Training methods to protect and improve eyesight.
1. Staring at the distance:
Look for a piece of grass or green trees 10 meters away: green is imaged in front of the retina because of the short wave length, which can promote the adjustment and relaxation of the eyes, 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. 10 minutes, repeat 20 times, 3 times a day, and increase the training times for those with severe vision loss.
2. Crystal operation:
① Hold your chin with both hands, and let your eyes rotate 10 times in the order of up, down, left and right, and then rotate 10 times counterclockwise and clockwise respectively.
② Look for scenes 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.
① Kneading Tianying Point: Gently press Tianying Point (under the brow and in the upper corner outside the orbit) with two thumbs.
② Squeezing Jingming Point: Gently press Jingming Point with the thumb of one hand (the nose root is close to the inner canthus of both eyes), first pressing down and then pressing up.
③ Knead Sibai Point: Knead Sibai Point in the center of the cheek with your index finger (straight down to the middle of the lower edge of the orbit).
④ Scraping the eye socket by pressing the temple: press the temple with the thumb (pointing backwards between the brow tip and the outer corner of the eye), and then gently scrape the eye socket with the inner surface of the second section of the flexed index finger, from the inside up to the outside up to the outside down to the inside down, so that the acupuncture points around the eye socket such as the waist of the bamboo pole, the hollow bamboo pole, the pupil-dredging, the back of the ball and the weeping can be massaged. Conducive to pseudomyopia or prevent myopia from deepening.
2) Food to protect and improve eyesight.
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 weaken 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, lack of chromium is easy to cause myopia. Chromium can activate insulin and make islets exert the maximum biological effect. If the chromium content in human body is insufficient, it will hinder the function of insulin to regulate blood sugar, increase the osmotic pressure of plasma, lead to the osmotic pressure of eyeball lens and aqueous humor, and increase the diopter, thus inducing 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 can 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. Pearls, pearls contain more than 95% calcium carbonate and a small amount of minerals such as magnesium oxide and aluminum oxide, and contain 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.
