Uma ugqoka ama-contact lens, awuwedwa.Eqinisweni, uma use-US, ungomunye wabantu abangaba yizigidi ezingu-45 abagqoka amalensi okuxhumana esikhundleni sezibuko (ngokwe-CDC), futhi ungomunye wabantu abaningi emhlabeni jikelele.Inzuzo yombono ocacile abawunikezayo.
Amalensi okuxhumana ayindlela elula yokuthuthukisa umbono wakho nsuku zonke, kodwa kubantu abaningi, ukuwagqoka kungashintsha isigqi sawo.Kodwa-ke, noma yini ehilela ukufaka okuthile ngqo esweni lakho nsuku zonke ifika nesethi yayo yezinselelo: lapho uqala ukusebenzisa kabi ama-contact lens, izinto zingase zingahambi kahle.
Kodwa ukugqoka ama-contact lens akufanele kube yiphupho elibi.Eqinisweni, kungenzeka ukuthi usunomkhuba owenza amalensi okuxhumana abe nzima kunalokho okufanele abe yikho.Ngalawa macebiso alula, ungaqinisekisa ukulingana okuvikelekile, unwebe impilo, futhi ugcine amehlo akho enempilo.Ake sibheke amathiphu ethu aphezulu kwabasebenzisa amalensi okuxhumana.
Ngaphambi kokuthi uqale ukucabanga ngokugqoka amalensi okuxhumana, kunento eyodwa futhi okudingeka uyinqume: inhlanzeko yezandla.
Ngokocwaningo olwenziwe yiKholeji Lodokotela Bamehlo (ngokusho kwe-Optometry Namuhla), kubaluleke kakhulu ukugeza izandla zakho ngaphambi kokuthinta amalensi, kodwa cishe u-30% wabantu abakwenzi nhlobo.Lena inkinga enkulu.Udokotela wamehlo uDaniel Hardiman-McCartney uthi: “Ukugeza izandla futhi uzomise kahle kuzonciphisa amathuba akho okuthola isifo esiyingozi futhi esingase sibe yingozi emehlweni.Amagciwane angangena emehlweni akho evela ezandleni zakho futhi abangele izinto ezimbi.
Xhumana Nesixazululo Selensi
isixazululo?Geza izandla abantu.Qala ngokucwilisa izandla zakho emanzini ngokucophelela, bese uhlikihla insipho phakathi kwezandla zakho bese uhlikihla iminwe yakho (ngokusho kwe-Eyeland Opticians).Bese udlulela ezihlakaleni futhi uhlikihle isihlakala ngasinye ngesandla esinensipho, bese ugxila ngemuva kweminwe nezithupha.Okokugcina, hlanza ngaphansi kwezipikili ngokuhlikihla izipikili ngokunyakaza okuyindilinga entendeni yesandla sakho, bese uhlanza izandla zakho kahle futhi uzomise kahle.hey shesha!Ungahamba manje!
Amalensi okuxhumana ayindlela elula yokugcina umbono wakho we-20/20, kodwa masibhekane nakho, awashibhile.Ukugqokwa kwamalensi okuxhumana okuvamile kungakubiza kufikela ku-$500 ngonyaka, kuye ngohlobo lwamalensi okuxhumana owasebenzisayo, ngokusho kwe-Healthline.Ngakho-ke akumangazi ukuthi abantu bahlale befuna izindlela zokunciphisa izindleko, futhi ungacabanga ngesixazululo selensi yokuxhumana njengokunciphisa izindleko okungadingekile.Nokho, sikudikibalisa kakhulu lokhu.
Isixazululo selensi yokuxhumana sibalulekile ukuze ugcine amalensi akho ehlanzekile futhi evikelekile ekuthelelekeni, futhi ukushintshela emanzini kungaba nemiphumela emibi eminingi empilweni yamehlo akho (ngokwe-CDC).Izixazululo zenhloso yonke zifanele abantu abaningi futhi zingahlanza ngempumelelo futhi zibulale amagciwane amalensi, kodwa qaphela ukusebenzisa isixazululo esisha njalo uma ushintsha amalensi.Uma ungabekezeleli noma ungezwani nezixazululo zomhlaba wonke, udokotela wakho wamehlo angakunikeza isisombululo se-hydrogen peroxide, kodwa kufanele usisebenzise ngendlela efanele (ulandela imiyalelo kadokotela wakho wamehlo) ukuze ugweme ukucasuka kwamehlo.
