1, distant gaze:
Find a 10 meters away from the grass or green trees: green due to shorter wavelengths, imaging in the retina before, prompting the eye regulation relaxation, eye ciliary muscle relaxation, reduce eye fatigue. Don't squint or blink, remove distractions, concentrate and stare intently for 25 seconds to recognize the outline of grass or leaves. Next, hold the palm of your left hand slightly higher than 30 centimeters in front of your eyes, and look at the palm prints one by one, from head to tail, for about 5 seconds. After looking at the palm prints and then gaze at the distant grass or leaves for 25 seconds, and then look at the palm prints. 10 minutes time to repeat 20 times a day to do three times, the vision loss is very strong to increase the number of training.
2, crystal drill
● Turning eyes: hands on the cheeks, let the eyeballs according to the order of up, down, left, right turn 10 times, and then counterclockwise, clockwise each turn 10 times.
● Find a scene 3 meters away (e.g., paintings on the wall, etc.), and raise your left hand slightly above your eyes and straighten it out (about 30 centimeters), see the palm prints, and then look at the distant objects, and try to move your eyes between the two as quickly as possible, and back and forth 20 times.
3, massage exercise
Take a sitting or supine can be, will be naturally closed eyes, and then in turn massage points around the eyes. Requirements for accurate acupuncture points, gentle techniques, in order to localize the feeling of soreness and swelling to the degree.
1. Knead Tian Ying point: use both thumbs to gently knead and press the Tian Ying point (below the eyebrow, outside the upper corner of the eye socket).
2. Squeeze and press the eye point: use the thumb of one hand to gently rub and press the eye point (the root of the nose next to the inner canthus of the eyes) first downward, and then upward to squeeze
3. Rub the Sibai acupoints: use the forefinger to rub and press the Sibai acupoints in the central part of the cheeks (the lower margin of the eye sockets in the middle of the straight down a cross finger).
4. Press the solar plexus, round scraping the eye socket: press the solar plexus with the thumb (the middle of the tip of the eyebrow and the outer corner of the eye backward one cross finger), and then use the curved second section of the forefinger inner side of the light scrape the eye socket round, from the inner upper - & gt; outer upper - & gt; outer lower - & gt; lower inner, so that around the eye saves the bamboo fish waist, the Silk Bamboo empty, pupil liao, after the ball, Cheng Sue points such as massaged. For pseudomyopia, or to prevent the deepening of myopia is beneficial.

Netizen Persian sugar: TV can be watched as usual, the computer can be played as usual, as long as the control within a reasonable time. I feel that reading books than watching TV and watching the computer is more eye-catching, so well, the most important thing is eye hygiene, pay attention to posture, pay attention to the light, and so on the clichéd precautions. If you feel that there is a tendency of myopia, you may want to let your child play ping pong for a month, and recently I read that it has a preventive effect on myopia.
Peter's mom: I've been trying to get my kids to practice rolling their eyes 20 times a day to improve their myopia. His child's eyesight was 0.8, and now it's back to 1.2 after a few months of doing this. Also said that this exercise can defend against myopia, than eye exercises work. You may want to let your child try it. Yesterday, when I saw the ophthalmologist at the specialist clinic of the Capital Pediatrics Institute (Peter had a chalazion in his eye), a lot of children were there to have their eyesight checked and to get prescription glasses. Alas, seeing the anxious eyes of the parents, I am really worried that this is the future of my son. So, in this kind of learning pressure situation now, one is to let the child participate in more sports and outdoor activities . Increase the opportunity to look into the distance and eyeball rotation. Reduce screen and close-up eye use. Obviously feel that now children with glasses to be much more than our era, this is also the progress of the times?
Netizen Dan Qing 0604: I recently bought my son a preventive alarm, is hanging in his ears, when the head is close to the desk, it will make a sound, I think it's quite scientific, and I have previously bought a frame used to correct the sitting posture, but it affects the effect of the writing, and my son is uncomfortable with it.
