Misconception 1: Astigmatism is triggered by scrunching up your eyes
Unlike most eye problems, astigmatism is not caused by squinting. Rather, it's the outcome of irregularities in the eye's cornea as well as lens that result in blurred vision.
Typically, the cornea and also lens at the front of your eye have a rounded form that enables light to concentrate greatly on the retina at the back of your eyeball.

Your eye doctor can recommend restorative glasses or get in touch with lenses to help you see plainly in all ranges. Astigmatism is among the most usual refractive errors that robs people of clear vision, together with nearsightedness (nearsightedness), hyperopia (farsightedness) and also presbyopia (aging blur). It influences adults and also youngsters alike.
Myth 2: Astigmatism is a genetic condition
Astigmatism is a refractive error caused when your cornea or lens have an irregular contour. This mismatch causes light that enters your eye to be bent unevenly, which can create blurred vision whatsoever distances. Most people that have actually astigmatism are born with it, yet some might get it from eye injuries, diseases or surgery.

This indicates that the light entering your eye strikes the retina at more than one point, which brings about blurry or altered vision.

The most usual treatment for astigmatism involves rehabilitative lenses, which can consist of glasses or get in touch with lenses. Various other alternatives consist of orthokeratology, which uses rigid contact lenses to improve the cornea, or laser surgical procedure.
Misconception 4: Astigmatism hurts
The eye is developed to filter light into the retina and concentrate it onto the back of the eye (the cornea or lens). When these frameworks are misshapen, nevertheless, vision can be fuzzy. This refractive mistake can be corrected with prescription glasses and also get in touch with lenses or by having astigmatic keratotomy surgical treatment, which involves making small cuts on the steepest curves of the cornea.
see post of the most typical sign of astigmatism is obscured vision, which can make it difficult to read or see things in the distance, also when you are sitting near them.
