Itandukaniro riri hagati yicyerekezo kimwe na Lifensi: Isesengura ryuzuye

Lens ni ikintu cyingenzi mugukosora iyerekwa kandi biza muburyo butandukanye ukurikije ibyo uwambaye akeneye. Babiri mu bakunze gukoreshwa niicyerekezo kimwenaIbice bibiri. Mugihe byombi bikora kugirango bikosore ubumuga bwo kutabona, byateguwe kubikorwa bitandukanye nabantu. Gusobanukirwa gutandukanya izo lens ni ngombwa muguhitamo neza, cyane cyane ko icyerekezo cyabantu gikeneye guhinduka hamwe nimyaka hamwe nubuzima bwabo. Muri iri sesengura rirambuye, tuzasesengura itandukaniro riri hagati yicyerekezo kimwe ninzira ebyiri, harimo ibyo zikoreshwa, inyungu, nuburyo bakemura ibibazo byihariye byo kureba.

1. Intumbero imwe y'Icyerekezo: Niki?

Icyerekezo kimwe cyerekanwe nuburyo bworoshye kandi bukoreshwa cyane muburyo bwamaso. Nkuko izina ribigaragaza, izo lens zagenewe gukosora icyerekezo ku burebure bumwe. Ibi bivuze ko bafite imbaraga zimwe zo gukosora hejuru yuburinganire bwa lens, bigatuma bikwiranye no gukemura ubwoko bumwe bwikosa ryangiritse - habakutareba kure (myopia)cyangwakureba kure (hyperopiya).

Ibintu by'ingenzi:

• Imbaraga Zimwe: Lens ifite imbaraga zihoraho zo kwandikirwa, yibanda kumucyo kumwanya umwe kuri retina. Ibi bituma habaho icyerekezo gisobanutse intera imwe.
• Imikorere yoroshye: Kuberako icyerekezo kimwe cyerekezo gikosora kubwoko bumwe gusa bwikibazo cyicyerekezo, birasa neza muburyo bwo gukora no gukora.
• Kuri Myopiya (Kureba kure): Abafite ubushishozi bafite ikibazo cyo kubona ibintu bya kure neza. Intumbero imwe yo kureba kure ikora mukwirakwiza urumuri mbere yuko ikubita retina, ifasha ibintu bya kure kugaragara.
• Kuri Hyperopiya (Kureba kure): Abantu bafite ubushishozi barwana no kubona ibintu hafi. Icyerekezo kimwe cyerekezo cya hyperopia yibanda kumucyo cyane kuri retina, ikazamura hafi yicyerekezo.

Koresha Imanza:

Intumbero imwe yo kureba irashobora kandi gukoreshwa kubantu bafite astigmatism, imiterere aho cornea yijisho iba imeze kuburyo budasanzwe, biganisha kumyumvire igoretse kure. Indanganturo imwe yihariye yerekanwetoriczakozwe kugirango zikosore astigmatism.

Ibyiza by'Icyerekezo kimwe:

1. Igishushanyo cyoroshye n'umusaruro: Kuberako izo lens zagenewe gukosora iyerekwa intera imwe gusa, ziroroshye kandi zihenze kubyara kuruta linzira nyinshi.
2. Urwego runini rwa porogaramu: Intumbero imwe yo kureba irahuza kandi irakwiriye kubantu bingeri zose bafite ubwoko bumwe gusa bwikosa.
3. Igiciro cyo hasi: Mubisanzwe, icyerekezo kimwe cyo kureba kirahendutse kuruta ibice bibiri cyangwa bitera imbere.
4. Kumenyera byoroshye: Kuberako lens zose zimeze kimwe mububasha bwayo bwo gukosora, abambara linzira imwe yo kwerekwa bamenyera byoroshye bitabaye ngombwa ko bagoreka cyangwa ngo bagire ikibazo.
5. Urutonde ntarengwa: Icyerekezo kimwe cyerekezo gikosora gusa ubwoko bumwe bwikibazo cyerekezo (hafi cyangwa kure), gishobora kuba kidahagije kubantu barwara presbyopiya cyangwa ibindi bihe bijyanye nimyaka bigira ingaruka kumyerekano yegeranye cyangwa kure.
6. Impinduka z'amaso kenshi: Kubantu bakeneye gukosorwa haba kure ninshingano zegeranye (urugero, gusoma no gutwara), lens imwe yo kureba irashobora gukenera guhinduranya hagati y'ibirahuri bitandukanye, bishobora kutoroha.

2. Lens ya Bifocal: Nibiki?

Ibice bibiri byateguwe kubantu bakeneye gukosorwa byombiicyerekezo cya kurenahafi y'icyerekezo. Izi lens zigabanyijemo ibice bibiri bitandukanye: igice kimwe nukubona ibintu bya kure neza, mugihe ikindi nukubona ibintu byegeranye, nkigihe usoma. Bifocals yari isanzwe ikorwa kugirango ikemurepresbyopia, imiterere aho ijisho ritakaza ubushobozi bwo kwibanda kubintu byegeranye uko abantu basaza.

