Myopia can't**, but it can be prevented. If children and adolescents can develop good eye habits, reduce the use of electronic products, and increase outdoor activity time, they can completely prevent and avoid the occurrence of myopia. Its main practices include:

1.Develop good eye habits.

01 Reading and writing posture should be correct: the "three ones" should be achieved in reading and writing, that is, the distance between the eyes and the book should be kept at least one foot, the distance between the chest and the desk should be about one fist, and the distance between the fingers holding the pen and the tip of the pen should be about one inch.

02 Intermittent eye use, combination of work and rest: 10 minutes of rest after 40 minutes of reading and writing time.

First of all, be sure to use your eyes to standardize!! Strictly follow the doctor's advice, keep a long-term distance between your eyes and objects, especially electronic products, even if you are reading a book, you should not be too short apart, and do not stare at a book in bright light. Secondly, learn to loosen the bindings of your eyes!

For example, give a break after long-term eye use, look into the distance or do a simple eye care exercise. Finally, it is recommended to check the eyesight and eye condition in one cycle, and then adjust it appropriately.

Ways to prevent myopia and protect eyesight: 1. Eye movement method, when the head is rotated up, down, left and right, the eyes also rotate together. 2. Blink method.

Tilt your head back and blink your eyes to get the blood flowing, and when your eyes are slightly tired, you only need to do it 2-3 times. 3. Alternate hot and cold compresses. Use two towels, one moistened with hot water and one damp with cold water, first place the hot towel on your eyes for about 5 minutes, then put the cold towel on for 5 minutes.

4. Eye gymnastics. The middle finger is pointed between the eye socket and the bridge of the nose, rub the palm of the hand over the face back and forth for 5 minutes, then slowly move the neck to the left and right, then close the eyes, clench the fist and tap the back of the neck ten times. 5. Look far and look near.

Look into the distance for 3 minutes, then look at the palm of your hand for 1-2 minutes, and then look into the distance, so that you can effectively eliminate eye fatigue by alternating several times.

Do eye exercises every day, don't watch computers, mobile phones, TVs and other electronic products for a long time.

1. Prevent eye infections.

1.Avoid rubbing your eyes with dirty hands: Because children are more active and full of curiosity about the outside world, when exploring the unknown world, their hands will be contaminated with many germs, so we must develop the habit of washing hands frequently, and tell children not to rub their eyes with dirty hands, so as not to get infected and cause myopia.

2.Pay attention to the health of the water park: The water park business in summer is very hot, and many parents will take their babies to play in the water, but if the hygiene of the pool is not up to standard, the child plays in such water for a long time, which may cause infection and hurt the eyes, so when you take your child to play, you must pay attention to the choice and do not go to the water where the hygiene is not up to standard.

2. Educate children to learn eye hygiene.

1.The posture of reading and writing should be correct: the child's posture must be correct when reading and writing, the upper body should sit upright, the head should not be crooked, let alone leaning forward, and the distance between the eyes and the book should be maintained at about one foot.

2.Avoid excessive eye fatigue: Do not let children use their eyes for a long time, generally read and study for about 40 minutes and then take a 10-minute rest, let children look at the distance or look at green plants, etc., to relieve eye fatigue.

3.Avoid watching TV for a long time: Because the light of the TV is very damaging to the eyes, do not let children watch TV for a long time, watch TV for half an hour should take a break of 15 minutes, and the distance between people and the TV should be more than one meter.

It is best not to let children play with electronic products, so as not to hurt the eyes and develop myopia.

3. Develop good eating habits.

When there is a lack of vitamins, it will cause eye diseases, so it is necessary to pay attention to let children eat more vitamin-rich foods such as fruits, vegetables, pig liver, sheep liver, etc., to nourish the liver and eyes, which can effectively prevent myopia.

If you want to avoid myopia, you must clearly understand what are the causes of myopia and how to prevent myopia effectively, efficiently and scientifically.

First, long-term, close-range flat content (plane fixation) is the main cause of myopia, reading, watching TV, playing with mobile phones, watching computers, etc. Long-term near-plane fixation will make the ciliary muscle unable to adjust the lens, the contraction and relaxation function of the ciliary muscle, the adjustment ability will be reduced, the elasticity of the lens will deteriorate, and over time, the lens will become convex, the eye axis will become longer, and eventually our vision will deteriorate, thus forming myopia.

Second, it is necessary to reduce long-term and close-range plane fixation, pay attention to intermittent rest of both eyes, and do more 3D visual training, rice exercises, and eye exercises to alleviate visual fatigue. In addition, proper outdoor exercise, soft light, adequate sleep time, correct writing and reading posture, maintaining balanced nutrition, and regularly going to the hospital or professional institution for vision examinations are all important precautions for the prevention and control of myopia.

Third, you can use 3D vision training or visual training for vision prevention and control protection, the country has actually carried out naked-eye 3D technology into the campus myopia prevention and control work, the use of stereoscopic glasses-free 3D technology for dynamic binocular vision function examination and 3D vision training, more accurate, more intuitive understanding of students' vision and myopia prevention and control. The data shows that the vision of students who participate in 3D vision training is significantly improved and protected, and the children's myopia is effectively improved.
