Misconception 4: Astigmatism hurts
The eye is developed to filter light into the retina and also concentrate it onto the back of the eye (the cornea or lens). When these frameworks are misshapen, nonetheless, vision can be blurry. This refractive mistake can be fixed with prescription spectacles and contact lenses or by having astigmatic keratotomy surgery, which entails making tiny cuts on the steepest contours of the cornea.