For those who often look at the computer - the prevention and treatment of dry eye
Our eyes, especially the cornea part of the eye, often rely on the tear ducts to supply water, through the blinking of the eye, so that the tears into a layer of "tear film" dispersed to the cornea, to keep the eyes comfortable. This keeps our eyes comfortable. Dry eye syndrome is a condition in which the eyes show tiny scars due to a decrease in the number of tears or a decline in the function of the tear glands. In the past, dry eye disease, together with cataract, glaucoma and other diseases, was mainly a common eye disease of the elderly, but now it is found that some young people and white-collar workers in the city who often come into contact with computers, TVs and game consoles are also suffering from dry eye disease more and more. According to a survey of the relevant departments, every day in front of the computer more than 3 hours of work in the crowd, 90% of the people have problems with their eyes, this so-called "computer vision syndrome" is a manifestation of dry eye disease.
1. Clinical symptoms of dry eye
The general symptoms of dry eye disease are dry eyes, burning sensation, eye droppings more; eye acid, eye itching, fear of light and vision loss. Other symptoms include headache, irritability, fatigue, difficulty concentrating, and in severe cases, corneal softening and perforation can occur, and conjunctival congestion can be seen during examination.
2. Reasons for the formation of dry eye
Between the top and bottom of the human eyelids there is a layer of tears, which contains substances that protect the eyes from infection, people blinking with the performance of the tears evenly distributed in the eyeballs, cleaning the dust on the conjunctiva to keep the eyes bright. In general, people's tear secretion decreases with age, so the incidence of dry eye disease is higher among the elderly. There are many factors that can cause dry eye, including: decreased tear secretion after middle-age or old age, diseases of the eye itself, such as corneal degeneration, blepharitis, trachoma, etc.; a variety of immune diseases and connective tissue diseases, such as rheumatoid arthritis, lupus erythematosus, dryness of the mouth and eyes, arthritic syndromes (most often occurring in the middle-aged and old women), etc.; caused by certain medications, such as contraceptive pills, sleeping pills, tranquilizers, cough medicines, stomach medicines, etc.; can also be caused by vitamins and other medications, such as vitamins and other medications, Gastric medicines, etc.; can also be caused by vitamin A deficiency.
In recent years, the trend of dry eye disease is obvious, mainly due to modern life, young people's work and entertainment and television, computer contact more and more, long time to face the fluorescent screen, the lack of timely blinking or let the eyes rest, affecting the two eyes of the tear secretion; or long-term use of a certain kind of eye drops, such as vasoconstriction eye drops, but also very easy to form dry eye disease.
3. How to prevent dry eye disease
(1) The best way to effectively prevent dry eye disease is to develop the habit of blinking more. Professionals believe that dry eye disease is a stressful condition in which the problem lies in the eyes staring in one direction for a long time. The best way to avoid eye fatigue is to take breaks and avoid continuous operation. If you're a spectacle wearer, it's important to get the right pair of glasses, and for those over 40, it's best to use bifocal lenses or lower prescription glasses for typing. Working posture and distance is also very important, try to maintain a distance of 60cm, adjust the most appropriate posture, so that the line of sight can be kept down about 30o, such an angle can make the muscle relaxation, and make the surface of the eyeballs exposed to the air to minimize the area.
(2) Long-term computer operators should eat more fresh vegetables and fruits, and increase the intake of vitamins A, B1, C and E. To prevent corneal dryness and eye dryness, it is important to keep the eye in the right position, so that the line of sight can be kept downward for about 30o. In order to prevent corneal dryness, dry eyes, vision loss, and even night blindness, computer operators should eat more food rich in vitamin A, such as soy products, fish, milk, walnuts, bok choy, cabbage, cabbage, tomatoes and fresh fruit. Vitamin C can effectively inhibit cell oxidation. Vitamin E is mainly used to lower cholesterol, remove garbage from the body and prevent cataracts. Walnuts and peanuts are rich in vitamin E. Vitamin B1 can nourish the nerves, green leafy vegetables contain a large amount of vitamin B1. Daily green tea can be appropriate to drink, because of the lipopolysaccharide in the tea, can improve the hematopoietic function of the body, the tea also has the function of preventing radiation damage.
