1, work and rest, don't use eye fatigue.

Whether reading or writing, or watching mobile phones and computers, we should have principles, don't be too fascinated, and learn to combine work and rest. If you are tired of reading, you can close your eyes and do eye exercises. Don't rely too much on electronic products, just watch it for about an hour every day.

Step 2 do outdoor sports

Teenagers and children should not stay indoors all the time, but should do outdoor sports, get more sunshine and get in touch with nature. Physical education class is at school, but you have to go out without physical education class at home. Sunbathing can promote vitamin D synthesis, calcium absorption and height development. Contact with nature, look at the mountains and rivers, eyes and muscles can relax, not so nervous.

3. Pay attention to sitting posture and writing posture

The most important thing in adolescence is learning. Reading and writing occupy most of the time during the day. If you are sitting incorrectly, sitting askew, or hunched over, and your eyes are too close to the book, you will be prone to myopia after a long time. Teenagers should pay attention to the principle of "one punch, one foot and one inch", sit up straight, don't hunch over, have a punch distance from the table, a foot distance from the book and an inch distance from the pen tip. Teenagers should always pay attention to themselves, and parents and teachers should always urge them.

4. Eat more food that is good for your eyes.

Teenagers want to prevent myopia, but also make more efforts in diet and eat more food that is good for their eyes. Vitamin A can promote the development of retina and protect eyes. In daily life, you can eat more foods rich in vitamin A, such as milk, eggs, carrots, pig liver and so on. To reduce the intake of industrial sugar, eating too much sugar will affect vision development and increase the probability of myopia.

5. Develop regular work and rest habits

Teenagers and children should develop regular habits of work and rest, and go to bed early and get up early every day. Parents should implement this aspect. Some teenagers are still watching their mobile phones after turning off the lights, which hurts their eyes and makes them nearsighted after a long time. Sleep when you should, don't stay up late, especially don't stay up late playing with your mobile phone.
