During outdoor activities, the eyes will automatically adjust to see things at different distances, and the eyes will be used alternately from far to near, so that the ciliary muscles of the eyes can be adjusted without feeling tired. Nowadays, many parents mostly let their children play at home due to inconvenient factors such as work.

If children in this age group do not get enough sleep, the sympathetic and parasympathetic nerves will become dysfunctional, resulting in dysfunction of the ciliary muscle regulation. Getting 9-11 hours of sleep every night will protect your eyesight.
