Written by-Albertsen Gilbert

The problem of astigmatism can be hard to comprehend. It is a refractive error that can be existing from birth or develop throughout childhood years or after eye injuries or surgical treatment.

The cornea as well as lens work to redouble light going into the eyes into a single focal point on the retina. With Myopia , light enters the eye in two various areas and generates fuzzy or altered photos.

Reasons
Astigmatism is a refractive error, which indicates that light going into the eye doesn't concentrate exactly on the back of the eye (the retina). The outcome is blurred vision.
