Content writer-Stiles Linde

The condition of astigmatism can be tough to comprehend. It is a refractive mistake that can be existing from birth or create throughout childhood years or after eye injuries or surgical treatment.

The cornea and lens work to redouble light getting in the eyes into a solitary centerpiece on the retina. With astigmatism, light goes into the eye in 2 various locations and generates fuzzy or altered images.

Causes
Astigmatism is a refractive error, which implies that light entering the eye does not concentrate specifically on the back of the eye (the retina). The outcome is blurry vision.

Usually, the cornea and also lens refract light specifically to ensure that light signals are concentrated on the retina to produce clear, crisp photos in the mind.
