Astigmatism is a common refractive error that may cause blurring of both distance and near vision. It is often combined with either myopia or hyperopia. People with astigmatism typically notice more blurring along a specific axis (vertical lines, horizontal lines or diagonals), they also often report eye fatigue symptoms.
Astigmatism is the result of the irregular curvature of the cornea or of a more oval shaped eyeball.
We encourage you to consult your local eye care specialist for more information.
