What methods are there to prevent myopia?

Learning aspect

Correct reading and writing posture.

Children's reading and writing posture is incorrect, and reclining or lying flat will lead to eye fatigue. Over time, it is easy to oppress one eye and cause pseudomyopia. Parents should urge their children to always remind them to sit up and write.

Adjust the light when studying.

Light is very important when children study. You must buy your child a desk lamp with soft light and no glare, which can protect the child's eyes well. Even adults should ensure adequate indoor light when studying. The dark learning environment is very harmful to their eyes.

Control the time of study and reading.

Your eyes are very tired when you study and study for a long time. If you don't rest in time, you will slowly develop into pseudomyopia. So after studying for 40-50 minutes, you should rest for 10- 15 minutes, and it's best to close your eyes or look away for a few minutes.

Correct bad study habits in time.

Many children have bad study habits, including adults, such as reading in bed, eating, going to the toilet, reading in a moving car and walking. These bad habits will make your eyes tired and reduce your vision. If you want to prevent myopia, you should give up these bad habits as soon as possible.

Entertainment.

Don't play computer and watch TV for a long time.

After studying, children, including adults, will soak in front of TV and computer. Now these electrical appliances are the chief culprit leading to myopia. Especially some children who play games stare at the computer without blinking, which is very harmful to their eyesight. Therefore, in order to prevent myopia, we should control the time of playing computer and blink as much as possible to make our eyes moist.

Exercise.

Keep doing eye exercises.

Eye exercises can protect your eyes well, and try to do them for a while every day, which is very helpful to relieve eye fatigue. Try to get children into the habit of doing eye exercises from an early age. As long as they persist, it will be of great benefit to protect their eyesight.

Exercise often outdoors and observe for a long time.

Many children prefer to stay at home, play games and watch movies, and don't like going out, which easily leads to myopia. Therefore, parents should usually take their children to the suburbs to play and exercise, which can relax their children's body and mind and protect their eyesight.

dietary respect

Take more vitamin B and minerals.

Vitamin B and minerals are necessary for eye development and functional progress. Usually, you should eat more spinach, animal liver, Chinese cabbage, rape and so on. It's especially good for your eyes. It will make your eyes look bright.

Eat more foods rich in calcium, zinc and selenium.

Calcium is the "protector" of eye tissue. Foods rich in calcium include shrimp, kelp, soybeans, vegetables, milk, peanuts and so on. The zinc content in retina and choroid is the highest, and the foods rich in zinc are oysters, beef, beef liver, pork and eggs.

Regarding how to prevent myopia in children and adolescents, Deputy Director Yang Xiao said: "In fact, the easiest way to prevent myopia is to return to nature and stop or slow down the occurrence and development of myopia by increasing outdoor activities." According to the survey in Singapore, if students increase 1 hour of outdoor activities every day, their diopter will increase by 0. 17D, and the axial length will decrease by 0.06 mm. The research of Zhongshan Eye Center also shows that adding 40 minutes of extracurricular exercise every day can effectively reduce the cumulative incidence of myopia of students by 9. 1%. She stressed that the emphasis of outdoor activities is outdoor, not indoor, because the difference between them lies in light. Outdoor is natural light, with red, orange, yellow, green, blue, purple and other colors, which is very helpful for eyes. Therefore, she suggested that students take a break of 65,438+00 minutes at school for outdoor activities, and they can also read or exercise outdoors after school.

In addition to the interview, the online editor of Family Doctor also learned that because she knew the importance of outdoor activities to prevent myopia, Deputy Director Yang Xiao insisted on trying to get her children to do more outdoor activities many years ago because she was worried about her children's myopia (her own myopia is 400 degrees, her husband's myopia is 600 degrees, and her children's myopia is very likely). From kindergarten to primary school, she asked the children to leave school and receive more natural light. Now the child 14 years old, with high eyesight. Therefore, parents and netizens may wish to refer to it. If time permits, walking children to and from school every day can not only exercise, but also prevent myopia.

