Yini ebangela i-astigmatism?
I-Astigmatism yenzeka lapho i-cornea noma ilensi yakho inesimo esihlukile kunesijwayelekile. Isimo senza ukukhanya kugobe ngendlela ehlukile njengoba kungena esweni lakho, okubangela iphutha lokubuyisa amehlo.
Odokotela abazi ukuthi yini ebangela i-astigmatism, futhi ayikho indlela yokuyivimbela. Abanye abantu bazalwa bene-astigmatism, kodwa abantu abaningi bayihlakulela beseyizingane noma besebancane. Abanye abantu bangase babe ne-astigmatism ngemva kokulimala kwamehlo noma ukuhlinzwa kwamehlo.
Iyini indlela yokwelapha i-astigmatism?
Izindlela zokwelapha ezivame kakhulu ze-astigmatism yizibuko zamehlo.Iudokotela wamehlosbazokunikeza amalensi afanele ukukusiza ukuthi ubone ngokucacile ngangokunokwenzeka. Odokotela bangasebenzisa nokuhlinzwa ukwelapha i-astigmatism. Ukuhlinzwa kushintsha ukuma kwe-cornea yakho ukuze ikwazi ukugxila kahle ekukhanyeni.Uma udinga usizo lokukhethakufanelekileizibuko zokuthuthukisa isimo samehlo akho, i-Universe Optical https://www.universeoptical.com/products/ uhlala ekulungele ukukunikezaokuningiizinketho kanyeisevisi ecatshangelwe kahle.
