2. What is the information about liking eye protection manuscripts?
Such as eye protection manuscript information
People often say that the eyes are spiritual.
Windows. The brighter the window, the more wonderful the world we see. If the windows are covered with dust, we can't see the beautiful world clearly. However, many people do not pay attention to protecting their eyes, leading to myopia or amblyopia, which brings a lot of inconvenience to study and life. If we don't protect our eyes and cause blindness, then this window of the soul will be closed forever. The formation of myopia has a lot to do with personal habits. Some students spend too much time playing computer and watching TV. Some students write incorrectly, and their eyes are too close to the book. Some students are picky eaters, which leads to insufficient nutrition in their eyes. Some students don't do eye exercises carefully and can't play a health care role. There are many bad habits that can easily lead to myopia or amblyopia. Come to think of it, I have such a bad habit. Every time I finish my homework, I always want to turn on the computer and play for a while. The result is addiction. Sometimes my mother invites me to dinner, and I don't want to go. I am always picky about food when I eat. Don't eat vegetables with meat, and don't drink soup with vegetables. These bad habits are often criticized by my parents and often remind me to protect my eyes. Take care of your eyes and stay away from myopia.
3. How to write something that likes eye handwritten newspaper?
The content of like eyes handwritten newspaper can be described from three aspects: common sense of like eyes, resting eyes and preventing eye trauma.
1, like eye knowledge
The eye is one of the most important sensory organs of human body, and 90% of the external information comes from the eye. It is everyone's wish to have healthy and bright eyes. Primary school students who entered the school gate began the most basic and longest study life, and the burden on their eyes began to increase. Learning how to care for your eyes is a common sense for every student.
Step 2 pay attention to rest
People's eyes need to adjust the ciliary muscles in their eyes when reading books, watching computers and other close objects. After a long time, you will be tired and cause myopia. You should take a proper rest. A 10 minute rest after 45 minutes of each class is not only a rest for the brain, but also a rest for the eyes. We should pay attention to the distance and relax our eyes. We should also do eye exercises to help our eyes relax.
3. Prevent eye trauma
Pupils are active and active, which is the prone age of eye trauma. Pay attention to safety and don't play with sharp objects, such as awls, scissors, needles, bone needles, etc. Slingshots and toys that can eject rocks should also be banned. Children should protect their eyes. When making toys and aviation models, more attention should be paid to prevent eye injury when using scissors, awls or cutting lines with scissors.
Extended data:
Teenagers' eyes have strong adjustment ability. When the distance between the book and the eyes reaches 7- 10 cm, you can still see clearly. But if they often read and write at this distance, the adjustment of their eyes will be extremely tense, thus forming refractive (accommodative) myopia, that is, pseudomyopia.
If the ciliary muscle can't flex flexibly due to excessive adjustment for a long time, and the eyeball tissue of teenagers is delicate, the eyeball wall will gradually lengthen under pressure, and the anterior and posterior axes of the eyeball will become longer. If it exceeds the normal value, axial myopia, the so-called true myopia, is formed.
4. Common sense such as eyes
1. When you start to learn to write with a pen, you should learn how to hold the pen, keep the distance between your eyes and the book, and pay attention to your child's sitting posture.
2. Avoid eyes being exposed to the sun for a long time. When going out to play, take a walk or ride a bike around noon with strong sunshine, even if it is only for a few minutes, you must wear a sun hat to protect your eyes from direct sunlight.
3. Try to avoid watching TV, computer and playing mobile phone for a long time. Don't read or play with your mobile phone while walking or riding a bike. This is not only dangerous, but also harmful to our eyes. If you don't pay attention, you may suffer from myopia at some point.
4. Avoid contact with allergic substances. In allergic season, some students love to shed tears, which is probably caused by allergies. Students with allergic eyes need to wear goggles or goggles when going out to avoid contact with pollen or other allergic substances.
5. Take the initiative to exercise. Children shouldn't stay indoors all the time. They can play games, take a walk, see the distant view and so on. Rest between classes relaxes the muscles that regulate the eyes and relieves visual fatigue. You can climb mountains, play ball, run and swim outdoors on holidays, which are all ways to relieve eye fatigue. Pay more attention to eye rest.
