Many people think that if they have an astigmatism, they have a special eye condition. However, astigmatism is a very common vision problem. An astigmatism is a refractive error in vision, just like being farsighted or nearsighted. It is caused by having an eye which is not shaped round or spherical, but more like an egg or football. This causes light to bend in different directions and not focus on the back of the eye properly. A recommendation for vision correction will be made, if you are found to have an astigmatism during your vision exam. Astigmatism is normally corrected with eyeglasses or contact lenses. Some patients may even get their astigmatism corrected with laser eye surgery.
