Prevention is the key to the correction of myopia, and it is recommended to prevent myopia

Myopia is caused by excessive eye use and lack of eye hygiene, so it is necessary to pay attention to eye hygiene and try to reduce contact with electronic products to prevent the occurrence of myopia

The eye is one of the most important organs in our body, and it is easily damaged, and if you don't pay attention to scientific eyes, you will get myopia. If you have myopia, if you want to see distant objects clearly, you have to wear myopia glasses, which is ugly and inconvenient. Therefore, we must develop a good habit of caring for our eyes from an early age, use our eyes scientifically and rationally, and stay away from myopia.

1. Correct incorrect eye habits.

Do you often see such a situation around you: some friends read books at close range for a long time every day, and the rest time is too short; Some friends watch TV, use computers, and play game consoles for a long time. None of them are doing the right thing.

Seeing this situation, you have to tell your friends that these are all bad eye habits and are prone to myopia. You also tell them to keep the distance between their eyes and the book at about 33 centimeters, to rest for ten minutes for an hour of study, not to read while walking or riding in the car, and not to lie down to read.

2. Strengthen eye function training.

You can do this kind of eye function training with your friends: do eye exercises, look into the distance, do blink exercises, do eye blink exercises, etc., to compare who does the best and see who can stick to it.

Do not read books under bright or low light.

Reading in strong or low light will cause uncomfortable sensations such as eye pain and dizziness, and it will also induce and aggravate myopia for a long time.

If you find that your classmates have such incorrect eye habits, tell them that strong light can cause damage to the retina, and visual sensitivity will decrease, and doing this often will cause permanent vision loss; If you read a book for a long time in a dimly lit place, you will develop pseudomyopia, and if you do this often, you will suffer from true myopia.

Increase physical activity.

Among all kinds of physical exercises, table tennis has the most obvious effect on the prevention and treatment of myopia. Students can call their friends to play table tennis between classes, after school, and during holidays. Doing this regularly both exercises the body and prevents myopia.

Eat a balanced diet.

Picky eating can also lead to myopia. Eating more carrots, spinach, leeks, green peppers, cucumbers, cauliflower, cabbage, sweet potatoes, oranges, apricots, persimmons, fresh dates, pears, cereals, beans, milk, meat, animal offal, fish and shrimp, eggs and other foods can effectively prevent the occurrence of myopia.

Once you have myopia, there is no way to do it**. The vast majority of teenagers are preventable, so every teenager should establish the concept of prevention before it happens, and master the correct preventive measures.

Myopia prevention refers to a method to prevent myopia by correcting posture and shortening the time. The incidence of myopia in China is still increasing day by day, and medical experts believe that the visual environment is the main cause of myopia, rather than eye habits.

The essence of myopia is that the regulatory function of the eye muscles declines, resulting in distant light passing through the refractive of the eye, and the focus falls in front of the retina, and a clear image cannot be formed on the retina. It can be seen that in order to prevent myopia, it is necessary to avoid excessive tension of the eye muscles, which leads to the decline of their regulatory function.

Isn't it a little embarrassing to let me, a short-sighted eye, answer this question, then I'll treat it as a negative teaching material.

Some data show that nowadays, the incidence of myopia in China is showing a trend of low age, and the current myopia population in China has exceeded 100 million, of which the high incidence area is the age group of adolescents aged 10-18, and the poor vision rate of primary, junior and senior high school students in the country is and, and the incidence of myopia among adolescents in China has surpassed that of other countries, ranking first in the world.

There are many people who blame the increase in myopia rate on the heavy workload of students nowadays, which is naturally one of the reasons, but it is not entirely the reason. Many people have myopia due entirely to incorrect eye posture (or eye hygiene) and prolonged exposure to electronic devices.

So, what can be done to mitigate this phenomenon?

Eat a varied diet.

The development of myopia is sometimes associated with an improper diet. Excessive sugar intake will consume a large amount of vitamin B1 needed for nerve impulse conduction, causing optic nerve dysfunction. At the same time, sweets will lead to a decrease in calcium in children's bodies, and calcium deficiency can reduce the elasticity of the eyeball sclera, and in the long run, form axial myopia in children. This aspect is easy for many parents to ignore.

