Astigmatism

Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped.

An irregularly shaped cornea 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.  This can lead to eye discomfort and headaches.

Most people have some degree of astigmatism. Slight astigmatism usually doesn’t affect vision or require treatment.

Astigmatism frequently occurs with other vision conditions like myopia (nearsightedness) and hyperopia (farsightedness). Together these vision conditions are referred to as refractive errors because they affect how eyes bend or “refract” light.

The specific cause of astigmatism is unknown. It can be hereditary and is usually present from birth. It can decrease or increase over time.

A comprehensive optometric examination will include testing for astigmatism. If necessary, your optometrist can provide eyeglasses or contact lenses that correct astigmatism by altering the way light enters the eyes.

Laser surgery can also treat some types of astigmatism. The laser changes the shape of the cornea by removing a small amount of the eye tissue.
