To sum up (this is for me personally):
First of all, because glasses are placed directly on the eyeball, although there is medicine to wash them, there are always some things that can't be washed clean. I once bought a pair for hundreds of dollars and lost it soon. It is strongly recommended not to wear contact lenses. As for the hand, I don't know how to say it. Anyway, many people around me and I are afraid to go, but some people succeeded (that's my classmate), just don't know how to develop in the future. It's hard to tell. It is said that surgery is forbidden now, and so on. I dare not go anyway.
Secondly:
First, massage exercises (eye exercises)
Lie on your back or supine, close your eyes naturally, and then massage the acupoints around your eyes in turn. Need to choose accurate points, gentle techniques, there is a feeling of local pain.
1. Kneading Tianying Point: Gently press Tianying Point (lower brow and upper angle outside orbit) with both thumbs.
2. Squeeze Jingming point: Gently press Jingming point with the thumb of one hand (the root of the nose is close to the inner canthus of both eyes), first press down and then squeeze up.
3. Knead Sibai Point: Knead Sibai Point with your index finger in the center of your cheek (straight down to the middle of the lower edge of your orbit).
4. Press the temple wheel to scrape the eye socket: press the temple with the thumb (a horizontal finger backward between the brow tip and the outer corner of the eye), and then gently scrape the eye socket with the inner side of the second section of the curved index finger, from the inside up-> External top->; Outside-> Under the inside, massage the acupoints around the eye socket, such as bamboo waist, hollow bamboo pole, pupil dredging, ball back, weeping and so on. Conducive to pseudomyopia or prevent myopia from deepening.
Second, the eye ironing method
This method is best to sit, relax, close your eyes, and then quickly rub your palm to make it warm. Cover your eyes with your hands when it is hot. After the heat dissipates, suddenly take your hand away and open your eyes hard at the same time. This can promote the blood circulation and metabolism of your eyes 3 ~ 5 times.
Third, the eye breathing concentration method
Choose a place with fresh air, or sit or stand, relax, look straight ahead, slowly inhale the air, then open your eyes wide, pause for a moment, then exhale the air slowly, then close your eyes slowly, and do it for 9 times in a row.
Fourth, blink.
Choose a quiet place, or sit or stand, relax, clear your mind, open your eyes, keep your head and neck still, and turn your eyes alone. First, stare directly below, slowly turn left, then turn directly above, turn right, and finally return to directly below. Turn clockwise nine times like this. Then turn your eyes from staring down to the right, top, left, and then back to the bottom. Turn counterclockwise 9 times like this. Do it four times in all. Every turn, the eyeball should reach the limit as much as possible. This blinking method can exercise eye muscles, improve nutrition and make eyes flexible and bright.
Five, staring at the distance:
/kloc-find a meadow or green tree 0/0 meters away: green is imaged in front of the retina due to the short wave length, which can promote eye adjustment and relaxation, relax the ciliary muscles of the eyes and reduce eye fatigue. Don't squint, don't blink all the time, eliminate distractions, concentrate on staring for 25 seconds, and recognize the outline of grass leaves or leaves. Then put the left palm slightly higher than 30 cm in front of your eyes and read the palm prints one by one from beginning to end for about 5 seconds. Look at the palm print, then stare at the grass or leaves in the distance for 25 seconds, and then look at the palm print. /kloc-repeat 20 times in 0/0 minute, three times a day, and increase the number of trainings if the vision drops badly.
There are also hot water to wash your eyes or apply hot handkerchiefs to your eyes and temples.
Scattered are:
Auxiliary training method for restoring vision

2, crystal operation
● Blinking: Hold your chin with both hands, let your eyes rotate 10 times in the order of up, down, left and right, and then rotate 10 times counterclockwise and clockwise respectively.
● Find a scene 3 meters away (such as calligraphy and painting on the wall). ), at the same time, raise your left hand slightly higher than your eyes and straighten it (about 30 cm). After seeing the handprint clearly, look at Qingyuan again, and move your eyes between them as quickly as possible, going back and forth for 20 times.