(3) In order to avoid reflections or unclear fluorescent screen, the computer should not be placed on the opposite side of the window or the back of the environmental lighting should be soft, if the operator behind the window should be closed curtains, to avoid the bright light directly irradiated to the screen reflecting a bright image caused by eye fatigue. Under normal circumstances, the average person blinks less than 5 times per minute will make the eyes dry. A person working in front of a computer blinks only one-third as often as usual, thus reducing the secretion of lubricants and enzymes in the eyes. You should blink more often and rest your eyes at least once an hour.
(4) In order to minimize the dryness of the eyes, you can use corneal nutrient solution in the eyes. Such as: BeiFu Shu eye liquid, XiaoLaiWei eye liquid and some artificial tears. In addition, eye exercises can also play a role in relaxing the eye regulation, reducing the role of visual fatigue. The essence of eye exercises is self-massage, that is, through self-massage of acupuncture points and skin muscles around the eyes, increase blood circulation in the eye sockets, improve nerve nutrition, can eliminate excessive congestion of the brain and the eyeballs, due to the circulation is smooth, the eye regulator muscle can eliminate the accumulation of metabolic products, to eliminate eye fatigue.
Therefore, it is important to remember that when you are fully focused on your computer screen, the number of times you blink will decrease. It is recommended that you blink more often to ensure that the "tear film" disperses water to the cornea of the eye to prevent dry eyes. If you suspect you have dry eyes, seek medical attention as soon as possible.

How to choose health food for those who need to improve their eyesight and use their eyes too much?
The eye is an organ of vision, which receives light stimulation, enabling the organism to perceive the image, color and movement of objective objects. The main part of the eye is the eyeball, the reason why the eye can see objects is due to the cornea of the eyeball, aqueous humor, lens and vitreous humor four parts of the transparent interstitial zigzagging external light imaging in the retina. The retina can feel the stimulation of light, because it contains two kinds of photoreceptor cells, namely, cone cells and rod cells, under the action of light, photoreceptor cells, a series of chemical changes occur inside, through these chemical changes can be transformed into electrical energy, causing nerve impulses, conduction to the visual center and produce vision.
Medically, the ability of the eye to make a fine discrimination of the form of an object, i.e., the ability to distinguish the minimum distance between two points, is called visual acuity. There are various causes of vision loss, they are: ① various types of refractive errors, including hyperopia, myopia, astigmatism; ② lens clouding, i.e., cataract; ③ corneal clouding; ④ vitreous clouding and hemorrhage; ⑤ optic nerve disorders, e.g., optic atrophy. Optic neuritis, retrobulbar neuritis, chronic glaucoma and toxic amblyopia; ⑥ circulatory blindness, occasionally seen in severe uremia, retinal atherosclerosis, mostly temporary; ⑦ choroidal or retinal tumors and retinal detachment; ⑧ acute glaucoma; ⑨ acute iritis; ⑩ intraocular hemorrhage and so on. Among them, myopia is the most common, the causes of myopia are manifold, the learning environment is not good, reading and writing posture is incorrect, reading time is too long, as well as physical weakness, anemia, endocrine disorders, excessive fatigue and so on are related to myopia. Health food to improve vision function is to play a certain role in regulating and improving the physiological mechanisms that cause myopia through the above links.
1. Foods that improve vision
Protecting vision and preventing eye diseases requires a multi-dimensional approach, which pays attention to nutrition, and is also helpful in improving vision. In the daily diet, with the role of improving vision food:
(1) rich in vitamin A food, vitamin A and normal vision has a close relationship. If vitamin A is insufficient, the regeneration of optic purplish red matter is slow and incomplete, and the dark adaptation time is prolonged, causing night blindness in severe cases. If dietary vitamin A continues to be deficient or insufficient, dry eye disease will occur, and the further development of this disease can become corneal softening and corneal ulcers, but also corneal folds and Bitou's spots. The best food source of vitamin A is a variety of animal liver, cod liver oil, fish eggs, poultry eggs, etc.; carrots, spinach, amaranth, alfalfa, sweet potatoes, pumpkin, green chili peppers and other vegetables containing vitamin A can be converted into vitamin A in the body.
