Reasons
Astigmatism is a refractive error, which means that light going into the eye doesn't concentrate precisely on the back of the eye (the retina). The result is fuzzy vision.

Generally, the cornea as well as lens refract light precisely to ensure that light signals are concentrated on the retina to create clear, crisp photos in the mind. But with astigmatism, the cornea or lens aren't completely curved. Rather, they are extra like a sphere or a Football with steeper and also flatter sides.
