Nyuma y'imyaka 40, ese byarakugoye gusoma ikinyamakuru cyangwa ubutumwa kuri terefone yawe? Ese wagombaga kwimura ukuboko kwawe gato kubera ko inyuguti zisa n'izijimye? Ibi ni ibintu bibaho ku bantu benshi. Ariko iyo wambaye indorerwamo kugira ngo urebe neza, ugomba kuzikuramo iyo ubonye kure. Guhindura izi ndorerwamo ni ikibazo gikomeye kuri bamwe. None se, wigeze wumva ikoranabuhanga ryitwa 'Monovision' ritanga igisubizo cyiza kuri ibi? Reka tubiganireho uyu munsi.
Mu magambo make, monovision ni iki?
Biroroshye cyane. Monovision ni uburyo bwo gutoza amaso yawe kwibanda ku bintu biri hafi yawe (urugero, gusoma igitabo, kureba telefoni yawe) n'irindi jisho ryawe kwibanda ku bintu biri kure (urugero, gutwara imodoka, kureba televiziyo) . Ni nko guha amaso yawe imirimo ibiri itandukanye.
Tekereza muri ubu buryo. Ijisho rimwe ryawe rishobora kureba hafi, irindi jisho rikabona kure cyane. Ubwonko bwawe buhuza amashusho y'aya maso yombi, bugakora ishusho yuzuye igufasha kubona neza hafi na kure. Hari abantu bayita 'iyerekwa rivanze'. Ibi bivuze ko ushobora gukuraho burundu ikibazo cyo gukoresha indorerwamo kugira ngo urebe hafi.
Kuki dukeneye ikintu nk'iki?
Uko twese tugenda dusaza, ubusanzwe nyuma y'imyaka 40, biragoye kubona ibintu neza. Ushobora kuba warabonye abantu bakuze bakubita amaso mu gihe basoma ikinyamakuru. Mu buvuzi, iyi ndwara tuyita 'presbyopia' .
Ibi biterwa nuko ubushobozi bwo koroshya imboni y'amaso yacu bugabanuka uko imyaka igenda ishira. Imitsi mito iri imbere mu jisho ('imitsi ya siliari') ntishobora kunama iyi lenzi uko bikenewe kugira ngo yibande ku kintu cyegereye. Ibi byitwa 'Accommodation reflex' igabanya intege.
Monovision irinda iyi nzira yo kugabanya imbaraga. Nanone, abantu babazwe ijisho rimwe bashobora gushyirwamo lenzi hifashishijwe iyi monovision.
Ni ubuhe buryo bwo kugera kuri monovision?
Hari uburyo butandukanye ushobora kugera kuri iyi monovision. Bumwe ni ubw'igihe gito, ubundi ni ubw'igihe kirekire.
- Indorerwamo zo mu bwoko bwa contact lenses: Ubu ni bwo buryo bwiza kandi bwizewe bwo kureba niba monovision ikubereye. Muganga wawe azashyira lenti yo kureba hafi mu jisho rimwe n'iyo kureba kure mu jisho rindi igihe gito. Iki ni igihe cyiza cyo kureba niba ushobora kumenyera no kureba niba ufite ikibazo.
- Gukosora Iyerekwa rya Laser: Niba usanze ubu buryo bukora neza hamwe n'indorerwamo z'amaso, LASIK cyangwa PRK bishobora kuba igisubizo kirambye.Ushobora kubagwa hakoreshejwe laser muri ubu buryo. Ibi bihindura imiterere y'ijisho kandi bigatanga monovision ihoraho.
- Kubaga Indorerwamo z'amaso: Mu gihe cyo kubaga indorerwamo z'amaso, indorerwamo y'ubukorano ishyirwa mu jisho ishobora guhindurwa kugira ngo igaragare neza.
Igikuru ni ukugerageza igihe cyose ukoresheje indorerwamo z'amaso kugira ngo urebe uburyo sisitemu ya monovision ikubereye mbere yo kubagwa burundu.
Ni izihe nyungu n'ibibi by'ubu buryo?
