Zithini iimpawu ze-astigmatism?
Iimpawu eziqhelekileyo ze-astigmatism zezi:
- Umbono ofipheleyo
- Kufuneka ujonge phantsi ukuze ubone ngokucacileyo
- Intloko ebuhlungu
- Uxinzelelo lwamehlo

Ukuba une-astigmatism encinci, usenokungaziboni iimpawu. Yiyo loo nto kubalulekile ukuba uhlolwe amehlo rhoqo —iUgqirha wakho angakunceda uqinisekise ukuba ubona ngokucacileyo kangangoko. Oku kuyinyani ngakumbi kubantwana, abasenokungaqondi ukuba umbono wabo awuqhelekanga.
Yintoni ebangela i-astigmatism?
I-Astigmatism yenzeka xa i-cornea okanye ilensi yakho inesimo esahlukileyo kunesesiqhelo. Le milo yenza ukukhanya kugobe ngendlela eyahlukileyo njengoko kungena elisweni lakho, nto leyo ebangela impazamo yokuchasana nokukhanya.
Oogqirha abazi ukuba yintoni ebangela i-astigmatism, kwaye akukho ndlela yokuyithintela. Abanye abantu bazalwa bene-astigmatism, kodwa abantu abaninzi bayikhula besebancinci okanye besebancinci. Abanye abantu banokuba ne-astigmatism emva kokwenzakala kweliso okanye utyando lweliso.
Ithini indlela yonyango lwe-astigmatism?
Eyona ndlela ixhaphakileyo yonyango lwe-astigmatism ziiglasi zamehlo.Iugqirha wamehlosbaza kukunika iilensi ezifanelekileyo ukukunceda ubone ngokucacileyo kangangoko kunokwenzeka. Oogqirha banokusebenzisa utyando ukunyanga i-astigmatism.
