If astigmatism is present in a six-month-old child after an optometric examination, whether it can be restored depends on the severity of the astigmatism. Because the child’s cornea is in the process of development, if there is a mild astigmatism, for example, within 100 degrees, it is mostly caused by the irregular development of the cornea, so as the child grows older and the cornea gradually normalizes, this astigmatism may gradually disappear and return to normal. Even if the astigmatism persists for a long time, it will not affect the child’s vision and does not need to be treated. However, if the astigmatism is very large, for example, more than 200 degrees, the child’s vision will be reduced and glasses will be required.