3. Massage practice
Lie on your back or supine, close your eyes naturally, and then massage the acupoints around your eyes in turn. Need to choose accurate points, gentle techniques, there is a feeling of local pain.

Netizen Persian sugar: TV can be managed, and computers can also be managed, as long as they are controlled within a reasonable time. I think reading is more eye-consuming than watching TV and computer, so the most important thing is to use eye hygiene, pay attention to posture, pay attention to light and so on. If you feel nearsighted, let your child play table tennis for a month. Recently, it has been seen that it has a preventive effect on myopia.
Netizen Peter's mother: insisting that children practice rolling their eyes 20 times a day can improve myopia. His child's vision used to be 0.8, but now it has returned to 1.2 after several months. It is also said that this kind of exercise can prevent myopia and is more effective than eye exercises. You might as well let the children try. Yesterday, I went to the specialist clinic of Capital Institute of Pediatrics to see an ophthalmologist (Peter has chalazion in his eyes). Many children go to check their eyesight and prepare glasses. Alas, seeing my parents' anxious eyes, I am really worried that this is my son's future. Therefore, under the current pressure of study, firstly, children should participate in sports and outdoor activities, increase the chances of overlooking and rolling their eyes, and reduce the use of screens and eyes at close range. Obviously, there are more children wearing glasses nowadays than in our time. Is this also the progress of the times?
Netizen Dan Qing 0604: I recently bought a preventive alarm for my son and hung it on my ear. When the head is close to the desk, it will make a sound. I think it's quite scientific. I bought a shelf for correcting sitting posture before, but it affected the effect of writing, and my son was uncomfortable with it.
For people who often watch computers-prevention and treatment of dry eye.
Our eyes, especially the cornea, often rely on lacrimal glands for water supply. By blinking, tears become a layer of "tears" and spread to the cornea to keep the eyes comfortable. The so-called "dry eye" refers to a symptom of leaving tiny scars on the eyes due to the decrease of tears or the decline of lacrimal gland function. In the past, dry eye, cataract, glaucoma and other diseases were mainly common eye diseases of the elderly, but now it is found that more and more young people and white-collar workers often contact computers, televisions and game machines in some cities. According to the investigation of relevant departments, 90% of people who work in front of the computer for more than 3 hours every day have eye problems. This so-called "computer vision syndrome" is a manifestation of dry eye.
1. Clinical symptoms of dry eye
The common symptoms of dry eye are dry eyes, burning pain and more gums; Acid eyes, itchy eyes, fear of light, decreased vision. Other symptoms include headache, irritability, fatigue and difficulty in concentration. In severe cases, corneal softening and perforation will occur, and conjunctival congestion can be seen during examination.
2. Causes of dry eye syndrome
There is a layer of tears between the upper and lower eyelids, which contains substances to protect the eyes from infection. When people blink, tears are evenly distributed on the eyeball, cleaning the dust on the conjunctiva and keeping the eyes bright. The average person's tear secretion will decrease with age, so the incidence of dry eye in the elderly is higher. There are many factors that cause dry eye, including: the decrease of tear secretion after middle-aged and elderly people, and the symptoms of the eyes themselves, such as corneal degeneration, blepharitis and trachoma. Various immune diseases and connective tissue diseases, such as rheumatoid arthritis, lupus erythematosus, xerostomia, arthritis syndrome (more common in middle-aged and elderly women); It is caused by certain drugs, such as birth control pills, sleeping pills, sedatives, cough medicines, stomach medicines, etc. ; It may also be caused by vitamin A deficiency.
In recent years, the trend of dry eye is obvious, mainly because in modern life, young people have more and more contact with TV and computers for work and entertainment, and they face the fluorescent screen for a long time, lacking in blinking or letting their eyes rest in time, which affects the secretion of tears in their eyes; Or long-term use of some eye drops, such as vasoconstrictor eye drops, is also easy to form dry eye.