Of course, besides increasing outdoor activities, there are other ways to prevent myopia, such as reducing close work, changing incorrect reading and writing posture, and using less electronic products. In addition, the study found that if children improve their diet structure, consume more carbohydrates, fat and energy, and mix coarse and fine foods with vegetarian foods, they can also play a preventive role in myopia.

The prevalence of myopia among primary and secondary school students in China ranks second in the world, second only to Japan. In recent years, the prevalence of myopia among primary and secondary school students has increased year by year. The results of national students' physique monitoring in 20 10 showed that the detection rate of myopia was 40.89% for primary school students, 9.22% for junior high school students, 67.33% for junior high school students, 9.26% for senior high school students and 2.04% for senior high school students. At the same time, myopia patients are getting younger and younger, and some of them have even expanded to children and even school-age children. In addition, the high incidence of myopia is much earlier. The study found that primary and middle school students in Guangzhou began to enter the high incidence age of myopia at the age of 7- 10, and reached the peak at the age of 12. Therefore, it is best to prevent myopia before the age of 7.

As can be seen from the above data, the current situation of myopia among children and adolescents is very serious, so what factors are affecting myopia? Yang Xiao, deputy director, told the online editor of Family Doctor that the influencing factors of myopia mainly include environmental and genetic factors. First of all, genetic factors can not be ignored. According to the study of twins in Zhongshan Eye Center, genetic factors account for more than 70% of myopia. If both parents are nearsighted, the risk factors of children's myopia will increase. Secondly, environmental factors are also very important. Close work, incorrect reading and writing posture, bad visual environment, insufficient outdoor exercise and nutritional factors can all lead to myopia. A statistical result on the incidence of poor eyesight among primary and middle school students in Guangzhou shows that 90.7% of them spend too little time with their eyes, 78.5% spend too much time with their eyes, and 63. 1% of them are reading and writing at their desks. Nowadays, due to the heavy academic burden, the time for students to participate in outdoor activities is obviously reduced, which greatly increases the probability of students' myopia.

People often compare the importance of something with their eyes. A pair of healthy eyes will be of great help to reading, study, work and life.

Unfortunately, due to incorrect reading and writing posture and poor eye hygiene, many students are nearsighted, so they have to wear glasses. As we all know, wearing glasses is uncomfortable and inconvenient, which adds a lot of troubles to people. In order to let us have a pair of healthy eyes, we must prevent myopia.

So how should we prevent it?

First of all, we must master the correct writing posture. This is the "three ones". In other words, the head is one foot away from the table, the body is punched from the table, and the hand is one inch away from the pen tip. Some people think it is comfortable to write on your stomach, but because of this, the distance between your eyes and the desktop is small, which may easily lead to myopia or even strabismus. Everyone should always pay attention to the "three ones" when writing, and their eyesight will naturally improve.

Secondly, we should master the correct reading posture. First, the line of sight should be flat with the book; Second, don't read while lying down. If you lie down and read for a long time, you will get closer and closer, and your retina will be damaged for a long time. In order to see things clearly, you have to turn to myopia glasses.

Third, we should pay attention to the reading and writing environment. Whether in weak light or strong light. Where the light is strong, the light shines on the writing and reflects on the eyes, which stimulates the pupil and makes it contract rapidly. If you look down, your pupils will be damaged. In the dim light, in order to see the words on the book clearly, you have to stick your eyes wide open on the book. After a long time, the distance between the lens and retina of the eye is too long, or the refractive power of the lens is too strong, so that the image entering the eye cannot fall on the retina, but falls in front of the retina, which will also make the eye nearsighted.

Of course, insisting on doing eye exercises seriously at ordinary times will also play an important role in preventing myopia.

Friend, I wish you a pair of bright and healthy eyes!

People often say that the eyes are the windows to the soul. But if we lose this window, we will face darkness. Therefore, eyes are very important to a person.