Izithako ezinosawoti nazo zisetshenziswa kakhulu, kodwa qaphela ukuthi azinazo izinto zokubulala amagciwane futhi zingasetshenziswa kuphela nezinye izixazululo.
Kulula ukucabanga ukuthi ukuthinta ukuthinta, futhi ngokuvamile bonke abantu bajwayele ukugqoka yilokho abakugqoka impilo yonke.Kodwa kunezinhlobo eziningi ezahlukene zamalensi okuxhumana, futhi ukwazi izitayela ezahlukene kuzokusiza wenze ukukhetha okungcono kakhulu kwezidingo zakho ngabanye.
Ngokuvamile, abantu bagqoka amalensi okuxhumana athambile, awela emakamu amabili ahlukene: ukugqokwa okulahlwayo nokunwetshiwe (ngokwe-FDA).Amalensi okuxhumana alahlwayo akhethwa abantu abaningi ngokuvamile asetshenziswa nsuku zonke futhi ngokuvamile alahlwa ngemva kokusetshenziswa kokuqala.Ngakolunye uhlangothi, amalensi okuxhumana agqoke isikhathi eside amalensi aklanyelwe ukusetshenziswa isikhathi eside, kusukela ngobusuku obumbalwa kuya enyangeni.Yize amalensi okuxhumana agqokwa isikhathi eside ewusizo kubathengi abajwayelekile, awukwazi ukuwagqoka kaningi njengoba amehlo akho ephumula.
Nokho, izibopho ezithambile azizona kuphela inketho etholakalayo.Oxhumana nabo bengilazi eqinile (noma i-RGP) abavumeleka kalula banganikeza abasebenzisi ukucaca okubonakalayo okuphelele futhi bangase babe bushelelezi kunozakwabo abathambile.Nokho, angase angawabekezeleli kangako amehlo futhi kungase kuthathe isikhathi ukuwajwayela.
Uma ungumuntu othanda umuntu ngamunye, siyasithanda isitayela sakho.Ungumphefumulo okhululekile, uphila onqenqemeni, awuboshiwe ngemithetho ndoda.Kodwa uma sikhuluma iqiniso, ngisho noma uwuhlobo oluzishintsha nsuku zonke, indawo eyodwa akufanele unake ngempela ukuthi isimo esikhona siwuhlelo lwakho lokuxhumana namalensi.Ukunamathela ku-contact lens ukugqoka isimiso kuzokusiza ukuthi ukwenze ngokuphepha ngaso sonke isikhathi—futhi okubaluleke kakhulu, ungawahlanganisi amalensi okudingeka uwagqoke esweni ngalinye—njengokusho kwencwadi yakho kadokotela (ngokweWebMD).
Okokuqala, beka i-lens yokuxhumana yeso lokuqala phambi kwakho, bese ususa ngokucophelela ilensi ukusuka ecaleni uye phakathi kwentende yesandla sakho.Ngemuva kokugeza ngesisombululo, sisebenzise eminweni yakho, okungcono emunweni wakho wenkomba.Bese, ngesinye isandla sakho, vula iso lakho phezulu bese ubeka omunye umunwe esandleni sakho selensi yokuxhumana, usigcine sivulekile ngaphansi.Beka i-lens ngobumnene ku-iris, uslayide uyibuyisele endaweni uma kunesidingo, bese ucwayiza kancane.Uma uthanda, vala amehlo akho bese uhlikihla kahle.Uma ilensi isigxilile esweni lakho, phinda wenze enye ilensi.
Manje ngeke sicashe izinto lapha: ukugqoka amalensi okuxhumana okokuqala kuwumsangano.Thatha isigqoko esincane usibeke phezu kwamehlo akho?Uxolo, kodwa manje akusona isikhathi esingcono kakhulu, njengoba abantu abaningi becabanga.Kungakho, njengoba ochwepheshe bakwa-CooperVision besho, uma ungumuntu oqala ngqa ukusebenzisa amalensi okuxhumana, kubalulekile ukuthi uphumule futhi uyithathe kancane.
Kubonakala sengathi okubi kakhulu kungenzeka ngokwemvelo (okungukuthi i-lens iyanyamalala ngemuva kwehlo futhi ilahleke unomphela), kodwa sithembe, lokhu ngeke kwenzeke.Uma unovalo, kunezinto ezimbalwa ongazenza ukuze ubhekane nokwesaba kwakho.Njengoba ochwepheshe bakwa-PerfectLens batusa, ngaphambi kokuthi uqale ukusebenzisa amalensi akho, zama “isivivinyo sokugijima” lapho uzilolongela khona ukufaka amalensi akho ngaphandle kokuwafaka.Lokhu kuzokusiza ukuthi ujwayele ukuthinta amehlo akho futhi unciphise ukwesaba ngakho.Yebo, vele uqiniseke ukuthi izandla zakho zihlanzekile.
