Niba ukunda kwambara lens aho guhuza ibirahure kugirango utezimbere icyerekezo cyawe, hari ubwoko bwinshi bwo guhitamo.
Byombi byoroshye kandi byoroshye guhuza lens bifite ibyiza nibibi.Ni ikihe kibereye kuri wewe gishobora guterwa nibyifuzo byawe, imibereho hamwe nibyo ukunda.
Niba utekereza cyane kumurongo woguhuza, soma kugirango umenye ibyiza nibibi byiyi lens nuburyo bwo kuyikoresha neza.
Ubwoko bukoreshwa cyane muburyo bwo guhuza imiyoboro ni gazi ya gaze ya gaze (RGP) .Biraryoshe kandi birinda kwambara kuruta ubwoko bwambere bwambere, nka polymethylmethacrylate (PMMA) gakondo.Icyuma cya PMMA gikoreshwa gake muri iki gihe.
Lens ya RGP ikozwe mubikoresho bya pulasitiki byoroshye bisanzwe birimo silicone. Ibi bikoresho byoroheje bituma ogisijeni inyura mumurongo ugana cornea yijisho ryawe.
Cornea yawe nigice cyimbere cyimbere yijisho ryawe. Cornea yawe yanga urumuri kandi ikora nka lens yo hanze yijisho ryawe.Iyo cornea yawe itabonye ogisijene ihagije, irabyimba. Ibi birashobora gutuma umuntu atabona neza cyangwa atagaragara, kimwe ibindi bibazo byamaso.

LMA ya PMMA ntabwo yemerera ogisijeni kunyura mumurongo. Inzira imwe rukumbi ya ogisijeni ishobora kugera muri cornea nigihe amarira atemba munsi yinzira igihe cyose uhumye.
Kugirango ureke amarira atembera munsi yinzira, lens ya PMMA ni nto cyane mubunini.Ikindi kandi, hagomba kubaho icyuho kiri hagati yinzira na cornea.Ibi bituma lens ya PMMA itoroha kwambara, kandi lens irashobora gusohoka. , cyane cyane iyo ukora siporo.
Kuberako lens ya RGP ituma ogisijeni inyuramo, izo lens nini kuruta PMMA kandi zitwikiriye ijisho ryinshi.
Mubyongeyeho, impande za lens ya RGP zihuza cyane nubuso bwamaso yawe.Ibyo bituma bambara neza kwambara kurusha moderi zishaje.Biremera kandi ko lens ziguma kumaso yawe neza.
Amakosa yangiritse abaho mugihe imiterere yijisho ryawe irinda urumuri rwinjira kutibanda neza kuri retina. Retina ni urwego rwimitsi yoroheje yumucyo inyuma yijisho.
Kwambara lens ya RGP ikomeye irashobora gukosora ubwoko butandukanye bwamakosa yangiritse, harimo:
RGP itumanaho rikomeye ifite ibyiza byinshi kurenza uburyo bworoshye bwo guhuza amakuru. Reka turebe izi nyungu muburyo burambuye:
RGP itajegajega itumanaho nayo ifite ibibi bimwe. Hano hari ibibazo bikunze kugaragara hamwe ninzira.
Niba ushaka ko inzitizi zikomeye zo kumara igihe kirekire gishoboka, ni ngombwa kubyitaho neza.Gufata neza lens yawe birashobora kandi kugabanya ibyago byo kwandura amaso cyangwa kurwara corneal.
Lens ya gaze ya Rigid yemewe (RGP) nubwoko bukunze kugaragara cyane muburyo bwo guhuza amakuru buteganijwe muri iki gihe.Bisanzwe bitanga icyerekezo gityaye, gityaye kuruta icyuma cyoroshye cyo guhuza.Biramara kandi igihe kirekire mugihe kirekire kandi muri rusange ntibihendutse kuruta lens yoroshye.

Na none, ibintu bimwe na bimwe, harimo na astigmatism, birashobora gukosorwa neza hamwe ninzira zikomeye.
Ariko rero, kwambara utuntu duto two guhuza akenshi bifata igihe kirekire kugirango umenyere, kandi ntibishobora kuba byiza nkururondogoro rworoshye. Vugana na muganga wamaso yawe kugirango umenye ubwoko bwi lens bwakubera byiza kandi ukeneye icyerekezo cyawe.
Koga hamwe ninzira zo guhuza bishobora kugufasha kubona neza, ariko bikongera ibyago byo guhura nibibazo bimwe na bimwe bifitanye isano nijisho, kuva ijisho ryumye kugeza bikomeye…
Kugabanuka Kugabanura gutanga ibicuruzwa byinshi, ibiciro biri hasi, kandi byoroshye-gukoresha-urubuga rwo kuyobora.Ni iki kindi uzi hano.
Hano harahantu henshi wagura ibirahuri kumurongo.Bamwe bafite amaduka acururizwamo aho ushobora no guhaha.Abandi bashingira kumyitozo ngororamubiri no murugo.
Niba ushaka kugura umurongo wandikirwa kumurongo, imbuga ziri kururu rutonde zifite amateka ahoraho yo kunezeza abakiriya no gutwara lens nziza nziza…
