2. Common sense of protecting eyes
When watching TV, surfing the Internet or studying every day, it's best to rest with your eyes for about 40 minutes, so that your eyes can see the distance, or close your eyes for a while, and then do eye exercises in the second quarter ~ I don't think it's necessary to say more about how to do it in the second quarter ~ Everyone should try not to read in too strong or too weak light at ordinary times ~ It's easier to hurt their eyes! Don't read books and newspapers on the bus, it's bad for your eyes to wander around like that ~
Many people like to turn off all the lights in the room when watching TV at night. They think the TV screen looks bright and clear. Actually, it's not good for your eyes. There is a big difference between the brightness of the TV screen and the surrounding scenery, which will aggravate the fatigue of the eyes. Therefore, when watching TV at night, don't turn off all the lights, but keep the room bright, such as turning on a 3-8 watt light, but don't let the light shine directly on the screen.
Green is good for eyes, not green itself, but overlooking the natural scenery can relieve eye fatigue. If you look at something smaller than 33 cm, even if it is green, it is not good for your eyes.
Because there are many people surfing the Internet now, I want to tell you something to pay attention to when surfing the Internet:
● Rest your eyes every 1 hour, and don't continue the operation.
● When using the computer continuously, blink frequently to prevent dry eyes.
● The screen 35cm away from the eyes should not be less than 60cm, and the screen 38cm away should not be less than 70cm. The screen should be placed slightly below the horizon.
● Adjust the brightness and clarity of the screen to an appropriate level according to the comfort of eyes.
● Wipe the screen frequently. A dirty screen will blur the image and cause eye fatigue.
Finally, I tell you that you can eat more foods containing vitamin A, such as eggs, milk, pork liver, cakes and so on. Or eat more fruits and vegetables, such as carrots, bean sprouts, oranges, oranges and red dates. It has a certain effect on protecting eyesight.
3. No less than 50 tips to protect your eyesight.
You can refer to the following methods to protect your eyes and control the growth of myopia: First, the time for using your eyes at close range should not be too long. You should take a short rest for 3-5 minutes every 40-50 minutes and look at the distance 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.

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.
