Similarly one may ask, how does an astigmatism affect your vision?

Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye. As a result, vision becomes blurred at any distance. This can lead to eye discomfort and headaches.

How can you tell if you have astigmatism?

The diagnosis of astigmatism is easily made during the course of a complete eye examination. Astigmatism is detected by your eye doctor (ophthalmologist) by either checking your need for glasses (refraction) or actually measuring the curvature of the front of the cornea by using a keratometer or corneal topographer.
