To replenish the eyes of children, it is important to eat foods rich in vitamin A, such as carrots, pumpkin and oranges. At the same time, we should pay attention to avoid turning on the night light when going to sleep at night, and keep it dark. The key is to develop good eye hygiene habits on weekdays, such as cultivating a good posture for reading and writing; keeping the room well lit when reading, so that the ambient light is not too dark or too strong; not using your eyes for more than half an hour at a time; avoiding close-up eye use in the evening; not reading in a shaking car or other states; and watching TV for more than half an hour continuously. On weekdays, you should pay attention to wash towels frequently, as well as teach your baby not to rub his eyes with dirty hands, etc., and go to the hospital regularly for vision screening.
