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.
It is found that increasing protein in diet and reducing carbohydrate supply can reduce or prevent the increase of myopia in adolescents with genetic background. So in order to avoid myopia, 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. Studies have shown that protein, calcium, phosphorus, carrots, bean sprouts, oranges, oranges, red dates, animal livers and other fruits and vegetables can be supplemented to prevent myopia.
Myopia diet therapy
Studies have proved that myopia has a considerable relationship with diet. To prevent myopia, we must pay attention to diet adjustment, otherwise the effect will not be great.
Eating less sugar and carbohydrate food or overcooking protein food will reduce the occurrence of myopia. Eating too much sugar will reduce the stock of trace element chromium in the body.
Excessive intake of overcooked protein foods will cause abnormal calcium metabolism in the body, leading to calcium deficiency. These two elements, chromium and calcium, directly affect the body's regulation of intraocular pressure. If the contents of chromium and calcium in the human body are in a normal balance, the intraocular pressure can be kept normal, thus preventing myopia.
So in the daily diet, eat less sugar and overcooked protein food. And pay attention to supplement the trace elements chromium and calcium in the body. Foods rich in chromium include beans, wheat, eggs, chicken, pork and butter. Foods rich in chromium and calcium can be reasonably added to the daily diet to prevent myopia through dietary adjustment.
Myopia is a kind of ametropia. There are two main reasons for myopia: internal cause and external cause. Internal cause refers to the heredity of myopia. External factors mainly include working environment and physical quality. The incidence of myopia is higher in cities than in rural areas, and the precision industry is higher than that in general industries, especially students and intellectuals.
Besides heredity, physical factors are mainly related to malnutrition. The lack of certain or some important nutrients in the process of eye growth and development makes the eyeball tissue more fragile. Under the influence of environmental factors, the sclera of the eyeball wall is easy to expand, thus lengthening the anterior and posterior axis of the eye and causing myopia. Most nearsighted children have the habit of eating snacks, picky eaters and partial eclipse. They eat mostly flour and rice and fast food, lacking nutrition or being more damaged. At the same time, their diet lacks high-quality protein food, such as milk, eggs, milk, fish, meat, chicken and coarse grains. The fewer kinds of food, 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 myopia patients have low blood calcium and vitamin A deficiency. Most adolescent myopia patients have low serum protein, low blood calcium and low hemoglobin. After suffering from myopia, you should supplement vitamins A, B, B and trace elements such as calcium, chromium and zinc, and eat less candy and high-sugar foods. If you eat too much sugar, the increase of blood sugar content will cause changes in aqueous humor and lens osmotic pressure. When the osmotic pressure of aqueous humor is lower than that of the lens, aqueous humor will enter the lens, causing the lens to bulge and cause myopia. Eating too much polysaccharide and high carbohydrate will reduce the elasticity of intraocular tissues, reduce the storage of trace element chromium, and make the axial length of eyes easy to grow. In addition, eating too much sugar will produce a lot of acid in the blood. Acid neutralizes with salts in the body, especially calcium salts, and decreases in the blood, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, lengthen the axial length of the eye, and also cause the occurrence and development of myopia.
In order to prevent the occurrence and development of myopia, the food selected by dietotherapy is mainly to supplement the necessary nutrients of ciliary muscle and sclera in the eye, enhance the muscle strength of ciliary muscle and help it restore its inherent function; Strengthen the toughness of sclera, enhance its resistance to the outside world and prevent it from expanding.
Myopia can supplement the following nutrients:
1. protein:
As far as sclera is concerned, it can be the tough shell of eyeball, because it contains many essential amino acids and constitutes a very strong fibrous tissue. Although the sclera has some toughness, its diameter is still weak in the front and back of the axis. Animal foods such as meat, fish, eggs and milk are not only rich in protein, but also contain all essential amino acids.
2. Calcium:
Calcium is the main component of bone and sclera. High calcium content plays an important role in strengthening the toughness of sclera. Animal bones such as cattle bones, pig bones and sheep bones in food are rich in calcium, which is easily absorbed and utilized by human body. Others, such as milk, bean products, dried shrimps, dried shrimps, eggs, rape, Chinese cabbage, peanuts and jujube, also contain more calcium.
3. Zinc:
Myopia patients generally lack chromium and zinc. Myopia patients should eat more foods with high zinc content. Foods such as soybean, almond, laver, kelp, mutton, yellow croaker, milk powder, tea, meat, beef, liver and so on contain more zinc and chromium, which can be increased appropriately.
Vitamins are essential nutrients for human body. Although the human body has little demand for them, they play an extremely important role in human material and energy metabolism. Vitamins A, B 1, B2, C and E should be properly supplemented when dietotherapy is used to treat myopia. Foods rich in vitamins include eggs, milk, meat, fish, liver and fresh fruits and vegetables. 5. Foods for nourishing liver and kidney These foods mainly include medlar, walnut, peanut, jujube, longan, honey, shrimp, fish, meat and eggs.
Introduce some methods to prevent and treat myopia:
1. Breakfast: eggs 1 ~ 2 cups of milk. Break the eggs and stir well. After the milk (milk powder can also be mixed with milk powder) is boiled, pour in the eggs, roll them up and turn off the heat. Be careful not to eat raw eggs, because raw eggs are not easily digested and absorbed by the human body. Don't overcook the eggs, because eating overcooked protein food not only tastes bad, but also is difficult to digest and absorb. More importantly, it will cause abnormal calcium metabolism and calcium deficiency in the body. In addition, be careful not to put sugar, because eating too much sugar will also cause imbalance of calcium metabolism in the body and decrease of blood calcium. If you want to eat sweets, you'd better put some honey. It shows that eggs and milk are good nutrients, and they are rich in protein, fat, inorganic salts and vitamins. Inorganic salts are rich in calcium, phosphorus, vitamins A, B 1, B2, etc. The protein contained in them has all the essential amino acids. These substances have a certain nutritional effect on intraocular muscles, sclera, retina and optic nerve. Nutrition can enhance the strength of ciliary muscle and the toughness of sclera.
2. Ingredients for shredded pork of Lycium barbarum: Lycium barbarum100g lean pork, 300g green bamboo shoots (or magnolia slices)10g lard100g and proper cooking seasoning: clean the lean pork, cut it into 6 cm filaments, and also make green bamboo shoots. Wash the Lycium barbarum .. When the oil is 70% hot, add shredded pork and bamboo shoots. Description: Lycium barbarum can nourish liver and kidney, moisten lung and improve eyesight. Pork is rich in protein, which can nourish the body, make qi and blood vigorous, and nourish eye tissues.
3. Pork liver soup Ingredients: pork liver100g egg, 2 lobster sauce, scallion, salt and monosodium glutamate. Suitable for production: pig liver is washed and sliced. Add a proper amount of water to the pot, cook on low heat until the liver is cooked, add lobster sauce and scallion, then add eggs, salt and monosodium glutamate to taste. Description: Eggs and pork liver are foods rich in protein. Pig liver contains more vitamin A, which can nourish eyeball and improve eyesight. Suitable for myopia children and adolescents (also used for diet therapy of hyperopia). Among them, pig liver can be replaced by sheep liver, bovine liver and chicken liver.
4. Chicken liver soup ingredients: 50 grams of chicken liver salt, monosodium glutamate and ginger. Appropriate production: chicken liver is washed and chopped, cut into pieces, blanched in boiling water, fished out when the chicken liver becomes discolored and bloodless, added with ginger powder, salt and monosodium glutamate, and mixed well. It shows that the content of vitamin A in chicken liver is the highest, which can nourish the liver and improve eyesight, and is suitable for all kinds of myopia.
