What Is Astigmatism?

Q:
What is astigmatism?

A:
Astigmatism is a kind of refractive error in the curvature of your eye, which will result in distorted and blurred vision at all distances. Often, astigmatism is present at birth and may occur at later stages of life in combination with nearsightedness or farsightedness.

Astigmatism occurs when either your cornea or lens is egg shaped with two mismatched curves. In this way, light rays aren’t bent properly, thereby causing a refractive error in your eye. The fundamental cause of astigmatism remains unclear, but it is believed to be partly related to genetics that causes abnormalities in the lens of the eye.
