Sifaka imikhiqizo esicabanga ukuthi abafundi bethu bazoyithola iwusizo.Singase sizuze ikhomishini encane uma uthenga ngesixhumanisi esikuleli khasi.Lena inqubo yethu.
Uma ubulokhu unombono ongu-20/20 impilo yakho yonke noma ugqoke amalensi okulungisa iminyaka, ungase udinge ama-bifocals ngesinye isikhathi.
Qhubeka ufunde ukuze ufunde kabanzi mayelana nokuthi ungawadinga nini noma ungawadingi nini amalensi othintana naye we-bifocal futhi uhlole ukukhetha kwethu kwamalensi okuxhumana angcono kakhulu e-bifocal.
Ungase ukwazi!Abantu abaningi bayayijabulela inkululeko abayinikwa yi-bifocal contact lens futhi bathole ukuthi bangawagqoka ngempumelelo.
Amalensi Okuxhumana Anemibala Anamandla
Uma ungakaze ugqoke ama-contact lens ngaphambilini, uzodinga ukufunda ukuwafaka nokuwagqoka.
Uzoba nejika lokufunda futhi ngenxa yokuthi ane-multifocal, okusho ukuthi anezindawo ezintathu okugxilwe kuzo ezihlukene: eyokubona kude, enye eyokubona okuphakathi, neyokubona eduze.
Amalensi okuxhumana e-Bifocal awuhlobo lwamalensi okuxhumana amaningi.Lokhu kusho ukuthi banemiyalelo eminingi yelensi yokuxhumana eyodwa.Kunezinhlobo eziningana ezahlukene ukuze ivumelane nezidingo ezahlukene.
Ukuthintana kwe-Bifocal (noma okuxubile) kuvame ukusetshenziselwa ukulungisa i-presbyopia ehlobene neminyaka.I-Presbyopia yisimo esenzeka kuwo wonke umuntu, ngokuvamile phakathi kweminyaka engama-40.
Lokhu kusho ikhono elincishisiwe lokugxila ezintweni eziseduze, ezifana nezinto zokufunda noma ukuthumela i-imeyili kufoni yakho.
Ukuxhumana okuxubile kuyasetshenziswa futhi ukuze kulungiswe i-astigmatism kanye namaphutha e-refrection afana nokubona eduze (ukubona eduze) nokubona kude (ukubona kude).
Zikuvumela ukuthi ugxile ezintweni eziseduze nezikude namehlo akho.Ngakho, balungisa kokubili ukubona eduze nokubona kude ngesikhathi esisodwa.
Amalensi okuxhumana e-Bifocal anezindlela ezihlukene zokuhlanganisa incwadi yakho kadokotela.Izinhlobo ezimbili ezivame kakhulu yilezi:
Izindleko zamalensi zincike kakhulu ohlotsheni lwawo.Amalensi ama-multifocal ngokuvamile abiza kakhulu kunamalensi okuxhumana ajwayelekile.
Uma ungenawo umshwalense, kungase kudingeke ukhokhe phakathi kuka-$700 no-$1,500 ngonyaka ukuze uthole amalensi.
Uma unomshwalense wombono obanzi futhi udokotela wakho ukhava ukuchayeka okushiwo udokotela, angase futhi amboze ukuchayeka okuningi.Kwezinye izimo, ungase udingeke ukuthi wenze inkokhelo eyengeziwe noma udonse imali ehlobene nezindleko zamalensi akho.
Amalensi okuxhumana kulolu hlu akhethiwe ngoba enziwe ngokunethezeka nokucaca kombono engqondweni, kanye nezinto zokwakha kanye nemiklamo esetshenzisiwe.
Sifuna amalensi abukeka emuhle emehlweni ethu ngisho nangezinsuku ezinde.Angaba namanzi amaningi noma avumele umoya-mpilo ukuthi udlule ngokukhululeka.Ezinye zazo zenzelwe ngokukhethekile ukukhulula izimpawu zamehlo omile.
