Myth 4: Astigmatism hurts
The eye is created to filter light into the retina and concentrate it onto the back of the eye (the cornea or lens). When these structures are misshapen, nonetheless, vision can be fuzzy. This refractive mistake can be remedied with prescription glasses and also contact lenses or by having astigmatic keratotomy surgery, which involves making little cuts on the steepest curves of the cornea.