(2) vitamin C-rich foods, vitamin C can weaken the light and oxygen damage to the eye lens, which slows down the occurrence of cataract. The food containing vitamin C is persimmon, which is a good source of vitamin C. Foods containing vitamin C include persimmon peppers, tomatoes, lemons, kiwi, hawthorn and other fresh vegetables and fruits. (3) Calcium, calcium is related to the composition of the eye, calcium deficiency will lead to myopia. Teenagers are in the peak growth period, the body's calcium needs relatively increased, if you do not pay attention to calcium supplementation, not only will affect bone development, but also will make the developing eye wall - sclera elasticity decreased, the lens pressure rises, resulting in the front and back of the eye diameter lengthened and lead to myopia. Foods containing much calcium, mainly milk and its products, shellfish (shrimp), bone meal, beans and soy products, egg yolk and dark green vegetables.
(4) chromium, chromium deficiency is prone to myopia, chromium can activate insulin, so that the pancreas to play the maximum biological effect, such as the human body chromium content is insufficient, will make insulin regulation of glucose dysfunction, plasma osmolarity increases, resulting in the lens of the eye, the aqueous humor of the osmolarity and refractive error increases, thus inducing myopia. Chromium is mostly found in brown rice, wheat bran, animal liver, grape juice, nuts are also rich.
(5) Zinc, zinc deficiency can lead to visual impairment, zinc in the body is mainly distributed in the bones and blood. Corneal epidermis, iris, retina and lens also contains zinc, zinc in the eye to participate in the vitamin A generation and transportation, to maintain the normal organization of the retinal pigment epithelium, maintenance of normal vision function. Foods containing more zinc are oysters, meat, liver, eggs, peanuts, wheat, beans, grains and so on.
(6) pearl, pearl contains more than 95% of calcium carbonate and a small amount of magnesium oxide, aluminum oxide and other minerals, and contains a variety of amino acids, such as leucine, methionine, alanine, glycine, glutamic acid, aspartic acid, etc., pearl taste sweet and salty cold, with pearl powder with lobster brain, amber and other formulations of the "real pearl scattered" points. The eyes can inhibit the formation of cataracts.
(7) kelp, kelp in addition to iodine also contains 1/3 of mannitol, sun-dried kelp surface has a thick layer of "white frost", which is the kelp in mannitol, mannitol has a diuretic effect, can reduce intraocular pressure, used in the treatment of acute glaucoma has a good effect. Other seaweeds such as wakame also contain mannitol, can also be used as a supplemental food for the treatment of acute glaucoma.
2. Health food to help improve eyesight Through diet can increase nutrition, improve eyesight, so we should consume more of the above food, if you can in the daily diet on the basis of the selection of appropriate with the function of improving eyesight health food, can play a good role in supporting the treatment. Health food can be used:
(1) Vitamin A-rich foods, such as wolfberry products.
(2) Rich in protein, peptides, certain amino acids, such as taurine, nucleic acids.
(3) Health tea, punch or capsule containing cassia seed, chrysanthemum, hawthorn and pearl powder.

Research has found that increasing protein and decreasing carbohydrate supply in the diet can reduce or abort the increase of myopia in adolescents who have a genetic background to develop myopia. Therefore, to avoid developing myopia, eat less candy and high-sugar foods. Eating too much sugar, will make the blood produce a lot of acid, acid and muscle salt, especially calcium, resulting in a reduction of blood calcium, which affects the toughness of the eyeball wall, so that the eye axis easy to elongate, contributing to the occurrence and development of myopia. Research surface, prevent myopia can be supplemented with protein, calcium, phosphorus, carrots, bean sprouts, oranges, mandarin oranges, jujubes, animal liver and other vegetables and fruits are also beneficial to the prevention of myopia.