Therefore, in order to ensure the health of your eyes, you should eat a varied diet and avoid excessive intake of sweets.

Get enough sleep. Studies have shown that if children lack sleep for a long time, it will cause systemic autonomic nerve dysfunction, which in turn affects the dysfunction of the ciliary muscle of the eye, leading to the formation of myopia. Therefore, it is also very important to ensure regular and adequate sleep to prevent myopia in adolescents. Many parents do not pay attention to their children's schedules and cannot ensure adequate sleepAfter the child is short-sighted, he simply blames the child, but he does not think that there is also the responsibility of the parents.

Sit upright. Sitting in a correct posture may not have an immediate effect, but it will subtly affect the child. Parents must always pay attention to and correct their children's bad sitting posture. If you can combine it with eye exercises, you can better protect your eyesight.

Keep away from electronics.

In today's society, the phenomenon of obsession and even dependence on electronic products is very serious. Electronic products are easy to indulge children, and it is easy to cause eye fatigue, make the eyes dry, sore, and other discomforts, and it is also easy to cause myopia. This point, in particular, should be paid enough attention to by parents.

The last point is to improve learning efficiency and reduce the time spent on homework.

In short, myopia can be prevented and controlled, pay attention to eye hygiene, reduce the environment of bad eye use, and take care of your eyes seriously, you can get rid of the trouble of myopia.

on the Internet, invasion and deletion.

1 in 3 children is nearsighted, don't let your child be that one!

Look less at electronic screens, be sure to rest your eyes more, and study or do homework in a sunny place at night. It is best to do eye exercises at home, go to bed early, and rest early is also a kind of protection for the eyes.

Now the only way to alleviate this phenomenon is to keep children out of contact with electronic products, but this is very unrealistic, and now learning is inseparable from these, some homework needs to be completed on the computer, and we can only control the time they play.

To prevent myopia is not to read for too long, to do the posture correctly, not too well or to read a book, after reading the book, do a rock drill and eye drops.

The myopia rate of teenagers is increasing year by year, in order to alleviate this phenomenon, let teenagers combine work and rest, and at the same time, stay away from mobile phones, often relieve their eyesight after studying, and can look into the distance.

Reading and learning is an arm's length away from playing with your phone once an hour.

In today's information society, we cannot mechanically reduce the use time of electronic products, but let screen manufacturers improve their screens. Removing the backlight of the LCD display and relying entirely on reflection is an effective way to reduce the damage of the screen to the level of a paper book (for TVs, the damage will be less due to the long distance).

Don't play with your phone or computer too often, and look into the distance every 20 minutes.

Play less on your phone, computer, and read more.

Do more eye exercises and stick to physical exercise.

Ways to prevent myopia are:

1. When reading a book or looking at the computer, don't keep staring, you should turn your eyes more and exercise more, your eyes are like our bodies, they need to be exercised.

2. Look at more green, if there are green plants nearby, you can look at green plants from time to time, green has a soothing effect on the eyes. I often read a book or look at the computer at close range, and I need to occasionally look into the distance to relax my lower eye muscles.

3. Do eye exercises: eye exercises are very helpful for relieving eye fatigue and dryness, often read books or look at the computer can do eye exercises every two or three hours, massage eye acupoints.

4. Blinking: Blinking can relieve eye fatigue and dryness, which is very beneficial to the eyes, and this method can be done anywhere at any time, which is very convenient.

5. Ice packs for eyes: Before going to bed, applying ice packs to the eyes can not only reduce swelling, but also help relieve eye fatigue.

6. Don't read in a dim place, don't turn off the light to look at the computer, and don't read in the backlight or in the sun.

7. Eat more purple fruits and vegetables, as well as fish.

8. Regularly supplement vision nutrients, and general doctors recommend oral eye vision nutrients, and insist on taking them for a period of time every year, which can protect vision and prevent the occurrence of myopia.

