Astigmatism

In astigmatism, the shape of the cornea more closely resembles that of an American football than a soccer ball. Astigmatism occurs when the cornea or lens is more curved in one direction (axis) than in the other. In astigmatism, the shape of the cornea more closely resembles that of an American football than a soccer ball.

Light rays coming from objects focus at different points (in front of and/or behind the retina) instead of at one point. This results in blurry vision both at a distance and up close. Astigmatism is more common in infants and children and may run in families. It can be associated with other eye problems that may be detected during an eye examination.

Cylindrical eyeglass lenses are prescribed for astigmatism to improve vision. Contact lenses and laser surgery are alternatives to glasses for adults.
