Myth 2: Astigmatism is a hereditary condition
Astigmatism is a refractive mistake caused when your cornea or lens have an uneven curve.

Misconception 4: Astigmatism is painful
The eye is designed to filter light into the retina as well as concentrate it onto the rear of the eye (the cornea or lens). When these structures are misshapen, nevertheless, vision can be blurry. This refractive mistake can be corrected with prescription spectacles as well as get in touch with lenses or by having astigmatic keratotomy surgical procedure, which entails making tiny cuts on the steepest contours of the cornea.
