Ukuba ukhetha ukunxiba iilensi zokunxibelelana endaweni yeeglasi ukuphucula umbono wakho, kukho iindidi ezininzi onokukhetha kuzo.
Zombini iilensi zoqhagamshelwano eziqinileyo nezithambileyo zineengenelo kunye nokungalungi kwazo.Yiyiphi eyona ifanelekileyo kuwe inokuxhomekeka kwiimfuno zakho zombono, indlela yokuphila, kunye nezinto ozikhethayo.
Ukuba uqwalasela iilensi ezinzima, funda ukuze ufunde malunga neenzuzo kunye neengozi zezi lensi kunye nendlela yokuzisebenzisa ngokukhuselekileyo.

IiLensi zoQhagamshelwano eziMbala kagqirha
Olona hlobo luqhelekileyo lusetyenziswayo lweelensi eziqinileyo ziilensi zegesi ezivuzayo (RGP).Zikhululekile kwaye zikhuseleke ngakumbi ukunxiba kuneentlobo zangaphambili zeelensi eziqinileyo njengelensi zepolymethyl methacrylate (PMMA) zemveli.Iilensi ze-PMMA azifane zisetyenziswe namhlanje.
Iilensi ze-RGP zenziwe ngezinto zeplastiki eziguquguqukayo ezihlala zine-silicone.Ezi zinto zikhaphukhaphu zivumela ioksijini ukuba idlule ngokuthe ngqo kwi-lens ukuya kwi-cornea yeliso.
I-cornea yakho ngowona maleko wangaphandle ocacileyo weliso lakho.I-cornea yakho ikhupha ukukhanya kwaye isebenza njenge-lens engaphandle yeliso lakho.Xa i-cornea ingafumani ioksijini yaneleyo, iyadumba.Oku kunokukhokelela ekuboneni luzizi okanye luzizi, kunye nezinye iingxaki zombono.
Iilensi ze-PMMA azivumeli ioksijini ukuba idlule kwiilensi.Ekuphela kwendlela ioksijini enokufikelela ngayo kwi-cornea kukuphuma kweenyembezi phantsi kwelensi ngalo lonke ixesha uqhwanyaza.
Ukuvumela iinyembezi ukuba ziphume phantsi kwelensi, iilensi ze-PMMA zincinci kakhulu.Kufuneka kwakhona kubekho umsantsa phakathi kwe-lens kunye ne-cornea.Oku kwenza iilensi ze-PMMA zingakhululeki ukunxitywa kwaye iilensi zinokuwa, ngakumbi ngexesha lokuzilolonga.
Ekubeni iilensi ze-RGP zivumela i-oksijini ukuba idlule, ezi lens zikhulu kune-PMMA lens kwaye zigubungela uninzi lwamehlo.
Ukongeza, imiphetho yeelensi ze-RGP zinamathela ngokusondeleyo kumphezulu wamehlo akho.Oku kubenza bakhululeke ngakumbi ukunxiba kuneemodeli ezindala.Ikwavumela iilensi ukuba zihlale emehlweni akho ngokukhuselekileyo.
Iimpazamo ze-refractive zenzeka xa imilo yeliso lakho ithintela ukukhanya okungenayo ukuba kugxile ngokufanelekileyo kwi-retina.Iretina ngumaleko wezicubu ezingevayo kukukhanya ngasemva kweliso.
Ukunxiba iilensi zoqhagamshelwano eziqinileyo ze-RGP kunokulungisa iintlobo ezininzi zeempazamo zokuphinda ziphinde zisebenze, kuquka:
Iilensi zoqhagamshelwano eziqinileyo ze-RGP zineenzuzo ezininzi kwiilensi zoqhagamshelwano ezithambileyo.Makhe sijonge ezi zibonelelo ngokweenkcukacha ngakumbi:
Iilensi ze-RGP ezinzima zoqhagamshelwano nazo zineengxaki ezithile.Nazi ezinye iingxaki eziqhelekileyo ngezi lensi.
Ukuba ufuna iilensi zakho zoqhagamshelwano eziqinileyo zihlale ixesha elide, kubalulekile ukuba uzikhathalele.Ukhathalelo olufanelekileyo lwelensi lunokunciphisa umngcipheko wokosuleleka kwamehlo okanye imikrwelo ye-cornea.
I-rigid gas permeable lens (RGP) lolona hlobo luxhaphakileyo lweelensi eziqinileyo ezimiselweyo namhlanje.Ngokuqhelekileyo zibonelela ngombono ocacileyo kunee-lens ezithambileyo.Zikwahlala ixesha elide ekuhambeni kwexesha kwaye ngokuqhelekileyo azibizi kakhulu kuneelensi ezithambileyo.
Ukongezelela, ezinye iimeko, kubandakanywa ne-astigmatism, zinokulungiswa ngokufanelekileyo kunye neelensi zokudibanisa ezinzima.

IiLensi zoQhagamshelwano eziMbala kagqirha
Nangona kunjalo, iilensi eziqinileyo zihlala zithatha ixesha elide ukuziqhelanisa kwaye zisenokungakhululeki njengeelensi zokudibanisa ezithambileyo.Thetha nogqirha wakho wamehlo ukufumanisa ukuba loluphi uhlobo lwelensi yoqhagamshelwano olulungele wena kunye neemfuno zakho zombono.
Masihambe phezu kwezinto ezisisiseko zokuthenga iilensi zoqhagamshelwano ezinemibala kwi-intanethi kunye neenketho ezintlanu zokuzama ukuze ukwazi ukuthenga ngokuzithemba.
Ukuqubha ngeelensi zoqhagamshelwano kunokukunceda ubone ngcono, kodwa konyusa umngcipheko wakho weengxaki zamehlo, ukusuka kwamehlo omileyo ukuya kunzulu…
