Most people have some degree of astigmatism — a vision condition that occurs when the front surface of your eye — the cornea — is slightly irregular in shape. This irregular shape prevents light from focusing properly on the back of your eye — the retina. As a result, your vision may be blurred. People with severe astigmatism will usually have blurred or distorted vision at all distances, while those with mild astigmatism may experience headaches, eye strain, fatigue or blurred vision at certain distances.

 

The good news is that almost all levels of astigmatism can be optically corrected with properly prescribed and fitted eyeglasses and/or contact lenses. Corneal modification is also a treatment option for some patients. A comprehensive optometric examination will include testing to diagnose astigmatism and determine the degree.