Myopia diet
Research has proved that there is a considerable relationship between myopia and diet. To prevent myopia, you must pay attention to dietary regulation, otherwise the results will not be very effective.
Eating less sugar, and carbohydrate foods or overcooked protein foods will reduce the incidence of myopia. Eating too much sugar reduces the body's stock of the trace element chromium.
Ingesting too much overcooked protein foods can cause abnormalities in the body's calcium metabolism, resulting in calcium deficiency. Chromium and calcium, these two elements directly affect the body's regulation of intraocular hydraulics, if the body's chromium and calcium content is in a normal state of equilibrium, intraocular hydraulics can remain normal, so that we can prevent myopia.
So in daily meals, eat less sugar and overcooked protein foods. And pay attention to supplement the body of trace elements chromium, calcium. Chromium-rich foods include beans, wheat, eggs, chicken, pork and butter. You can add chromium- and calcium-rich foods to your daily diet to prevent the formation of myopia with dietary regulation.
Myopia is a type of refractive error. The formation of myopia has two main causes: internal and external. Internal causes refer to the hereditary nature of myopia. External causes mainly include the work environment and physical fitness. The incidence of myopia is more common in urban than rural areas, and more common in refined industries than in general industries, especially among students and intellectuals.
The physical factors in addition to heredity, mainly related to malnutrition. The lack of some or some important nutrients during the growth and development of the eye, so that the eye tissue becomes more fragile, in the role of environmental factors, the sclera of the eye wall is easy to dilate, so that the anterior and posterior axes of the eye to elongate and myopia occurs. Most myopic children have the habit of snacking, picking and favoring food. They eat mostly refined grains and fast foods, which lack nutrients or have more nutrient destruction. At the same time, their diet lacks high-quality protein foods such as milk, eggs, milk, fish, meat, chicken and coarse grain foods. The more types of food lacking, the greater the total amount, the higher the incidence of myopia and the higher the degree of myopia.
The formation of myopia is related to diet. Most myopic patients have low blood calcium and vitamin A deficiency; most adolescents with myopia have low serum proteins, as well as low blood calcium and blood pigment. After getting myopia, you should supplement vitamins A, B, family and trace elements such as calcium, chromium, zinc, etc., and eat less candies and high-sugar foods. Eating too much sugar and increased blood sugar levels can cause changes in the osmotic pressure of the atrial fluid and crystals. When the osmotic pressure of the atrial water is lower than that of the lens, the atrial water will enter the lens, prompting the lens to become convex, causing myopia to occur. When too much sugar and high carbohydrates are eaten, the elasticity of the tissues inside the eye decreases and the storage of the trace element chromium decreases, making the eye axis prone to lengthening. In addition, eating too much sugar produces large amounts of acid in the blood. Acid neutralizes with salts in the body, especially with calcium salts, and reduces them in the blood, causing a decrease in blood calcium, which affects the toughness of the eye wall, lengthens the eye axis, and also contributes to the occurrence and development of myopia.
In order to prevent the occurrence and development of myopia, the food selected for dietary therapy is mainly to supplement the nutrients necessary for the ciliary muscle and the sclera in the eye, to enhance the muscle strength of the ciliary muscle, to help it restore its intrinsic function; and to strengthen the sclera's toughness, to enhance its resistance to the outside world, and to prevent it from expanding.
Nearsighted people can supplement the following nutrients:
1. Protein:
As far as the sclera is concerned, it can become a tough shell of the eyeball, is due to the presence of a variety of essential amino acids, constituting a very strong fibrous tissue. Although the sclera has a certain toughness, but in the eye axis before and after the diameter of the site is still relatively weak. Meat, fish, eggs, milk and other animal foods are not only rich in protein, but also contains all the essential amino acids.
