The formation of myopia mainly comes from physical diseases. Due to short-distance use of eyes and high-intensity use of eyes (computer is a typical state), eye fatigue occurs. If you are in a state of fatigue for a long time and cannot be relieved and adjusted, it will easily lead to myopia. The best choice in the face of myopia is not treatment, but prevention.

Environmental factors: the myopia rate of students remains high, the academic burden is too heavy, and the short-distance eye use time is too long. With the prevalence of electronic game consoles, the popularization of computers and the development of network information, playing video games, surfing the Internet and watching TV during the growing period in primary and secondary schools are also important factors leading to myopia.
Personal factors: when reading and writing, the posture is not correct, the distance between eyes and writing is not kept above 3-4 cm, every 3-4 minutes of reading and writing, no outdoor activities or overlooking for 1 minutes, using eyes at close range for a long time; Reading while walking or riding; Read and write in places where the light is too weak or too strong.
In view of these factors, parents should monitor their children's time of surfing the Internet and watching TV, and also let their children develop a good study habit.

Four elements of preventing myopia
25-9-6
There are two causes of myopia: congenital factors are related to heredity, and acquired factors are related to society, environment and eye habits. In terms of acquired factors, we should master the following four elements to prevent myopia:
Social prevention
According to the survey data, mild myopia mostly occurs in school-age children, and with the increase of educational level, the incidence of myopia is getting higher and higher. In today's society, schools and parents expect too much from their children, and their knowledge is updated quickly, so they add a lot of unreasonable extra burdens to students, which leads to an increase in the probability of myopia. Let the child be relatively relieved and relaxed in the process of eyeball development.
School prevention
First of all, the school's environmental facilities, the classroom should be spacious and bright, the lighting distribution should be scientific and reasonable, the height of tables and chairs should be appropriate, and the blackboard should have large fonts and clear handwriting. Secondly, the school's eye education, regular eye examination, combined with the students' respective vision, regular seat change, left, middle and right rotation; Finally, reduce the amount of homework and reduce the burden of students' eyes.
family prevention
(1) To create a good learning environment, especially lighting, it is advisable to use 8-15 watt fluorescent lamp or 25-4 watt light bulb, and the light should come from the left front, and the distance between the lamp and the desk is 5-67 cm. (2) Cultivate the correct habit of using eyes, sit upright, keep your eyes about 1 foot away from the book, and your writing hand about 1 inch away from the pen tip. It is advisable to rest for 15 minutes after reading for about 1 hour. Watching TV should not be too long, and you should rest for a few minutes for 1 hour. The distance between your eyes and the screen is 5 times the diagonal of the TV screen. (3) Children's food should not only contain fruits and vegetables rich in vitamins and trace elements, but also contain a certain amount of sugar, protein and fat, such as meat, eggs and milk, because the health of eyes comes from the health of the whole body.
Self-prevention
Take an active part in physical exercise, enhance physical fitness, improve the adjustment of eye muscles, and achieve a combination of work and rest, giving consideration to both distance and distance; Consciously do eye exercises to eliminate part of eye muscle fatigue; Develop good eating habits, not partial eclipse, not picky eaters; Develop good living habits, go to bed early and get up early, and arrange your study time reasonably; In addition, you can also take time to put your index finger in front of your eyes and keep your eyes on the fingers of your index finger from far to near, so as to train the adjustment ability of your eye muscles. However, this method should be carried out under the advice of a doctor. Jin wanqing
6. study notes on "common sense of protecting eyesight"
1.
no. The main purpose of squinting at things is to make the pupils smaller, so that less light enters the eyes, enhancing the light concentration, and thus seeing things more clearly. This action does not damage the eyesight.
2. reading in dim light or writing too small will hurt your eyesight?
no. This statement is like "taking pictures in poor light will damage the camera". When the light is dim, people's pupils will be enlarged and the retina will not be damaged by the intensity of external light.
3. Being too close to the TV or staring at the computer screen for a long time will damage your eyes?
no. This situation will hurt the eyes, but it is only temporary. Most of the problems come from the screen. Once the blink of an eye is reduced, the tear film will dry, which will affect the visual effect, but this is only a temporary phenomenon.
