Myth 4: Astigmatism is painful
The eye is designed to filter light into the retina and focus it onto the rear of the eye (the cornea or lens). When these structures are misshapen, however, vision can be blurry. This refractive mistake can be corrected with prescription glasses and also contact lenses or by having astigmatic keratotomy surgical treatment, which includes making little cuts on the steepest contours of the cornea.