Kimwe n'ubundi buryo bwose bwo kuvura, monovision ifite ibyiza n'ibibi. Reka turebe ibyo ari byo.
| Ibyiza | Imbogamizi |
|---|---|
| Kwishingikiriza ku ndorerwamo kugira ngo umuntu arebe hafi biragabanuka cyane. | Hari abantu bigora kumenyera iyi myumvire mishya. Bashobora kumva bazunguze kandi batazi icyo bakora. |
| Ushobora kugerageza indorerwamo z'amaso mbere yo kubagwa burundu. | Kubera ko amaso yombi adakorana, kureba mu buryo bwa 3D no kubona mu buryo bw'ubujyakuzimu bishobora kugabanuka gato. |
| Indorerwamo zo mu bwoko bwa contact lenses zishobora gukoreshwa nk'ubundi buryo ku bantu batinya cyangwa babangamiwe no kubagwa. | Kubona bishobora kuba bitagaragara neza ahantu hatagaragara cyane, cyane cyane nijoro. |
| Imirimo myinshi ya buri munsi ishobora gukorwa nta ndorerwamo. | Hari ikintu kibi cyitwa 'Pulfrich effect' gishobora kubaho. |
Ni iyihe 'ingaruka mbi ya Pulfrich'?
Iki ni ikintu cyo kwitondera. Mu magambo make, kubera ko amashusho ava mu maso yawe ajya mu bwonko asobanutse neza, igihe bifata kugira ngo ubwonko bwawe bukoreshe ayo mashusho yombi kiratandukanye gato. Ishusho y'ijisho rimwe igera mu bwonko bwawe nyuma gato y'isegonda rindi.
Iri tandukaniro rito rituma bidashoboka gusobanukirwa neza intera, umuvuduko, n'icyerekezo cy'ikintu kigenda.
Tekereza utwaye imodoka. Byaba bite bite uramutse udashobora kumenya neza intera iri hagati yawe n'ikinyabiziga cyangwa umuntu wambukiranya umuhanda uri imbere yawe? Iyi ngaruka ishobora kugaragara cyane cyane iyo utwaye imodoka ku muvuduko mwinshi kandi mu rumuri ruto .
Kubwibyo, niba uri umuntu utwara imodoka kenshi, ugomba kubanza kuvugana na muganga wawe mbere yo gufata icyemezo cyo gukoresha monovision.
Ibintu ugomba kuzirikana mu gihe ubana na monovision
Iyo umaze kumenyera monovision, ni ngombwa cyane kwita ku buzima bw'amaso yawe.
- Suzuma amaso yawe buri gihe: Suzuma amaso yawe nibura rimwe mu mwaka cyangwa ibiri, nk'uko byasabwe na muganga w'amaso. Niba ufite izindi ndwara, nka diyabete , ushobora gukenera kuyisuzumisha kenshi.
- Indorerwamo zidasanzwe: Muganga wawe ashobora kukwandikira indorerwamo zidasanzwe zo gukoresha gusa mu gutwara imodoka nijoro cyangwa mu mirimo ikomeye cyane, nko gukora kuri mudasobwa. Ibi bizatuma ubona neza muri ibi bihe by'akaga.
Monovision ni uburyo bwiza bwo gufasha abantu benshi bafite ikibazo cyo kutabona neza kwikuramo indorerwamo. Ariko si ibya buri wese. Niba ushobora kumenyera no kumenya niba bitera ingaruka mbi biratandukanye bitewe n'umuntu ku giti cye.
Ubutumwa bwo kujyana mu rugo
- Monovision ni uburyo bwo gutoza ijisho rimwe kureba hafi n'irindi kureba kure. Ubu ni igisubizo cyiza ku ndwara ya presbyopia ibaho uko umuntu akura.
- Ubu buryo ntibukwiriye buri wese, bityo mbere yo kujya kubagwa burundu, gerageza ukoresheje indorerwamo z'amaso.
- Niba ukunda gutwara imodoka kenshi, vugana na muganga w'amaso ku ngaruka zo kugira 'Pulfrich effect'.
- Indorerwamo yihariye ishobora gukenerwa mu bihe bimwe na bimwe byihariye (nk'iyo gutwara imodoka).
- Ni ngombwa cyane gushaka inama ku muganga w’amaso w’inararibonye kugira ngo uhitemo uburyo bwo kuvura bukubereye.
