It's caused by an imperfection in the cornea or lens of the eyes. Corneal astigmatism is when the cornea isn't evenly curved and smooth. Lenticular astigmatism is when the shape of the lens is distorted. Both conditions can be corrected by using toric contact lenses.<ref>{{Cite web\|url=https://misakicon.com/collections/astigmatism-toric-lenses\|title=Contact lens for Astigmatism\|last=\|first=\|date=\|website=Misaki\|url-status=live\|archive-url=\|archive-date=\|access-date=2019-12-21}}</ref> ==See also==
