Article written by-Boye Gilbert

The problem of astigmatism can be hard to comprehend. It is a refractive mistake that can be present from birth or develop throughout childhood or after eye injuries or surgical procedure.

The cornea and lens job to refocus light entering the eyes into a solitary centerpiece on the retina. With https://blogfreely.net/wilmer51britt/frequently-asked-questions-concerning-lasik-surgery , light enters the eye in 2 various places and also creates fuzzy or distorted photos.

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

Typically, the cornea as well as lens refract light precisely to make sure that light signals are concentrated on the retina to produce clear, crisp pictures in the mind. However with astigmatism, the cornea or lens aren't completely rounded. Instead, they are a lot more like a ball or an American football with steeper and flatter sides.

People normally have astigmatism their whole lives, however it's safe. It can be found during a thorough eye test.
