I-lenses ye-Bifocal i-lenses ekhethekileyo yamehlo eyenzelwe ukuhlangabezana neemfuno ezibonakalayo zabantu abanobunzima bokugxila kwizinto ezikufutshane nezikude. Ezi zinto zilandelayo zizinto eziphambili ekufuneka ziqwalaselwe xa zixoxa ngokusetyenziswa kweelensi ze-biifocal:
Ukulungiswa kwePresbypia:Iilensi ze-Bifocal Iilensi zisetyenziselwa ukulungisa iPrestogoopia, imposiso enxulumene nobudala echaphazela amandla esweni lokugxila kwizinto ezikufutshane. Imeko ihlala ivela kwiminyaka engama-40 kwaye ibangela ukuba ukufunda, ukusebenzisa izixhobo zedijithali kunye nokwenza eminye imisebenzi esondeleyo.
Ukulungiswa kombono kabini:Iilensi ze-Bifocal Iilensi zinamagunya amabini ahlukeneyo kwilensi enye. Inxalenye ephezulu yelensi iyilelwe ngokukodwa ukulungisa umbono womgama, ngelixa inxalenye engezantsi iqulethe i-diopter eyongezelelweyo kumbono okufutshane. Le ndlu i-sued ivumela abaguli basePorboondic ukuba babe neqhosha leglasi ukuze bahlangabezane neemfuno zabo kwimigama eyahlukeneyo.
Inguqu engenamthungo:Uyilo lweelensi ze-biifocal lwe-biifocal luvumela utshintsho olungenamthungo phakathi kwecandelo elingaphezulu nezantsi kwelensi. Olu tshintsho lugudileyo lubaluleke kakhulu kumava asemgangathweni afanelekileyo kwaye afanelekileyo xa etshintshela phakathi kwemisebenzi efuna umbono osondeleyo kunye nombono womgama.
Ukusebenza ngokulula:Iilensi ze-Bifocal zibonelela ngokulula kunye nokuxabiseka kwabantu abane-Pressopia ngokubonelela ngesisombululo sombono osondeleyo kunye nomgama omnye kwisibini seglasi. Endaweni yokuhlala rhoqo phakathi kwezimbini ezininzi zeglasi, abasebenzisi banokuxhomekeka kwiibhombu zemisebenzi kunye nemisebenzi, njengokufunda, ukuqhuba, umsebenzi wekhompyuter, kunye nombono wekhompyuter.
Ukusetyenziswa emsebenzini:Iilensi ze-Biifocal zilungele abantu abasebenzela imisebenzi okanye imisebenzi yemihla ngemihla efuna utshintsho olwenzeka rhoqo phakathi kwekufuphi nenqanaba. Oku kubandakanya imisebenzi efana nabanikezeli bezempilo, ootitshala, oomatshini, kunye namagcisa, apho umbono ocacileyo we-AID kumgama ohlukeneyo ubalulekile ekusebenzeni kakuhle nasekukhuseleni.
Ukwenza ngokwezifiso zemfundo nganye: Iilensi ze-bifucal zinokwenziwa ukufezekisa iimfuno ezithile zomntu ngamnye. I-Optometrists kunye ne-Ophthalmologists ivavanya ngenyameko iimfuno ezibonakalayo zesigulana kunye nendlela yokuphila yokumisela eyona uyilo luyilo lwe-BifoCal Lensi, ukuqinisekisa ukuba amayeza ahlangabezana neemfuno zomsebenzi wabo wokuzonwabisa kunye nemisebenzi yokuzonwabisa.
Ngokuthe ngcembe ukuziqhelanisa:Kwiilensi ezintsha ze-bobocal Lensi, kukho ixesha lohlengahlengiso lwamehlo ukuhlengahlengisa kwiilensi ze-biigocal. Izigulana zinokufumana imiceli mngeni yokuhlengahlengiswa kwiindawo ezigxile kuzo kwiilensi, kodwa zinexesha kwaye ziqhelisela, uninzi lwabantu luyekisa kakuhle kwaye lunandiphe izibonelelo zombono ophuculweyo nombono womgama.