Kungase futhi kube usizo ukuchitha isikhathi esithile uvule amehlo akho, njengokungathi ufaka amalensi okuxhumana, ukuze ujwayele ukungacwayizi, okungaba usizo lapho ufaka amalensi.
Uma kuziwa ekunakekelweni okufanele kwelensi yokuxhumana, ukuwahlanza kahle kuyinto ebaluleke kakhulu okudingeka ufunde ukwelula impilo yamalensi othintana naye futhi uvikele impilo yamehlo akho.Kodwa inkinga ukuthi ezikhathini eziningi sifundiswa kuphela lapho sithintana nabo bokuqala futhi singaphinde siphinde.
Yingakho sicabange ukuthi kungaba wusizo ukuphinde siwuhlephule.Qinisekisa ukuthi izandla zakho zihlanzekile futhi zomile ngaphambi kokuphatha noma ukukhipha amalensi, kusho udokotela wamehlo u-Rachel M. Keywood (nge-Dean McGee Eye Institute).Uma ususa amalensi akho, qiniseka ukuthi noma yiziphi izixazululo zokuhlanza ezindala ozisebenzisayo ziyalahlwa ukuze ungaxubi ezindala nezintsha.Khona-ke kufanele uhlanze icala ngesisombululo sokuhlanza bese usula ngethawula lephepha.Susa ilensi uyibeke entendeni yesandla sakho, bese wengeza amaconsi ambalwa esixazululo bese usula kancane.Bese ulibeka kukesi bese uligcwalisa ngesisombululo sokuhlanza ukuze usifake emanzini.Uma kungenzeka, kufanele futhi usebenzise ikesi elisha njalo ngenyanga.
Ngakho-ke nguwe ogqoka izibuko, futhi okokuqala nithintana.Ufika engxenyeni yekhasi lewebhu lapho ubhala khona incwadi kadokotela, ucabanga ukuthi “Yebo, lezo yizibuko zami nje, kunjalo” bese uchofoza kukho ngaphandle kokungabaza.Noma mhlawumbe ukhohlwe incwadi kadokotela yengilazi yeso lakho – hey, lokho kungenzeka – kodwa uyaqagela nje.Kubi kangakanani?
Hhayi-ke, sincoma ukuthi ungakwenzi.Kubaluleke kakhulu ukugqoka amalensi okuxhumana ngendlela efanele kanye nokuhlinzeka nokuvuselela incwadi kadokotela yengilazi yamehlo kanye nencwadi kadokotela yengilazi yeso (nge-VisionDirect) njalo.Isizathu silula (ngokusho kwabakwaSpecsavers).Uma izibuko zakho zisemakhaleni akho, buqamama kancane namehlo akho, amalensi akho asemehlweni akho, okusho ukuthi kudingeka ahluke ngamandla ukuze ukwazi ukubona kahle.Uma uvele unikeze incwadi kadokotela yengilazi yemehlo kothintana naye, ukubona kwakho ngeke kube kuhle ngendlela okulindeleke ngayo.Kubalulekile futhi ukukhumbula ukuthi, njengokugqoka izibuko, incwadi kadokotela ingase yehluke ngeso ngalinye.
Kungokwemvelo ukuthi abantu babe novalo kancane ngalokho okusemehlweni abo, ikakhulukazi lapho bewathinta futhi ikakhulukazi lapho bezama ukudoba okuthile kuwo.Kodwa-ke, ngokufunda ukuthi ungawasusa kanjani ngokuphephile amalensi othintana naye ngaso sonke isikhathi, uzonciphisa kakhulu ukukhathazeka okuzungeze amabhola wamehlo akho ayigugu.
Okokuqala, qiniseka ukuthi izandla zakho zihlanzekile ngokuphelele futhi zomile (ngokusho kweWebMD).Thatha isandla sakho esingalawuleki (ongasisebenziseli ukubhala) bese usebenzisa umunwe wakho ophakathi nendawo noma wokukhomba ukuze udonsele ijwabu leso elingaphezulu liye phansi.Bese, ngomunwe ophakathi kwesinye isandla, donsa ijwabu leso elingezansi liye phansi.Umgomo uwukuveza kakhulu iso lakho ngangokunokwenzeka ukuze amalensi akho kube lula ukuwakhipha.Cindezela kancane i-lens yokuxhumana phakathi kwesithupha nomunwe wangaphambili wesandla sakho esiphethe ukuze uyisuse futhi uyikhiphe.Uma lokhu kunzima kancane, sebenzisa umunwe wakho wenkomba esikhundleni sokuwushelela phansi kwenhlamvu yeso bese uyimpintsha.Yenza okufanayo nangelinye iso futhi ugcine amalensi okuxhumana uma usuwakhiphile.