Lawa ma-lens anyanga zonke enziwa ngobuchwepheshe be-CooperVision Aquaform.Umkhiqizo uthi le nto isiza ukugcwalisa amehlo futhi inikeze amehlo akho i-oxygen engu-100% ayidingayo.Ababuyekezi bavuma kakhulu ukuthi bathola lawa lens ekhululekile futhi ehlanzekile.
I-Biofinity multifocal contact lens ingaphinda iguqule indawo yokulungiswa ukuze ivumelane nencwadi yakho kadokotela.
Lawa macontact lens alahlwa nyanga zonke afaka ubuchwepheshe be-MoistureSeal®.Aqukethe amanzi angama-46% futhi alungele abantu abaphethwe amehlo omile.Zenziwe nge-Samfilcon A, into esiza ilensi ngayinye igcine umswakama.Ngokusho komkhiqizi, lawa ma-lens agcina umswakama ongu-95% amahora angu-16.Abasebenzisi baqaphele ukuthi lawa ma-lens awashi noma awashi ngisho nangemva kokusetshenziswa isikhathi eside.
Lawa ma-lens aklanyelwe ukwelapha i-presbyopia, ukungakwazi okungokwemvelo okuhlobene nobudala ukugxila ezintweni eziseduze.Ngoba lokhu kwenza kube nzima ukubona izinto ezincane ezifana namalensi okuxhumana acacile, laba abathintwayo baluhlaza okwesibhakabhaka.
Izibuyekezo eziku-inthanethi zisho ukuthi lawa ma-lens anikeza induduzo ngisho noma egqokwe usuku lonke.Futhi zenzelwe ukunciphisa isipoki nokucwayiza ekukhanyeni okuphansi, okuzenza zilungele ukushayela ebusuku.
Lawa ma-lens alahlwa nsuku zonke enziwe nge-silicone hydrogel (i-comfilcon A kulokhu) evumela umoya-mpilo ukuthi udlule ngokukhululeka ku-cornea ukuze uthole ukunethezeka okwengeziwe.
Aqukethe amanzi angama-56%, ngakho-ke athambisa ngokwemvelo.Lawa ma-lens aphinde anikeze isivikelo se-UV.
Umkhiqizi usebenzisana nePlastic Bank ukuqoqa nokukhipha ipulasitiki yasolwandle ezindaweni ezisogwini.Ngephakethe ngalinye lamalensi e-clariti 1 athengisiwe, inani elifanayo lepulasitiki liqoqwa ogwini bese ligaywa kabusha.
Lawa ma-lens angase abe usizo kubantu abane-astigmatism.Futhi banamanzi amaningi, okwenza kube ukukhetha okulula kubantu abaphethwe amehlo omile.Ngokusho komkhiqizi, lawa ma-lens ahlinzeka ngamanzi angama-78% emehlweni ngemva kwamahora angu-16 okusetshenziswa.Leli izinga elifanayo neso lakho lemvelo.
Zenziwe nge-etafilcon A, impahla enethezekile ye-hydrogel lens eklanyelwe ukukhulisa ukufinyelela komoyampilo ku-cornea.
Okunye ukubuyekezwa kwe-inthanethi kwabantu abaphethwe amehlo omile bathi ama-lens akhululekile kakhulu ngisho nangezinsuku ezinde.Imiklamo ye-hydration, oxygenation kanye nelens inikeza umbono ocacile emabangeni ahlukene ekukhanyeni okukhanyayo nokufiphele.
Amalensi Okuxhumana Anemibala Anamandla
Lawa macontact lens athambile anyanga zonke angagqokwa ngokuqhubekayo kuze kube ubusuku obuyisi-6 futhi ayinketho enengqondo yalabo abahambayo.
Ilensi ngayinye yakhelwe ukwandisa amazinga omswakamo ebusweni beso, ngisho noma igqokwe isikhathi eside.Khumbula ukuthi i-American Academy of Ophthalmology ayincomi ukuthi ulale ngaphandle.
