Astigmatism

The distortion of light as it passes through the cornea is known as Astigmatism. The astigmatic eye has a cornea which is not perfectly smooth and spherical, with equal curvature on all sides. Because the astigmatic eye is not round, but shaped more like a football, there is a distortion or tilting of images due to asymmetric bending of light rays. It is correctable with corrective lenses and, in some cases, laser vision correction may be an option.