Ukuqukumbela, iilensi ze-biifocal zibalulekile ukujongana nemicelimingeni eyahlukileyo yombono eboniswe nguPresbyOpia. Uyilo lwazo lweDude-phengulu, inguqu engenamthungo, lula, ukuba kube lula, kunye nokuzizuza, kunye nokwenza ngokwezifiso zibenze umbono wabantu ofuna umgama ocacileyo kubomi babo bemihla ngemihla.
Ngubani ekufuneka enxibe ii-bifoci?
Iiglasi ze-Bifocal zihlala zimiselwa abantu abanoPersbyOpia, imeko enxulumene nobudala echaphazela amandla eliso kugxile kwizinto ezikufuphi ne-Elasticity kwilensi yendalo. I-Persgoopia ihlala ibonakala kubantu abangaphezu kweminyaka engama-40, bubangela ubunzima bokufunda, ukusebenzisa izixhobo zedijithali, kunye nokwenza eminye imisebenzi ekufutshane. Ukongeza kwi-Persogoopia enxulumene nobudala, iiglasi ze-bifucal zinokucetyiswa kubantu abajamelana nomsebenzi kunye nezomngeni zobuhlobo ngenxa yezinye iimpazamo ezingxamisekileyo ezifana noxinzelelo okanye i-myopia. Ke ngoko, iiglasi zebhayila zibonelela ngesisombululo esifanelekileyo sabantu abafuna amandla awahlukeneyo okuhlangabezana neemfuno zabo kwimigama eyahlukeneyo.
Ufanele unxibe nini ii-bifocals?
Iiglasi ze-Bifocal zihlala zicetyiswa kubantu abanobunzima bokubona izinto ezisondeleyo ngenxa yePressopia, inkqubo yokwaluphala echaphazela izinto ezikufutshane. Imeko ihlala ivela kwiminyaka engama-40 kwaye iba mandundu ekuhambeni kwexesha. I-Pressopia inokubangela iimpawu ezinje ngecala leliso, imbonakalo yentloko, umbono ophathwayo kunye nobunzima bokufunda kancinci. Iiglasi ze-Bifocal zinokubanceda nakwabantu abanezinye iimpazamo ezihlaziyiweyo, ezinjengokungathandekiyo okanye ukubaluleka, kwaye ngubani ofuna amagunya ahlukeneyo okukufutshane kunye nombono womgama. Ukuba ufumanisa ukuba uhlala ungafundanga ukusuka ekufundeni izinto zokufunda, amava amehlo xa ufunda okanye esebenzisa izixhobo zedijithali, kunokuba lixesha lokuqwalasela ii-bifoci. Ukongeza, ukuba sele unxibe iiglasi zombono womgama kodwa ufumana ubunzima ngemisebenzi esecaleni, ii-biifocals zinokubonelela ngesisombululo esifanelekileyo. Ekugqibeleni, ukuba unengxaki ejongene nombono okanye ufumanise ukuba kunzima ukutshintshela phakathi kwezimbini zeglasi kwimisebenzi eyahlukileyo, ukuxoxa nge-bifuculals onokukhathalela i-gocing onokukhathalela ukuba ngaba ufuna uncedo.
Nguwuphi umahluko phakathi kweebhasi kunye neelensi rhoqo?
Ii-bifocals kunye neelensi rhoqo zombini iintlobo zeelebhu zamehlo ezisebenza ngeenjongo zamehlo kwaye zihlangabezane neemfuno ezahlukeneyo zobumvo. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeelensi kunokunceda abantu benze izigqibo ezinolwazi malunga nokukhetha ukulungiswa kombono.
