A child with 175 diopters of astigmatism is not really serious in terms of the number of diopters, but it is also important to differentiate between the type of astigmatism and the vision that the child has when he or she is not wearing glasses. If it is a conformal type of astigmatism, 175 diopters tends not to affect vision too much, and the vision may be in the range of 0.7 or 0.6 or so, then it is not serious. If it’s with glasses, the vision can improve up and the child accepts the astigmatism glasses better. If the astigmatism is oblique or retro-axial, 175 diopters is relatively serious. Because oblique axis astigmatism and inverse astigmatism have a greater impact on vision, the vision without glasses may only be 0.3 or 0.4, in this case it is necessary to wear glasses, and the eyes may need to adapt to 1-2 weeks to be able to accept. Because some children may be a little dizzy or see things distorted when they first wear glasses, but they should still try to wear them to ensure good corrected vision.