2. Calcium:
Calcium is the main component of bone, but also the main component of the sclera. Higher levels of calcium play a major role in enhancing the toughness of the sclera. Food in cattle bones, pig bones, sheep bones and other animal bones rich in calcium, and easy to be absorbed and utilized by the body. Others such as dairy, bean products, shrimp, shrimp, eggs, rape, cabbage, peanut rice, jujube and other calcium content is also more.
3. Zinc:
Myopia patients are generally deficient in chromium and zinc, myopia patients should eat more food containing more zinc. Foods such as soybeans, almonds, purslane, kelp, mutton, yellow fish, milk powder, tea, meat, beef, liver, etc. contain more zinc and chromium, which can be increased in moderation.
4. VitaminsVitamins are essential nutrients. Although the body's demand for them is very small, but they play an extremely important role in the body's material and energy metabolism. When treating myopia with dietary therapy, you should supplement more vitamins A, B1, B2, C, and E. Vitamin-rich foods include eggs, milk, meat, fish, liver, and fresh vegetables and fruits.5. Foods that replenish the liver and benefit the kidneys include wolfberries, walnuts, peanuts, jujubes, cinnamon balls, honey, shrimp, fish, meat, and eggs.
Introduction of some of the prevention and treatment of myopia food:
1. Breakfast: eggs 1 ~ 2 milk a cup of eggs will be broken, stirred. When the milk (powdered milk can also be mixed) boiled, pouring people eggs, rolled up to close the fire. Note that you can not eat raw eggs, because raw eggs are not easy to be digested and absorbed by the body. Don't cook the eggs old, because eating too much boiled protein food, not only taste bad, not easy to digest and absorb, more importantly, it can make the body's calcium metabolism abnormality, will also cause calcium deficiency. In addition, you should pay attention to not put sugar, because eating too much sugar can also cause imbalance of calcium metabolism in the body, lower blood calcium. If you want to eat sweet, put some honey is better. Eggs and milk are good for nutrition, rich in protein, fat, inorganic salts and vitamins. Inorganic salts are rich in calcium and phosphorus, vitamin A, B1, B2, etc., and the protein contained has all the essential amino acids. These substances play a role in the nutrition of intraocular muscles, sclera, retina, optic nerve and other tissues. Through nutrition, can enhance the strength of the ciliary muscle and sclera toughness.
2. wolfberry meat ingredients: wolfberry 100 grams of lean pork 300 grams of green bamboo shoots (or yucca slices) 10 grams of lard 100 grams of another stir-fry vegetables and condiments in moderation production: the lean pork washed, cut into 6 centimeters or so of the filaments, green bamboo shoots, the same production, the wolfberry washed. When the oil is seventy percent hot, the next person meat, bamboo shoots stir fry, add wine, soy sauce, salt, monosodium glutamate, put the wolfberry, stir fry a few times, pouring people sesame oil can be. Description: wolfberry can nourish the liver and kidney, moist lung and eyesight. Pork is rich in protein, by tonifying the body, so that the qi and blood, in order to nourish the tissues within the eye.
3. Pork liver soup ingredients: 100 grams of pork liver 2 eggs black beans, white onion, salt, monosodium glutamate moderate production: pork liver washed, cut into slices. Place in a pot with the right amount of water, cook over low heat until the liver is cooked, add black beans, white onion, and then beat the egg, add salt, monosodium glutamate and other flavoring. Note: Eggs and pig liver are protein-rich food. Pork liver contains more vitamin A, which can nourish the eyeballs, and receive the effect of nourishing the liver and brightening the eyes, which is suitable for children and adolescents with myopia (also used in the dietary treatment of farsightedness). The pig liver can be replaced by sheep liver, beef liver, chicken liver.
4. chicken liver soup ingredients: chicken liver 50 grams of salt, monosodium glutamate, ginger production: chicken liver washed and chopped, cut into slices, blanch into the boiling water, until the chicken liver discoloration bloodless when taken out, take advantage of the situation to add the ginger, salt, monosodium glutamate, mixing can be. Description of chicken liver in the highest content of vitamin A, this party can nourish the liver and eyesight, suitable for all kinds of myopia.
