In a relaxed state, the parallel light passes through the refractive system of the eyeball and focuses in front of the retina, which is called myopia. Myopia is also called shortsightedness, because this kind of eye can only see near but not far. When the eye is resting, the parallel light from the infinite distance, after passing through the refraction system of the eye, gathers in front of the retina to form a focus, and forms an unclear image on the retina. The far vision is obviously reduced, but the near vision is still normal. There are many factors that cause myopia, one is genetic factor, the other is acquired external factor. Here we mainly explain the way to alleviate myopia caused by acquired factors.

(1) Relax:

① Mydriasis therapy: mydriasis with cycloplegia is used. At present, eye drops are given once a day.

2. Convex lens method: first let the patient wear a convex lens with a higher degree, watch the vision meter 5 meters away, relax the ciliary muscle, then adjust the degree of the convex lens, so that the eyesight is basically normal.

③ Overlooking method: after studying or writing for 1-2 hours, you can overlook the natural scenery and relax the ciliary muscles. Keep on doing eye exercises 3-4 times a day.

(2) To improve the excitability and visual function of the visual center:

Direct current therapy for myopia, ear acupuncture, plum blossom acupuncture, acupoint massage, acupoint conduction, Qigong therapy and cold water bath therapy. It is mainly to increase the excitability of the brain's optic center and optic nerve cells, which can improve both the near and far vision.

(3) Improve learning environment: keep a distance of 30cm and correct posture when reading and writing. Pay attention to the natural light and ensure adequate lighting in the room. Combine work with rest, get rid of bad study habits, take a rest of 10-15 minutes every hour, do not lie or walk to read. Pay attention to physical exercise

Of course, there are many specific methods, such as:

1: Stand somewhere, find a distant tree and a closer tree, and then observe the trees near for a while, and then observe the trees far away for a while. This method has the function of adjusting eye muscles and relaxing. When observing, try to look at the details of the tree as much as possible

2: Rub your hands and cover your eyes. Do it again and again. It's relaxing and comfortable. You can do it anytime, anywhere.

3: Sunbathe, when the weather is clear, close your eyes, face the sun, let the light through the eyelids, stimulate the eye cells. Our nearsighted people are very sensitive to light. They will squint or squint when they encounter strong light. This can improve the ability of our eyes to accept light.

4: Sit or stand, look straight ahead first, then move your eyes up, down, left and right, and stretch your eyes in each direction as much as you can, just for a few seconds in each direction. We will find that our eyes are deformed after myopia. This method can adjust our eyes back to normal shape and help to restore the focusing ability of the eyes.

5: More blinking, blinking can alleviate eye fatigue, this is to do at any time.

According to the above methods, combined with reasonable vision correction, I believe that you will feel that your eyesight has indeed improved after a period of time. My friends have tried it for a month, and the eyesight has dropped from the original 400 to 300 degrees. He is still insisting. Listening to him, the effect is very good. You may as well try it.

At the press conference of the leading group for epidemic prevention and control in Shanghai, it was announced that senior three and junior three of the city would return to school on April 27, and all colleges and secondary vocational schools could arrange the return of graduating students from April 27. All kinds of schools at all levels shall make preparations for other sections and grades to return to school in batches before May 6.

During the epidemic, the time for students to start school has been delayed. At present, in addition to graduating students starting to return to school, a large number of students still have to continue online classes at home. During the online classes, children need to use mobile phones, computers and iPads. For children, watching electronic screens for a long time will produce eyes for children in the growth and development stage Great harm, causing eye fatigue, near vision loss and other consequences.

As a result, Dr. Hua Haimei, director of Nutrition Department of pediatric hospital affiliated to Fudan University, specially prepared a scientific diet and eye protection book for parents and children during online classes.

According to Dr. Hua Haimei, the following nutrients and foods rich in these nutrients have a protective effect on children's eyes. Parents are suggested to supplement more nutrients for children during online classes.

1、 Provitamin A and vitamin A

Vitamin A is an important raw material for the formation of eye photosensitive substances. Vitamin A is sufficient, which can increase the smoothness of the cornea and make the eyes bright and vivid. There are two main forms of vitamin A: Pro Vitamin A (mainly β - carotene from plants) and formed vitamin A.

Beta carotene can be converted into vitamin A in the body. Therefore, fruits and vegetables containing β - carotene are good sources of vitamin A.

Vitamin A from animal food mainly exists in animal liver, cod liver oil, eggs, milk and their products; β - carotene and various carotenoids from plant food mainly exist in green leaf vegetables, yellow vegetables and fruits, such as broccoli, pea seedlings, spinach, carrots, sweet potatoes, Lycium, etc. Vitamin A contained in animal food or supplements is the formed vitamin A. if it is over supplemented, it will cause more poisoning than the original vitamin A contained in plant food.

