Astigmatism and Presbyopia

What Is Astigmatism?

Astigmatism is a common eye condition that ia easily corrected by eyeglasses, contact lenses or elective surgery.

Astigmatism is characterized by an irregular curvature of the cornea. This is one type of refractive error. Astigmatism occurs in nearly everybody to some degree. For significant curvature, correction is required.

A person's eye is naturally round in shape. Under normal circumstances, when light enters the eye, it bends evenly, creating a clear view of the object. However, the cornea of a person with astigmatism is shaped more like a football or the back of a spoon. For this person, when light enters the eye it is bent more in one direction than the other, allowing only part of the object to be in focus at one time. Objects at any distance can appear blurry.
