Recently, according to a survey conducted by China, the United States and Australia to prevent myopia in children, the number of people with myopia in China has reached nearly 4 million, ranking first in the world, and the incidence of myopia has reached 1.5 times the world average, and the incidence of myopia among teenagers is as high as 5% to 6%. The number of nearsightedness is increasing year by year, which has become an important problem affecting the health of our people. Please use your eyes scientifically, Ye Junjie. Whenever I see you looking at distant objects, I always have to squint my eyes for a long time without seeing them clearly. As you are the tallest in the class, the teacher arranged your seat in the last row. But your eyesight is already very poor, and if it goes on like this, it will affect your study. You can hardly see the words on the blackboard. I think there should be some factors in your inattention in class!
In order to restore your eyesight and make progress in your study, please keep enough sleep! Listening to my father, keeping enough sleep is an important factor to eliminate fatigue and restore my main work and study ability. Because the muscles of the eyes are most relaxed during sleep, it is the easiest to eliminate fatigue, and it is also essential to ensure good health. The diet structure should also be reasonable. The research report shows that increasing protein in the diet and reducing the supply of carbohydrates can reduce or stop the increase of myopia in adolescents with genetic background. Therefore, in order to avoid the increase of myopia, you should take good care of your mouth, try to eat less candy or high-sugar foods, and eat more eggs or foods with high protein content.
please use your eyes scientifically. The eyes are the windows of the soul. If the windows are broken, they should be repaired in time. Don't wait until they are terminally ill to save them. How serious it will be if the mind has no windows! 2. Please use your eyes scientifically

In the fifth grade of primary school, there are more and more students wearing glasses in our class. For this reason, Miss Li was very anxious, so she held a seminar in the class to ask everyone to express their views on the issue of "scientific use of eyes". The discussion began and the students were in full swing.
Some students introduced the causes of myopia, some students talked about their troubles after wearing glasses, and some students talked about good ways to prevent myopia. Xu ruijing said: "eat more fruits and vegetables, and eat more things containing vitamin c, and don't be picky about food."
We should also pay attention to a reasonable diet and maintain a balanced nutrition. " Wu Yue said: "When reading and writing, the light should be moderate. Too dim light can easily make the eyes tense and feel tired, which is very harmful to the eyes in weak light. It is recommended to use soft lighting to provide contrast between light and dark."
"TV, computer and mobile phone all have radiation, so try to avoid contact." Li Xinyu rushed to say.
"When reading and writing, the posture should be correct, and it should not exceed one hour. Don't hunch over or read on your desk, let alone lie on the bed and read sideways. The distance between eyes and books should be kept at 3-35 cm, the distance between body and textbooks should be about 1 cm, and the angle between books and desks should be kept at 3-45 cm. "
Du Haoze quickly added. Liu Yu said: "If you feel tired after finishing your homework, you can roll your eyes or look at the distant trees in the window, and the nervous nerves will feel relaxed and the fatigue of your eyes will disappear."
... Teacher Li said, "Everyone talked very well. In the future, we must use our eyes scientifically and take good care of our eyes, which are the windows of the soul." . 4. Use your eyes scientifically and grow up healthily. Can you help me write this composition before 5 o'clock? I will give you extra points
I will give you a reference
How important it is for us primary school students to establish the idea of scientific like eyes's eye protection. Eyes can be mainly divided into three parts, namely, eye attachment, eyeball and vision. Among them, the sclera can protect the eyes, so it got an nickname-called "camera shell". There is also a "tear container", which is responsible for making people cry, so it is called-eye cleaner. The eye is like a camera, and each part has different functions, for example, the transparent and powerful cornea and lens are equivalent to the lens; The pupil that can be narrowed or widened according to the intensity of light is equivalent to the aperture; The choroid, which is rich in pigment and has shading effect, is equivalent to a black box; Photosensitive tissue retina is equivalent to photosensitive film. The working process of the eyes is roughly like this; Various objects in nature reflect light with different brightness under the irradiation of light. These light rays are focused on the retina through the refraction of cornea, lens and other structures, and the photosensitive cells on the retina produce a series of electrochemical changes, which turn light into nerve impulses and transmit them to the visual center of the brain through visual pathways to complete visual functions. In the above process, the pupil can adjust the light entering the eyeball; The lens also ensures that the light is accurately focused on the retina through adjustment, thus obtaining a complete and clear object image. It can be seen that it is a complex and delicate process for the eyes to complete a visual action. If any detail is blocked, it is impossible to obtain a correct "photo". No matter how good the function of the eyes