2、 Carotenoids (lutein and zeaxanthin)

In the carotenoid family, only zeaxanthin and lutein exist in the retina of the eye. They can absorb the blue light that strongly damages the retina, protect the retina from damage, and keep the vision sensitive and clear. Foods rich in lutein include spinach, broccoli, onion, amaranth, asparagus, rape, etc. The foods rich in zeaxanthin include corn, pumpkin, orange, spinach, mustard, etc.

3、 Anthocyanin

Anthocyanin can strengthen capillaries, stabilize the microvasculature of eyes, and enhance the circulation of microvasculature. In addition, anthocyanin is also a strong antioxidant, which can reduce the damage of free radicals to the eyes and improve vision. Rich in anthocyanins: blueberry, blackberry, strawberry, grape, cherry, purple radish, carrot, pomegranate, purple rice, etc.

4、 DHA

DHA (c22:6, n-3) is the most abundant polyunsaturated fatty acid in photoreceptors of retina, which is necessary to maintain the normal function of rhodopsin. However, we can not synthesize this fatty acid by ourselves. DHA supplementation will make the vision sharper and clearer. In addition, DHA is also an important component of brain neurons. Food rich in DHA: deep sea fish, such as salmon, salmon, etc.

5、 Zinc

It can promote the metabolism and physiological function of vitamin A, and help to maintain visual health. If there is not enough zinc, it will lead to vision loss and blurred vision under low light. Zinc rich food: shellfish and mollusc seafood, animal liver, lean meat, black sesame, hazelnut, walnut, etc.

6、 Vitamin E

Vitamin E has a strong antioxidant, it can reduce the free radicals in the eyeball, play a role in protecting the eyes. Foods rich in vitamin E: all kinds of vegetable oil, nuts, beans and seafood, etc.

7、 Vitamin C

Vitamin C can prevent the retina from being damaged by ultraviolet rays, prevent the lens from aging, increase the toughness of small blood vessels in the eyes, repair cells, and help improve the health of the eyes. Vitamin C mainly comes from fresh fruits and vegetables. Generally, dark vegetables, oranges, grapefruits, kiwifruit, fresh dates, grapefruits, green peppers, strawberries and other contents are high. The preservation time and cooking methods of vegetables and fruits have different degrees of damage to vitamin C.

8、 Vitamin B2 (riboflavin)

Riboflavin is a coenzyme of many flavinases in the body, which is widely involved in the redox reaction in the body. If riboflavin is deficient, the conjunctival congestion, shame, blurred vision and other symptoms will occur. The main sources of riboflavin are eggs, lean meat, milk, beans and cereals.

Dr. Hua Haimei reminded that although food has the effect of protecting eyesight, children must remember that the maintenance of good eyesight is to pay attention to eye hygiene at ordinary times, so that food can really protect our eyesight.

The college entrance examination is over. We can relax completely! Although the college entrance examination is over, but the protection of our eyesight can never be relaxed. Myopia and bad eye habits are related to a certain extent. In the same way, bad eating habits can also become accomplices to induce myopia. To prevent myopia and keep away from the problems brought by myopia, we might as well start with eating first. These six kinds of food are eye protectors.

1. Vitamin A

Vitamin A plays an important role in the formation of human vision and participates in the synthesis of rhodopsin in retina. Lack of vitamin A will affect the adaptability of eyes in the dark environment, which is manifested as decrease, and even lead to night blindness. The foods with high vitamin a content include animal liver, cod liver oil, roe, whole milk and whole milk products, eggs, etc.

Carotene can be converted into vitamin A in human body, which is also called vitamin a source. Spinach, leek, pea seedling, alfalfa, green pepper, sweet potato, carrot, pumpkin, apricot, mango and other vitamin A sources are more.

2. Calcium rich food

Calcium is also known as the "protector" of eye tissue. If there is a lack of calcium in the body, it will lead to the decrease of the elasticity of the eye retina, the increase of the pressure in the crystalline body, the lengthening of the anterior and posterior diameter of the eyeball, and may also lead to the pathological changes of the cornea and ciliary muscles, so as to easily lead to vision loss or myopia.

The foods rich in calcium include milk, beans, fungi, dried fruits and marine products, and they can be used with vitamin D to help calcium absorption.

3. Foods rich in vitamin C

Persimmon pepper, tomato, lemon, kiwifruit, hawthorn and so on are rich in vitamin C. vitamin C can weaken the damage of light and oxygen to the lens of the eye and delay the occurrence of cataract.

4. Trace elements

Microelements mainly include selenium, zinc, chromium, etc., which can improve the function of eye tissue and prevent vision loss. Animal liver, egg, fish, shellfish, soybean, mushroom, asparagus, shepherd's purse, carrot, etc. contain more selenium; liver, kidney, seafood, milk, cereal, beans, hard fruit, etc. contain more zinc; beef, black pepper, brown rice, corn, millet, coarse flour, brown sugar, grape juice, edible fungus, etc. contain more chromium.

