Content author-Stiles Linde

The problem of astigmatism can be tough to comprehend. It is a refractive mistake that can be present from birth or establish during childhood years or after eye injuries or surgery.

The cornea as well as lens work to redouble light entering the eyes right into a solitary focal point on the retina. With astigmatism, light goes into the eye in two various areas as well as generates blurred or distorted images.

Causes
Astigmatism is a refractive error, which indicates that light getting in the eye doesn't focus precisely on the back of the eye (the retina). The outcome is fuzzy vision.

Usually, the cornea and lens refract light specifically to make sure that light signals are focused on the retina to create clear, crisp photos in the brain.
