When the eye time is about 30 to 40 minutes, you can close your eyes to rest or look away, and then combine eye exercises to relax the eye muscles and let the tired vision have time to relieve.
The lighting conditions should be up to standardWhether your child is studying, reading or playing, as long as it is where you use your eyes, you must ensure sufficient light intensity.

In the cold winter, if the weather is better, you can go outdoors for more exercise, and many studies have shown that outdoor exercise for 2 hours or more a day may have a better effect on myopia prevention and control.
