Yintoni i-altigmatism?
I-Astigmatism yingxaki yeliso eliqhelekileyo enokwenza umbono wakho ogqwethekileyo okanye ugqwetha. Kwenzeka xa i-cornea yakho (i-suble yangaphambili yeliso lakho) okanye i-lens (inxenye yangaphakathi yeliso lakho elinceda ekugxilwe kuyo ngamehlo) linendawo eyahlukileyo kunesiqhelo.
Ekuphela kwendlela yokufumanisa ukuba une-astigmatism kukufumana uvavanyo lwamehlo. Iiglasi zamehlo okanye iilensi zonxibelelwano zinokukunceda ubone ngcono - kwaye abanye abantu banokufumana utyando ukulungisa i-astigmatism yabo.
Zithini iimpawu zokuphambana?
Ezona mpawu ziqhelekileyo ze-atigmatism zezi:
- Umbono we-blurry
- Ndifuna i-squint ukuze ubone ngokucacileyo
- Intloko
- Iliso lamehlo
- Ingxaki yokubona ebusuku
Ukuba unayo i-atigmatism ye-atigmatism, awunakujonga naziphi na iimpawu. Yiyo loo nto kubalulekile ukufumana iimviwo zamehlo rhoqo -iUgqirha unokukunceda uqiniseke ukuba uyabona ngokucacileyo. Oku kuyinyani ngakumbi kubantwana, abanokuthi bangabi lula ukuba baqonde ukuba umbono wabo awuqhelekanga.

Oogqirha abazi ukubangela ntoni ukuba ngubani unolwazi, kwaye akukho ndlela yokuthintela. Abanye abantu bazalwa bene-aligmatism, kodwa abantu abaninzi bayayikhulisa njengabantwana okanye abantu abadala abancinci. Abanye abantu banokuhlakulela ukungakhathali emva kokulimala kwamehlo okanye utyando kwamehlo.
Luthini unyango lwe-altigmatism?
