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

The cornea and also lens work to refocus light going into the eyes right into a single prime focus on the retina. With astigmatism, light gets in the eye in 2 different places and also generates fuzzy or altered photos.

Causes
Astigmatism is a refractive mistake, which suggests that light entering the eye does not focus precisely on the back of the eye (the retina). The result is fuzzy vision.

Normally, the cornea and also lens refract light precisely so that light signals are focused on the retina to generate clear, crisp images in the mind. But with astigmatism, the cornea or lens aren't perfectly bent. Instead, they are much more like a round or a Football with steeper and flatter sides.
