"Astigmatism occurs when the cornea is shaped more like an oblong rugby ball than a spherical football, which is the normal shape. In most astigmatic eyes, the oblong or oval shape causes light rays to focus on two points in the back of your eye, rather than on just one. This is because, like a football, an astigmatic cornea has a steeper curve and a flatter one."
