Emva kokuba uneminyaka engama-40 ubudala, ngaba kuye kwaba nzima kancinci kuwe ukufunda iphephandaba okanye umyalezo kwifowuni yakho? Ngaba kuye kwafuneka uhambise isandla sakho kude kancinci kuba oonobumba babonakala bengacacanga? Le yinto eyenzekayo kubantu abaninzi. Kodwa xa unxiba iiglasi ukuze ubone kufutshane, kufuneka uzikhulule xa ubona kude. Ukutshintsha ezi glasi kuyingxaki enkulu kwabanye abantu. Ngoko ke, ngaba ukhe weva ngetekhnoloji ebizwa ngokuba yi-'Monovision' eza njengesisombululo esihle koku? Makhe sithethe ngayo namhlanje.
Ngamafutshane, yintoni i-monovision?
Kulula kakhulu. I-Monovision yindlela yokuqeqesha amehlo akho ukuba agxile kwizinto ezikufutshane nawe (umz., ukufunda incwadi, ukujonga ifowuni yakho) kunye nelinye iliso lakho ukuba ligxile kwizinto ezikude (umz., ukuqhuba, ukubukela iTV) . Kufana nokunika amehlo akho imisebenzi emibini eyahlukileyo.
Cinga ngale ndlela. Elinye lamehlo akho likwazi ukubona kufutshane, kwaye elinye iliso likwazi ukubona kude. Ingqondo yakho ngandlela thile idibanisa imifanekiso evela kula mehlo mabini, idala umfanekiso opheleleyo okuvumela ukuba ubone kufutshane nakude ngokucacileyo. Abanye abantu bakubiza oku ngokuthi 'umbono odibeneyo'. Oku kuthetha ukuba ungasusa ngokupheleleyo isidingo seeglasi ukuze ubone kufutshane.
Kutheni sifuna into efana nale?
Njengoko sonke sikhula, ngesiqhelo emva kweminyaka engama-40, kuba nzima ukubona izinto kufutshane. Mhlawumbi ukhe wababona abantu abadala bencwina amehlo ngelixa befunda iphephandaba. Kwezonyango, esi simo sisibiza ngokuba yi-'presbyopia' .
Oku kungenxa yokuba ukuguquguquka kwelensi ngaphakathi kwamehlo ethu kuncipha xa sele kukhulile. Izihlunu ezincinci ngaphakathi kweliso ('izihlunu zeciliary') azikwazi ukugoba le lensi njengoko kufuneka ukuze zigxile kwinto esondeleyo. Oku kubizwa ngokuba yi -'Accommodation reflex' ebuthathaka.
I-Monovision iyayiphepha le nkqubo ibuthathaka. Kwakhona, abantu abenza utyando lwe-cataract kwelinye iliso ngamanye amaxesha banokufakelwa ilensi kunye nale nkqubo ye-monovision.
Ziziphi iindlela zokufezekisa i-monovision?
Kukho iindlela ezahlukeneyo onokufikelela kuzo kule monovision. Ezinye zezexeshana, ezinye zihlala zihleli.
- Iilensi zoQhagamshelwano: Le yeyona ndlela ilungileyo nekhuselekileyo yokubona ukuba i-monovision ikulungele na. Ugqirha wakho uza kubeka ilensi yokujonga okukufutshane kwelinye iliso kunye nelensi yokujonga okukude kwelinye iliso okwethutyana. Eli lixesha elifanelekileyo lokubona ukuba ungaqhelana nayo na kwaye ukuba unayo nayiphi na ingxaki.
- Ukulungiswa koMbono ngeLaser: Ukuba ufumanisa ukuba le ndlela iyasebenza ngee-contact lenses, i-LASIK okanye i-PRK inokuba sisisombululo esihlala sihleli.Ungatyandwa nge-laser ngolu hlobo. Oku kutshintsha imo ye-cornea yeliso kwaye kunike i-monovision engunaphakade.
- Utyando lweLensi ye-Intraocular: Ngexesha lotyando lwe-cataract, ilensi yokwenziwa efakwe ngaphakathi kweliso inokulungiswa kwi-monovision.
Eyona nto ibalulekileyo kukuhlala uzama ixesha lokuvavanya ngee-contact lenses ukuze ubone ukuba inkqubo ye-monovision ikulungele kangakanani na ngaphambi kokuba wenze naluphi na utyando olusisigxina.
Ziziphi iingenelo kunye neengxaki zale ndlela?
Njengalo naluphi na unyango lwezonyango, i-monovision ineengenelo kunye neengxaki. Makhe sijonge ukuba ziyintoni na.
| Iingenelo | Iingxaki |
|---|---|
| Ukuxhomekeka kwiiglasi ukuze ubone kufutshane kunciphile kakhulu. | Abanye abantu banengxaki yokuziqhelanisa nale ndlela intsha yokucinga. Basenokuziva benesiyezi kwaye bedidekile. |
| Ungazama iilensi zokunxibelelana ngaphambi kokuba utyando olusisigxina. | Ngenxa yokuba omabini amehlo awasebenzi kunye, umbono we-3D kunye nokuqonda ubunzulu kunokuncipha kancinci. |
| Iilensi zoqhagamshelwano zingasetyenziswa njengenye indlela kwabo bayoyikayo okanye abangakhululekanga ngotyando. | Umbono unokuba lufiphale kancinci kwiindawo ezinokukhanya okuphantsi, ingakumbi ebusuku. |
| Imisebenzi emininzi yemihla ngemihla ingenziwa ngaphandle kweeglasi. | Imeko eyingozi ebizwa ngokuba yi-'Pulfrich effect' inokwenzeka. |
Yintoni le 'Pulfrich Effect' iyingozi?
Le yinto ekufuneka uyilumkele. Ngamafutshane, kuba ukucaca kwemifanekiso esuka emehlweni akho iye engqondweni yakho kwahlukile, ixesha elithathayo ukuba ingqondo yakho icwangcise le mifanekiso mibini lahlukile kancinci. Umfanekiso ovela kwelinye iliso ufika engqondweni yakho emva kwemizuzwana embalwa kakhulu kunelinye.
Lo mahluko mncinci wenza kube nzima ukuqonda ngokuchanekileyo umgama, isantya, kunye necala lento ehambayo.
Khawucinge ukuba uqhuba imoto. Ingaba ingaba yingozi kangakanani ukuba awukwazi ukwahlula ngokuchanekileyo umgama phakathi kwakho nesithuthi okanye umntu owela indlela phambi kwakho? Esi siphumo sinokubonakala ngakumbi xa uqhuba ngesantya esiphezulu kwaye ekukhanyeni okuphantsi .
Ngoko ke, ukuba ungumntu oqhuba rhoqo, ngokuqinisekileyo kufuneka uthethe nogqirha wakho ngale nto ngaphambi kokuba uthathe isigqibo sokuba uza kuqhuba imoto ende.
Izinto ekufuneka uziqwalasele xa uhlala ne-monovision
Wakuba uqhele i-monovision, kubaluleke kakhulu ukunyamekela impilo yamehlo akho.
- Fumana uhlolo lwamehlo rhoqo: Hlola amehlo akho ubuncinane kanye ngonyaka okanye emibini, njengoko kucetyisiwe ngugqirha wakho wamehlo. Ukuba unezinye izifo, ezifana nesifo seswekile , unokufuna ukuhlolwa rhoqo.
- Iiglasi ezikhethekileyo: Ugqirha wakho angakunika iiglasi ezikhethekileyo onokuthi uzisebenzisele ukuqhuba ebusuku kuphela okanye kwimisebenzi ebuthathaka kakhulu, njengokusebenza kwikhompyutha. Oku kuya kuqinisekisa ukuba unombono ongcono kwezi meko zinobungozi.
I-Monovision yindlela entle yokunceda abantu abaninzi abangaboni kakuhle ukuba balahle iiglasi. Kodwa ayilungelanga wonke umntu. Nokuba ungaqhela na kwaye ingabangela iziphumo ebezingalindelekanga ziyahluka kumntu nomntu.
Umyalezo Wokuya Ekhaya
- I-Monovision yindlela yokuqeqesha iliso elinye ukuba libone kufutshane nelinye ukuba libone kude. Le yisisombululo esilungileyo kwimeko ye-presbyopia eyenzeka xa umntu ekhula.
- Le ndlela ayifanelekanga kuye wonke umntu, ngoko ke ngaphambi kokuba uye kutyando olusisigxina, qiniseka ukuba uyizame ngee-contact lenses.
- Ukuba uqhuba rhoqo, thetha nogqirha wakho wamehlo malunga nomngcipheko we-'Pulfrich effect'.
- Kusenokufuneka isipili esahlukileyo kwiimeko ezithile ezikhethekileyo (ezifana nokuqhuba).
- Kubaluleke kakhulu ukufuna iingcebiso kugqirha wamehlo onamava ukuze ukhethe indlela yonyango efanelekileyo kuwe.