3. How to prevent dry eye?
(1) The best way to effectively prevent dry eye is to develop the habit of blinking more. Professionals believe that dry eye is a stress-type disease, and the problem lies in the eyes staring at one direction for a long time. Therefore, the best way to avoid eye fatigue is to rest properly and avoid continuous work. If you are an optician, it is very important to match a pair of suitable glasses. People over 40, it is best to use bifocal lenses, or wear glasses with low degree when typing. Working posture and distance are also important. Try to keep a distance of 60cm, adjust the most suitable posture, and keep the line of sight down about 30o. Such an angle can relax muscles and minimize the area of the eyeball surface exposed to the air.
(2) Long-term computer operators should eat more fresh vegetables and fruits, and increase the intake of vitamins A, B 1, C and E. In order to prevent dry cornea, dry eyes, decreased vision and even night blindness, computer operators should eat more foods rich in vitamin A, such as bean products, fish, milk, walnuts, vegetables, Chinese cabbage, water spinach, etc. Vitamin c can effectively inhibit cell oxidation. The main functions of vitamin E are: lowering cholesterol, removing garbage in the body and preventing cataracts. Walnuts and peanuts are rich in vitamin E, and vitamin B 1 can nourish nerves. Green leafy vegetables contain a lot of vitamin B 1. Drink green tea properly every day, because lipopolysaccharide in tea can improve the hematopoietic function of the body, and tea also has the function of preventing radiation damage.
(3) In order to avoid the fluorescent screen from reflecting or being unclear, the computer should not be placed on the opposite or back of the window, and the ambient lighting should be soft. If there are windows behind the operator, curtains should be drawn to avoid eye fatigue caused by bright images reflected by direct light on the screen. Usually, the average person blinks less than 5 times per minute, which will make his eyes dry. When a person works in front of a computer, he blinks only one-third of the usual frequency, thus reducing the secretion of lubricants and enzymes in his eyes. You should blink more and rest at least once an hour.
(4) In order to reduce the dryness of eyes, corneal nutrient solution can be properly used at eye points. Such as: Befu Shu eye drops, Xiao Laiwei eye drops and some artificial tears. In addition, eye exercises can also relax eye adjustment and reduce visual fatigue. The essence of eye exercises is self-massage, that is, by self-massaging the acupoints and skin muscles around the eyes, the blood circulation in the eye socket is increased, the nerve nutrition is improved, and the hyperemia of the brain and eyeball is eliminated. Because of the smooth circulation, the intraocular accommodation muscle can eliminate the accumulated metabolites, thus achieving the purpose of eliminating eye fatigue.
So it needs to be reminded that when you concentrate on the computer screen, the number of blinks will decrease. I suggest you blink more to ensure that the "tear film" can disperse water to the cornea to prevent dry eyes. If you suspect that you have dry eye, you should see a doctor as soon as possible.

How do people who need to improve their eyesight and overuse their eyes choose health food?
Eyes are visual organs, stimulated by light, which make the body perceive the images, colors and movements of objective objects. The main part of the eye is the eyeball. The reason why the eyes can see objects is that the transparent matrix of cornea, aqueous humor, lens and vitreous body of the eyeball distorts and turns the external light to the retina. The retina can feel the stimulation of light because it contains two kinds of photosensitive cells, namely cone cells and rod cells. Under the action of light, a series of chemical changes have taken place in photoreceptor cells. Through these chemical changes, light energy can be converted into electrical energy, causing nerve impulses and transmitting them to the visual center to produce vision.
