What causes astigmatism in children's eyes?

Astigmatism is one of the manifestations of eye refractive error. There are many reasons for astigmatism in children's eyes. Congenital corneal refractive error, corneal lesions, trauma, incorrect eye use, long time watching electronic screens and other reasons may cause astigmatism. If the child's astigmatism is severe, take the child to the hospital for optometry examination in time, and let the child wear glasses with appropriate power for correction.