First of all, in ordinary life, let children develop a good habit of using their eyes, pay attention to the posture of writing and reading, try not to look at or look less at electronic products such as mobile phones, read books, write homework and other close eye time should not be too long, stop and rest for about 40 minutes, do more eye exercises, increase the time of outdoor activities as much as possible every day, look at things in the distance, ensure adequate sleep and balanced nutritional intake, and don't be picky eaters. Go to a regular hospital for eye and optometry examinations.

How can myopia be prevented? Star Awareness Project

The professor at Harvard University tells you: to prevent myopia in children, you only need to do one thing. It's that simple, can you stick to it?

The prevention of myopia mainly starts from the aspects of concept awareness, eye habits and eye adjustment.

1) Conceptual awareness: myopia is not only universal, but also has a certain degree of harm, myopia patients have different degrees of reduced eyesight, visual function is damaged, will have a certain impact on learning, work and life. Myopia focuses on prevention, and it is necessary to improve the concept of protecting eyesight and strengthen the awareness of myopia prevention.

2) Eye habits: The prevention of myopia is inseparable from the development of eye hygiene, when reading a book, under bright natural light, maintain a correct sitting posture, avoid lying down and reading on the stomach, and add a lamp on the side of reading or writing at night to keep the light evenly and choose a stable light source; Do not read for a long time, and let your eyes get enough rest for about 40 minutes.

3) Ocular adjustment: After using the eye for a certain time, you should look into the distance and adjust the eye muscles appropriately; Increasing outdoor activities, a wide range of eye movements, and a wide field of vision are essential for the prevention of myopia; Cooperate with appropriate eye exercises, 2 eye exercises a day, and not too much.

The writing posture should be correct, the distance between the eyes and the book is about 30-40cm, the sitting posture should be upright, do not tilt the head, do not lie down to read, do not walk to read. 2. When writing homework, you should adjust the light, the light is too strong or too weak is not good for the eyes, it is recommended that the eye protection lamp and the ceiling lamp are turned on at the same time. 3. Reduce the time of watching TV, watching the computer and playing with mobile phones, avoid long-term close-up eyes, it is recommended to use your eyes at close range for about 30 minutes, and you should look at it for about 10 minutes.

4. Do eye exercises often to relax the ciliary muscles. 5. Encourage children to get close to nature, do more outdoor sports, and soak up the sun, studies have shown that more than 2 hours of sunlight exposure every day can effectively prevent the occurrence of myopia. 6. Balanced nutrition, eat less sweets, studies have found that children who eat a lot of sweets have myopia earlier than children who usually do not eat sweets.

If it is an LCD screen and the distance is not too close (less than 50 cm), the radiation is basically not important. But people have a psychological role, want to wear a pair of glasses to prevent radiation, if you don't have a bad money, it doesn't matter if you have one, seek a psychological comfort.

However, as long as it is glasses, there is always a refractive index problem, and some of the light that enters the eye through the lens is filtered out. In this case, it takes more work for the eyes to see clearly, which invisibly increases the burden on the eyes, and it is easy to get tired. So, still don't wear glasses.

There are ways to protect your eyes when looking at the computer for a long time, as follows:

1.It is best to face the computer screen away from the window or sideways to avoid reflections.

2.The height of the computer console should be lower than the general tabletop, and the height of the seat should be adjustable. The center of the computer screen should be at the same level as the chest.

3.The distance between the computer screen and the eyes should not be less than 50 cm, and the line of sight should be 10-20 degrees lower than the level line of sight.

4.The light in the computer room should not be too weak or too strong (a 40 watt fluorescent lamp in a 12 square meter room can achieve the required illumination).

5。It is best not to look at the computer continuously for more than 1 hour, and the eyes should blink non-stop, more than 20 per minute. When your eyes are tired, be sure to close your eyes and rest, or go outside to look into the distance. There's also a way to cover your eyes, you can go to my space to check it.

Vision protection should be insisted on, and I wish you good eyesight.
