Astigmatism is a vision condition that causes blurred vision due either to the irregular shape of
the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye.
An irregular shaped cornea or lens prevents light from focusing properly on the retina, the light
sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance.
Astigmatism is a very common vision condition. Most people have some degree of astigmatism.
Slight amounts of astigmatism usually don’t affect vision and don’t require treatment. However,
larger amounts cause distorted or blurred vision, eye discomfort and headaches.
Persons with astigmatism have several options available to regain clear vision. They include:
• contact lenses
• laser and other refractive surgery procedures
