Methods of preventing myopia in primary school students
Students, at present, the problem of juvenile myopia has been widely concerned by the society. The relevant departments of the state held a video conference on myopia prevention and control, and various localities also took measures to prevent myopia among teenagers. Let's take a look at the prevention methods of myopia in primary school students. The pressure of competition in modern society is increasing, and the schoolwork burden of primary school students is getting heavier and heavier, which leads to more and more myopia and younger age, which is a problem that parents and schools are very worried about. How do primary school students prevent myopia? Here is to introduce the prevention of myopia in primary school students:
(1) Pay attention to choosing listening rather than reading in learning to reduce the load on your eyes. (2) Avoid continuous close-ups for too long. Pay attention to reading, writing and computer operation. After reading continuously for nearly 40 minutes, take a rest and look at the distance 10- 15 minutes. Try to control the cumulative close-up time every day, preferably no more than 6 hours. (3) Pay attention to improving the environment that needs to be looked at for a long time. There should be enough light in the classroom, the desktop and blackboard should not reflect too much light, and the curtains should be closed. It is advisable to sit anywhere in the classroom and look out of the window, changing seats regularly; At home, children's desks should be placed outside the window where there is no obstruction, and the desk lamps should be placed in front of the left, with soft light, such as incandescent lamps, preferably between 25-40W, and the position should not be direct to the eyes. (4) correct bad posture. When reading and operating a computer, we should pay attention to keeping the distance between eyes and books at about 33 cm, the distance between eyes and a computer screen of 35 cm size should not be less than 60 cm, and the distance between eyes and a computer screen of 38 cm size should not be less than 70 cm. Keep a correct sitting posture. Don't read while lying down or watch while walking. (5) If your eyes are dry and red when you have been looking closely, there are
Burning sensation or foreign body sensation, heavy eyelids, blurred vision, and even swelling, pain or headache of the eyes all indicate that the symptoms of visual fatigue have appeared. You should immediately stop watching at close range and do eye exercises. You can also use hot and wet towels to press your eyes to relieve visual fatigue. If there is no obvious improvement after the above treatment, you need to go to the hospital to see an ophthalmologist. (6) Try to play less games that need to be watched for a long time. In modern cities, students' games are mostly indoor entertainment, such as personal toys, game machines, computers, televisions and so on. And there are few opportunities to get away from the nearby environment every day. Therefore, students should change the way of playing games and do more outdoor activities.

Chapter Two: Language of Eyes and Glasses
About two thousand years ago, there was a tyrant in the Roman Empire named Wen Fen. He is very cruel and especially likes to make fun of the slaves who kill each other in the arena. However, his eyes are not good, and he can't see those cruel scenes clearly from the stands. He ordered the craftsman to sharpen a pair of glasses so that he could see the distance clearly. A clever craftsman grinds a concave lens for him with emeralds. Although it is rough, if you put it close to your eyes, you can see things in the distance much more clearly. This monocle dedicated to the Roman emperor is the ancestor of myopia.
Later, whether at home or abroad, myopia glasses and hyperopia glasses made of crystal appeared one after another. He Kang, a British scholar, wrote a book about crystal glasses in the middle of13rd century, explaining that rock crystals were used to grind lenses a long time ago.
So, who invented the glass glasses? Inventors didn't leave their names in the world.
At present, we know that the earliest place to sell glasses is Venice, Italy, about six or seven hundred years ago. At that time, the price of glass was not high, but because it was very scarce, a pair of glass glasses was worth thousands of dollars, and only a few nobles and bureaucrats could enjoy it.
At that time, glasses were not on the bridge of the nose. Some glasses are installed on the brim, and some glasses are installed in a wooden frame, skeleton or iron ring, so you should hold them by hand when you see things; Some people put their glasses on their belts and tie them on their heads when they look at things.
About the end of 16, today's glasses that can be placed on the bridge of the nose appeared. What does glasses have to do with eyes?
In the past, people went to the optical shop to choose glasses, and which pair to wear was better. Craftsmen grind lenses by experience, and there are no strict rules.
/kloc-at the end of 0/6, astronomer Kepler unveiled the secret of the eye. He found that the black eyeball in the eyelid is a raised transparent crystal that can adjust the incoming light. The limbic muscles of the lens have the ability to contract and relax. With the distance of the watched object, the lens can become convex or flat, so that the image of the object falls on the retina just behind the eyeball, making people see the clear object.
However, there is a limit to this contraction and relaxation of the eyeball. Some lenses become very prominent, leading to myopia. You must wear a concave lens to see things in the distance. Some lenses become hyperopia because they are too peaceful. You need to wear a convex lens to see things nearby.
At the beginning of this century, there appeared a scientific method to check the eyesight of eyes, called "optometry". After optometry, find out the right degree and you can get the most suitable glasses.
Chapter 3: Two model essays on World Eye-Love Day.
one
Dear teachers and students:
Good morning everyone.