is, it is useless not to protect them. We must observe the three dos and don 'ts: First, pay attention to eye hygiene. Reading or using the computer should not be too long. Take a break for 1-15 minutes every 3-4 minutes, look far away and relax your eyes. No more than 6 hours in front of the computer every day. Don't read in a dark place. Such as: bathroom. The bathroom is dark and the light source is unscientific, which is harmful to the eyes. Some people are reading in bed, and poor posture will increase the burden on their eyes. Second, we should pay attention to eye exercises. Doing eye exercises can make blood flow smoothly, relax muscles and relieve fatigue. In ball games, when the eyeball follows the target, the ciliary muscle relaxes and contracts, which improves the blood perfusion of the eye and promotes the metabolism of the eye. Second, don't place eye drops regularly. Your eyes will feel very comfortable when you first use it. If you use it for a long time, it may lead to glaucoma, visual impairment or even blindness. No surgery or medicine can save it, not to scare you. Third, we should eat more food to protect our eyes and supplement nutrition. Vitamin A and carotene are the main nutrients for normal metabolism of human body. Pay attention to replenish water and eat more soy products, fish, milk, vegetables, tomatoes and fresh fruits to protect your eyes. Third, don't use inferior sunglasses. Inferior sunglasses, the performance of blocking ultraviolet rays is not strong, and the coating film is easy to be damaged, which seriously reduces the transmittance. The eyes are like seeing things in a dark room. At this time, the pupils will become larger, and the residual ultraviolet rays will be injected into the eyes in large quantities, which will damage the eyes. Don't let fashionable sunglasses become "eye killers", choose good sunglasses. 5. To prevent myopia, 45 words of scientific eye composition should be original and urgent < P > To prevent myopia, we should pay attention to the following points: ① To develop the correct posture of children reading and writing, the distance between eyes and books should be about 3 cm.
② When reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as to avoid the shadow of the hand obstructing the line of sight. (3) reading time should not be too long, every 4~5 minutes, should rest for 1~15 minutes, close your eyes or look into the distance for a few minutes or do eye exercises to prevent eye fatigue.
④ Don't read books and newspapers whose handwriting is too small or fuzzy, and don't write too small. ⑤ Educate children to correct unreasonable eye habits, such as lying on the table, reading or writing with a crooked head, reading in bed, reading at meals, reading in strong light or dim street lamps and moonlight, reading in a moving car and walking, etc. These bad habits will make the eyes excessively tired and reduce the acuity of vision.
Preventive measures should also be taken from the following aspects: (1) Prohibition of consanguineous marriage. (2) Pay attention to eye care.
prevention of myopia advocates an early word, that is, it should start at school-age children. (1) schools and parents should pay special attention to children's learning lighting to meet the requirements (5~1 meters candle), specifically, if a 25-watt ordinary light bulb is used, the illumination at a distance of half a meter is about 5 meters candle, and so on.
② prevent overuse of eyes, that is, don't make the internal and external muscles of eyes excessively tired or in a state of tension for a long time. ③ Strengthen eyesight training and insist on eye exercises.
④ prevent TV myopia. (3) Strengthening physical exercise and improving physical fitness can reduce and slow down the occurrence of myopia, especially outdoor sports.
It is also one of the best health care methods for eyes to let children overlook the countryside with fresh air and broad vision and admire the mountains and rivers of the motherland. (4) Pay attention to nutritional supplements, especially vitamin B and mineral supplements, because they are necessary for eye development and functional progress.
Can prenatal and postnatal care reduce myopia in children? It is reasonable for children to blame their parents for being nearsighted. For a long time, many surveys have confirmed that the occurrence of myopia has a certain familial nature. Parents are nearsighted, children suffer from myopia more, parents are not nearsighted, children suffer from myopia less, one parent suffers from myopia, and children suffer from myopia between the above two.
Therefore, children's myopia is closely related to their parents. There are many children's eye deformities, strabismus, ametropia, amblyopia, etc. due to improper parents' marriage and poor pregnancy. Some parents run around for the diagnosis and treatment of their children's eye diseases, silently suffering from their inner pain and paying unlimited prices; There are also a few parents who relentlessly give up treatment for their children without remorse. What's more, they apply for another birth because of their children's eye diseases ... We really feel sad and guilty for these ignorant, ignorant and heartless parents, and we care more for those children who are victims.
Here, we should warn these parents, to know now, why at the beginning! In order to benefit future generations, eugenics is irresistible. How to prevent myopia among teenagers should pay attention to the following points: ① To cultivate the correct posture of children reading and writing, the distance between eyes and books should be about 3 cm.
② When reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as to avoid the shadow of the hand obstructing the line of sight.
