Astigmatism is a defect in the curvature of your eye's cornea, or lens. When light enters the eye, it usually focuses on a single spot on the retina at the back of the eye. However, if the curvature of your cornea or lens is not symmetrical and not perfectly smooth, the light coming into your eye will focus in front of the retina, behind the retina, or multiple locations of both. This results in blurred or distorted vision at all distances.