Abanye abantu bazobona izinguquko ezinhle ngokushesha, kanti abanye bazodinga amaviki ambalwa okugqokwa okuvamile ukuze bajwayele.
Nakuba kunezinhlobo eziningana ezihlukene zamalensi oxhumana naye amaningi, ungathola ukuthi awekho kuwo akulungele.Abanye abantu futhi bayeka ngokushesha ngaphambi kokuba amehlo abo abe nesikhathi sokujwayela ukushintsha phakathi kwamaresiphi.
Unalokho engqondweni, thola ukuthi ukufaka ilensi yokuxhumana kufakiwe yini entengweni yokufaka lens yokuxhumana.Ngakho, ungazama izinhlobo eziningi ngaphambi kokuthenga.
Abanye abantu bathola ukuthi ukuchayeka kwe-multifocal kuthinta kabi umbono wabo wokujula, okwenza kube nzima ukuwagqoka.
Abanye bakhononda ngamehlo akhathele, ikhanda noma ama-halos.Lokhu kungenzeka kakhulu kulabo abafunda kakhulu kuma-computer, noma labo abashayela amabanga amade, ikakhulukazi ebusuku.
Uma unamehlo omile, ukugqoka ama-contact lens amaningi kungase kungakhululeki.Kodwa-ke, abantu abaningi abanalesi simo bathi bazizwa bekhululekile ngokuchayeka kwe-multifocal emanzini aphezulu.
Yebo.Njengama-bifocal, amalensi okuxhumana amaningi akuvumela ukuthi ubone eduze nakude.Khumbula ukuthi ungathola ijika lokufunda nganoma yiluphi uhlobo lwezibuko ze-multifocal.Uma usuyitholile i-hang yayo, uzokwazi ukubona ngokucacile ngelensi yakho kungakhathaliseki ukuthi ugxile kuphi.
Uma ungakaze ugqoke amalensi e-hyperfocal ngaphambilini, kungase kukuthathe kufika emavikini angu-2 noma ngaphezulu ukuze ufunde ukuwagqoka ngokunethezeka.Iqhinga liwukuba uzigqoke usuku lonke ngaphandle kokubuyela ezingilazini zakho ezindala.Uma unamathela kuzo, kufanele uzijwayeze ngokuhamba kwesikhathi.
Abanye abantu bakhononda ngokuhlanekezela okubukwayo kanye nokuphazamiseka kwensimu ebonakalayo lapho begqoke ama-bifocal.Kuze kube yilapho usuzijwayele, kuzoba nzima ukuthi ubheke phansi, isibonelo, lapho wehla ngezitebhisi.Amalensi e-Bifocal nawo awanikezi inkambu yokubuka efanayo njengamalensi aqhubekayo (ama-multifocal lens).Ngokungafani nama-bifocal, anezigaba ezimbili zokubona (eduze nakude), ama-multifocal anezintathu (eduze, maphakathi nakude).Kwabanye, lokhu kunikeza inguquko ebushelelezi.
Uma uthanda, ungasebenzisa amapheya amabili ezibuko ahlukene ukuze ubone eduze nakude, esikhundleni samalensi okuxhumana amaningi.Ungakwazi futhi ukuxoxa nge-multifocal lens ne-ophthalmologist yakho.
Amalensi okuxhumana e-Bifocal asetshenziselwa ukwelapha izinkinga ezihlukahlukene zokubona, okuhlanganisa i-presbyopia kanye nokubona eduze.
Amalensi okuxhumana e-Bifocal adinga incwadi kadokotela futhi angathengwa kumasayithi e-inthanethi wabathengi ahlukahlukene kanye nezitolo zamehlo.
Ochwepheshe bethu bahlala beqapha indawo yezempilo nokuphila kahle futhi babuyekeza ama-athikili ethu njengoba ulwazi olusha lutholakala.