6, pay attention to nutritional supplements. Nutritional deficiency caused by improper diet is also one of the important reasons for the occurrence and development of myopia in children. You shouldn't be picky about food. You should eat more carrots, tomatoes, bean sprouts, oranges, grapes, oranges, red dates and other vegetables and fruits, which is good for preventing myopia.

Take care of your eyes and handwritten newspaper materials.
The World Health Organization (WHO) estimates that at least 35 million people in the world need low-vision care services due to refractive errors.
Myopia is the most common ametropia, and juvenile myopia is the most common. Myopia not only damages vision, leads to poor vision, but also leads to blindness.
June 6th is National Eye Love Day. On the eve of the 1 1 National Eye-Love Day, a letter from readers caught our attention. In this article, an "old nearsighted" and "little blue" who have worn glasses for 44 years tell their experiences of using a magnifying glass in their early years, which triggered many associations and appeals.
Is there any basis for this method? We forwarded the article to Gao Jiansheng, chief physician of the Eye Hospital of Chinese Academy of Traditional Chinese Medicine and chairman of the Ophthalmology Branch of Chinese Academy of Traditional Chinese Medicine. Gao Jiansheng believes that the article "has very important practical significance".
At the same time, their articles are published in the hope that readers will be inspired by them, and more hope that relevant social departments will take action to contribute to "protecting eyesight and preventing myopia". Can you use a magnifying glass to prevent myopia and learn to write? Among the methods to prevent and treat pseudomyopia, there is a kind of "fog therapy".
Under the guidance of an optometrist, wearing a pair of glasses of about+1.50 when reading and writing can reduce the adjustment force of rectus muscle and the * * * force of extraocular muscle, so as to read books and newspapers clearly. Now, this method is applied to primary school students in some areas.
This is the same as Comrade Xiaolan unconsciously reading with a magnifying glass in front of her eyes, which can reduce visual fatigue and prolong reading time. For people with low vision, specialized hospitals also use binoculars to help improve their reading ability.
Writers and people who often use computers, especially those with high myopia, can try Comrade Xiao Lan's method. There are many reasons for the prevention and treatment of juvenile true myopia, but excluding congenital or hereditary factors, pseudomyopia is mainly caused by developing bad reading habits in preschool or primary school, including low pen, reading and writing distance less than 30 cm, reading and writing for a long time and so on.
If the bad reading and writing posture is not corrected in time and the corresponding treatment is carried out under the guidance of a doctor, after a period of time, pseudomyopia can be transformed into true myopia. True myopia is due to the over-regulation of flexor muscles and long-term spasm, which makes the eyeball change from normal spherical to oval, and the layers of the eyeball wall become thinner accordingly.
At present, there is no effective method, whether it is instruments or drugs, to return the oval eyeball to a regular sphere. Therefore, the propaganda of myopia treatment instruments and drugs sold in the market is vague in concept and lacks scientific basis.
However, true myopia can be prevented, and the key lies in actively treating pseudomyopia and blocking its development to true myopia. Surgical treatment should be cautious. Excimer laser treatment of true myopia is a high-tech treatment method, which has many advantages and is widely known.
From the optical principle, the operation is completed by destroying a part of the normal cornea, just like putting a pair of contact myopia glasses on the patient, which has no therapeutic effect on the ellipse of the eyeball and the corresponding fundus deformation of myopia. Because there may be some complications, it needs to be treated with caution.
1. Watch the computer for an hour, rest for ten minutes, and close your eyes to see the distant scenery. 2. Keep a certain distance from the computer, not too close, and the length of one arm is appropriate.
3. Eyes like cold and fear heat. When you feel tired, you can often wash your eyes with cold water. 4. Do eye exercises regularly every day.
5. When watching the computer, you can bring a pair of suitable reading glasses to see the screen clearly, which can relieve visual fatigue. The above methods are very important in persistence, and only long-term persistence will have an effect. Friends who care for their eyes can refer to it.
6. Little is known about similar eyes
First, increase the reading distance.
The greater the reading distance, the smaller the adjustment force, and vice versa. The greater the adjustment, the stronger the effect of stimulating true myopia. The distance between the eyes and the book 100 cm requires 300-degree adjustment; 20 cm away from the book needs 500-degree adjustment, so it is very good to develop the habit of reading at a distance, which is good for protecting your eyesight. In addition, wear a sight distance amplifier. According to the principle of light reflection, the sight distance amplifier makes the light turn two bends between the book and the eyes to extend the sight distance, but the writing distance does not extend. Its disadvantage is that the image formed in the eyes is reduced (because the object distance is inversely proportional to the image growth).
