance, and then be sure to reduce the time you spend using electronic devices.

According to the research report of the World Health Organization, there are currently more than 600 million myopia patients in China, and the myopia rate of adolescents ranks first in the world.

Some experts said that children should rarely have myopia in the preschool stage of 3 to 6 years old, but in recent years, due to the chain reaction of parents' anxiety about going to school and the heavy burden on children, the myopia rate of 6-year-old children has risen year after year, and the phenomenon of myopia at a young age has become increasingly significant.

When children enter school, there are more and more opportunities to use their eyes, and parents mainly emphasize that children should pay close attention to learning, but ignore the physical and psychological development of children, and do not provide correct guidance for children's eye problems, so that there are more and more myopia, and the age of disease is gradually advanced.

However, this year, due to the impact of the epidemic, children cannot go to school and can only learn online at home.

Therefore, through the data of recent years, parents should pay attention to avoid the problem of myopia in their children. So, in daily life, how can parents correctly guide their children to use their eyes scientifically and protect their eyes?

1. Pay attention to the time you spend with your eyes.

In this era of rapid development of information, there are more and more electronic products, such as mobile phones, computers, tablets and so on. If the child is exposed to too much contact, it is easy for the baby to develop myopia, and the blue light produced by the screen of these electronic products is particularly damaging to the eyes. Therefore, parents should control the time their children use electronic products, and cannot exceed the prescribed 1 hour per day.

Because the child's eye development is not perfect enough, the concentration is relatively low, every time you read or write for an hour, you have to go to outdoor activities, 5 10 minutes of distant viewing plus eye exercises, is the best relaxation of the child's eye muscles after reading and writing for half an hour.

2. Master the posture of using your eyes.

To develop the correct habit of using the eyes, to maintain the correct posture when reading and writing, the head should be straight, the back should be straight, the distance of 33 cm is the best distance between the eyes and the book when the child reads and writes, and it is also a scientific means to protect the child's eyesight.

3. The light of the eyes should be appropriate.

When the light is not good, the eyes will be over-adjusted, for a long time, it will cause eye fatigue, resulting in vision loss, therefore, when the child reads and writes, it is necessary to choose the right light, according to the national standard, the light brightness suitable for learning is about 300-500lux, parents should prepare for their children in advance.

Fourth, pay attention to the exercise of the eyes.

Exercise can keep your eyes well maintained and your vision good, so parents can take their children to get involved in outdoor activities every day to help relax while promoting blood circulation in the eyes.
