Astigmatism is an irregular curvature of the front surface of the eye that results in blurred vision at all distances.

It is a common refractive error, just like nearsightedness and farsightedness. It is usually a condition from birth that progresses over time. Eyeglasses, contact lenses and refractive surgery are all effective treatments for astigmatism.
