Astigmatism is a common ophthalmic disease, which is mainly caused by the change of corneal curvature. The cornea is the window in front of the eyeball, allowing light to enter our eyes, reflect to our brains and let us see the beautiful world. However, when the corneal curvature changes, the light cannot form a focus on the retina, resulting in astigmatism.

Regular astigmatism

Regular astigmatism is caused by the deviation of corneal curvature from its vertical direction in a certain direction. It can be caused by different refractive power of cornea, myopia and hyperopia, but it can be corrected by glasses.

Irregular astigmatism

Irregular astigmatism is mostly caused by congenital or acquired corneal diseases, trauma and other scars after healing. Mild astigmatism may not affect vision, but it may cause discomfort such as eye fatigue. Severe astigmatism may lead to headache, pain around the orbit, nausea, vomiting and other symptoms, affecting health and work. It is recommended to go to a professional optical shop or eye hospital for optometry in order to find and treat astigmatism in time.
