Ikwiposti yebhlog yanamhlanje, siza kuphonononga ingqikelelo yeelensi ze-bifocal ezimcaba, ukufaneleka kwazo kubantu abohlukeneyo, kunye nezinto eziluncedo nezingeloncedo abazinikezelayo. Iilensi ze-bifocal ezithe tyaba zilukhetho oludumileyo lwabantu abafuna ukulungiswa kombono okufutshane kunye nomgama kwiperi enye yeeglasi.
Isishwankathelo seeLensi zeBifocal eziPhakamileyo:
Iilensi ze-Flat top bifocal luhlobo lwe-lens ye-multifocal edibanisa izilungiso ezimbini zombono kwilensi enye. Ziquka inxalenye engaphezulu ecacileyo yombono womgama kunye necandelo elisicaba elichaziweyo kufuphi nomzantsi ukuze ubone umbono okufutshane. Olu luyilo luvumela abasebenzisi ukuba babe notshintsho olungenamthungo phakathi kobude obugqalileyo obahlukeneyo ngaphandle kwemfuneko yeeperisi ezininzi zeeglasi.
Ukufaneleka kwabantu abohlukeneyo:
Iilensi ze-bifocal ezimcaba zifaneleke kakuhle kubantu abafumana i-presbyopia, ubunzima bendalo obunxulumene nobudala bokugxila kwizinto ezisondeleyo. I-Presbyopia ichaphazela abantu abangaphezu kweminyaka engama-40 kwaye inokubangela ukuxinezeleka kwamehlo kunye nokubona luzizi. Ngokudibanisa zombini izilungiso zombono okufutshane kunye nomgama, iilensi ze-bifocal ezisicaba zibonelela ngesisombululo esisebenzayo kwaba bantu, ukuphelisa ingxaki yokutshintsha phakathi kweeperi ezahlukeneyo zeglasi.
Izinto eziluncedo kwiiLensi zeFlathi eziPhezulu zeBifocal:
Uncedo: Ngeelensi ze-bifocal ezithe tyaba eziphezulu, abanxibi banokonwabela ukubona izinto ezikufuphi nezikude ngokucacileyo ngaphandle kokutshintsha iindondo. Oku kunenzuzo ngakumbi kwabo batshintsha rhoqo phakathi kwemisebenzi efuna amanqanaba ahlukeneyo okubonwayo.
Ukonga imali: Ngokudibanisa ukusebenza kweelensi ezimbini zibe nye, iilensi ezimcaba ezithe tyaba ezingaphezulu ziphelisa imfuneko yokuthenga iiperisi ezahlukeneyo zeeglasi zokubona kufuphi nakumgama. Oku kubenza babe lukhetho olungabizi kakhulu kubantu abane-presbyopia.
Ukuziqhelanisa: Xa sele beziqhelile iilensi ze-bifocal ezithe tyaba eziphezulu, abasebenzisi bazifumana bekhululekile kwaye kulula ukuziqhelanisa nazo. Utshintsho phakathi komgama kunye namacandelo ombono okufutshane alunamthungo ngokuhamba kwexesha.
Izinto ezingeloncedo kwiiLensi zeFlat eziPhezulu zeBifocal:
Umbono ophakathi olinganiselweyo: Njengoko iilensi ze-bifocal ezisicaba zijolise ikakhulu kumbono okufutshane kunye nomgama, indawo yombono ophakathi (efana nokujonga isikrini sekhompyuter) inokungacaci kangako. Abantu abafuna umbono obukhali ophakathi banokufuna ukuqwalasela ezinye iindlela zokukhetha iilensi.
Umgca obonakalayo: Iilensi ze-Flat ze-bifocal zinomgca obonakalayo ocacileyo owahlula umgama kunye namacandelo akufutshane. Nangona lo mgca ungabonakali kakuhle kwabanye, abanye abantu banokukhetha inkangeleko engenamthungo ngakumbi, bethathela ingqalelo enye indlela yoyilo lwelensi efana neelensi eziqhubekayo.
Iilensi ze-bifocal ezimcaba zibonelela ngesisombululo esisebenzayo kubantu abane-presbyopia, ebonelela ngombono ocacileyo wazo zombini izinto ezikufutshane kunye nezikude kwipere enye yeglasi. Ngelixa banikezela ngokulula kunye nokusebenza kakuhle, banokuba nemida ngokwembono ephakathi kunye nomgca obonakalayo phakathi kwamacandelo. Kuhlala kucetyiswa ukuba udibane nogqirha wamehlo okanye ingcali yokunakekelwa kwamehlo ukumisela eyona ndlela ifanelekileyo yelensi esekelwe kwiimfuno zomntu ngamnye kunye nezinto ezikhethwayo.
