Myth 4: Astigmatism is painful
The eye is made to filter light into the retina and focus it onto the rear of the eye (the cornea or lens). When these frameworks are misshapen, nevertheless, vision can be fuzzy. This refractive error can be fixed with prescription glasses and also contact lenses or by having astigmatic keratotomy surgery, which includes making tiny cuts on the steepest contours of the cornea.
