Intumbero imwe: Lens yose ifite imbaraga zimwe zo kwandika.Yashizweho kugirango akosore ikibazo cyerekezo nko kutareba kure cyangwa kureba kure.Ibiranga ingingo imwe yibanze itanga icyerekezo gisobanutse intera runaka (hafi, hagati cyangwa kure).
Lens ya Varifocal: Lens imwe ije mububasha butandukanye bwo kwandikisha kugirango ikosore hafi, hagati, no kureba kure.Ibiranga buhoro buhoro imbaraga zo kwandikirwa kuva hejuru kugeza hepfo ya lens, kwemerera inzibacyuho idafite intera hagati yo kureba kure.Kuberako imbaraga zo kwandikirwa zigenda neza kuva hejuru kugeza hepfo yinzira, nanone bita lens igenda itera imbere.
Niki cyiza cyerekezo kimwe cyangwa byinshi?
Mugihe usuzumye niba icyerekezo kimwe cyangwa lensifike nyinshi ari nziza kuri wewe, hari ibintu byinshi ugomba gusuzuma:
∙Icyerekezo gikenewe: Niba ukeneye gukosora gusa ubwoko bumwe bwicyerekezo (nko kutareba kure cyangwa kureba kure), icyerekezo kimwe ni cyiza.Indorerwamo nyinshi zirakwiriye niba ufite ibibazo byinshi byo kureba cyangwa ukeneye gukosorwa hafi no kureba kure.
∙Icyoroshye: Intumbero imwe yo kureba yorohereza gukora imirimo yihariye, nko gusoma cyangwa gutwara, kuko byateguwe neza intera imwe.Ariko, niba uhinduranya kenshi hagati yimikorere niyerekanwa kure, linzira nyinshi zirashobora gutanga inzibacyuho itandukanijwe hagati yintera zitandukanye.
∙Imibereho: Reba imibereho yawe nibikorwa bya buri munsi.Kurugero, niba umara umwanya munini ukora kuri mudasobwa cyangwa gusoma,indorerwamo nyinshibirashobora kuba byiza cyane kuko birashobora gutanga icyerekezo gisobanutse ahantu hatandukanye utiriwe uhinduranya ibirahuri bitandukanye.
∙Igihe cyo Guhindura: Ni ngombwa kumenya ko abantu bamwe bashobora gukenera igihe cyo guhinduka mugihe bimukiye mumurongo utandukanye, kuko ibi bikubiyemo guhuza ingingo zitandukanye.Intumbero imwe yo kureba mubisanzwe ntabwo ifite iki gihe cyo guhindura.
∙Ubuzima bw'amaso: Ubuzima bw'amaso yawe nibihe byose byihishe bishobora nanone kugira ingaruka kumahitamo yawe yerekana icyerekezo kimwe na lensifocal.Inzobere mu kwita ku jisho zirashobora gutanga ubuyobozi bushingiye kubyo ukeneye byubuzima bwamaso.
Muncamake, guhitamo neza hagati yicyerekezo kimwe nicyerekezo kinini biterwa nicyerekezo cyawe ukeneye, ibikorwa bya buri munsi, nubuzima bwamaso.Ni ngombwa kuganira kuri ibi bintu hamwe ninzobere mu kwita ku jisho kugirango umenye amahitamo meza kuri wewe.
Nigute ushobora kumenya niba l ikeneye icyerekezo kimwe cyangwa lens igenda itera imbere?
Kugirango umenye niba ukeneyeicyerekezo kimwe or lens igenda itera imbere,suzuma ibintu bikurikira hanyuma ubiganireho numwuga wawe wo kwita kumaso:
∙ Presbyopia: Niba urengeje imyaka 40 kandi ufite ikibazo cyo kubona ibintu byegeranye, ushobora kugira presbyopiya.Iterambere ryiterambere rifasha gukemura iki kibazo kijyanye nimyaka mugutanga inzibacyuho iturutse kumyerekano ya kure hejuru kugeza hafi yicyerekezo hepfo.
Vision Iyerekwa ryinshi rikeneye: Niba ufite icyerekezo gitandukanye gikeneye intera, intera ndende, hamwe nicyerekezo cyegereye, nko gusoma, akazi ka mudasobwa, no gutwara, lens igenda itera imbere irashobora gutanga icyerekezo gisobanutse kure cyane bitabaye ngombwa ko uhinduranya ibirahuri byinshi byikirahure.
