Astigmatism might require corrective lenses or glasses. At what level of astigmatism would I need help?
When blurred: Astigmatism is very common -- almost everyone has a little bit. It simply means that the cornea is not perfectly round, but rather has one steeper and one flatter curvature (like the side of a football rather than a basketball). People with more than 0.75diopters of astigmatism usually notice that images are blurred without glasses or contacts. ...Read more

Refractive error 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.

See your ophthalmologist. ...Read more
