Astigmatism

Astigmatism affects vision at both distance and near.  The front surface of the eye(cornea) or the lens inside the eye is irregular in shape causing the light rays entering the eye to come to focus at two different points and result in blurred vision.  It is a common refractive error, just like nearsightedness and farsightedness.  Eyeglasses and contact lenses are used to correct for astigmatism.
