Astigmatism is when a person's cornea has a distorted shape. As you know that a normal cornea is shaped round like a ball, but the astigmatic eye has an irregularly shaped cornea. This situation causes an image to be focus on more than only a point on the retina, this will bring to blurred / fuzzy vision. It can be corrected by using eyeglasses or contact lenses, or even with laser surgery to reshape the cornea.
