● IiLensi zoMbono omnye: Yintoni ilensi yombono omnye?
Xa kunzima ukugxila kwizinto ezikufutshane okanye ezikude, iilensi zombono omnye zinokunceda. Banganceda ukulungisa: Iimpazamo ezibonisa i-myopia kunye ne-presbyopia.
● Iilensi ezigxile kwizinto ezininzi:
Xa abantu benengxaki yombono ongaphezulu kwesinye, iilensi ezineendawo ekugxilwe kuzo ezininzi ziyafuneka. Ezi lens ziqulethe imiyalelo emibini okanye ngaphezulu yokulungiswa kombono. Izisombululo ziquka:
I-Bifocal lens: Le lens inokohlulwa ibe ngamacandelo amabini. Isiqingatha esiphezulu sinceda ukubona izinto ezikude, kwaye isiqingatha esisezantsi sinceda ukubona izinto ezikufutshane. I-Bifocals inokunceda abantu abangaphezu kweminyaka engama-40 abaphethwe yi-presbyopia. I-Presbyopia ekhokelela ekunciphiseni okuqhubekayo kokukwazi ukugxila kwimigama ekufutshane.
Ilensi eqhubela phambili: Olu hlobo lwelensi lune-lens enedigri etshintsha kancinci kancinci phakathi kwedigri ezahlukeneyo zelensi, okanye igradient eqhubekayo. I-lens ngokuthe ngcembe ingena kwingqwalasela njengoko ujonge phantsi. Kufana neeglasi ze-bifocal ezingenazo imigca ebonakalayo kwiilensi. Abanye abantu bafumanisa ukuba iilensi eziqhubekayo zibangela ukugqwetheka ngakumbi kunezinye iindidi zeelensi. Oku kungenxa yokuba indawo eninzi yelensi isetyenziselwa inguqu phakathi kweelensi zamagunya ahlukeneyo, kwaye indawo ekugxilwe kuyo incinci.
Ezi lens ziyanceda ukuba unengxaki yokugxila kwizinto ezikufutshane okanye ezikude. Iilensi ezinombono omnye zinokulungisa:
● I-Myopia.
● I-Hyperopia.
● Presbyopia.
Iiglasi zokufunda luhlobo lwelensi yombono omnye. Ngokuqhelekileyo, abantu abane-presbyopia babona izinto ezikude ngokucacileyo kodwa banenkathazo yokubona amagama xa befunda. Ukufunda iiglasi kunokunceda. Ungadla ngokuzithenga kwikhawuntara kwikhemesti okanye kwivenkile yeencwadi, kodwa uya kufumana ilensi echaneke ngakumbi ukuba ubona umboneleli wezempilo ukuze ufumane incwadi kagqirha. Ngaphezulu kwekhawuntara abafundi abancedi ukuba amehlo asekunene nasekhohlo anemimiselo eyahlukileyo. Ngaphambi kokuzama ukusebenzisa abafundi, jonga ingcali yakho yokhathalelo lwamehlo kuqala ukuze uqiniseke ukuba unokuzisebenzisa ngokukhuselekileyo.
Ukuba unengxaki yombono ongaphezulu kwesinye, unokufuna iiglasi ezineelensi ezininzi. Ezi lens ziqulethe imiyalelo emibini okanye ngaphezulu yokulungisa umbono. Umboneleli wakho uya kuxoxa ngeenketho zakho nawe. Ukhetho lubandakanya:
✔ Ii-Bifocals: Ezi lens lolona didi luqhelekileyo lwee-multifocals. Ilensi inamacandelo amabini. Indawo engasentla ikunceda ubone izinto ezikude, kwaye indawo engezantsi ikuvumela ukuba ubone izinto ezikufutshane. I-Bifocals inokunceda abantu abangaphezu kweminyaka engama-40 abane-presbyopia, ebangela ukwehla kokukwazi kwakho ukugxila kufutshane.
✔ Ii-Trifocals: Ezi glasi zamehlo zi-bifocals ezinecandelo lesithathu. Icandelo lesithathu linceda abantu abanengxaki yokubona izinto ezikufuphi nengalo.
✔ Iyaqhubela phambili: Olu hlobo lwelensi lune-lens etyekeleyo, okanye i-gradient eqhubekayo, phakathi kwamandla ahlukeneyo elensi. I-lens igxininisa ngokuthe ngcembe njengoko ujonge phantsi kuyo. Kufana ne-bifocals okanye i-trifocals ngaphandle kwemigca ebonakalayo kwiilensi. Abanye abantu bafumanisa ukuba iilensi eziqhubekayo zibangela ukugqwetheka ngakumbi kunezinye iindidi. Kungenxa yokuba indawo eninzi yelensi isetyenziselwa ukutshintshela phakathi kweentlobo ezahlukeneyo zeelensi. Iindawo ekugxilwe kuzo zincinci.
✔ Iiglasi zekhompyutha: Ezi lensi ezininzi zinezilungiso ezenzelwe abantu abafuna ukugxila kwizikrini zekhompyutha. Bakunceda ukuba uphephe ubunzima bamehlo.
