What is Astigmatism

Date:2021-09-17 Browse:1054

Astigmatism is caused by an irregularly shaped cornea. This results in blurred distance and/or near vision. A normal eye has a round cornea, shaped like a baseball. Light rays entering the eye focus at a single point on the retina, forming a clear image. An eye with astigmatism has an oblong-shaped cornea, shaped like an American football. As a result, the light rays do not focus on a single point on the retina. This causes blurred or distorted vision. Ask your eye doctor if you have corneal astigmatism.