Estyle Imibereho nibikorwa bya buri munsi: Reba ibikorwa byawe bya buri munsi ninshuro uhindura hagati yimirimo itandukanye igaragara.Niba uhinduranya kenshi hagati yintera nintera yo kureba, lens igenda itera imbere irashobora gutanga ibyoroshye no gukosora icyerekezo.
Health Ubuzima bw'amaso: Bimwe mubuzima bwamaso cyangwa ibibazo byerekezo bishobora kwerekana ko hakenewe ubwoko bwihariye.Muganire kubibazo byose byubuzima bwamaso hamwe ninzobere mu kwita kumaso kugirango umenye amahitamo meza kubyo ukeneye.
∙ Ibyifuzo no guhumurizwa: Abantu bamwe bashobora guhitamo ubworoherane nuburanga bwiza bwiterambere, mugihe abandi bashobora kubona icyerekezo kimwe cyoroshye kubikorwa byihariye.
Ubwanyuma, ikizamini cyuzuye cyamaso hamwe nibiganiro hamwe ninzobere mu kwita ku jisho bizafasha kumenya niba intumbero imwe yo kureba cyangwa intambwe igenda itera imbere ari byiza kubyo ukeneye byo kureba no kubaho.Ukurikije ibyifuzo byawe byihariye, inzobere mu kwita ku jisho irashobora kuguha amahitamo akwiye kuri wewe.
Yego,icyerekezo kimweIrashobora gukosora astigmatism.Astigmatism ni ikosa risanzwe ryangirika riterwa na cornea cyangwa lens idasanzwe idasanzwe mumaso, bigatera kutabona neza cyangwa kugoreka kure.Intumbero imwe yo kureba irashobora gukemura neza astigmatisme yinjizamo imbaraga zikenewe zo gukosora kugirango yishyure kugabanuka kudasanzwe kwa optique yijisho.Mugihe cyo gukosora astigmatisme, lens imwe yicyerekezo irashobora gutegekwa kubisobanuro byihariye bikenewe kugirango ikosore amakosa yangiritse ajyanye nibibazo.Iyi nyandiko igenwa hifashishijwe ikizamini cyuzuye cyamaso cyakozwe ninzobere mu kwita ku jisho, gikubiyemo ibipimo byo gusuzuma urugero n’icyerekezo cya astigmatism muri buri jisho.Icyerekezo kimwe cyerekanwe kugirango gikosore astigmatism mubisanzwe harimo imbaraga za silindrike yongeyeho imbaraga za serefegitura.Imbaraga za cylinder ningirakamaro kugirango habeho impinduka zijyanye no kugabanuka kwa cornea cyangwa lens, kwemeza ko urumuri rwangiritse kandi rwibanze neza kuri retina.Mugushira muburyo bwo gukosora astigmatisme muburyo bwa lens, lens imwe yo kureba irashobora kwishyura neza uburiganya no kugoreka abantu bafite astigmatism.Birakwiye ko tumenya ko icyerekezo kimwe cyerekanwe kuri astigmatism kirahuzagurika kandi gishobora guhuza ibyifuzo bitandukanye, harimo intera, hafi, cyangwa iyerekwa hagati.Byaba bikoreshwa mubirahuri cyangwa guhuza amakuru, izo lens zirakwiriye kubantu bingeri zose bafite astigmatism, bityo bikuzuza ubuzima butandukanye nibisabwa.Niba byateganijwe neza, intumbero imwe ya astigmatism irashobora gutanga ihumure nicyerekezo.Mugukemura ibitagenda neza mumiterere yijisho, izo lens zifasha abantu kunoza ibitekerezo, kugabanya umunaniro wamaso, no kuzamura ubwiza bwamaso muri rusange.Ibi bifasha gutanga uburambe bworoshye kandi bushimishije kubantu bishingikiriza kumurongo umwe wo kureba kugirango bakosore astigmatism.Muncamake, intumbero imwe yicyerekezo irashobora gukosora astigmatism mugushyiramo imiti yabigenewe yitaye kumakosa yihariye yo kwanga ajyanye na astigmatism.Mugutanga ubugororangingo bwihariye, izo lens zagenewe kunoza icyerekezo kubantu bafite astigmatism no kuzamura ireme ryicyerekezo rusange.
