What causes Astigmatism?
Astigmatism is generally the result of a misshapen cornea. Instead of being perfectly rounded (basketball shaped) the cornea more closely resembles a football or an egg shape. The misshapen cornea causes the eye to refract light in such a way that it produces 2 distorted images on the back of the eye, as opposed to one clear image.

How do I tell if I have Astigmatism?
An Eye examination is the best way to get an exact diagnosis. However, headaches, eyestrain and fatigue are very common symptoms as well. You may also notice blurred or distorted vision.

Can Astigmatism be treated?
Absolutely. With the corrective eyeglasses or premium contact lenses eye care doctors are able almost always to fully correct astigmatism.
