Astigmatism in children 5 years old is usually caused by congenital factors, and the child needs a dilated eye exam to clarify the refractive status. In this case, the child does not usually heal on his own. Astigmatism in children is a type of refractive error that often accompanies growth and is usually due to irregularities in corneal morphology. Astigmatism does not increase or decrease if the cornea is not diseased, so it does not heal on its own in children as young as 5 years old. 5 years old is a critical stage of visual development, and glasses are recommended regardless of the degree of astigmatism, otherwise it can cause amblyopia. It is recommended that the child visit the ophthalmology department of a regular hospital for examination and, depending on the specific cause, be treated by means of glasses and other methods. In daily life, parents should pay attention to children’s eye hygiene, prevent them from looking at electronic screens for a long time, and avoid excessive use of eyes. You can eat more foods rich in vitamin A and lutein.
