Astigmatism 

Astigmatism occurs usually due to an irregularly shaped cornea, but can sometimes be due to an irregularly shaped lens. Astigmatic people suffer from distorted vision because their cornea has an oblong shape (Half of a Football) instead of a spherical shape (Half of a Baskeball). This causes light rays to focus on two points at the back of the eye, instead of just one. Astigmatism can occur alone or in conjunction with myopia or hyperopia. Astigmatism can be corrected with glasses, toric contact lenses, or refractive surgery.
