1, distant gaze:
Find a place 10 meters away from the grass or green trees: green due to shorter wavelengths, imaging before the retina, prompting relaxation of ocular regulation, ocular ciliary muscle relaxation, reduce eyestrain. Don't squint, don't always blink, exclude distractions, concentrate, concentrate on the gaze for 25 seconds, recognize the outline of the 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 manipulation
● 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 massage points around the eyes in turn. Requirements for accurate acupuncture points, gentle techniques, in order to localize the feeling of soreness and swelling to the degree.
1. Knead the Tian Ying point: use both thumbs to gently knead 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 acupoint: use the forefinger to rub and press the Sibai acupoint (the lower margin of the eye socket in the middle of the straight down a cross finger) in the center of the cheeks.
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 corner of the eye backward at a cross finger), and then gently scrape the eye socket with the curved inner side of the second section of the forefinger, from the inner upper - & gt; outer upper - & gt; outer lower - & gt; lower, so that the orbital periphery of the save bamboo fish waist, the Silk Bamboo Air, pupil liao, after the ball, Cheng Sue and other acupoints are massaged. For pseudomyopia, or to prevent the deepening of myopia is beneficial.
Reference:
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 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), there were a lot of children 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 suffering from dry eye disease more and more. According to a survey by 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 tear layer, which contains substances that protect the eyes from infection, people blinking tears and then evenly distributed in the performance of 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, gastric 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 tear secretion of both eyes; 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 when 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 lot of vitamin B1. Every day, you can drink green tea, because of the lipopolysaccharide in the tea, can improve the hematopoietic function of the body, and 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, we need to remind you that when you are fully focused on the 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, the aqueous humor, lens and vitreous four parts of the transparent interstitial zigzagging of external light imaging in the retina of the reason. 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", it is the kelp in mannitol, mannitol has a diuretic effect, can reduce intraocular pressure, used in the treatment of acute glaucoma has good results. Other seaweeds such as wakame also contain mannitol, can also be used as a supplementary food for the treatment of acute glaucoma.
2. Health food to help improve vision Through diet can increase nutrition, improve vision, so we should consume more of the above foods, such as in the daily diet on the basis of the selection of appropriate health food with the function of improving vision, can play a good role in assisting 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.
