Eye mishapend: astigmatism is when the eye or its structures are not round (spherical). It commonly is on the cornes but may be in the lens or the shape of the eye itself.

Irregular Cornea: Astigmatism usually is caused by an irregularly shaped cornea. Instead of the cornea having a symmetrically round shape (like a baseball), it is shaped more like a football, with one meridian being significantly more curved than the meridian perpendicular to it. Astigmatism usually causes vision to be blurred or distorted to some degree at all distances.

Oval eye shape: Refractive errors require either plus (farsighted) or minus (nearsighted) glasses + an extra amount if the eye is oval in shape (astigmatism). These are called refractive errors and can be corrected with glasses or contacts. The list of other eye problems is long and these are usually unrelated to astigmatism.