Noma ubani obone ibhokisi lamalensi oxhumana naye angase adideke kancane ukuthi kusho ukuthini konke okukulo.Liyini ijika lesisekelo?Ingabe ububanzi buyi-diameter yeso lakho, noma ububanzi be-lens yokuxhumana, noma ububanzi bomhlaba, noma enye into?
Nokho, ngokubonga, akudingeki ube udokotela wamehlo ukuze uqonde ukuthi la magama angaqondakali asho ukuthini.Ama-contact lens akho angenziwa kusetshenziswa izigaba ezintathu eziyinhloko: ama-diopter, i-base curvature, kanye nobubanzi (ngokuvumelana ne-Vision Direct).Ngokwezwi nezwi, i-diopter ibhekisela emandleni anqunyiwe e-lens, kuyilapho i-base arc iwukugoba kweso okumele lifane nelensi ngokuseduze ngangokunokwenzeka ukuze lilingane kahle.Ububanzi, ngakolunye uhlangothi, bubhekisela ebubanzini belensi.Uma une-astigmatism, cishe unezinye izigaba ezimbili: amasilinda nama-ekseli.I-eksisi isho i-engeli yokulungiswa edingekayo ukuze kuzuzwe umugqa wokubona, futhi isilinda isho ukuthi udinga ukulungisa okungakanani okwengeziwe.
Nakuba ungakwazi ukugqoka izibuko zelanga kuze kushone ilanga, amalensi okuxhumana azoshintshwa nsuku zonke ukuphila kwakho konke.Uma kubhekwa ukuthi ama-contact lens ayizinto ezibekwe ngqo ku-cornea, kubalulekile ukunikeza amehlo akho isikhathi esincane sokuphefumula ngezikhathi ezithile - ngokoqobo.
Ngokusho kweDean McGee Eye Institute, ukugqoka ama-contact lens kuvimbela ukugcwala komoyampilo esweni, okungaholela ekuvuvukeni kwamehlo.Ngakho-ke, singakanani isikhathi ngaphandle kokuxhumana okufanele usinikeze emehlweni akho usuku ngalunye?Ngokuvamile inkinga ixazululwa phakathi namahora ambalwa.“Ngincoma ukukhipha amalensi okuxhumana ihora noma amabili ngaphambi kokulala ukuze unikeze amehlo akho ukuphumula,” kusho udokotela wamehlo uRachel M. Keywood.Futhi qiniseka ukuthi awulali koxhumana nabo.“Kubalulekile ukufaka izibuko ngemva kokukhipha ama-contact lens,” kunezela uCaywood, “lokhu kuqinisekisa ukuthi umbono wakho uhlala ucacile ngaphandle kwesidingo sokuhlala unamathisele amalensi ku-cornea.
Xhumana Nesixazululo Selensi
Ingabe uyazikhumbula izinsuku lapho, lapho useyingane, wawukwazi ukucwila echibini, uvule amehlo akho ngaphansi kwamanzi, futhi ubhukude ngendlela ebukekayo futhi ungaboni kahle (kahle, uphelelwe yi-chlorine emehlweni akho)?Wonke umuntu uyakwenza.
Ngakho-ke kwabasebenzisa amalensi okuxhumana, kungokwemvelo ukucabanga ukuthi uma usukhumule izibuko zakho, uzokwazi ukwenza into efanayo futhi.Ngeshwa, ukubhukuda oxhumene nabo kungenye yezinto ezimbi kakhulu ongayenza empilweni yamehlo (ngokwe-Healthline).Lokhu kungenxa yokuthi amalensi akho empeleni asebenza njengesicupho sanoma yimaphi amagciwane noma amagciwane acashe emanzini, okuthi, ngonya, angakwazi ukubulawa ngokuphelele yi-chlorination.Uma ubhukuda, lezi zinambuzane eziwuhlupho zingangena kumalensi anezimbotshana, zithintane namehlo akho, futhi zihlale lapho, zandise amathuba okutheleleka kwamehlo, ukucasuka, ngisho nezilonda ze-cornea.Futhi qaphela ukuthi ukubhukuda emanzini ahlanzekile kungaba kubi kakhulu kunokubhukuda echibini, njengoba amanzi emvelo angaqukatha amagciwane amaningi amehlo akho angakwazi ukumelana nawo.