Eyes are so precious that more and more students don't pay attention to protecting them now. Playing games endlessly, watching writing homework and not paying attention to posture ... Bad habits lead to more and more myopia. Myopia has brought us a lot of trouble in our study and life.

So, how should we protect our eyes? At school, we have five minutes of eye exercises every day, but many students take it seriously and still play. Eye exercises can relax eye muscles, promote eye blood circulation, relieve vision fatigue and make eyes rest. At the same time, we should also pay attention to eye hygiene, do not rub our eyes with dirty hands, and ensure adequate sleep, pay attention to rest and strengthen exercise. Keep a certain distance from books when reading and studying, and sit upright; Avoid using eyes at close range for a long time.

With the development of society, the application of electronic products is more and more extensive. Now, every household is basically inseparable from electronic products. Although they bring us convenience, they are also an important cause of myopia. Therefore, we should also reduce the time of using electronic products.

Once the eyes are nearsighted, it will add a lot of troubles to us. Therefore, we must not take it lightly. We should cherish our eyes and protect them. Having a healthy body and mind is the basic condition for doing things. Take good care of your eyes and let them accompany us all our lives!

We often see some teenagers aged 14 or 15 who are nearsighted. So, how is myopia caused? An important reason is that we don't pay attention to protecting our eyesight. Due to excessive fatigue, our eyes are deformed and become nearsighted. This has brought a lot of trouble to study and life. So we should prevent myopia. There are many ways to prevent myopia, mainly to prevent darkness, proximity, sway and duration. Anti-darkness means not reading or doing hard work in the dim light of bare iron. Some young friends are addicted to reading novels, knowing that it is dark and they don't want to turn on the light. They have been reading at their desks, which is very bad for their eyesight. Over time, it will cause myopia. Avoid approaching, that is, don't read or write too close to your eyes. It is most appropriate to put the book about a foot away from your eyes.

Writing on the desk or reading in bed does not meet this requirement. In order to prevent shaking, as long as you don't do anything conspicuous where you are shaking. Some people read books in a rocking car, or eat books by the roadside while walking in the sun. In this way, the space between the book and the eyes is constantly changing, and the eyes and the muscles in the eyes are constantly working hard. They will get tired after a long time. Long-term prevention means that eyesight-wasting work should not last too long. After reading and writing for about an hour, you should have a rest. It's better to look far away and let the muscles that regulate the lens have a rest.

In addition to these "four precautions", it is best for young friends to "look at the distance" twice a day. The way is to stay in the distance for three minutes, then close your eyes and get out of the way. About a minute later, it suddenly opened. After opening your eyes wide, follow the ball up and down, left and right. This activity can make the eyeball get enough rest, which is beneficial to regulate the function of eye cavity and reduce the spasm of pupil machine. Regular enemy exercises are also a good way to prevent the enemy from approaching.

As long as we do the above methods seriously, we will prevent near death. Young friends with myopia can do this to prevent myopia from deepening and try to restore normal vision.

You must think reading is good! Yes, reading is good, but because I read too much, it makes me wear glasses.

On a winter vacation night, I ate something to get ready for bed. I tossed and turned in bed, but I couldn't sleep. Suddenly, I had a ghost idea. I thought: by the way, I haven't finished reading the books I read during the day! So I crept to the door and opened it. I looked around and saw the door of my parents' room closed. I closed the door carefully. I went to the desk and touched the flashlight with my hand. I took out a book from the bookcase by moonlight, which I didn't finish reading during the day. I accidentally kicked the chair next to me and made a "dong" sound. I was so shocked that I jumped on the bed and lay down for fear of waking my parents and being discovered. I looked around and listened to the sound, but I didn't find me. I got up with a grunt. Take a good book and flashlight, and then go back to my bed and read with relish. I swim in the ocean of books and share joys and sorrows with the protagonist. I fell asleep unconsciously. The next day, I quietly put the book and flashlight back where they were. Fortunately, my parents didn't find out.

