This implies that the light entering your eye strikes the retina at more than one point, which results in fuzzy or altered vision. The other kind of astigmatism is uneven astigmatism, which means that your cornea and/or lens are bent in more than one direction or steeper in all-time low than the top.

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