Full Answer

Astigmatism is a common condition caused by either an irregularly shaped cornea or lens in the eye. This irregularity prevents light from focusing properly on the retina, the light-sensitive surface at the back of the eye, according to the American Optometric Association.

Slight astigmatism doesn't cause vision problems and doesn't require treatment. More severe astigmatism causes distorted or blurred vision, as well as eye discomfort or headaches. A comprehensive eye examination can determine the degree of astigmatism and what treatment, if any, is appropriate, notes the American Optometric Association.
