Iilensi eziqhubekekayo ezenziwe ngokwezifiso ezivelaI-Optical efanelekileyoZisisombululo sokujonga esilungiselelwe wena, esikumgangatho ophezulu esilungiselelwe iimfuno zombono zomsebenzisi ngamnye. Ngokungafaniyo neelensi eziqhelekileyo, iilensi eziqhubekekayo ngokwezifiso zibonelela ngotshintsho olugudileyo phakathi kombono okufutshane, ophakathi nowokude ngaphandle komgca ocacileyo wokwahlulwa, nto leyo ezenza zibe zilungele izigulana ezine-myopia kunye ne-presbyopia.
Ezona mpawu:
Ukulungiswa koMbono oHleliweyo:
Iilensi eziqhubekekayo ezenziwe ngokwezifisoingayilwa ukuze ivumelane nomyalelo okhethekileyo womntu oyinxibileyo, indlela yokuphila kunye neemfuno ezibonakalayo kwiintlobo ngeentlobo zobuso. Olu yilo olulungiselelwe wena ngokukhethekileyo lunciphisa ukugqwetheka kombono kwaye lubonelela ngamava okubona akhululekileyo nangokwendalo, alungiselelwe wena ngakumbi kuneelensi zemveli ze-multifocal.
Intuthuzelo Ephuculweyo kunye Nokuchaneka:
Nokuba umntu onxibe i-lens usebenza kwikhompyutha ixesha elide, esenza imisebenzi yangaphandle, okanye ufuna ukutshintsha umbono phakathi kwemigama eyahlukeneyo, iilensi eziqhubekekayo ngokwezifiso zinokuhlangabezana neemfuno zazo ezithile ngokusebenzisa iimilo zobuso ezahlukeneyo. Uyilo oluchanekileyo kunye nentuthuzelo ephezulu yeelensi zenza ukuba zibe lukhetho olufanelekileyo kubathengi abaxabisa ukusebenza kunye nentuthuzelo.
Ukudibanisa ubuhle kunye nomsebenzi:
Iilensi eziqhubekekayo ngokwezifiso zinenzuzo enkulu yokubonakala. Ngokungafaniyo neelensi ze-bifocal, ezineendawo ezijolise kuzo ezahlukeneyo, iilensi eziqhubekekayo ngokwezifiso zibonelela ngotshintsho olugudileyo phakathi kweendawo ezijolise kuzo, nto leyo ebonakala intle ngakumbi ngelixa kuthintelwa ukutsiba ngequbuliso embonweni obonwa ngeelensi ze-bifocal eziqhelekileyo.
Ngubani ofanele azisebenzise:
Iilensi eziqhubekekayo ngokwezifiso zilungele ngokukodwa abantu abane-presbyopia, abadla ngokuba ngaphezulu kweminyaka engama-40 ubudala kwaye banobunzima bokugxila kufutshane. Ziyindlela efanelekileyo kubantu abafuna ukulungiswa kokubona kodwa abafuna iilensi ezilungelelaniswe ngokugqibeleleyo neemfuno zabo zokubona. Iilensi eziqhubekekayo ngokwezifiso zikwanomtsalane kwabo bafuna ukuphepha umgca ocacileyo wokwahlula obonakala kwiilensi ze-bifocal.
Kubathengisi bezinto zokubona ezithengiswa ngobuninzi, abathengisi kunye neengcali zamehlo, iilensi eziphucukileyo ezenziwe ngokwezifiso aziphakamisi nje kuphela iimveliso zazo, kodwa zikwatsala abathengi abafuna intuthuzelo ephezulu kunye nokucaca okubonakalayo. Ngenxa yokuba ezi lensi zenzelwe umthengi ngamnye, zinokuba yimveliso ephezulu kakhulu kwisitokhwe, zinceda ukutsala abathengi abaqondayo ngakumbi abazimisele ngakumbi ukutyala imali kwimpilo yabo yokubona.
