Astigmatism in children aged 5 years does not usually heal on its own, but is mainly caused by congenital factors. However, if astigmatism does not affect the child’s vision, no special treatment is needed, and timely correction is required when it does. Astigmatism in children is a common refractive error that is often present with their growth process and is mostly caused by congenital factors. Therefore, astigmatism in children as young as 5 years old does not usually heal on its own. However, because astigmatism is mild, it usually does not affect vision too much and therefore does not require special treatment. However, moderate to high astigmatism may cause amblyopia and therefore often needs to be treated by means of glasses, for example. In daily life, parents should pay attention to children’s eye hygiene, prevent them from looking at electronic screens for long periods of time, avoid overuse of eyes, and allow children to rest properly between reading or studying.
