Astigmatism of 75 degrees is classified as mild astigmatism by classification standards, and this condition does not usually affect vision and usually does not need to be treated. Therefore, children with 75 degrees of astigmatism is not too serious, and if it does not cause vision loss, it does not need to be treated, and does not need to wear glasses. And computerized optometry itself has different degrees of error, and this result may also be brought about by machine error. However, if the child appears after this situation, it is recommended to take the child to the hospital regularly to do vision check and optometry check, generally every six months or so to check the situation, each check to do a comparison, if it has been maintained in this state there is no problem, but if the degree is more and more obvious or vision loss, to correct early.