Second, see far.
Go up and see the distance between classes or other possible situations. In hyperopia, the distance between the object and the big eyes is small, and the image of retina is not clear before imaging in myopia. If it is not clear, it will force the eyes to relax, and pseudomyopia will be fine. Therefore, instead of playing video games after class, students can fly kites, play model planes, look at the sky at night and count the stars, which can increase the time and distance of concentration and prevent myopia.
Although hyperopia can prevent myopia, students have no time to look far, and short-term hyperopia can't change the contrast between hyperopia and myopia, which is of no help. Therefore, to prevent myopia, only three pairs of glasses are needed to change the geometric characteristics of eyeliner and change reading into hyperopia. Reading books every day is equivalent to hyperopia every day. Putting prevention and treatment in the learning process is the best way to prevent students from myopia.
Third, pay attention to transforming the living environment.
Hang more big mirrors indoors, especially for students living in flat rooms. The bathroom and kitchen are indoors, so there are fewer opportunities to broaden your horizons. If the wall is a mirror, the line of sight will not be blocked. If a wall is a mirror, a house 3 meters wide becomes 6 meters. If all four walls are mirrors, living indoors also has the effect of being in the wilderness, which is very beneficial to the eyes. Physical education class wants to shoot more arrows. Watch less TV, because TV is close to your eyes, and you can sit in the far row and watch movies instead.

Look forward to your participation! How to find children's abnormal vision as soon as possible? Chu Renyuan, Key Laboratory of Myopia, Ministry of Health, Affiliated Eye, Otolaryngology Hospital of Fudan University, for growing children, if parents pay attention, they can catch whether they have vision problems from their usual performance. For example, when you find a child squinting at things; When children look at things, their eyes are not in the same parallel position; Or let the children see some interesting patterns and cover one of their eyes with their hands to see if they can continue to play normally.
Myopia, the most common eye disease among teenagers, can also be found through careful observation. For example, children are vague and don't like outdoor activities; Reading for a long time can easily cause fatigue, photophobia, tears, headache and dizziness. When watching TV and playing computer, I am used to narrowing my eyes and leaning forward. Unexplained academic performance decline and so on.
Once you find that your child has eye problems, you should go to the hospital for further detailed examination in time to determine the real cause of eye diseases. The earlier some congenital eye diseases are found, the better the treatment effect.
However, if adolescent myopia is diagnosed as myopia after examination, the main treatment is glasses. As for the role of drug therapy, many drugs are still under study, and the most promising drugs are M receptor blockers, such as atropine.
However, when atropine is used to treat myopia, it has the side effects of accommodation disorder and mydriasis, so its clinical application is limited. In addition, there is another drug, pirenzepine (still under development), called selective M 1 receptor blocker, which can overcome some side effects of atropine. At present, the eye drops of Xinliuding (raceanisodamine) on the market also have a certain selective blocking effect on M receptor, and its blocking effect on M 1 receptor is similar to that of atropine, but its side effects such as accommodation disorder and mydriasis are far less than that of atropine.
Of course, to stay away from myopia, it is more important to develop correct eye habits, arrange a good work and rest system, pay attention to the combination of work and rest, strengthen exercise, and eat more foods rich in vitamins, such as milk, soybeans, green leafy vegetables, carrots and egg yolks. , are essential foods to ensure eye health. About the author: Chu Renyuan, male, Professor of Ophthalmology, Doctoral Supervisor and Director of Ophthalmology Center, Affiliated Eye, Otolaryngology Hospital of Fudan University.
He is currently the director of the Key Laboratory of Myopia of the Ministry of Health, the chairman of Shanghai Ophthalmology Society and the director of Shanghai Ophthalmology Quality Control Center.

8. What is the common sense of liking eyes?
1, sleep well;
2. Avoid eye fatigue;
3. Eat more food that is good for your eyes;
4, regular inspection, timely correction.
