The condition of astigmatism can be difficult to grasp. It is a refractive mistake that can be existing from birth or create during childhood or after eye injuries or surgical treatment.

The cornea and also lens work to refocus light going into the eyes right into a solitary prime focus on the retina. With astigmatism, light enters the eye in two various areas and produces fuzzy or distorted photos.

Reasons
Astigmatism is a refractive mistake, which implies that light getting in the eye doesn't focus precisely on the back of the eye (the retina). The result is blurred vision.
