Ama-lens we-bifocal akhethekile ama-eyeglass lens aklanyelwe ukufeza izidingo ezibukwayo zabantu abanobunzima bokugxila ezintweni eziseduzane nasekude. Okulandelayo amaphuzu asemqoka okufanele ucatshangelwe lapho uxoxa ngokusetshenziswa kwamalensi we-bifocal:
Ukulungiswa kwe-Presbyopia:Ama-lens we-biforal asetshenziselwa ukukulungisa ama-presbyopia, iphutha elihlobene nobudala elithinta ikhono lamehlo okugxila ezintweni eziseduze. Isimo sivame ukuvela cishe iminyaka engama-40 futhi sibangela ukufundwa kobunzima, kusetshenziswa amadivaysi edijithali nokwenza eminye imisebenzi esondelene.
Ukulungiswa kombono okuphindwe kabili:Amalensi we-biforal anamandla amabili ahlukile ahlukile elensi eyodwa. Ingxenye engenhla ye-lens yenzelwe ngqo ukulungisa amabanga, ngenkathi ingxenye engezansi iqukethe i-diopter eyengeziwe yombono oseduze. Lo mbhalo ombaxambili uvumela iziguli ze-Presbyopic ukuba zibe nezibuko ezimbili ukuze zihlangabezane nezidingo zabo zombono kumabanga ahlukene.
Ukuguqulwa komthungo:Idizayini yamalensi we-bifocal ivumela ukuguqulwa komthungo phakathi kwezingxenye ezingenhla nezingaphansi zelensi. Lokhu kuguqulwa okubushelelezi kubalulekile kulwazi lokubuka olunethezekile nolusebenzayo lapho ushintsha phakathi kwemisebenzi edinga ukubonwa kwebanga nebanga.
Ukusebenziseka Kanye nokuguquguqukayo:Amalensi we-Bifocal ahlinzeka ngokulula nokuguquguquka kubantu abane-Presbyopia ngokuhlinzeka ngesisombululo sombono oseduze nokwengezamba ebholeni elilodwa lezibuko. Esikhundleni sokushintsha njalo phakathi kwamabili ama-balting of izibuko, abasebenzisi bangathembela kuma-bifoocals ngemisebenzi nemisebenzi ehlukahlukene, njengokufunda, ukushayela, umsebenzi wekhompyutha, kanye nokuzilibazisa okubandakanya eduze noma umbono wobude.
Ukusetshenziswa Kwemisebenzi:Ama-lens we-biforal ngokuvamile alungele abantu abasebenza kuyo noma imisebenzi yansuku zonke edinga izinguquko ezivame kakhulu phakathi nebanga. Lokhu kufaka phakathi imisebenzi efana nabahlinzeki bezokunakekelwa kwempilo, othisha, ama-mechanics, kanye nabadwebi, lapho umbono ocacile kumabanga ahlukahlukene ubucayi ukusebenza kahle nokuphepha.
Ukwenza ngokwezifiso izidingo ngazinye: Ama-lens we-biforal angahle abekwe ngokwezifiso ukufeza izidingo ezithile ezithile. Ama-Optometrists kanye nodokotela we-ophthalmologists bahlola ngokucophelela izidingo ezibukwayo zesiguli kanye nendlela yokuphila ukuze banqume ukwakhiwa okufanele kakhulu kwe-bifocal lens, ukuqinisekisa ukuthi umuthi uhlangabezana nezidingo zomsebenzi wabo kanye nokuzilibazisa.
Kancane kancane ajwayele:Kwabagqoke ama-lens amasha we-bifocal, kunesikhathi sokulungiswa kwamehlo ukujwayela ama-biforal lens. Iziguli ekuqaleni zingathola izinselelo ezivumelana namaphoyinti ahlukene okugxila ngaphakathi kwelensi, kepha ngokuhamba kwesikhathi nangokuzijwayeza, iningi labantu, abantu abaningi bavumelana kahle futhi bajabulele izinzuzo zombono othuthukisiwe kanye nokwenza amabanga.
Ekuphetheni, amalensi we-biforal abalulekile ukubhekana nezinselelo ezihlukile zombono ezethulwe yi-Presbyopia. Idizayini yabo yemibhalo ebanjwayo, ukuguquka komthungo, ukusebenziseka kalula, ukuguquguquka, kanye nokwenza ngokwezifiso okungenzeka kubenze kube yisisombululo esifanelekile sabantu abafuna amabanga ahlukahlukene ezimpilweni zabo zansuku zonke.
Ngubani odinga ukugqoka ama-bifocals?
Izibuko ze-BIFOCAL zivame ukubekelwa abantu abane-Presbyopia, isimo esihlobene nobudala esithinta amandla eso okugxila ezintweni eziseduzane ngenxa yokulahleka kwemvelo kwe-lens yeso. I-Presbyopia imvamisa iba valant kubantu abaneminyaka engaphezu kwengu-40, ibangele ukufundwa kobunzima, ukusebenzisa amadivaysi edijithali, nokwenza eminye imisebenzi eseduze. Ngaphezu kwe-presbybybybybybybylopia ehlobene nobudala, izibuko ze-biforal nazo zinganconyelwa kubantu ababhekene nezinselelo zezinselelo zezinselelo ngenxa yamanye amaphutha avumayo afana nokubuka kude noma i-myopia. Ngakho-ke, izibuko ze-biforal zinikezela ngesisombululo esikahle sabantu abadinga amandla ahlukile okubona ahlangabezana nezidingo zabo zombono kumabanga ahlukene.
Kufanele ugqoke nini ama-bifocals?
Izibuko ze-BIFOCAL zivame ukunconyelwa kubantu abanobunzima bokubona izinto ezisondele ngenxa ye-Presbyopia, inqubo yokuguga yemvelo ethinta ikhono lamehlo okugxila ezintweni eziseduzane. Isimo sivame ukuvela cishe iminyaka engama-40 futhi sibi kakhulu ngokuhamba kwesikhathi. I-Presbyopia ingadala izimpawu ezinjengobunzima bamehlo, ikhanda, umbono ofiphele nobunzima bokufunda ukuphrinta okuncane. Izibuko ze-BIFOCAL nazo zingasiza abantu abanamanye amaphutha avumileyo, njengokuthi aseduze noma ekubini kokubi, futhi abadinga amandla ahlukahlukene okugunyazwa kombono webanga eliseduze nokwengeziwe. Uma uthola ukuthi uvame ukuba kude nokufunda okufundwayo, uhlangabezana nobunzima bamehlo lapho ufunda noma usebenzisa amadivaysi edijithali, noma kudingeka ukhiphe izibuko zakho ukuze ubone izinto ezisondelene. Ngokwengeziwe, uma usuvele ugqoke izingilazi zokubuka amabanga kodwa uzithola unenkinga ngemisebenzi eseduze, ama-bifocals anganikeza isixazululo esikahle. Ekugcineni, uma unenkinga ngombono oseduze noma ukuthole kunzima ukushintsha phakathi kwamabili amabhangqa amaningi emisebenzi ehlukene, ukuxoxa ngama-bifocals ngochwepheshe wokunakekelwa kwamehlo kungasiza ekuboneni ukuthi ziyindlela efanelekile yezidingo zakho zombono.
Uyini umehluko phakathi kwama-bifocals namalensi ajwayelekile?
Ama-bifocals nama-lens ajwayelekile zombili izinhlobo ze-eyeglass lens ezisebenzela izinhloso ezihlukile futhi zihlangabezane nezidingo ezihlukile zombono. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-lens kungasiza abantu abathile benze izinqumo ezinolwazi mayelana nezinketho zokulungiswa kombono.
Ama-lens ajwayelekile: ama-lens ajwayelekile, abizwa nangokuthi ama-lens elilodwa lombono, aklanyelwe ukulungisa iphutha elithile lokuphinda avuselelayo, njengokubuka okuseduze, ekubuseni, noma i-astigmatism. Lawa ma-lens anamandla anikezwayo ahambisane nawo wonke umuntu wawo wonke umuntu futhi ngokujwayelekile yakhelwe ukuhlinzeka ngombono ocacile ebanga elilodwa, kungaba eduze, noma ngabe ubonakale. Abantu abaseduze bangazuza kumalensi abekiwe avumela ukuthi abone izinto ezikude ngokucacile, kanti abantu abakude bangadinga amalensi ukuthuthukisa umbono wabo oseduze. Ngaphezu kwalokho, abantu abane-astigmatism badinga ama-lens ukunxephezela i-curvature engajwayelekile ye-cornea noma ilensi yamehlo, ebavumela ukuba bagxile ngokulula ku-retina.
Ama-lens we-bifocal: amalensi we-biforal ahlukile kulokho aqukethe amandla amabili ahlukene ahlukile ngaphakathi kwelensi efanayo. Ama-lens aklanyelwe ukubhekana nama-presbyopia, isimo esihlobene nobudala esithinta amandla eso okugxila ezintweni eziseduze. Njengoba sikhula, ilensi yemvelo yeso iba kancane iguquguqukayo, okwenza kube yinselele ukugxila emisebenzini eseduze njengokufunda, ukusebenzisa i-smartphone, noma ukwenza umsebenzi onemininingwane. Idizayini yama-biforal lens ifaka umugqa obonakalayo ohlukanisa izingxenye ezingenhla nezingaphansi zelensi. Ingxenye engenhla yelensi ngokuvamile isetshenziselwa ukubuka kwebanga, ngenkathi ingxenye engezansi iqukethe amandla ahlukile asusa avumayo wombono oseduze. Le design enamandla ama-Dual-Power ivumela abagqoke ukubona kahle kumabanga ahlukene ngaphandle kokushintsha phakathi kwamabili ama-balting. Amalensi we-Bifocal anikezela ngesisombululo esikahle futhi esiguquguqukayo sabantu abadinga ukulungiswa kombono kwemisebenzi yebanga eliseduze nebanga.
Umehluko omkhulu: Umehluko omkhulu phakathi kwamalensi we-bifocal nama-lens ajwayelekile ukwakheka kwawo nokusetshenziswa okuhlosiwe. Ama-lens ajwayelekile abhekana namaphutha athile aphindaphindwayo futhi anikeze umbono ocacile ebanga elilodwa, ngenkathi ama-lens we-biforal aklanyelwe ngokukhethekile ukwamukela ama-presbybyopia futhi anikeze ukulungiswa kwe-bipoto eduze nombono we-bipoto. Ama-lens ajwayelekile asetshenziselwa ukulungisa ubungako besikhathi esiseduze, ekubiseni, kanti ama-astigmatism, ngenkathi amalensi e-biforal ahlinzeka ngombono ocacile kumabanga amaningi ngokuhlanganisa amandla amabili kadokotela kwilensi efanayo. Ngamafuphi, amalensi ajwayelekile abheke ngephutha elithile lokuphinda aphinde anikeze ukulungiswa okukodwa, kanti ama-lens we-biforal aklanyelwe ukubhekana nama-presbyopia futhi anikeze isixazululo se-bIforal sombono oseduze nokwengezamba. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zama-lens kungasiza abantu ukuthi bakhethe inketho efanelekile yokulungisa umbono ngokususelwa ezidingweni zabo kanye nezinketho zabo.
