Kubantu abanenkinga yokubona, ziningi izindlela zokulungisa ukubona nokuthuthukisa impilo yamehlo.Abantu abaningi bakhetha amalensi okuxhumana noma izibuko ngoba alula futhi ayashesha.Nokho, kukhona nezinketho zokuhlinzwa.
Lesi sihloko siqhathanisa ama-contact lens nezibuko, izinzuzo kanye nokubi ngakunye, nezici okufanele zicatshangelwe lapho ukhetha izibuko.
Izibuko zigqokwa ebhulohweni lekhala ngaphandle kokuthinta amehlo, futhi amalensi okuxhumana agqokwa ngqo emehlweni.Abasebenzisi bangashintsha amalensi okuxhumana nsuku zonke noma bawagqoke isikhathi eside ngaphambi kokuba bawakhiphe ukuze bawahlanze.Kodwa-ke, ukugqoka amalensi okuxhumana isikhathi eside kungandisa ingozi yokutheleleka kwamehlo.
Njengoba izibuko ziqhelelene kancane namehlo futhi amalensi okuxhumana abekwe ngqo phezu kwamehlo, incwadi kadokotela ihlukile kuwo wonke umuntu.Abantu abafuna ukugqoka izibuko kanye namalensi okuxhumana ngesikhathi esifanayo badinga imiyalelo emibili.I-ophthalmologist ingahlola umthamo wayo yomibili le mithi ngesikhathi sokuhlolwa kwamehlo okuphelele.
Kodwa-ke, odokotela bamehlo badinga ukukala ukugoba nobubanzi beso ukuze baqinisekise ukuthi i-lens yokuxhumana ilingana ngendlela efanele.
Abantu abanemiyalelo yelensi yokuxhumana kanye nemiyalelo yengilazi yamehlo badinga ukuvuselelwa njalo.Kodwa-ke, abagqoka amalensi okuxhumana bazodinga ukuhlolwa kwamehlo kwaminyaka yonke ngudokotela wamehlo, udokotela wamehlo, noma udokotela wamehlo.Ngokuphambene, abantu abagqoka izibuko bangase bangadingi ukuvuselela incwadi kadokotela noma ukuhlolwa kwamehlo kaningi njengoba benza manje.
Uma kuziwa ekukhetheni, abagqoki bezibuko zamehlo banokuningi abangakhetha kukho, okuhlanganisa ilensi nezinto zohlaka, osayizi bozimele, izitayela nemibala.Bangaphinde bakhethe amalensi amnyama elangeni noma amalensi anciphisa ukuxhopha ngenkathi besebenza kukhompyutha.
Abagqoki belensi yokuxhumana bangakhetha phakathi kwamalensi okuxhumana ansuku zonke, amalensi okuxhumana agqokwa isikhathi eside, amalensi aqinile nathambile, ngisho namalensi anombala ukuze ashintshe umbala weiris.
Cishe u-90% wabasebenzisa lens yokuxhumana bakhetha amalensi okuxhumana athambile.Kodwa-ke, izazi zamehlo zingancoma amalensi aqinile kubantu abane-astigmatism noma i-keratoconus.Lokhu kungenxa yokuthi lezi zimo zingaholela ekungalingani kwe-cornea.Amalensi aqinile angakulungisa lokhu ukuze anikeze umbono ocacile.
I-American Academy of Ophthalmology (AAO) yeluleka abagqoka lens yokuxhumana ukuthi bacabange ukushintshela ezingilazini ngesikhathi sodlame lwe-coronavirus.Abagqoki be-lens yokuxhumana bavame ukuthinta amehlo abo kaningi, nakuba kungekho bufakazi bokuthi maningi amathuba okuba bahlakulele lesi sifo.I-coronavirus entsha ingasakazeka emehlweni, ngakho ukugqoka izibuko kungasiza ekuvimbeleni ukutheleleka.
Abantu abaningi bagqoka izibuko noma amalensi ukuze bathuthukise umbono wabo.Idatha etholakalayo iphakamisa ukuthi cishe abantu abayizigidi ezingu-164 e-United States bagqoka izibuko futhi abangaba izigidi ezingu-45 bagqoka amalensi okuxhumana.
