With the development of modern science and technology, children need to touch the electronic screen for a long time in their daily life and study, which may have a negative impact on their eye health. Therefore, preventing myopia has become the focus of many parents' attention. The following are some precautions to prevent myopia.

1. Ensure enough outdoor activities. Studies have shown that regular outdoor activities can effectively prevent myopia, especially during strong light exposure. So parents should let their children do at least 1 hour outdoor activities every day.

2. Control the eye time to avoid prolonged contact with the electronic screen. Long-term contact with the electronic screen will not only make children's eyes tired, but also make their eyes tense for a long time, which is easy to cause myopia. Therefore, parents should control their children's contact time with the electronic screen, and let them rest for 10- 15 minutes every day to see the distance and relieve eye fatigue.

3. Ensure adequate sleep time. Sleep can promote eye metabolism and repair, which is beneficial to eye health. Therefore, parents should ensure that their children get enough sleep every day and stay up late at night, which is also very important to prevent myopia.

4. Ensure a reasonable eye environment. When studying or reading, you should choose a bright and soft environment. At the same time, it is necessary to ensure that the writing distance and screen distance are appropriate to avoid eyeball fatigue.

5. Eat scientifically. Children's physical health is closely related to eye health. Parents should pay attention to providing their children with various nutritious foods, such as fresh vegetables, fruits, fish and other foods that are beneficial to eye health.

6. Check your eyesight regularly. If children are found to have poor eyesight, blurred vision, eye fatigue, headache and other symptoms, parents should take their children to the hospital for examination in time so as to find and treat vision problems as soon as possible.

In short, prevention of myopia requires parents to start from various aspects, establish a healthy lifestyle and good eye habits, so as to effectively reduce the incidence of myopia and promote children's eye health.
