Misconception 1: Astigmatism is caused by scrunching up your eyes
Unlike many eye problems, astigmatism is not caused by scrunching up your eyes. Rather, it's the outcome of abnormalities in the eye's cornea as well as lens that bring about fuzzy vision.
Normally, the cornea and lens at the front of your eye have a round shape that allows light to focus dramatically on the retina at the back of your eyeball.

It affects grownups and also youngsters alike.
Myth 2: Astigmatism is a genetic problem
Astigmatism is a refractive error caused when your cornea or lens have an uneven curve.

Other alternatives include orthokeratology, which makes use of inflexible get in touch with lenses to improve the cornea, or laser surgical treatment.
Myth 4: Astigmatism hurts
The eye is created to filter light into the retina and also focus it onto the rear of the eye (the cornea or lens). When these frameworks are misshapen, nonetheless, vision can be blurred. This refractive mistake can be remedied with prescription spectacles and also contact lenses or by having astigmatic keratotomy surgery, which entails making little cuts on the steepest curves of the cornea.