I have read books in the quilt several times, and my writing is too close to the book, which makes me nearsighted. Once, the teacher wrote many concepts on the blackboard, but because of too many, the teacher wrote much smaller. This really hurts my eyes. It happened that I left my glasses at home, so I had to narrow my eyes into a line, but the efficiency was too poor for me to see clearly. I can't help it We sat in the exam seats, not at the same table, so I had to turn my head and look at the books of the classmates behind us.

Everyone thinks that wearing glasses symbolizes wisdom, but only those who wear glasses will know the distress of wearing glasses. Hey! It's all because you didn't protect your eyes. Unfortunately, there is no regret medicine in the world!

I have had an indissoluble bond with books since I was a child. When I was one year old, I first caught a book. Now, I can't stay without books!

Every time I go out, I go to the library and bookstore to have a good look for a while; At home, I will read a few pages when I have time.

On this day, I put away a book and sneaked into the toilet. I am happy while reading it: hey, hey, this book is almost finished. Which book should I read after reading it? Just when I was proud, "Sensen!" Mother suddenly stood in front of her. I exclaimed, "Mom, you scared me to death!" " My mother said angrily, "I'm worried about you in this dim light." ... "Before my mother finished, I covered my ears and escaped from the toilet.

A few days later, I gloated with my cousin to check my eyesight. When I arrived at the eye hospital, my mother first threw herself into the optometry room. After the doctor checked, he told his mother, "The child is nearsighted and needs glasses." I suddenly silly, "oh, my god! Why can a child prodigy who can recite ancient poems at the age of one and a half and read newspapers at the age of three suffer from myopia? It's so unfair! " I can't help screaming at the sky. But there was nothing I could do, so I had to ask my mother to drag me into the glasses area. She also said angrily, "No more reading, watching TV and playing computer!" " "I'm very upset. Television has nothing to do with computers, but books are my lifeblood! But on second thought, my mother is also good for me!

Wearing glasses makes me feel uncomfortable, alas! I can't take it off any more. It's ugly. I thought about it. Tears fell from my eyes. The doctor and aunt looked at my grievance, pulled me over and whispered, "Stop crying, little friend!"! Pay attention to protect your eyes in the future. Aunt will teach you some methods. Go home and stick to it, and you can take off your glasses next year. " Mother's tone softened, "Sensen, listen to your aunt, don't cry.

"At this moment, I just smile through tears.

When I got home, I recalled the scene of this decade. I used to be too careless about eye hygiene. Lying, lying, eating, sleeping, riding, walking, always holding a book. Can the eyes not be nearsighted? In the future, I will get rid of all the bad habits, protect my eyes according to the methods taught by my aunt and doctors, and also teach my classmates these methods so that they can have bright and healthy eyes like me.

6 5438+04 At 8: 30am on August 8th, the social practice activity of "Keshi Cup" Dahe Daily reporter with the theme of "preventing and controlling myopia and caring for growth" was held in the conference center of Century Star Express Hotel.

Dahe newspaper small reporter group was established in 20XX, with a history of 6 years. Today, 7 1 students joined the small press corps, and now there are thousands of small press corps, which is exciting. Sister dahe baolan told reporters how to write news. She said humorously, "It's not news that dogs bite, but it's news that people bite dogs!" She also encourages young journalists: be a young journalist today and achieve great things tomorrow!

Subsequently, Liu Jiaoshou, a provincial ophthalmologist, began a lecture on "Prevention and Control of Myopia, Caring for Growth". From Liu Jiaoshou's humorous report, we know that the incidence of myopia in China ranks first in the world, and the population of myopia in China reaches 300-400 million. The population of Henan Province is 1 100 million, the nearsighted population is 5 million, and the nearsighted population of Zhengzhou City is nearly 1 10000. The myopia rate of primary school students in China reached 3 1.67%, junior high school students reached 58.07%, senior high school students reached 76.02% and college students reached 82.68%. Scientists have proved through a large number of experiments that teenagers' myopia is mainly caused by poor sitting posture and excessive use of eyes. Scientists also pointed out that myopia has a certain relationship with heredity: parents are not nearsighted, and the myopia rate of children reaches 20%; Both parents have myopia, and the child's myopia rate reaches 50%; Both parents are nearsighted, and the myopia rate of children reaches 70%. Prevention and control of myopia has attracted the attention of the whole society.

