Astigmatism What is an astigmatism? Astigmatism is a refractive error caused by an imperfection of the curvature of your eye. This occurs when the cornea or lens has an irregular shape, instead of a smooth and normal curvature. As a result, light rays entering the eye will not bend properly causing the light rays not to focus properly on the retina. This causes blurred or distorted vision at any distance. It is unknown what causes astigmatism, but it is thought to be heredity. Most people are thought to be born with it. However, this is not always the case. An astigmatism is fairly mild eye disorder in which may not require you to have any symptoms or any treatments.
