1, eye movement method
Choose a quiet place, or sit or stand, relax, clear your mind, 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.
Step 2 blink
Tilt your head back and blink constantly to keep the blood flowing. When your eyes are slightly tired, you only need to blink 2~3 times.
3. Alternate cold and hot compress method
One towel is soaked in hot water slightly hotter than the bath water, and the other towel is soaked in cold water with ice cubes. Put the hot towel on your eyes for about five minutes, and then put the cold towel for five minutes.
4. Eye gymnastics
Point between the eye socket and the bridge of the nose, cover your face with your palm and rub it back and forth for five minutes. Then slowly move your neck from left to right, then close your eyes and pat the back of your neck ten times with your fist.
5. Look far, look close.
Look at the distance for three minutes, then look at the palm 1~2 minutes, then look at the distance. This exchange of distances for many times can effectively eliminate eye fatigue. Give it a try!
6, eye breathing concentration method
Choose a place with fresh air, or sit or stand, relax, look straight ahead, slowly inhale the air, then open your eyes wide, pause for a moment, then exhale the air slowly, then close your eyes slowly, and do it for 9 times in a row.
In order to prevent children from wearing glasses prematurely, in addition to providing rich protein and vitamins, the following foods are indispensable: 1. Calcium-containing food is a mineral element that we are familiar with and attach great importance to, but everyone's understanding of it focuses on promoting bone development and preventing rickets in children, and is rarely associated with eye development. However, medical experts point out that calcium deficiency is an important cause of poor vision and even myopia. Its scientific basis is that the eyeball is like a plastic bag filled with clear water. Without calcium, its "hydraulic pressure" will rise and fall, and it will not be able to maintain its normal state. This situation is like a light bulb, which is easily burned out by high and low voltages. If the eyeball lacks calcium, it will cause abnormal development and form myopia. Foods containing calcium include: milk, bean products, fish and shrimp, animal bones, etc. Moreover, we should pay attention to foods rich in vitamin D such as animal liver, egg yolk and green vegetables to increase the absorption and utilization of calcium. 2. Chromium-containing food is also an essential mineral element for human body. Its role in eyeball development is to keep its osmotic pressure balance, otherwise it will lead to lens bulging and convex lens, which will increase the diopter of the eye and become myopia. According to experts' calculations, children need about 50-200 micrograms of chromium every day. Chromium-containing foods include grains, meat, cheese and egg yolk. Therefore, children should arrange more. 3. Hard food often gives children some hard food, increasing the frequency and intensity of mouth stretching, which can promote the development of children's vision. A Japanese professor named Chuanyue made a special investigation for this purpose. According to the data, children who often eat soft foods such as pasta rarely use the masseter muscles of the chin, which is an important bane of abnormal vision. A study conducted by Teru Shimada, an associate professor in the Department of Health, Akita University, shows that students who often eat soft food but are not nervous often have poor eyesight. This is because mouth strain can increase the strength of facial muscles, including eye muscles, and make them have strong ability to adjust lenses and avoid myopia.
Hard foods suitable for children are carrots, fruits, cabbage, animal bones, beans and so on. These foods are very hard and nutritious, and they are especially recommended.