For students, homework in strong sunlight should be avoided during the day; When working at night, keep a room with two light sources: a desk lamp (about 60 watts) on the left hand side, and the other is a ceiling lamp. Desktop can't reflect light.
Food to help protect your eyes.
The first category: foods containing more vitamin A.
Vitamin A has two major effects on human eyes: one is to keep the cornea normal and prevent corneal dryness and degeneration; The second is to enhance the ability to see things in the dark. Animal foods are rich in vitamin A, such as sheep liver, chicken liver, pig liver and milk.
The second category: foods with more carotene.
It is generally found in plant foods, especially in fruits and vegetables containing yellow pigments and orange pigments. Carrots, yellow corn, pumpkins, green vegetables, green beans, tomatoes and apricots. Because carotene in plants can only be absorbed by human body with the help of fat, it is best to use oil when eating, or add some sesame oil when cold.
9. Like the knowledge of eye protection.
In daily life, if you know some knowledge about eye hygiene, your eyes will never be exhausted. The following is a common and fairly simple common sense of eye hygiene for daily use.
1, the distance between people and TV should be more than 5 times or more than 3 meters of the diagonal length of the screen.
2. There is ambient lighting when watching TV. 3. Play less video games to avoid indulging in surfing the Internet.
4. When reading and writing, the light should be bright, soft and stable.
5. Don't write words that are too small and too dense, so as not to look too close and increase the adjustment of your eyes. 6. Keep the writing distance 30 ~ 35cm.
7. Don't study for a long time, 0.5~ 1 hour is appropriate to prevent visual fatigue. 8. Do eye exercises every day to improve eye blood circulation and regulation. 9. Insist on physical exercise, do more outdoor activities 10, and arrange work and rest time reasonably.
1 1, ensure full and comprehensive nutrition, correct partial eclipse, eat more fruits and various vegetables 12, and wear qualified and suitable glasses for ametropia.
13, people with high myopia should not do strenuous activities to avoid rage, so as to avoid retinal detachment like eyes. Eye protection tips (computer)
Friends who have been in contact with computers for a long time often feel tired eyes. If you follow the following steps to check, there will be great changes.
Step 1: Adjust the computer screen.
Adjusting the contrast and brightness of the screen is helpful to reduce the eye problems caused by the computer, because the screen flashing too fast or too slow will cause eye discomfort.
Screen scanning frequency should be greater than 60 times per second. If the scanning frequency is too slow, it will cause the screen to flicker and further cause eye discomfort.
Suggestions for improvement: Adjust the contrast and brightness of the computer screen to keep the scanning frequency greater than 60 times per second.
Step 2: Adjust the eye position.
The average person's normal reading angle is about 40 degrees. Generally speaking, looking directly at the computer screen is an unnatural angle, so it is easy to cause fatigue, sore eyes and even headaches.
Suggestions for improvement: Adjust the height of the seat and the angle of the computer screen so that the center of the screen is between 7 degrees and 10 degrees below the eyes.
Step 3: Avoid reflection.
In the light part, the principle is to see clearly and comfortably. Also pay attention to the light, fluorescent lamp, sunlight, reflective surface and bright body, and pay attention to the position of the screen to ensure that you can't see the reflection.
Generally speaking, indoor light is three times brighter than the screen. Step 4: 3B vision care Formula.
While adjusting the computer, we should also pay attention to the common sense of self-protection. As long as you follow the following "3B" eye protection methods, your eyes will be bright.
Blink: blink more.
Staring at the computer for a long time will reduce the blink of an eye and cause dry eyes, so usually
Blink more and keep your eyes moist.
Breathe: take a deep breath
Staring at the computer screen for a long time often leads to a temporary stop of breathing, so keep breathing smoothly and relax.
Rest: rest
Every time you work or read 10 minutes, look far 10 seconds to relax your eyes. Every time you work or read 1 hour, you should rest for 5 minutes, and you can do some eye exercises to rest your eyes. You should get up every 2-3 hours to have a cup of tea and exercise after work or reading.
Common sense of eye protection (dry eye)
Do you often have this situation: your eyes are stinging, itchy, dry and sandy, and sometimes you can't open your eyes in the morning because of too much mucus, and so on. Then it is very likely that you are suffering from "modern dry eye syndrome", also known as dry keratitis, which refers to a series of eye symptoms caused by the pathological changes of the tear film of the eye due to various reasons, which makes the cornea and conjunctiva not moist normally. With the modernization of office equipment and household appliances, and the change of people's diet structure, there are more and more dry eyes, from primary and middle school students to middle-aged and elderly people.