Liu Jiaoshou also told us that myopia is not only preventable and controllable, but also treatable. At present, the better treatment is corneal surgery, that is, laser excimer surgery, but it must wait until 18 years old. Another way is to wear a "orthokeratology mirror" at night, and your vision can reach normal during the day.

The eyes are the windows to the soul. Let's take action: prevent and control myopia and protect our eyes!

As the saying goes, "the eyes are the windows to the soul." This shows how important the eyes are. However, with the process of computer, TV and other high-tech electronic products entering the family, the myopia rate of students has gradually increased. In other words, most students are covered with dust.

As a nearsighted student, what I see after getting up every morning is no longer a bright and clear world. If I don't wear a mirror, I feel like living in fog.

After I was nearsighted, I was very entangled in the question of whether to wear a mirror: I was afraid that my classmates would call me a four-eyed girl if I wore a mirror, and I was afraid that I couldn't see the blackboard clearly without wearing it. Finally, I also became a member of "seeing the world through the glass".

Maybe only people who wear glasses can understand people who wear glasses. Actually, I thought it was nothing, but later I found it inconvenient to bring a mirror. In cold weather, the mirror will frost. Besides, if you forget to bring a mirror, you can't see anything clearly.

Some students may think that since wearing glasses is so terrible, I won't wear glasses for myopia. If you think so, you are wrong. Without a mirror, your education will soar all the way. Eventually become a high number of prisoners, so I'm afraid this is not what we want! Therefore, it is very important to protect our eyes.

Some people must think I'm making a mountain out of a molehill. When I grow up, I just need a lens removal operation. Actually, it's not that simple. If you want to do this operation, age is a problem first. You must be at least 18 years old. I'm afraid we have to wait a long time. Secondly, the cornea should also reach a certain thickness; And if one of your eyes doesn't meet the requirements during the examination, then you can't have surgery.

Through my "excellent example", everyone must understand how important vision is to us. I have summarized the following methods for your reference:

1, watch TV and play computer for an hour and give your eyes a vacation;

2, eat more carrots and other foods that can protect your eyes;

3. Read more green things and write less in the dark;

If you pay attention to eye hygiene now.

Myopia is not terrible. You can go to the hospital regularly and change the mirror as needed. Let's protect our eyes together and have a bright future!

A composition for preventing myopia in junior middle school

Why are there so many nearsighted students in our class? Do you know how much trouble they are in? For example, Zhuo Zhenyu squinted almost every time he looked at the blackboard, and once he left his glasses on the playground. When everyone started doing their homework, he found that his glasses had dropped, so instead of writing, he raised his hand and asked the teacher for leave to go to the playground to get his glasses. You said, you have to run to the playground to get it. What a bother!

So how to prevent myopia?

First of all, form a good habit of using your eyes. Keep a good distance of "one punch, one foot, one inch". After reading and doing homework for 45 minutes, you should have a rest, look ahead and look far away.

Second, be a good boy who is not picky about food. Eat more green vegetables, carrots, egg yolks and corn, drink more pure milk and eat more fish, seafood and animal offal. Eat less sweets and fried foods.

Third, do outdoor activities for two hours every day to supplement natural light. The retina absorbs natural light and converts it into dopamine to supplement the nutrition of the retina.

Four, build a good vision development file, review it regularly every two to three months, and do a good job in early detection, early intervention and early prevention.

If you have bright eyes, you can see beautiful scenery and colorful world. To prevent myopia, start with me.
