Astigmatism is a refractive error caused by the shape of either the cornea and/or the natural lens inside the eye. The cornea is the clear window on the front of every eye and the natural lens sits behind the iris or color part of your eye. If the cornea or lens is not perfectly round in shape but is more oval than this will cause the light to be blurred and unfocused at all distances.
Astigmatism rarely occurs alone and is typically accompanied by myopia or hyperopia, this is easily correctable with glasses and contact lenses. There are also refractive surgery options available to someone with astigmatism although they are slightly more limited. Be sure and ask Drs. Folwarski and Hayes any questions you may have about your options during your comprehensive eye examination.
