IKwisithuba sebhlog yanamhlanje, siza kuhlola ingcamango yeelensi ze-flat top bifocal, ukufaneleka kwazo kubantu abahlukeneyo, kunye neengenelo kunye nokungalungi ezibonelela ngazo. Iilensi ze-flat top bifocal zikhethwa ngabantu abafuna ukulungiswa kokubona okukufutshane nokukude kwiglasi enye.
Isishwankathelo seeLensi zeFlat Top Bifocal:
Iilensi ezine-flat top bifocal luhlobo lwelensi ezine-multifocal ezidibanisa ukulungiswa kokubona kabini kwilensi enye. Ziqulathe inxalenye ecacileyo ephezulu yokujonga umgama kunye nenxalenye ecacileyo ethe tyaba kufutshane nezantsi yokujonga kufutshane. Olu yilo luvumela abasebenzisi ukuba babe notshintsho olungenamthungo phakathi kobude obuhlukeneyo be-focal ngaphandle kwesidingo seeglasi ezininzi.
Ukufaneleka Kwabantu Abahlukeneyo:
Iilensi ze-flat top bifocal zilungele abantu abane-presbyopia, ubunzima bendalo obunxulumene nobudala ekugxileni kwizinto ezikufutshane. I-Presbyopia idla ngokuchaphazela abantu abangaphezu kweminyaka engama-40 kwaye inokubangela ukuxinana kwamehlo kunye nokungaboni kakuhle kufutshane. Ngokudibanisa ukulungiswa kokubona kufutshane kunye nomgama, iilensi ze-flat top bifocal zibonelela ngesisombululo esisebenzayo kwaba bantu, zisusa ingxaki yokutshintsha phakathi kweeglasi ezahlukeneyo.
Iingenelo zeLensi zeBifocal eziBalaseleyo eziphezulu:
Ukulungela: Ngeelensi ezisicaba eziphezulu, abantu abanxibe iilensi banokonwabela ukubona izinto ezikufutshane nezikude ngokucacileyo ngaphandle kokutshintsha iiglasi. Oku kuluncedo ngakumbi kwabo batshintsha rhoqo phakathi kwemisebenzi efuna amanqanaba ahlukeneyo okubona.
Ixabiso eliphantsi: Ngokudibanisa imisebenzi yeelensi ezimbini zibe yinye, iilensi ezine-flat top bifocal zisusa isidingo sokuthenga iiglasi ezahlukeneyo ukuze ubone kufutshane nakude. Oku kuzenza zibe lukhetho oluphantsi kakhulu kubantu abane-presbyopia.
Ukuziqhelanisa: Bakuba beqhele iilensi ze-bifocal ezithe tyaba, abasebenzisi bazifumana zikhululekile kwaye kulula ukuziqhelanisa nazo. Ukutshintsha phakathi kweendawo ezikude nezikufutshane nokubona kuba lula ngokuhamba kwexesha.
Iingxaki zeLensi zeBifocal zeFlat Top:
Umbono ophakathi olinganiselweyo: Njengoko iilensi ezisicaba eziphezulu ezimbini zigxila kakhulu ekuboneni okukufutshane nokukude, indawo yokubona ephakathi (njengokujonga isikrini sekhompyutha) isenokungacaci kangako. Abantu abafuna umbono ophakathi obukhali banokufuna ukuqwalasela ezinye iindlela zelensi.
Umgca obonakalayo: Iilensi ezimbini eziphezulu ezithe tyaba zinomgca obonakalayo owahlula umgama kunye namacandelo akufutshane. Nangona lo mgca ungabonwa kangako ngabanye, abanye abantu banokukhetha ukubonakala okungenamthungo, becinga ngoyilo lweelensi ezizezinye ezifana neelensi eziqhubekekayo.
Iilensi ze-flat top bifocal zibonelela ngesisombululo esisebenzayo kubantu abane-presbyopia, zibonelela ngokubona okucacileyo kwezinto ezikufutshane nezikude kwiglasi enye. Nangona zibonelela ngokulula nangokusebenzisa imali kakuhle, zinokuba nemida ngokwembono ephakathi kunye nomgca obonakalayo phakathi kwamacandelo. Kucetyiswa rhoqo ukuba udibane nogqirha wamehlo okanye ingcali yokhathalelo lwamehlo ukuze ufumane ukhetho lwelensi olufanelekileyo ngokusekelwe kwiimfuno zomntu ngamnye kunye nezinto azikhethayo.
