Astigmatism is a refractive error triggered when your cornea or lens have an uneven curve. This mismatch triggers light that enters your eye to be curved erratically, which can cause blurred vision in any way distances. Most people who have astigmatism are born with it, yet some may get it from eye injuries, diseases or surgical treatment.

Misconception 4: Astigmatism is painful
The eye is created 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 blurred. This refractive error can be fixed with prescription eyeglasses and also contact lenses or by having astigmatic keratotomy surgical treatment, which entails making little cuts on the steepest curves of the cornea.
