The cornea and also lens job to refocus light entering the eyes right into a solitary centerpiece on the retina. With astigmatism, light gets in the eye in two different locations and also produces blurred or distorted pictures.

Causes
Astigmatism is a refractive error, which implies that light going into the eye does not concentrate exactly on the back of the eye (the retina). The outcome is blurry vision.

Normally, the cornea and lens refract light precisely so that light signals are concentrated on the retina to create clear, crisp pictures in the brain. Yet with astigmatism, the cornea or lens aren't flawlessly bent. Instead, they are much more like a ball or a Football with steeper as well as flatter sides.

People typically have astigmatism their whole lives, yet it's safe. It can be identified during a thorough eye examination.
