Myth 4: Astigmatism hurts
The eye is developed to filter light into the retina as well as concentrate it onto the rear of the eye (the cornea or lens). When these frameworks are misshapen, nonetheless, vision can be fuzzy. This refractive mistake can be fixed with prescription spectacles as well as get in touch with lenses or by having astigmatic keratotomy surgical treatment, which includes making small cuts on the steepest contours of the cornea.