Kube usuku olude.Ubusebenza ngaphandle, uke waya endaweni yokucima ukoma, manje ukhathele.Endaweni ethile, uyakhohlwa ukuthi unabo oxhumana nabo - ngaphandle kwalokho ngeke ukwazi ukubathola.Hhayi, akukho ukwahlulela lapha, yilokho kuphela.Kodwa kuwumsebenzi wethu ukukuxwayisa ukuthi ingozi yokulala kumalensi othintana naye ngeke iwazuzise amehlo akho futhi ingase ibe yingozi kakhulu.
“Ukulala kuma-contact lens kuyingozi emehlweni ngoba kunciphisa inani lomoya-mpilo ofinyelela kumangqamuzana e-cornea,” kuxwayisa udokotela wamehlo u-Rachel M. Caywood (nge-Dean McGee Eye Institute).Uma lokhu kwenzeka, imithambo emisha yegazi iqala ukwakheka ku-cornea yakho noma imihuzuko bese kuvela ukucasuka, okwandisa amathuba okutheleleka.Nakuba ezinye izifo zamehlo zingaba mnene futhi zingalindelekile, ezinye zingalimaza kakhulu umbono wakho.
Ngakolunye uhlangothi, amanye amalensi okuxhumana angase aklanywe ukuthi agqokwe ebusuku.Kodwa-ke, uma lokhu kuyindaba yakho, qiniseka ukuthi ulandela imiyalelo ethile udokotela wamehlo wakho akunika yona.
Amehlo, njengazo zonke ezinye izitho zomzimba, awenwa amanzi.Ngezinye izikhathi izimbungulu ezimbi noma amagciwane angangena emehlweni akho, okuvamise ukuba maningi amathuba okuba ugqoke amalensi okuxhumana (ngokwe-American Academy of Ophthalmology).
Esinye isifo okufanele sibhekwe yi-keratitis, ukutheleleka kwe-cornea.Lokhu kungase kube ngenxa yokungawasebenzisi kahle amalensi okuxhumana, ukulala kuwo, noma ukuwahlanza ngendlela engafanele, futhi kuvame kakhulu kubantu abasebenzisa amalensi okuxhumana esikhathi eside.Ungabona ubuhlungu beso noma ukucasuka, ukubona lufifi, kanye nokuzwela okungenzeka.Nakuba i-keratitis ingahamba kalula, kwezinye izimo ingaba nzima kakhulu futhi iholele emazingeni e-cornea.Kulezi zimo, ukuhlinzwa noma ukufakelwa kwe-cornea kungase kudingeke ukuze kubuyiselwe umbono.
Kodwa-ke, ungawanciphisa kakhulu amathuba okuthola isifo samehlo uma ulandela izinqubo zokuphatha amalensi oxhumana naye, uwaphathe kahle, uwahlanze futhi uwashintshe njalo.
Ngokusho kweCleveland Clinic, wonke amehlo ahlukile (ukholwa noma ungakholwa, wena kanye nombala wamehlo akho kuphela ohlukile) futhi ayahluka kakhulu ngendlela ome ngayo.Uma amehlo akho engekho manzi kakhulu, lokhu kungase kukwenze ube novalo mayelana nokugqoka amalensi okuxhumana.Nokho, uma unamehlo omile, awudingi ukugwema contact lens ngokuphelele.Udinga nje ukuthatha izinyathelo zokuphepha ezanele ukuze uqiniseke ukuthi uzigqoka ngokuphepha nangokunethezeka (nge-Specsavers).
Uma unamehlo omile, zama amalensi okuxhumana e-silicone hydrogel, anikeza umoya-mpilo emehlweni akho futhi awagcine enomswakama.Ungase futhi uthande ukucabangela ukugcina amehlo akho isikhathi eside usuku ngalunye ngaphandle kwamalensi okuxhumana ukuze akwazi ukubuyisela amanzi ngemva kokugqoka amalensi.Qiniseka ukuthi uyigcina ihlanzekile;ungakwazi futhi ukugwema izixazululo ze-hydrogen peroxide, ezingabangela ukungakhululeki okwengeziwe.
Kodwa-ke, uma uqhubeka uzizwa womile, khuluma nodokotela wakho mayelana nomthelela nokuthi kufanele ubheke kanjani amehlo akho esikhathini esizayo.
