Astigmatism is a condition in which objects, both near and distant, appear blurred. The cornea and lens of the eye should be spherical(round). When one or both are curved more steeply in one meridian than another, the optics take on a toric shape (like a rugby ball). This uneven curvature prevents light rays entering the eye from focusing to a single point on the retina, blurring the visual image. Astigmatism may also occur in combination with near or farsightedness.
Signs and Symptoms