In medicine, the ability of the eye to finely distinguish the shape of an object, that is, the ability to distinguish the minimum distance between two points, is called vision. There are many reasons for poor eyesight. They are: ① various types of ametropia, including hyperopia, myopia and astigmatism; ② lens opacity, that is, cataract; ③ corneal opacity; ④ vitreous opacity and hemorrhage; ⑤ optic nerve diseases, such as optic nerve atrophy. Optic neuritis, retrobulbar optic neuritis, chronic glaucoma and toxic amblyopia; ⑥ Circulatory blindness, occasionally seen in severe uremia and retinal arteriosclerosis, is mostly temporary; ⑦ Vein or retinal tumor and retinal detachment; 8 acute glaucoma; Pet-name ruby acute iriditis; Attending intraocular bleeding, etc. Among them, myopia is the most common, which is caused by many reasons, such as poor learning environment, incorrect reading and writing posture, too long reading time, weakness, anemia, endocrine disorders, excessive fatigue and so on. Health food for improving visual function can adjust and improve the physiological mechanism of myopia through the above links.
1. A food with eyesight improving effect
To protect eyesight and prevent eye diseases, we need to start from many aspects, among which paying attention to nutrition is also helpful to improve eyesight. In the daily diet, foods that can improve eyesight are:
(1) Foods rich in vitamin A are closely related to normal vision. If vitamin A is insufficient, the regeneration of rhodopsin is slow and incomplete, and the dark adaptation time is prolonged, which can cause night blindness in severe cases. If vitamin A in the diet continues to be deficient or insufficient, dry eye will appear, and the condition will further develop into corneal softening and corneal ulcer, as well as corneal folds and Pitt spots. The best food sources of vitamin A are various animal livers, cod liver oil, fish eggs and poultry eggs. Vitamin A contained in carrots, spinach, amaranth, alfalfa, red sweet potatoes, pumpkins, green peppers and other vegetables can be converted into vitamin A in the body.
(2) Foods rich in vitamin C can reduce the damage of light and oxygen to the lens of eyes, thus delaying the occurrence of cataracts. Foods containing vitamin C include persimmon pepper, tomato, lemon, kiwi fruit, hawthorn and other fresh vegetables and fruits. (3) Calcium, calcium is related to eyeball composition, and calcium deficiency can lead to myopia. Teenagers are at the peak of their growth, and the demand for calcium in their bodies is relatively increasing. If you don't pay attention to calcium supplementation, it will not only affect bone development, but also reduce the elasticity of the developing eyeball wall-sclera, increase the internal pressure of the lens, lead to the elongation of the anterior and posterior diameter of the eyeball, and lead to myopia. Foods containing more calcium mainly include milk and its products, shellfish (shrimp), bone meal, beans and bean products, egg yolk, dark green vegetables and so on.
(4) chromium, chromium deficiency is easy to cause myopia, chromium can activate insulin, so that islets can play the greatest biological effect. For example, the lack of chromium in human body will hinder the function of insulin in regulating blood sugar, increase the osmotic pressure of plasma, lead to the increase of osmotic pressure and diopter of eyeball lens and aqueous humor, and thus induce myopia. Chromium is mostly found in brown rice and wheat bran, and it is also abundant in animal liver, grape juice and nuts.
(5) Zinc, zinc deficiency will lead to visual impairment, and zinc is mainly distributed in bones and blood in the body. Corneal epidermis, iris, retina and lens also contain zinc. Zinc participates in the replacement and transportation of vitamin A in the eyes, maintains the normal tissue state of retinal pigment epithelium and maintains normal visual function. Foods containing more zinc include oysters, meat, liver, eggs, peanuts, wheat, beans and miscellaneous grains.
(6) Pearl, which contains more than 95% calcium carbonate and a small amount of minerals such as magnesium oxide and aluminum oxide, and contains a variety of amino acids, such as leucine, methionine, alanine, glycine, glutamic acid and aspartic acid. Pearl is sweet, salty and cold. The "Zhu Zhen Powder" made of pearl powder, borneol and amber can inhibit the formation of cataract.
(7) kelp. Kelp contains 1/3 mannitol in addition to iodine. There is a thick layer of "frost" on the surface of dried kelp, which is mannitol in kelp. Mannitol has diuretic effect, which can reduce intraocular pressure and has a good effect on the treatment of acute glaucoma. Other seaweeds such as Undaria pinnatifida also contain mannitol, which can also be used as an auxiliary food to treat acute glaucoma.
