Astigmatism is a common optical condition which results in blurry vision (and, if uncorrected, sometimes a headache, eyestrain). It results when the curve of your cornea is slightly irregular in shape, which prevents light from focusing properly on the back of the eye (retina). This prevents you from seeing with perfect sharpness. The good news: A pair of eyeglasses and contact lenses can help compensate for astigmatism.
