With astigmatism, light goes into the eye in two various locations as well as generates fuzzy or altered pictures.

Causes
Astigmatism is a refractive mistake, which means that light getting in the eye does not concentrate exactly on the back of the eye (the retina). The outcome is blurry vision.

Typically, the cornea and lens refract light precisely to make sure that light signals are concentrated on the retina to generate clear, crisp pictures in the brain.
