• How does the astigmatism affect vision?

  Astigmatism refers to an abnormal, elliptical shaping of the front surface of the human eye, or cornea. Although it is part of the larger group of eye conditions known as refractive errors, a category that includes the more commonly known ailments of nearsightedness and farsightedness, astigmatism is neither a disease nor a certain cause of vision problems. Only in cases where the curvature of the cornea is severe enough to prevent the human eye from focusing in on light rays will corrective lenses possibly be required. Unlike nearsightedness or farsightedness, someone with severe astigmatism will experience distorted or blurred vision at both close and long range. They may also suffer from headaches, fatigue and other discomfort as a result of the abnormal curvature. Source: http://www.sophisticatededge.com/does-astigmatism-affect-vision.html
