Effective methods to improve eyesight 1. Staring at the distance: find a grass or green tree 10 meter away: green is imaged in front of the retina because of the short wave length, which promotes the adjustment and relaxation of the eyes, relaxes the ciliary muscles of the eyes and reduces 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 eyesight drops badly. 2, crystal exercises ● 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. ● Find a scene 3 meters away and raise your left hand slightly above your eyes (about 30 cm). After seeing the hand prints on the palm of your hand, look at Qingyuan again, and move your eyes between them as quickly as possible, going back and forth 20 times. 3. Massage can be sitting 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 next to the inner canthus of both eyes), first press down and then squeeze up. 3. Rubbing Sibai Point: Press Sibai Point in the center of the cheek with your index finger (pointing straight down in the middle of the lower edge of the 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. Turn your eyes to improve your eyesight: sit on the bed or chair, turn your eyes left three times, then turn your eyes left three times and look straight ahead for a while. Turn it twice every morning and evening, without interruption, and stick to it for a long time, and you will see the effect. Four exercise methods to protect eyesight 1. Choose a quiet place in the blink of an eye, or sit or stand, relax yourself, get rid of other thoughts, 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 down to right, up, left and down again, and turn them counterclockwise for another 6 times. 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. Second, the eye breathing method chooses a place with fresh air, or sits or stands, relaxes the whole body, looks straight ahead, slowly inhales, then opens your eyes wide, pauses for a moment, then exhales the air slowly, then slowly closes your eyes, and does it for 9 times in a row. Third, the best way to burn your eyes is to sit and do it. Relax all over, close your eyes, and then quickly rub your palms. Cover your eyes with your hands when it is hot. When the heat dissipates, your hands suddenly take them away, and your eyes can't open. This can promote the blood circulation of the eyes and increase metabolism. Fourth, the eye washing method first disinfects the washbasin, pours warm water, adjusts the water temperature, puts the face into the water, opens your eyes in the water, moves the eyeball up and down, left and right for 9 times, and then rotates clockwise and counterclockwise for 9 times. At first, water will enter the eyes, making them feel uncomfortable, but with the rotation of the eyeball, the eyes will gradually feel comfortable. When doing this action, if you feel difficult to breathe, you might as well lift your face from the washbasin and take a deep breath outside. This method can wash away harmful substances and dust in the eyes, and is also effective for mild cataract, and can improve the degree of ametropia of astigmatism, hyperopia and myopia. 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 use their eyes too much to improve their eyesight choose health food? 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. Foods with eyesight improving function need to protect eyesight and prevent eye diseases in many ways, among which paying attention to nutrition also helps to improve eyesight. In the daily diet, foods that can improve vision are: (1) foods rich in vitamin A, which is 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 health foods include: (1) foods rich in vitamin A, such as Lycium barbarum 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.
