Astigmatism is not a disease; it is simply a type of refractive error or vision condition, which causes blurry, fuzzy or distorted vision. Astigmatism is a condition caused by subtle flaws in the way your eye bends light (a process called refraction ) that passes to the retina, the light-sensitive area at the back of the eyeball. The optic nerve transmits nerve impulses from the retina to the brain, which translates them into eyesight. If your vision works properly, your cornea and the lens behind it refract light into the retina. Alas, imperfe ...