The main causes of dry eye are as follows: 1) wearing contact lenses 2) not paying attention to eye hygiene.
3) Reduce the number of blinks when working, studying and driving 4) Dry air 5) Dust pollution 6) Use sedatives.
For these reasons, the function of tear film will be affected, and the cornea and conjunctiva will lose moisture and smoothness, resulting in conjunctiva dryness. If not treated in time, it may cause corneal opacity, ulcer and even blindness.
How to prevent dry eye in daily life? People who use their eyes too much should pay attention to eye hygiene, blink more, close their eyes, overlook, do eye exercises to relieve eye fatigue, eat more foods rich in vitamin A, and go to the hospital for examination in time if the eyes have abnormal symptoms such as dryness and foreign body sensation. Don't take medicine by yourself, so as not to delay your illness.
How to prevent dry eye, we should pay attention to the following points: 1) have a normal lifestyle, get enough sleep and don't stay up late;
2) Balanced diet, no partial eclipse; Eat more fruits and vegetables containing vitamins A, C and E, and eat less fried food;
3) Let your eyes rest adequately, avoid long-term use of eyes and excessive fatigue, and pay attention to the number of blinks;
4) Pay attention to the cleanliness of eyelids and eyelashes when washing your face. Hot compress with hot towel can reduce fatigue and increase tear secretion;
5) Don't wear contact lenses for too long, and take them off if you feel uncomfortable;
6) If you have eye discomfort, please consult an ophthalmologist for treatment; Never buy Chinese patent medicines for long-term use.
10. How to draw a handwritten newspaper like eyes to protect your eyes?
1) Correct reading and writing posture: When reading or writing, the best distance between eyes and books is about one foot. To this end, the height of tables and chairs should be properly matched, and high chairs and low tables or low chairs and high tables are not conducive to the health of eyes. Don't tilt your head when writing, and don't read books or newspapers when walking, riding or taking a boat.
(2) Reading and writing time should be appropriate: reading, writing, drawing and other eye time is too long, which is easy to make eye muscles tired and lead to myopia. Therefore, every hour of reading and writing, you should go outdoors for 10 minutes, which is an effective way to eliminate eye muscle fatigue and prevent myopia.
(3) Adequate light: Adequate light is an important aspect of maintaining normal vision. You shouldn't read or write in too dim light, such as dusk and darkroom. When reading and writing at night, the lights should not be too dim, shaking or dazzling. The light should come from the left front to avoid shadows blocking the line of sight. Do not read or write in strong light (such as sunlight or dazzling light) or in the shadow of flowers to reduce the adjustment burden of intraocular lens and ciliary body.
(4) Don't watch TV for too long: TV is a dynamic picture, and watching it for too long is most likely to lead to eye muscle fatigue and myopia. Therefore, watching TV should not be too long, generally should be controlled within 2 hours, and rest for at least 5 minutes every 30 minutes to give your eyes a rest. The distance to watch TV should be appropriate, generally 2 meters away, and the angle should not exceed 45 degrees. In the room watching TV, there should be a certain brightness of the lights. You can turn on a small light, but don't direct the light at the screen or eyes. It's best to put it in the back or next to it. When debugging the TV, the jumping picture on the TV screen hurts your eyes. Close your eyes to avoid * * *.
2. Insist on doing eye exercises. Doing eye exercises is an effective way to prevent myopia and should be adhered to every day. If you're not a scholar, you can take eye risks lightly or close your eyes to help you recover from eye muscle fatigue.
3. In life, we should avoid strengthening physical exercise, advocate outdoor activities, often bask in the sun and breathe fresh air. Life should be regular, go to bed early and get up early, and keep enough sleep and proper rest. Pay attention to nutrition, don't be partial to food, don't eat snacks, eat vegetarian and vitamin-rich foods and calcium-supplemented foods, such as pork liver, milk and eggs.
4. Check your eyesight regularly. Check your eyesight regularly and adjust your study and maintenance according to your eyesight.
5. Preventive prescription cassia seed decoction, instead of tea, is often effective.
