The problem of astigmatism can be hard to grasp. It is a refractive error that can be present from birth or establish throughout childhood or after eye injuries or surgical treatment.

The cornea and also lens job to redouble light entering the eyes right into a solitary prime focus on the retina. With astigmatism, light goes into the eye in 2 various places as well as generates fuzzy or altered images.

Reasons
Astigmatism is a refractive mistake, which implies that light entering the eye doesn't concentrate exactly on the back of the eye (the retina). The outcome is fuzzy vision.

Usually, the cornea and lens refract light exactly so that light signals are concentrated on the retina to produce clear, crisp photos in the brain. But with astigmatism, the cornea or lens aren't completely bent. Rather, they are more like a sphere or a Football with steeper as well as flatter sides.
