In most cases, the astigmatism is caused by disorders of the cornea shape.In astigmatism both distant, and near objects appear distorted.This is due to the curvature of the cornea, which is more oval than circular, resulting in an inability to focus rays of light on the same plane.

Diagnosis

Astigmatism is often diagnosed with a simple measurement of the person’s visual acuity carried out by an eye specialist.
