Astigmatism

Astigmatism is that condition wherein the refraction varies in different meridians of the eye. It occurs when light entering the eye is "split" into two separate parts instead of focusing on one precise point on the retina. Astigmatism is commonly caused by abnormalities in the curvature of the cornea. If you are astigmatic, you will experience a distortion or blurring of images at all distances, nearby, as well as distant.
