Astigmatism is mainly caused by the fact that our corneas are not ideal spheres. In fact, most of us have more or less astigmatism, just to different degrees. For low astigmatism, if the vision is not affected and there is no visual fatigue, treatment is not necessary and regular review is sufficient. If astigmatism has an impact on vision or comfortable eye use, it needs to be corrected by wearing glasses to improve visual acuity and visual fatigue. High levels of astigmatism can lead to amblyopia in children, so glasses are needed to correct the resulting amblyopia. You can wear frame glasses or contact lenses. For those with stable refractive error in both eyes in adulthood, you can also consider corneal refractive surgery to correct astigmatism. Because of the complexity of astigmatism, astigmatism requires a professional doctor or optometrist to perform the optometry and prescription. After the doctor or optometrist has issued a prescription, experienced fitters and polishers are needed to process and handle the glasses. If the astigmatism or axial prescription is wrong, the child will not only be unable to achieve normal vision with such glasses, but will also be more likely to suffer from visual fatigue or have difficulty adapting. In addition, after the prescription is issued, the axial direction of the astigmatism lens must be correct in the process of making the glasses, otherwise new refractive errors will be created, which will bring about disturbing symptoms that are difficult to adapt to. In principle, all astigmatism should be corrected, but if the child cannot adapt after wearing glasses because the astigmatism is too high, he or she can wear low-degree corrective glasses first, and then wear high-degree corrective glasses after slowly adapting. The majority of people’s astigmatism is relatively stable and will not deepen or decrease in a short period of time, but with age, the astigmatism may change mildly or the direction of the astigmatism axis may change slightly. The treatment with glasses can correct the amblyopia caused by astigmatism, increase the clarity of vision and reduce the occurrence of visual fatigue, but will not reduce or disappear the child’s original astigmatism by wearing glasses. If the astigmatism changes significantly within a short period of time or the direction of the astigmatism changes significantly, it is important to pay attention to this, and careful examination is needed to rule out any pathology of the cornea or lens.
