Ngaba nawe ukufumene kunzima ukufunda iphephandaba okanye incwadi emva kokuba uneminyaka engama-40 ubudala? Ngaba kufuneka wolule ingalo yakho uze ujonge kude ukuze ubone umyalezo kwifowuni yakho? La mava aqhelekile kubantu abaninzi njengoko bekhula. Okanye ngaba ungumntu olinde utyando lwe-cataract? Emva koko eli bali liza kuba libaluleke kakhulu kuwe. Namhlanje sithetha ngendlela emangalisayo enokusombulula ingxaki yokungaboni kakuhle kwaye inciphise ukusetyenziswa kweeglasi. Yiyo leyo iMonovision.
Ngamafutshane, yintoni iMonovision?
I-Monovision yindlela yokulungisa umbono. Cinga ngayo ngathi amehlo akho enza umsebenzi omncinci. Kule ndlela, elinye lamehlo akho lisetyenziselwa ukubona izinto ezikufutshane (umzekelo, ukufunda incwadi, ukujonga ifowuni yakho) ngokucacileyo . Elinye iliso lisetyenziselwa ukubona izinto ezikude (umzekelo, ibhasi endleleni, uphawu olukude) .
Ngoku usenokuba ucinga, "Ndingabona njani ngokucacileyo?" Kulapho ingqondo yethu ingena khona. Ingqondo yakho ekrelekrele idibanisa imifanekiso evela emehlweni omabini ukuze yenze umfanekiso opheleleyo, ocacileyo okuvumela ukuba ubone kufutshane nakude. Abanye abantu bakubiza oku ngokuthi "umbono odibeneyo."
Kutheni sifuna iMonovision?
Ngokwesiqhelo, xa sijonga into ekufutshane nathi, imo yelensi engaphakathi kweliso lethu iyatshintsha ukuze icace. Oku kwenziwa zizihlunu zeciliary ezingaphakathi kweliso. Oku sikubiza ngokuba yi-accommodation reflex.
Kodwa njengoko sikhula, ingakumbi emva kweminyaka engama-40-45 ubudala, ukuguquguquka kwelensi yethu kuyehla kancinci kancinci. Emva koko, nokuba loo mihlunu izama kangakanani na, ayinakuyitshintsha imilo yelensi ngokwaneleyo ukuba ibone kufutshane. Yiyo loo nto siyibiza ngokuba yi -presbyopia . NgesiGrike, lithetha "amehlo amadala." Yiyo loo nto abantu abadala abaninzi befunda iphephandaba belule iingalo zabo baze bajonge kude.
I-Presbyopia ayisosifo, kodwa yimeko yendalo eyenzeka xa umntu ekhula. I-Monovision sisisombululo esilungileyo koku.
Kwakhona, nokuba une-cataracts kwaye utyando lweliso elinye, ungafakelwa ilensi yangaphakathi kweso (IOL) esweni lakho ngexesha lotyando, eyenzelwe i-monovision. Ungaxoxa ngale nto nogqirha wakho wamehlo uze wenze isigqibo esithe kratya.
Ziziphi iindlela zokufezekisa i-monovision?
Kukho iindlela ezahlukeneyo zokufezekisa i-monovision. Ezinye zezexeshana, oko kuthetha ukuba ungabuyela kwi-normal vision nangaliphi na ixesha. Ezinye zizisombululo ezihlala zihleli.
1. Iilensi zoQhagamshelwano:Le yindlela elula nethandwa kakhulu. Ugqirha wakho uza kukunika iilensi ezimbini ezinamandla ahlukeneyo kwiliso ngalinye. Enye yokujonga kufutshane nenye yokujonga kude. Enye yezona nzuzo zinkulu zale ndlela kukuba "ungazama" (uvavanyo) ngaphambi kokuba uye kutyando olusisigxina. Le yindlela entle yokubona ukuba ungaqhelana nayo na.
2. Ukulungiswa koMbono ngeLaser: Utyando lweLaser olufana neLASIK (Laser-Assisted In Situ Keratomileusis) okanye iPRK (Photorefractive Keratectomy) lunokutshintsha ngokusisigxina imo ye-cornea kwaye lufezekise i-monovision. Ekubeni esi sisisombululo esihlala sihleli, kudla ngokwenziwa kuphela emva kovavanyo ngee-contact lenses ukuqinisekisa ukuba le ndlela ifanelekile kuwe.
