Misconception 4: Astigmatism hurts
The eye is developed to filter light into the retina and also focus it onto the rear of the eye (the cornea or lens). When these structures are misshapen, however, vision can be blurred. This refractive error can be fixed with prescription spectacles and contact lenses or by having astigmatic keratotomy surgical treatment, which involves making small cuts on the steepest contours of the cornea.
