Kubantu abaneengxaki zombono, zininzi iindlela zokulungisa umbono kunye nokuphucula impilo yamehlo.Abantu abaninzi bakhetha iilensi zoqhagamshelwano okanye iiglasi kuba zikhanya kwaye ziyakhawuleza.Nangona kunjalo, kukho kwakhona ukhetho lotyando.
Eli nqaku lithelekisa iilensi zoqhagamshelwano kunye neeglasi, izinto eziluncedo nezingeloncedo ngakunye, kunye nezinto ekufuneka ziqwalaselwe xa ukhetha iindondo.
Iiglasi zinxitywe kwibhulorho yempumlo ngaphandle kokuchukumisa amehlo, kwaye iilensi zokunxibelelana zinxibe ngqo emehlweni.Abasebenzisi banokutshintsha iilensi zoqhagamshelwano mihla le okanye bazinxibe ixesha elide ngaphambi kokuba bazisuse ukuze zicocwe.Nangona kunjalo, ukunxiba iilensi zokunxibelelana ixesha elide kunokonyusa umngcipheko wosulelo lwamehlo.
Ekubeni iiglasi zikude kancinane emehlweni kwaye iilensi zoqhagamshelwano zibekwe ngokuthe ngqo phezu kwamehlo, umyalelo wahlukile kumntu wonke.Abantu abafuna ukugqoka iiglasi kunye nee-lens zoqhagamshelwano ngexesha elifanayo bafuna imiyalelo emibini.I-ophthalmologist inokuvavanya idosi yazo zombini iziyobisi ngexesha lovavanyo olubanzi lwamehlo.
Nangona kunjalo, i-ophthalmologists nayo kufuneka ilinganise i-curvature kunye nobubanzi beso ukuqinisekisa ukuba i-lens yoqhagamshelwano ihambelana ngokuchanekileyo.
Abantu abanemigqaliselo ye-lens yoqhagamshelwano kunye nemigqaliselo yeglasi yamehlo bafuna ukuhlaziywa rhoqo.Nangona kunjalo, abanxibe iilensi zoqhagamshelwano baya kufuna uvavanyo lwamehlo lonyaka yi-ophthalmologist, ophthalmologist, okanye i-optometrist.Ngokwahlukileyo koko, abantu abanxiba iindondo kusenokungafuneki ukuba bayihlaziye incwadi kagqirha okanye baxilongwe amehlo rhoqo njengoko besenza ngoku.
Xa kuziwa ekukhetheni, abathwali beglasi banokukhetha okuninzi, kubandakanya ilensi kunye nezixhobo zesakhelo, ubungakanani besakhelo, izitayile kunye nemibala.Basenokukhetha iilensi eziba mnyama elangeni okanye icoat enciphisa ilitha ngelixa besebenza ekhompyuter.
Abanxibe iilensi zoqhagamshelwano banokukhetha phakathi kweelensi zonxibelelwano zemihla ngemihla, iilensi zokunxibelelana ezinxibe ixesha elide, iilensi ezinzima nezithambileyo, kunye neelensi ezithathiweyo zokutshintsha umbala we-iris.
Malunga ne-90% yabantu abanxiba iilensi zoqhagamshelwano bakhetha iilensi ezithambileyo.Nangona kunjalo, i-ophthalmologists inokucebisa iilensi eziqinileyo kubantu abane-astigmatism okanye i-keratoconus.Oku kungenxa yokuba ezi meko zinokukhokelela kukungalingani kwe-corneal.Iilensi eziqinileyo zinokuyilungisa le nto ukunika umbono ocacileyo.
I-American Academy of Ophthalmology (AAO) icebisa abanxibe iilensi zoqhagamshelwano ukuba bacinge ngokutshintshela kwiiglasi ngexesha lobhubhani we-coronavirus.Abanxibe iilensi zoqhagamshelwano badla ngokuchukumisa amehlo abo rhoqo, nangona kungekho bungqina bokuba banako ukuphuhlisa eso sifo.I-coronavirus entsha inokusasazeka ngamehlo, ke ukunxiba iiglasi kunokuthintela usulelo.
Abantu abaninzi banxiba iiglasi okanye iilensi zokunxibelelana ukuphucula umbono wabo.Idatha ekhoyo ibonisa ukuba malunga ne-164 yezigidi zabantu e-United States banxiba iiglasi kwaye malunga ne-45 yezigidi banxiba iilensi zoqhagamshelwano.
