Four elements of preventing myopia

2005-09-06

The causes of myopia are congenital and acquired. Congenital factors are related to heredity, and acquired factors are related to society, environment and eye habits. To prevent myopia from acquired factors, we should master the following four elements:

Social prevention

According to the survey data, mild myopia mostly occurs in school-age children, and with the improvement of education, the incidence of myopia is getting higher and higher. In today's society, schools and parents expect too much from their children and update their knowledge quickly, which adds a lot of unreasonable extra burdens to students and leads to an increase in the probability of myopia. Let children get relative relief and relaxation 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, the font on the blackboard should be large and the handwriting should be clear. Secondly, the school's eye education, regular eye examination, combined with students' respective eyesight, change seats regularly, and rotate left, middle and right; Finally, reduce the amount of homework and reduce the burden on students' eyes.

Family prevention

(1) To create a good learning environment, especially lighting, it is advisable to use 8- 15 watt fluorescent lamps or 25-40 watt bulbs. The light should come from the left front, and the distance between the lamp and the table is 50-67 cm. (2) Cultivate the correct habit of using eyes, sit upright, the distance between eyes and books is about 1 ft, and the distance between the writer and the pen tip is about 1 in. It is appropriate to rest after reading for about 1 hour 15 minutes. Don't watch TV for too long. 1 hour, take a break for a few minutes. The distance between your eyes and the screen is five 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

Actively participate in physical exercise, enhance physical fitness, improve the adjustment ability of eye muscles, and achieve a combination of work and rest, giving consideration to both distance and distance; Consciously do eye exercises to eliminate some 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 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 and near to train the adjustment ability of eye muscles. However, this method should be carried out at the doctor's suggestion. Jin Wanqing

6. "Common sense of protecting eyesight" study notes

1, squinting at things is easy to hurt your eyesight?

No, the main purpose of squinting at things is to make the pupils smaller, so that less light enters the eyes, enhancing the concentration of light, and thus seeing things more clearly. This action does not damage the eyesight.

2. reading or writing too small in dim light 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 dilated 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 number of blinks decreases, the tear film will dry and affect the visual effect, but this is only a temporary phenomenon.

4. Can eye problems be inherited?

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 and have nothing to do with genes. It is worth noting that some eye diseases are hereditary, such as glaucoma. People with this family history should have regular checkups.

When people get old, their eyesight will definitely get worse?

No, some problems brought by aging are inevitable. Cataract is not a disease, but a phenomenon of aging, just like hair turning white. Of course, cataracts, like many other eye diseases, can be corrected.

6. Eating carrots can improve your eyesight?

Not in most cases. Diet is very important for eyesight, but it doesn't mean that you can have eagle-like eyesight by eating carrots all day. 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, which contain lutein.

7. At least 50 tips to protect 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 rest for 3-5 minutes every 40-50 minutes and look far away for a while to relieve visual fatigue.

Second, read and write, play computer, keep the correct posture, the height of tables and chairs should be appropriate, and the distance between eyes and reading materials should be kept at about 33 cm.

Third, mix whole grains with vegetarian food, eat more fruits and vegetables, and don't be partial to food. Lack of vitamins in food is prone to night blindness and dry eye, 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 blocking the line of sight. The light should be soft, such as incandescent lamp, which should be between 25-40W. 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 adjustment and eye labor, which will easily lead to myopia after a long time. Generally, the desk lamp should be below 40 watts.

5. avoid reading while walking, or reading in the walking carriage. Because the carriage is shaking, the body is shaking, the distance between the eyes and the book can not be fixed, and the burden of glasses will increase. If you do this often, you are likely to be nearsighted.

Six, actively participate in physical exercise, enhance physical fitness. When the eyeball follows the target movement, the continuous relaxation and contraction of ciliary muscles and the synergistic effect of extraocular muscles can improve the blood perfusion of the eyes, promote the metabolism of the eyes, and thus reduce eye fatigue. Moreover, physical fitness is closely related to the occurrence of myopia in children. Children with malnutrition and weak constitution are prone to myopia.

Seven, insist on doing correct eye exercises. Through the acupuncture points around the eyes, the orbital blood circulation can be enhanced, nerve nutrition can be improved, eye hyperemia can be eliminated, and the purpose of relieving eye fatigue can be achieved, which is beneficial to the prevention and treatment of juvenile pseudomyopia, and it is a good method for adolescent eye self-care.

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 the blood calcium, affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

Nine, regularly to the eye hospital to check vision, found that the decline should be corrected in time to prevent myopia from deepening.

Ten, eat less sweets. Because sugar needs a lot of vitamin B 1 when it is metabolized in the body, if you consume too much sugar, vitamin B 1 will be insufficient. Vitamin B 1 deficiency will affect the growth and development of optic nerve, leading to decreased vision. Excessive intake of sugar will also reduce calcium in the body, weaken the elasticity of the eyes and promote the occurrence and development of myopia.

8. Protect your eyes.

Protect your eyes. Popular science:

First, develop good eye habits, and be sure to watch less TV, mobile phones, computers and other electronic products.

Second, look at something green or do eye exercises.

Third, keep the distance between books, 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.

Five, eat more food to protect your eyes:
