Asetshenziselwani ama-bifocal lens?

Amalensi e-Bifocal amalensi engilazi yamehlo akhethekile aklanyelwe ukuhlangabezana nezidingo zokubukwa kwabantu abanobunzima bokugxila ezintweni eziseduze nezikude.Okulandelayo amaphuzu abalulekile okufanele acatshangelwe lapho kuxoxwa ngokusetshenziswa kwamalensi e-bifocal:
Ukulungiswa kwe-Presbyopia:Amalensi e-Bifocal asetshenziswa ngokuyinhloko ukuze kulungiswe i-presbyopia, iphutha le-refractive elihlobene neminyaka elithinta ikhono leso lokugxila ezintweni eziseduze.Lesi simo sivame ukuvela cishe eminyakeni engu-40 futhi kubangela ubunzima bokufunda, ukusebenzisa amadivaysi edijithali nokwenza eminye imisebenzi eseduze.
Ukulungiswa kokubona kabili:Amalensi e-Bifocal anamandla amabili ahlukene okubona kulensi eyodwa.Ingxenye engenhla yelensi iklanyelwe ngokuqondile ukulungisa indlela yokubona ebangeni, kuyilapho ingxenye engezansi iqukethe i-diopter eyengeziwe yokubona eduze.Le mithi kadokotela ekabili ivumela iziguli ze-presbyopic ukuthi zibe nepheya lezibuko ukuze zihlangabezane nezidingo zazo zokubona emabangeni ahlukene.
Inguquko engenazihibe:Idizayini yamalensi e-bifocal ivumela uguquko olungenamthungo phakathi kwezingxenye ezingaphezulu neziphansi zamalensi.Lolu shintsho olubushelelezi lubalulekile ekuzizwiseni okunethezekile nokusebenza kahle uma ushintsha phakathi kwemisebenzi edinga ukubona eduze nebanga.
Ukusebenziseka kalula nokuhlukahluka:Amalensi e-Bifocal ahlinzeka ngokunethezeka nokuguquguquka kubantu abane-presbyopia ngokunikeza isixazululo sokubona eduze nebanga kupheya eyodwa yezibuko.Esikhundleni sokuhlala beshintshana phakathi kwamapheya amaningi ezingilazi, abasebenzisi bangathembela kuma-bifocal ukuze benze imisebenzi ehlukahlukene nemisebenzi, njengokufunda, ukushayela, umsebenzi wekhompuyutha, nokuzilibazisa okubandakanya ukubona eduze noma ibanga.
Ukusetshenziswa emsebenzini:Amalensi e-Bifocal ngokuvamile afanele abantu imisebenzi yabo noma imisebenzi yansuku zonke edinga ushintsho oluvamile phakathi kwebanga eliseduze nebanga.Lokhu kufaka phakathi imisebenzi efana nabahlinzeki bezempilo, othisha, umakhenikha, namaciko, lapho umbono ocacile emabangeni ahlukahlukene ubalulekile ekusebenzeni okuhle nokuphepha.
Ukwenza ngokwezifiso izidingo zomuntu ngamunye: Amalensi e-Bifocal angenziwa ngendlela oyifisayo ukuze ahlangabezane nezidingo eziqondile zomuntu ngamunye.Odokotela bamehlo nodokotela bamehlo bahlola ngokucophelela izidingo ezibukwayo zesiguli nendlela yokuphila ukuze banqume idizayini yelensi ye-bifocal efaneleke kakhulu, baqinisekise ukuthi incwadi kadokotela ihlangabezana nezidingo zomsebenzi wabo nezokungcebeleka.
Kancane kancane zijwayela ku:Kubantu abasha abagqoka ilensi ye-bifocal, kunesikhathi sokulungisa ukuze amehlo ajwayele amalensi e-bifocal.Iziguli ekuqaleni zingase zibe nezinselele zokulungisa izindawo okugxilwe kuzo ezihlukene ngaphakathi kwelensi, kodwa ngokuhamba kwesikhathi nokuzijwayeza, abantu abaningi bazijwayeza kahle futhi bajabulele izinzuzo zokubona okuthuthukisiwe okuseduze nebanga.

okuqhubekayo-noma-bifocal
Sengiphetha, amalensi e-bifocal abalulekile ukubhekana nezinselele zombono eziyingqayizivele ezethulwa i-presbyopia.Idizayini yabo yemithi ekabili, uguquko olungenamthungo, ukuba lula, ukuguquguquka, namandla okwenza ngokwezifiso abenza babe yisixazululo esikahle sabantu abafuna ukubona okucacile nokunethezekile emabangeni ahlukahlukene empilweni yabo yansuku zonke.

Ubani okufanele agqoke ama-bifocals?

Izibuko ze-Bifocal ngokuvamile zimiselwe abantu abane-presbyopia, isimo esihlobene neminyaka esithinta ikhono leso lokugxila ezintweni eziseduze ngenxa yokulahlekelwa okungokwemvelo kokunwebeka kwelensi yeso.I-Presbyopia ivamise ukubonakala kubantu abangaphezu kweminyaka yobudala engama-40, okubangela ubunzima bokufunda, ukusebenzisa amadivaysi edijithali, nokwenza eminye imisebenzi eseduze.Ngokungeziwe ku-presbyopia ehlobene neminyaka, izibuko ze-bifocal zingase futhi zinconywe kubantu ababhekene nezinselele zebanga neziseduze zokubona ngenxa yamanye amaphutha aphikisayo afana nokubona kude noma i-myopia.Ngakho-ke, izibuko ze-bifocal zinikeza isixazululo esikahle kubantu ngabanye abadinga amandla ahlukene okubona ukuze bahlangabezane nezidingo zabo zokubona ezindaweni ezihlukene.

Kufanele ugqoke nini ama-bifocal?

Izibuko ze-Bifocal zivame ukutuswa kubantu abanobunzima bokubona izinto eziseduze ngenxa ye-presbyopia, inqubo yokuguga yemvelo ethinta ikhono lamehlo lokugxila ezintweni eziseduze.Lesi simo ngokuvamile sivela eminyakeni engama-40 futhi siba sibi ngokuhamba kwesikhathi.I-Presbyopia ingabangela izimpawu ezinjengokucindezelwa kwamehlo, ikhanda elibuhlungu, ukungaboni kahle kanye nobunzima bokufunda imibhalo emincane.Izibuko ze-Bifocal zingaphinda zizuze abantu abanamanye amaphutha e-refreact, afana nokubona eduze noma ukubona kude, futhi abadinga amandla ahlukene okuphendula ukuze babone eduze nakude.Uma uthola ukuthi uvamise ukuqhelelene nezinto zokufunda, uhlangabezana nokuxineka kwamehlo lapho ufunda noma usebenzisa amadivaysi edijithali, noma udinga ukususa izibuko zakho ukuze ubone izinto eduze, kungase kube isikhathi sokucabangela ama-bifocal.Ukwengeza, uma usuvele ugqoke izibuko ukuze ubone ibanga kodwa uzithole unobunzima ngemisebenzi eseduze, ama-bifocal angakunikeza isisombululo esikahle.Ekugcineni, uma unenkinga yokubona eduze noma ukuthola kunzima ukushintsha phakathi kwamapheya amaningi ezibuko ukuze wenze imisebenzi ehlukene, ukuxoxa nge-bifocal nochwepheshe wokunakekelwa kwamehlo kungasiza ekunqumeni ukuthi ayisinqumo esifanele yini sezidingo zakho zombono.

Uyini umehluko phakathi kwama-bifocals namalensi avamile?

Ama-Bifocals namalensi avamile yizo zombili izinhlobo zamalensi engilazi yamehlo asebenza ngezinjongo ezihlukene futhi ahlangabezana nezidingo ezihlukene zokubona.Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamalensi kungasiza abantu ukuthi benze izinqumo ezinolwazi mayelana nezinketho zokulungisa umbono.
Amalensi avamile: Amalensi avamile, aphinde abizwe ngokuthi ama-single vision lens, aklanyelwe ukulungisa iphutha elithile lokuphendula, elifana nokubona eduze, ukubona kude, noma i-astigmatism.Lawa ma-lens anamandla anikezwe udokotela angashintshi endaweni yawo yonke futhi aklanyelwe ukunikeza umbono ocacile ebangeni elilodwa, kungakhathaliseki ukuthi liseduze, elimaphakathi, noma lebanga.Abantu ababona eduze bangazuza kumalensi kadokotela abavumela ukuba babone izinto ezikude ngokucacile, kuyilapho abantu ababona kude bangase badinge amalensi ukuze bathuthukise ukubona kwabo eduze.Ngaphezu kwalokho, abantu abane-astigmatism badinga amalensi ukuze banxephezele ukugoba okungajwayelekile kwe-cornea noma ilensi yamehlo, okubavumela ukuthi bagxilise ukukhanya ngendlela efanele ku-retina.
Amalensi e-Bifocal: Amalensi e-Bifocal ahlukile ngoba aqukethe amandla amabili ahlukene okubona ngaphakathi kwelensi efanayo.Amalensi aklanyelwe ukubhekana ne-presbyopia, isimo esihlobene neminyaka esithinta ikhono leso lokugxila ezintweni eziseduze.Njengoba sikhula, ilensi yemvelo yeso iyancipha ukuguquguquka, okwenza kube inselele ukugxila emisebenzini eseduze njengokufunda, ukusebenzisa i-smartphone, noma ukwenza umsebenzi onemininingwane.Idizayini yamalensi e-bifocal ihlanganisa umugqa obonakalayo ohlukanisa izingxenye ezingenhla nezingezansi zelensi.Ingxenye engenhla yelensi ivamise ukusetshenziselwa ukubona kude, kuyilapho ingxenye engezansi iqukethe amandla ahlukene acwebezelayo okubona eduze.Lo mklamo wamandla amabili uvumela abagqokile ukuthi babone ngokucacile emabangeni ahlukene ngaphandle kokuthi bashintshe phakathi kwamapheya amaningi ezingilazi.Amalensi e-Bifocal ahlinzeka ngesixazululo esilula nesiguquguqukayo sabantu ngabanye abadinga ukulungiswa kokubona kukho kokubili imisebenzi eseduze nebanga.
Umehluko omkhulu: Umehluko omkhulu phakathi kwamalensi e-bifocal namalensi avamile ukwakheka kwawo kanye nokusetshenziswa okuhlosiwe.Amalensi avamile akhuluma ngamaphutha athile avela ku-refractive futhi anikeze ukubona okucacile ebangeni elilodwa, kuyilapho amalensi e-bifocal eklanyelwe ngokukhethekile ukuthwala i-presbyopia futhi anikeze ukulungiswa kwe-biphoto ukuze ubone eduze nebanga.Amalensi avamile asetshenziselwa ukulungisa ukubona eduze, ukubona kude, ne-astigmatism, kuyilapho amalensi e-bifocal enikeza ukubona okucacile emabangeni amaningi ngokuhlanganisa amandla amabili kadokotela kulensi efanayo.Kafushane, amalensi avamile abhekelela iphutha elithile le-refractive futhi anikeze ukulungiswa kombono owodwa, kuyilapho amalensi e-bifocal eklanyelwe ukubhekana ne-presbyopia futhi anikeze isixazululo se-bifocal sokubona eduze nebanga.Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili zamalensi kungasiza abantu ukuba bakhethe inketho efanelekile yokulungisa umbono ngokusekelwe ezidingweni zabo siqu kanye nalokho abakuthandayo.