Xa ukhetha phakathi kwabo, abantu banokuqwalasela indlela yabo yokuphila, izinto abazithandayo, intuthuzelo kunye neendleko.Umzekelo, ii-lens zoqhagamshelwano zilula ukunxiba xa zisebenza, azifaki inkungu, kodwa zinokubangela izifo zamehlo.Iiglasi zihlala zitshiphu kwaye kulula ukuzinxiba, kodwa zingophuka okanye zibekwe gwenxa ngumntu.
Okanye, ngelixa inokuba lolona khetho lubiza kakhulu, abantu banokutshintsha iiglasi kunye neelensi zokudibanisa njengoko kufuneka.Kusenokunqweneleka ukuvumela abasebenzisi boqhagamshelwano ukuba bathathe ikhefu kubafowunelwa okanye xa bengenako ukunxiba abafowunelwa.
Ukuhlolwa kwamehlo rhoqo kubalulekile kwimpilo yamehlo.I-American Academy of Ophthalmology (AAO) incoma ukuba bonke abantu abadala abaphakathi kweminyaka engama-20 kunye ne-30 bahlolisise umbono wabo rhoqo kwi-5 kwiminyaka eyi-10 ukuba banombono omhle kunye namehlo aphilileyo.Abantu abadala abadala kufuneka babe novavanyo olusisiseko lwamehlo malunga neminyaka engama-40 ubudala, okanye ukuba baneempawu zokungaboni okanye banembali yosapho yobumfama okanye iingxaki zokubona.
Ukuba abantu bafumana nayiphi na kwezi meko zilandelayo, kungakhathaliseki ukuba banayo na ummiselo wangoku, kufuneka babone i-ophthalmologist ukuze bahlolwe:
Ukuhlolwa kwamehlo rhoqo kunokwazi ukubona iimpawu zakwangoko zezinye izifo, ezinjengomhlaza, isifo seswekile, icholesterol ephezulu, nesifo samathambo.
Utyando lwamehlo eLaser lunokuba yindlela esebenzayo nesisigxina yokunxiba iiglasi okanye iilensi zokunxibelelana.Umngcipheko wemiphumo emibi uphantsi, ngokutsho kwe-AAO, kunye neepesenti ze-95 zalabo abaqhuba inkqubo babika iziphumo ezilungileyo.Nangona kunjalo, le nkqubo ayiyena wonke umntu.
I-PIOL yilensi ethambileyo, enwebekayo abathi oogqirha botyando bayifake ngqo kwiliso phakathi kwelensi yendalo kunye ne-iris.Olu nyango lufanelekile kubantu abanemimiselo ephezulu kakhulu ye-astigmatism kunye nezibuko zamehlo.Utyando lweliso lwe-laser olulandelayo lunokuphucula ngakumbi umbono.Ngelixa le inokuba yinkqubo ebiza imali eninzi, ingabizi kakhulu kuneendleko zobomi bonke zokunxiba iindondo okanye iilensi zoqhagamshelwano.
Olu nyango lubandakanya ukunxiba iilensi ezinzima zokudibana ebusuku ukunceda ukubumba kwakhona i-cornea.Lo ngumlinganiselo wesikhashana wokuphucula umbono wosuku olulandelayo ngaphandle koncedo olongezelelweyo kwiilensi okanye iiglasi.Ilungele abantu abane-astigmatism.Nangona kunjalo, ukuba umntu onxibileyo wayeka ukunxiba iilensi ebusuku, zonke izibonelelo zazibuyiselwa umva.
Iiglasi kunye neelensi zoqhagamshelwano zinceda ekuphuculeni umbono, kwaye nganye ineenzuzo kunye neengxaki zayo.Abasebenzisi banokunqwenela ukuthathela ingqalelo uhlahlo lwabiwo-mali, into yokuzonwabisa, kunye nendlela yokuphila ngaphambi kokuba bakhethe phakathi kwabo.Iimpawu ezininzi kunye neenkonzo zibonelela ngezona ndlela zifanelekileyo.
Kungenjalo, izisombululo zotyando olusisigxina ngakumbi njengotyando lwe-laser okanye iilensi ezifakelweyo zinokuqwalaselwa.
Iindleko zeelensi zoqhagamshelwano zixhomekeke kuhlobo lwelensi, ukulungiswa kombono ofunekayo kunye nezinye izinto.Funda ukuze ufumane okungakumbi, kuquka iingcebiso zokhuseleko.
Ii-lens zoqhagamshelwano zemihla ngemihla kunye nenyanga ziyafana, kodwa nganye ineenzuzo kunye neengxaki zayo.
