1. Have a good environment, such as lighting, qualified printed matter, tables and chairs that meet your physiological height, and so on.

2. Develop good habits, keep the standard sight distance at ordinary times, and control the time of watching TV, operating computers and game machines; The visual distance of the eyes undergoing myopia correction surgery is generally 33cm, and the reading and writing posture should be correct; Avoid reading while lying down; Avoid reading while walking or riding a bike. Reading while lying down can't control the sight distance. If you are only ten centimeters away, your eyes need to be adjusted to 1000 degrees. So it is easy to be nearsighted.

3. Take physical exercise, increase outdoor activities, and keep your eyes moving outdoors. Reasonable diet and balanced nutrition.

I strongly recommend going to Xinhua Bookstore to buy the book Multidimensional Visual Training-A New Method to Correct Myopia, which was published by People's Health Publishing House in 2009. There are systematic eye exercises in it. I have to see them. If it is not available locally, I can buy a CD containing 16 yuan from Taobao (national unified price).

4. Pay attention to the computer light. It is best that the outside light is slightly stronger than the screen light, and the computer screen is slightly lower than the eye level. Remember that minors should not exceed one hour, and pay attention to rest their eyes.

5. Rest time, look farther and reduce visual fatigue. See things at a distance of five meters, not at close range. Look at something that is a little vague until you see it clearly. More than five minutes.

Multidimensional vision training was conducted among more than 20,000 students in more than 30 schools in Hangzhou from June 6 to April 2008. After testing, the vision control rate reached 33.3% and the vision improvement rate reached 49.7%. Have a good exercise. If you need more detailed questions and answers, you can send me an email.