Iilensi eziqhelekileyo: Iilensi rhoqo, zikwabizwa ngokuba ziilensi zombono, zenzelwe ukulungisa impazamo ethile ecacileyo, enjengokusondela, ukubaluleka, okanye i-atigmatism. Ezi lelses zinamagunya angaguqukiyo ngonyango kuwo wonke umhlaba kwaye zihlala zenzelwe ukubonelela ngombono ocacileyo kumgama omnye, nokuba kufutshane, umbono ophakathi, okanye umbono ophakathi. Abantu abanoncedo olunokuthi bangenelwe kuzo kwiilensi zomculo ezibavumela ukuba babone izinto ezikude ngokucacileyo, ngelixa abantu abangenaleyo banokufuna ukuphucula umbono wabo kufutshane. Ukongeza, abantu abane-astigmatism bafuna i-lenses yokuhlawula i-curvature engaqhelekanga ye-cornea okanye i-lens yeliso, ebavumela ukuba bajolise ngokuchanekileyo kwi-retina.
I-Bifocal Lenses: Iilensi ze-Bifocal zahlukile kuba zinamagunya amabini awahlukeneyo ngaphakathi kwilensi efanayo. Iilensi zenzelwe ukujongana ne-Persogoopia, imeko enxulumene nobudala echaphazela amandla esweni lokugxila kwizinto ezikufutshane. Njengoko sineminyaka esidala, iilensi zemvelo zeliso ziba bhetyebhetye, zenza ukuba kube nzima ukugxila kwimisebenzi ekufutshane nokufunda, ukusebenzisa umsebenzi we-smartphone, okanye ukwenza umsebenzi oneenkcukacha. Uyilo lweelensi ze-biifocal lubandakanya umgca obonakalayo ohlulahlula iinxalenye eziphezulu nangaphantsi zelensi. Inxalenye ephezulu yelensi isetyenziselwa umbono womgama, ngelixa isahlulo esisezantsi liqulathe amandla ahlukileyo kumbono osondeleyo kumbono. Lo uyilo lwamanzi olubini luvumela abaqhubi ukuze babone ngokucacileyo kumgama owahlukileyo ngaphandle kokutshintsha phakathi kwezimbini ezininzi zeeglasi. Izicombululo ze-Bifocal zibonelela ngesisombululo esifanelekileyo nesiguquguqukayo kubantu abafuna umbono wokulungiswa kwemisebenzi esecaleni nakwindawo.
Umahluko ophambili: Umahluko ophambili phakathi kweelensi ze-biibical kunye neelensi rhoqo kuyilo kunye nokusetyenziswa kwenjongo. I-lense eqhelekileyo ijongana neempazamo ezithile zokwenza umonakaze kwaye zinike umbono ocacileyo kwindawo enye, ngelixa iilensi ze-bifuccal ziyilelwe ngokukodwa ukuhlalisa iPressopia kwaye zibonelela ngokulungiswa kwe-biphoto kumbono okufutshane kunye nombono womgama. I-lensed rhoqo isetyenziselwa ukulungisa ukungakhathali, ukungabi naluthando, kunye nokungcungcutheka, ngelixa iilensi zebhafini zibonelela ngombono ocacileyo wokudibanisa amagunya amabini amiselweyo kwilensi emibini. Isishwankathelo, i-lenses eqhelekileyo ye-lense kwimpazamo ethile yokuphinda inyange kwaye inike ukulungiswa kombono omnye, ngelixa iilensi ze-bifucal zenzelwe ukulungisa i-Persgoopia kwaye zibonelela ngesisombululo se-biifocal se-biifocal sisondele kwaye sinembono yomgama we-biifocal. Ukuqonda umahluko phakathi kwezi ntlobo zimbini zeelensi kunokunceda abantu bakhetha eyona ndlela ifanelekileyo yokulungisa umbono osekwe kwiimfuno zabo zobuqu kunye nezinto ozithandayo.
