How to know if i have astigmatism?

Astigmatism: It's hard to know if you have astigmatism without an eye exam. Astigmatism is one type of refractive error. Myopia (or nearsightedness), hyperopa (or farsightedness), and astigmatism all can cause refractive error which is what causes a patient to require glasses or contact lenses to see better. Astigmatism is typically when the cornea is shaped more like a football than a basketball.

Get tested: Astigmatism is the term for an eye which has some degree of ovalness. This distorts the vision to the degree that the astigmatism is strong. Correction is a reverse oval in the glasses or contacts. It is common and not a big deal. Your ophthalmologist can easily test you for this and if you wear eyeglasses, you can ask the optical shop to check them and tell you if there is any astigmatism.

Get examined: If you have a significant amount of astigmatism your vision will be blurry. See your eye doctor for a refraction to find out for sure.