2. Health foods that help improve eyesight can increase nutrition and improve eyesight through diet, so eat more of the above foods. If we can choose appropriate health food that can improve our eyesight on the basis of daily diet, it can play a very good role in adjuvant therapy. Optional healthy foods are:
(1) Foods rich in vitamin A, such as medlar products.
(2) It is rich in protein, polypeptide and some amino acids, such as taurine and nucleic acid.
(3) Health tea, granule or capsule containing cassia seed, chrysanthemum, hawthorn and pearl powder.

Massage more to improve eyesight, massage more: Jingming point, Sizhu point, temple, Yuyao point, Sibai point, Chengqi pocket and other points around the eyes.
Respondent: Tang Ziwei University1Grade 7 8- 1 15:4 1.
The eyes are the most important organs among the five senses, and people say that the eyes are the windows and mirrors of the soul. Bright, clear and divine eyes give people vitality and beauty. The structure of the eyes is so complicated that it needs good nutrition to maintain it, and all kinds of nutrition should be comprehensive. If the diet is not well nursed, the skin around the eyes is particularly fragile. If you don't pay attention to protection at ordinary times, it will lead to dull eyes, myopia, puffiness of eyelids, drooping bags under the eyes, dark circles and wrinkles around the eyes, giving people a feeling of depression, aging and morbidity, which will affect the beauty of the face and the whole.
In order to protect the beauty of eyes, we should pay attention to choosing healthy food for eyes in our daily diet and ensure the nutritional supply of eyes. Choose foods rich in vitamin A. Vitamin A can protect the tissue and structure of eyes, maintain the normal efficacy of rhodopsin, and prevent night blindness and dry eye. You can choose to eat animal liver, kidney, milk, cream and egg yolk, eat green leafy vegetables, carrots and all kinds of fresh fruits that can be converted into vitamin A, and choose foods containing vitamin B 1. Vitamin B 1 can protect optic nerve, maintain normal vision, prevent optic nerve degeneration and prevent eye diseases such as cataract. Foods rich in vitamin B 1 mainly include animal liver, kidney, lean pork, egg yolk, coarse rice, coarse flour, soybean, sesame, barley, wheat, milk, eel, buckwheat, germ, malt, chestnuts, peas and green leafy vegetables. You should also choose more cold foods that clear the liver and improve eyesight, such as duck meat, duck eggs, snail, snakehead, mussel meat, mung bean, lotus root, water chestnut, wax gourd, Zizania latifolia, cucumber, loofah, wolfberry leaf, mint, lettuce, bitter gourd, laver, bamboo leaves and water shield. In order to protect your eyes, you should also pay attention not to eat or try to eat less irritating and spicy foods such as pepper, garlic, pepper, curry, strong tea, liquor, cigarettes and fried foods. Because these foods are irritating and hot, it is easy to damage the optic nerve and blur the vision.
In addition to diet and health care, eyes should also be protected to keep healthy and bright. For example, the posture of reading and writing should be correct, and the distance between the eyes and the book should be 1 foot when reading. Lie down without reading, walk without reading, and ride without reading. When reading, you should generally get up and move every hour, cover your eyes with your palm and massage gently, then look into the distance. It is best to look at green plants, because green plants can absorb ultraviolet rays under strong light, reduce or eliminate the harmful effects of ultraviolet rays on people's eyes, and give people a comfortable feeling. And often do eye exercises, press the temples, or close your eyes. Closing your eyes can not only give your eyes a full rest, but also give your brain a rest. ?
Don't smoke, because smoking will destroy a lot of vitamin A and vitamin B 12 in the body, damage the optic nerve and affect vision. People with eye diseases quit smoking, and their eye diseases will obviously improve. Don't look at the bright light. The sun is fierce in summer. Wear a sun hat or sunglasses when you go out to prevent ultraviolet rays from hurting your eyes and keep them healthy.