Today, the topic of my speech here is "Love your eyes and cherish the light". June 6th every year is World Eye-Love Day. We all often say that the eyes are the windows of the soul and an indispensable part of our human body. Imagine that if one day we lose this precious "window of the soul", our eyes will be dark, and we will never see beautiful colors again, but we can only listen to the laughter and laughter of others while playing. Then how gloomy our world will be. How lonely and helpless that feeling is! As Helen Keller wrote in "If Give Me Three Days of Light", she wants to have three days of light to perceive the world and familiarize herself with everything around her. Helen wants to see too many things. Three days of light is just a short moment in life for ordinary people. For Helen, who is blind, this is unimaginable. Similarly, the weakening of vision will also bring a lot of inconvenience to our study and life. At present, according to the preliminary investigation of children's myopia prevention and treatment research projects in China, the United States and Australia, the incidence of myopia in China is 33%, and the number of myopia in China has reached nearly 400 million, which is 22% 1.5 times of the world average. The incidence of myopia among adolescents is as high as 50% to 60%. China is one of the countries with the highest incidence of myopia in the world, and the number of myopes ranks first in the world. Myopia has become an important problem affecting the health of our people.
Pseudomyopia is also a common problem for students. Due to long-term observation of near objects, eye muscle adjustment spasm is caused, and some diopters are still not relaxed during hyperopia, so hyperopia is reduced and myopia is normal. If you suffer from pseudomyopia, if you don't prevent it, your eyes will be in an over-regulated state for a long time. Over time, some pseudomyopia may become true myopia. Pseudomyopia can be treated. It is the fundamental measure to treat pseudomyopia and prevent true myopia by doing everything possible to make it look far and relax its adjustment.
A large number of medical studies have confirmed that with the deepening of myopia, the incidence of various eye diseases will increase significantly, such as macular degeneration, retinal detachment, etc., especially high myopia is more likely to cause the above complications, and severe cases can lead to blindness. Students' myopia will affect the career choice of high-quality talents in China, narrow the choice range of many special majors, and even become the primary factor limiting the health examination major of the senior high school entrance examination. Myopia is different from other high-risk diseases. It is not sudden, but gradual and preventable.
The main causes of myopia:
1 Watch TV too close;
Watching TV for too long;
3. The image density of TV is too deep;
4. Incorrect posture when writing homework;
⑤ Reading in the sun with too strong light;
6 reading in too weak light;
7. Sitting in front of the computer and TV for a long time;
8 unreasonable diet;
9 reading in the carriage
10 genetic factor
1 1 Not doing eye exercises seriously.
Here I want to give you some advice:
1 Sit up straight when reading. When reading or writing, keep your eyes one foot away from the book, your chest one punch away from the desk, and keep your hands.
An inch away from the nib. "
Don't read while riding a bike or walking, and don't read while lying down.
Insist on doing eye exercises twice a day.
Try to surf the internet less or watch other radioactive things. Pay attention to the schedule and don't let your eyes be tired for a long time.
Eyes are the windows of the soul, so we must protect them! Students, let's cultivate our good eye habits from now on. * * * Protect our eyes. I believe that as long as everyone works hard, everyone will have a pair of bright and clear eyes.

Dear teachers and students:
Good Morning, everyone!
Students, do you know what June 6th is? Maybe you don't know yet. June 6th this year is the17th National Eye Care Day. The theme of my speech today is "Protect your eyes like eyes and have bright eyes".
Eyes are the windows of the soul, and everyone has a pair of bright eyes. These eyes can see the colorful world, but now, the clear vision is getting farther and farther away from us. Why is this? This is because many students don't rest with their eyes, wipe their eyes regardless of hygiene, watch TV, use computers, read books and so on. Maybe some students mistakenly think that "I can wear glasses as long as I study well and have poor eyesight." Moreover, wearing glasses is a symbol of knowledge. But real life tells us that wearing glasses will bring a lot of inconvenience to study and life once you suffer from myopia. For example, it is common to take part in sports activities, play basketball or football, break glasses or even hurt your eyes, and go to the hospital for surgery and suture. If you still don't pay attention to eye hygiene when wearing glasses, your eyesight will often decline faster, leading to high myopia and even blindness. Moreover, students with high myopia will be restricted in choosing a major in the future college entrance examination and choosing a job in the future. If you do well in your studies and are turned away from your favorite major just because of myopia, you will regret it all your life.
Eyes can let us know the world and learn knowledge. If we lose our bright eyes, our world will be dark. The prevalence of myopia in China is still rising year by year, and it has now risen to the second place in the world, so students must consciously pay attention to scientific use of eyes in their daily life and study. Below, I would like to give you some suggestions:
1. When reading and writing, keep the distance between your eyes and the book at about 30 cm and keep your posture correct.
2. After writing for 50 minutes, rest for about 10 minutes.
Don't read in places where the light is too strong or too weak.
4. Don't read while walking or riding a bike.
5. Don't read in bed.
6. Insist on doing eye exercises.
Students, do you know that the eyes are the most important organs in human senses? About half of the memory and knowledge in the brain comes from the eyes. Is there any reason not to protect your eyes?
As the saying goes: Rome wasn't built in a day, and it wasn't built in a day, and eye protection didn't happen overnight. It is important to pay attention to eye hygiene and scientific eye use, but it is also necessary to prevent myopia and deepen the degree of myopia.
Graceful mountains and rivers, colorful things, everything needs eyes to observe, classmates, let's protect the eyes of like eyes together and have a pair of bright eyes.
