Astigmatism

Share this

Astigmatism is a condition in which objects, both near and distant, appear blurred. The cornea and lens of the eye should be spherical. When one or both are curved more steeply in one meridian than another, the optics take on a toric shape (like a football). This uneven curvature prevents light rays entering the eye from focusing to a single point on the retina, blurring the visual image somewhat like a funhouse mirror at an amusement park. Astigmatism often occurs in combination with myopia and hyperopia.

Signs and Symptoms

Blurred vision of near and distant objects; eyestrain and fatigue

Related Eye Conditions

Myopia (nearsightedness)
Hyperopia

Treatment

Eyeglasses, contact lenses, incisional refractive surgery or laser vision correction procedures
