The condition of astigmatism can be hard to realize. It is a refractive mistake that can be present from birth or develop during childhood or after eye injuries or surgical procedure.

The cornea as well as lens work to redouble light entering the eyes right into a solitary centerpiece on the retina. With astigmatism, light enters the eye in 2 various places and also creates blurry or altered images.

Reasons
Astigmatism is a refractive error, which implies that light going into the eye doesn't focus exactly on the back of the eye (the retina). The result is fuzzy vision.

Normally, the cornea and also lens refract light specifically to make sure that light signals are concentrated on the retina to generate clear, crisp pictures in the mind.
