The condition of astigmatism can be difficult to realize. It is a refractive error that can be existing from birth or create during childhood or after eye injuries or surgical treatment.
The cornea and also lens job to refocus light entering the eyes into a solitary focal point on the retina. With astigmatism, light goes into the eye in two different places as well as produces fuzzy or altered photos.
Causes
Astigmatism is a refractive error, which indicates that light getting in the eye doesn't focus exactly on the back of the eye (the retina). The outcome is blurry vision.
