The condition of astigmatism can be difficult to comprehend. It is a refractive error that can be present from birth or establish throughout childhood years or after eye injuries or surgical procedure.

The cornea as well as lens job to refocus light entering the eyes into a solitary focal point on the retina. With astigmatism, light goes into the eye in 2 various areas as well as produces fuzzy or distorted photos.

Causes
Astigmatism is a refractive error, which indicates that light going into the eye does not focus specifically on the back of the eye (the retina). The result is blurred vision.

Normally, the cornea and lens refract light specifically to ensure that light signals are focused on the retina to produce clear, crisp pictures in the brain. But with astigmatism, the cornea or lens aren't completely curved. Instead, they are more like a ball or a Football with steeper and also flatter sides.