3. Utyando lweLensi ye-Intraocular: Njengakwityando le-cataract, kwezinye iimeko, ilensi ekhethekileyo yokwenziwa (Intraocular Lens) inokufakelwa esweni ukuze inike i-monovision.

Makhe sithethe kancinci malunga neengxaki ze-monovision.
Ubunzima bokuqhelana nengqondo
Le yeyona ngxaki iphambili. Kwabanye, ingqondo iyaqhelana nalo mbono mtsha kwiintsuku ezimbalwa. Kwabanye, kungathatha iiveki. Inani elincinci kakhulu labantu lisenokungakwazi ukuziqhelanisa konke konke. Basenokuziva benesiyezi baze balahlekelwe yibhalansi yabo. Yiyo loo nto oogqirha becebisa ukuba uzame ukunxiba iilensi zoqhagamshelwano ngaphambi kotyando olusisigxina.
Ubunzulu obunciphileyo kunye nombono we-3D (Umbono woBunzulu)
Amehlo ethu asebenzisana ukubona ubunzulu bento, okanye i-3D. Kwi-monovision, kuba elinye iliso lijonge kufutshane kwaye elinye likude, le mbono ye-3D iyancipha kancinci. Ke ngoko, kufuneka ulumke kancinci ekuqaleni xa usehla izinyuko okanye upaka imoto.
Le nto eyaziwa ngokuba yiPulfrich effect
Kunzima kancinci, kodwa kulula. Khawuthelekelele ukuba ulwazi lomfanekiso oluvela kwelinye lamehlo akho luthunyelwa engqondweni yakho emva kwexesha elincinci kunolwazi oluvela kwelinye iliso. Oku kunokwenzeka kuba elinye iliso licacile kwaye elinye lifiphele kancinci. Emva koko, xa ujonga into ehamba ngesantya esiphezulu (umz. imoto endleleni, ibhola ephosiweyo), kuba nzima engqondweni yakho ukumisela ngokuchanekileyo umgama wayo kunye necala lokuhamba. Oku sikubiza ngokuba yi-`(isiphumo sePulfrich)`.
Le "Pulfrich effect" inokubangela iimpazamo ekugwebeni umgama, ingakumbi xa uqhuba ebusuku okanye ekukhanyeni okuphantsi. Ke ngoko, kubaluleke kakhulu ukuthetha ngokukhululekileyo nogqirha wakho wamehlo malunga nomsebenzi wakho kunye nemikhwa yemihla ngemihla (ingakumbi ukuqhuba) ngaphambi kokuba uthathe isigqibo sokuba uza kuqhuba nge-monovision.
Izinto ekufuneka uziqwalasele xa uhlala ne-monovision
Ukuba ungumsebenzisi weMonovision, kubalulekile ukuba uhlolwe amehlo akho rhoqo njengoko ugqirha wakho ekucebisa. Ngokuqhelekileyo kufuneka uhlolwe amehlo ubuncinane kanye ngonyaka okanye emibini. Ukuba unezinye izifo, ezifana nesifo seswekile, unokufuna ukuba uhlolwe amehlo akho rhoqo.
Ngamanye amaxesha, ukuba uziva ungakhululekanga kwiimeko ezithile, ezinje ngokuqhuba imoto, ungafumana iiglasi ezikhethekileyo onokuzinxiba ngaloo maxesha kuphela. Konke oku kufuneka kugqitywe ngokubonisana nogqirha wakho, ngokusekelwe kwiimfuno zakho nendlela ophila ngayo.
Umyalezo Wokuya Ekhaya
- I-Monovision sisisombululo esilungileyo kwi-presbyopia, imeko ebangela ukuba ukubona okukufutshane kunciphe njengoko abantu bekhula.
- Apha, iliso elinye lilungiselelwa ukubona kufutshane nelinye ukubona umgama, kwaye ingqondo idibanisa le mifanekiso mibini ukuze ibone ngokucacileyo.
- I-Monovision inokufezekiswa ngokusebenzisa iilensi zoqhagamshelwano, utyando lwelaser (LASIK), okanye ukufakwa kwelensi yokwenziwa.
- Ngaphambi kokuba wenze utyando olusisigxina, qiniseka ukuba uzama iilensi zokunxibelelana kwaye uqiniseke ukuba zikulungele.
- Njengoko kusenokubakho iziphumo ebezingalindelekanga ezincinci ezifana nokuncipha kombono we-3D, kungcono ukuxoxa ngemisebenzi efana nokuqhuba imoto nogqirha wamehlo ukuze wenze isigqibo esifanelekileyo.