5. Kelp

In addition to iodine, mannitol contains one third of the "status" in kelp. There will be a layer of "white frost" on the surface of dried kelp, namely mannitol. Its effect is to reduce intraocular pressure, so it is helpful for the treatment of glaucoma. Seaweed products, such as Undaria pinnatifida, also contain mannitol, which is an adjuvant treatment for glaucoma.

6. Coarse grain and fresh vegetables

Most of the time, we advocate eating more coarse grains and fresh vegetables, because they contain vitamin B and vitamin C, which can play a role in eye protection.

Don't pay attention to these three points. Look out for myopia

1. Too sweet

Eat too much sweets, will consume a lot of vitamin B1 in the body, but also reduce the calcium in the body, weaken the elasticity of the eye wall, induce myopia.

2. Eating too well

The reason why eating too well is not good. This is because eating too well for a long time, especially for children, will lead to the lack of trace element chromium in their body, which will lead to the lens becoming convex, the diopter increasing, and induce myopia.

3. Eating too soft

Eating too soft is not good, it is reported that too little hard food intake is also one of the causes of juvenile myopia.

Nowadays, people use computers and mobile phones more and more. For a long time, playing and working without limit will cause our eyes to feel itchy, slight pain, vision loss and blurring. Therefore, it is very important to properly maintain our eyes. How to protect our eyes in daily life?

1. Take buckwheat skin, mung bean skin, black bean skin, cassia seed and chrysanthemum. The medicine is finely mixed and evenly mixed. It is put into a cloth bag to make a pillow. The pillow is covered with plastic bag and taken off at night. We have a clear vision.

2. This prescription is fumigated and washed with liquid medicine for external use. It can directly affect the eyes, increase the metabolism of the eyes, promote the blood circulation, and is very beneficial to the health care of the eyes. Wash Mungbean and chenjing rice and put them into the pot. Add 1000ml of water. Cook them into congee in high heat and low heat first, then put them into liver slices. The liver is cooked. Take it three times a day.

3. 2 chicken livers, 100g rice, a little salt. Chop the chicken liver and cook it with rice as porridge. When it is cooked, mix in salt and take it twice in the morning and evening. This prescription can increase the vision, especially for night blindness and people with dazzling eyes.

4. 120 g of Cistanche deserticola, 60 g of Morinda officinalis, 60 g of chrysanthemum and 60 g of Lycium barbarum. The 4 flavours are dried and dried together, and the white wax is used as a pill, such as Wutong. Take 15g / day, twice a day, dilute salt and boiled water. Our side is full of essence and bright moon, which is suitable for fainting.

5. This is the Cixi recipe proposed by Zhang Zhongzhi, a royal doctor of Qing Dynasty. It can be used as a daily health care prescription for eyes. 9 g for chamomile, 9 g for frost mulberry leaf, 3 G for mint, 1.5 g for antelope horn tip, 9 g for raw land and Prunella vulgaris. Pan fried, smoked and washed.

Daily eye care tips

1. When reading, whether it is physical books, e-books, computer screens, mobile phones or tablets, the light should be sufficient and have enough distance. It is recommended to take a rest every 30 minutes, close your eyes or look at distant scenery.

2. More outdoor activities, such as playing ball, and looking at distant scenery. Because outdoor activities involve focusing far and near and moving focus in all directions, the eye muscles can take the opportunity to relax and tighten.

3. You should wear sunglasses for outdoor activities. It is ideal to have UV400 degrees to completely block the UV, and you can also wear a hat, especially when the sun is strong at 12 noon. It is found that people who work outdoors and are exposed to sunlight but do not take corresponding eye protection measures will suffer from cataracts, wing flesh, macular degeneration and other problems earlier than ordinary people.

4. Do not rub your eyes often. Wash your hands frequently to reduce infection.

5. It's easy for computer workers to dry their eyes for a long time. When they need it, they can drop preservative free artificial tears and blink in the distance. Sometimes, when we focus on the computer screen, the number of blinks will decrease and lead to dry eyes. We found that the lower part of the cornea was very dry. The reason was that the eyelid was opened before it was completely covered, so that the tears were not enough to moisten the eyes.

6. If you find eye spots, blindfold, eye pain or dry eyes, you should see an ophthalmologist to check them out. If you have red eyes, you have the chance to have an eye infection, you must seek medical advice as soon as possible. You should not buy eyedrops randomly.

These prescriptions listed above will relieve our tired eyes to a certain extent. In addition, the most important thing is that when we read books or use computers in our daily life, we should adjust our suitable luminosity, and always wear sunglasses and other protective measures for outdoor sports.