Lapho ukhetha phakathi kwabo, abantu bangacabangela indlela yabo yokuphila, izinto abazithandayo, ukunethezeka kanye nezindleko.Isibonelo, ama-contact lens kulula ukuwagqoka uma esebenza, awafaki inkungu, kodwa maningi amathuba okuba abangele izifo zamehlo.Izibuko ngokuvamile zishibhile futhi kulula ukuzigqoka, kodwa zingaphulwa noma zibekwe kabi ngumuntu.
Noma, nakuba kungase kube inketho ebiza kakhulu, abantu bangashintshanisa izibuko namalensi okuxhumana njengoba kudingeka.Kungase futhi kufiseke ukuvumela abasebenzisi bokuxhumana ukuthi bathathe ikhefu koxhumana nabo noma lapho bengakwazi ukugqoka abathintwayo.
Ukuhlolwa kwamehlo njalo kubalulekile empilweni yamehlo.I-American Academy of Ophthalmology (AAO) incoma ukuthi bonke abantu abadala abaneminyaka ephakathi kuka-20 no-30 bahlole ukubona kwabo njalo ngemva kweminyaka emi-5 kuya kweyi-10 uma bebona kahle futhi benempilo.Abantu abadala asebekhulile kufanele bahlolwe amehlo lapho sebeneminyaka engama-40 ubudala, noma uma benezimpawu zokungaboni noma umlando womndeni wokungaboni kahle noma izinkinga zokubona.
Uma abantu behlangabezana nanoma yiziphi izimo ezilandelayo, kungakhathaliseki ukuthi banencwadi kadokotela yamanje, kufanele babonane nodokotela wamehlo ukuze ahlolwe:
Ukuhlolwa kwamehlo okuvamile kungathola nezimpawu zokuqala zezinye izifo, njengomdlavuza othile, isifo sikashukela, i-cholesterol ephezulu, nesifo samathambo.
Ukuhlinzwa kwamehlo nge-laser kungaba enye indlela ephumelelayo nehlala njalo yokugqoka izibuko noma amalensi okuxhumana.Ingozi yemiphumela emibi iphansi, ngokusho kwe-AAO, futhi amaphesenti angu-95 alabo abenza inqubo babika imiphumela emihle.Nokho, lolu hlelo akulona olwawo wonke umuntu.
I-PIOL ilensi ethambile, enwebekayo efakwa odokotela abahlinzayo ngqo esweni phakathi kwelensi yemvelo neiris.Lokhu kwelashwa kufanelekile kubantu abanemigomo ephezulu kakhulu ye-astigmatism nezibuko zamehlo.Ukuhlinzwa kwamehlo kwe-laser okulandelayo kungathuthukisa umbono.Nakuba lokhu kungaba inqubo ebizayo, kungase kushibhe kunezindleko zokuphila konke zokugqoka izibuko noma amalensi okuxhumana.
Lokhu kwelashwa kuhilela ukugqoka amalensi okuxhumana aqinile ebusuku ukuze kusize ukulungisa kabusha i-cornea.Lesi isilinganiso sesikhashana sokuthuthukisa umbono wosuku olulandelayo ngaphandle kosizo olwengeziwe oluvela kumalensi noma izibuko.Ifanele abantu abane-astigmatism.Kodwa-ke, uma ogqokile eyeka ukugqoka amalensi ebusuku, zonke izinzuzo bezibuyiselwa emuva.
Izibuko namalensi okuxhumana asiza ukuthuthukisa ukubona, futhi ngayinye inobuhle bayo nobubi bayo.Abasebenzisi bangafisa ukucabangela ibhajethi, izinto zokuzilibazisa, nendlela yokuphila ngaphambi kokukhetha phakathi kwazo.Imikhiqizo eminingi nezinsizakalo zinikeza izinketho ezifanele kakhulu.
Kungenjalo, kungase kucatshangelwe izixazululo zokuhlinzwa ezinomphela ezifana nokuhlinzwa kwamehlo nge-laser noma amalensi afakiwe.
Izindleko zamalensi okuxhumana zincike ohlotsheni lwamalensi, ukulungiswa kombono okudingekayo nezinye izici.Qhubeka ufunde ukuze uthole okwengeziwe, okuhlanganisa namathiphu okuphepha.
Amalensi okuxhumana ansuku zonke nanyanga zonke ayafana, kodwa ngalinye linobuhle nobubi balo.
