Diagnosing Astigmati: Astigmatism is caused by a football shaped cornea so technologies can that can measure corneal shape (topographers) can diagnose astigmatism.Glasses refraction, corneal topography, scheimpflug photography, keratometry, and many sophisticated technologies can easily diagnose astigmatism today. Most cases can be corrected by glasses/cls, laser techniquesand lens implant technologies (toric lenses).

Astigmatism: A complete eye exam can pick up astigmatism, since it is measurable in your glasses prescription. It can also be mapped using corneal topography, where a surface is made of your eyes.

Irregular Cornea: Astigmatism usually is caused by an irregularly shaped cornea. Instead of the cornea having a symmetrically round shape (like a baseball), it is shaped more like a football, with one meridian being significantly more curved than the meridian perpendicular to it. Astigmatism usually causes vision to be blurred or distorted to some degree at all distances.

You cannot: With the exception of certain eye diseases, most people's prescription, including astigmatism, is stable from the early 20s to the middle to late 40s and sometimes beyond. You can correct for this with glasses, contacts or laser vision correction.