4. Are eye problems hereditary?
not necessarily. Many eye problems are related to genes, but sometimes the related genes may not be passed on to the next generation. For example, cataracts are related to age, not genes. It is worth noting that some eye diseases are hereditary, such as glaucoma, and it is best for people with this family history to have regular checkups.
5. When people get old, their eyesight will definitely deteriorate?
no. Some problems caused by aging are inevitable. Cataract is not a disease, but an aging phenomenon, which is the same as hair turning white. Of course, cataracts, like many other eye problems, can be corrected.
6. Will eating carrots improve your eyesight?
not in most cases. Diet is very important for eyesight, but it doesn't mean that eating carrots all day will give you eagle-like eyesight. Vitamin A deficiency can lead to decreased vision, but excessive intake can not enhance vision. However, some foods are really good for eyesight, such as spinach and broccoli containing lutein.
7. There are at least 5 tips for protecting your eyesight.
You can refer to the following methods to protect your eyes and control the growth of myopia:
First, it is not advisable to use your eyes at close range for too long. You should take a short rest for 3-15 minutes every 4-5 minutes and look far away for a while to alleviate your vision fatigue.
second, read and write, play computer, keep correct posture, the height of tables and chairs should be appropriate, and the distance between eyes and reading materials should be about 33 cm.
Third, mix whole grains with meat and vegetables, eat more vegetables and fruits, and don't be partial to food. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food is prone to myopia.
fourth, when reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front to avoid the shadow of the hand obstructing the line of sight. The light should be soft, such as incandescent lamps, which should be between 25 and 4W. Reading in the sun is not recommended. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation and increase the intensity of eye labor, which will easily lead to myopia after a long time. Generally, the desk lamp should be below 4 watts.
5. avoid reading while walking or reading in a walking carriage. Because the carriage is shaking, the body is shaking, and the distance between eyes and books cannot be fixed, the burden of glasses will increase. If you do this often, you are likely to get myopia.
6. Take an active part in physical exercise to enhance physical fitness. When the eyeball follows the target, the continuous relaxation and contraction of ciliary muscles and the synergistic effect of extraocular muscles can improve the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the physical quality is closely related to the occurrence of myopia in children. Children with malnutrition and weak constitution are prone to myopia.
7. Insist on doing correct eye exercises. Through acupoints around the eyes, the blood circulation in the orbit can be enhanced, the neuronutrition can be improved, the excessive congestion in the eyes can be eliminated, and the purpose of relieving eye fatigue can be achieved, which is beneficial to the prevention and treatment of pseudomyopia of teenagers, and it is a good method for self-care of teenagers' eyes.
eight, eat less candy and high-sugar food. Too much sugar will produce a large number of acidic substances in the blood, and the combination of acid and salt in the body, especially calcium, will reduce blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.
9. Go to the eye hospital to check your eyesight regularly, and correct it in time if you find that it is declining, so as to prevent myopia from deepening.
ten, eat less sweets. Because sugar needs a lot of vitamin B1 when it is metabolized in the body, if sugar is ingested too much, vitamin B1 will be insufficient. Vitamin B1 deficiency will affect the growth and development of optic nerve, which will lead to the decline of vision. Excessive intake of sugar will also reduce calcium in the body, weaken the elasticity of the eye and promote the occurrence and development of myopia.
8. Tips on eye protection
Tips on eye protection:
First, develop good eye habits, and be sure to watch less TV, mobile phones, computers and other electronic products.
Second, watch more green things and do eye exercises.
Third, keep your distance from reading, don't use your eyes for a long time, pay more attention to rest and avoid staying up late.
fourth, the indoor lighting brightness should not be too high.
5. Eat more foods to protect your eyes:
To protect your eyes, you can eat foods rich in vitamin A, such as fish, animal liver, seafood, cream, eggs and carrots to prevent night blindness, xerophthalmia and keratomalacia in children.
Eat more fruits that are good for your eyes: blueberries (rich in vitamins, amino acids, minerals and anthocyanins, which can improve your night vision).
cherry tomatoes (containing va, VC and VP, with strong antioxidant capacity), kiwifruit (king of VC, preventing cataracts) and apples (eyesight improving fruit, containing va and trace element selenium).
Eat more fruits containing vitamin A: loquat, cherry, banana, longan, apricot, litchi and so on.
