What Is Astigmatism?

Astigmatism is a vision condition that causes blurred vision due to either the irregular shape of the cornea or sometimes the curvature of the lens inside the eye. Most people have some degree of astigmatism, but larger amounts can cause distorted or blurred vision, eye discomfort, and headaches.

Depending on the amount of astigmatism present, eyeglasses or contact lenses may be used for correction.
