My child is in the first grade of primary school this year. He always squints when doing his homework. What's the matter?

When children have pseudomyopia or true myopia, they will unconsciously squint at things. This is because they can be imaged through small holes, which can reduce the interference of external light and make them see more clearly. However, reading books at close range for a long time will lead to eye ciliary muscle spasm, and then develop into true myopia or deepen myopia.

Here are some tips for protecting your eyes:

1. Develop good eye habits.

Pay attention to reading and writing posture, and don't forget the three ones. Knock your chest off the table, keep your eyes one foot away from the book and hold your pen one inch. At the same time, the "20-20-20" rule should be adopted, that is, if you use your eyes at close range for 20 minutes, you should move to 20 feet (> 6m) for at least 20 seconds.

2. Moderate use of electronic products

When using electronic products, follow the principle of "rather big than small, rather far than close", try to use larger screens as far apart as possible, and turn on soft background lights, without strong contrast between light sources. Even in eye protection mode, avoid using electronic products for a long time.

Do more outdoor activities

Many studies have proved that sunlight is beneficial to the synthesis of dopamine, which has a certain effect on controlling myopia. It is helpful to exercise outdoors for 2 hours every day.

4. Check as soon as possible

Children should be given a comprehensive eye health examination as soon as possible to eliminate the risk of myopia and other eye diseases, so as to achieve early detection, early intervention and early treatment.