 Ibintu by'ingenzi:

• Ibyanditswe bibiri muri Lens imwe: Bifocal lens ifite imbaraga ebyiri zitandukanye zo gukosora mumurongo umwe, mubisanzwe utandukanijwe numurongo ugaragara. Igice cyo hejuru cya lens gikoreshwa mukurebera kure, mugihe igice cyo hepfo gikoreshwa mugusoma cyangwa indi mirimo yegeranye.
• Umurongo utandukanya.
• Kuri Presbyopiya: Impamvu zikunze kugaragara abantu bambara lens ya bifocal ni ugukosora presbyopia. Iyi miterere ijyanye n'imyaka mubisanzwe itangira kwibasira abantu bari hagati yimyaka 40 na 50, bikabagora kwibanda kubintu biri hafi, nko gusoma cyangwa gukoresha terefone.
• Kubyerekezo icyarimwe: Bifocals nibyiza kubantu bakeneye guhinduranya kenshi hagati yo kureba ibintu bya kure (nko gutwara cyangwa kureba TV) no gukora imirimo yegeranye (nko gusoma cyangwa gukoresha mudasobwa). Igishushanyo-kimwe-kimwe kibemerera gukora ibi badahinduye ibirahure.

Ibyiza bya Bifocal Lens:

1. Byoroshye Babiri-muri-umwe: Bifocals ikuraho gukenera gutwara ibirahuri byinshi. Muguhuza intera hamwe no gukosora iyerekwa muburyo bumwe, batanga igisubizo gifatika kubafite presbyopiya cyangwa ibindi bakeneye kwibanda cyane.
2. Kunoza imikorere yibikorwa: Kubantu bakeneye icyerekezo gisobanutse haba kure kandi yegeranye, bifocals itanga iterambere ryihuse mumikorere ya buri munsi nta kibazo cyo guhora uhinduranya ibirahure.
3. Igiciro-Cyiza Ugereranije niterambere.
4. Igice kigaragara: Kimwe mubintu bigaragara cyane biranga bifocal lens ni umurongo ugaragara utandukanya uturere tubiri. Abakoresha bamwe basanga ibi muburyo budashimishije, kandi birashobora no gukora ingaruka "gusimbuka" mugihe uhinduranya mubice byombi.
5. Icyerekezo giciriritse: Bitandukanye ninzira zigenda zitera imbere, bifocals ifite uturere tubiri twandikirwa - intera na hafi. Ibi bisiga icyuho cyerekezo cyo hagati, nko kureba ecran ya mudasobwa, ishobora kuba ikibazo kubikorwa bimwe.
6. Igihe cyo Guhindura: Abakoresha bamwe barashobora gufata umwanya kugirango bahindure impinduka zitunguranye hagati ya zone ebyiri yibanze, cyane cyane iyo bahinduye intera hamwe nicyerekezo hafi.

3. Kugereranya birambuye Hagati y'Icyerekezo kimwe na Lifensi ya Bifocal

Kugirango usobanukirwe neza itandukaniro ryingenzi riri hagati yicyerekezo kimwe ninzira ebyiri, reka tugabanye itandukaniro ryabo mubijyanye nigishushanyo, imikorere, nuburambe bwabakoresha.

4. Ni ryari Ukwiye Guhitamo Icyerekezo kimwe cyangwa Bifocal Lens?

Guhitamo hagati yicyerekezo kimwe ninzira zifatika ahanini biterwa nicyerekezo cyawe gikenewe. Hano haribintu bimwe aho buri bwoko bushobora kuba amahitamo meza:

Guhitamo Icyerekezo kimwe:

• Kureba kure cyangwa Kureba kure: Niba ufite ubwoko bumwe gusa bwikosa ryangiritse, nka myopiya cyangwa hyperopiya, kandi ntukeneye gukosorwa haba hafi no kure, icyerekezo kimwe nicyerekezo cyiza.
• Abakiri bato: Abakiri bato muri rusange bakeneye gukosorwa kubwoko bumwe bwikibazo. Kubera ko badakunze guhura na presbyopiya, lens imwe yo kureba itanga igisubizo cyoroshye kandi cyigiciro.
• Imyaka ijyanye na Presbyopiya: Niba ufite ikibazo cyo kwibanda kubintu byegeranye bitewe na presbyopiya ariko ugakenera gukosorwa intera, lens ya bifocal ni amahitamo afatika.
• Guhindura kenshi Hagati Yegereye na kure: Kubantu bakeneye guhinduranya buri gihe hagati yo kureba ibintu bya kure no gusoma cyangwa gukora imirimo yegeranye, lens bifocal itanga ubworoherane nibikorwa mumurongo umwe.

5. Umwanzuro

Muri make, icyerekezo kimwe cyerekanwe hamwe na bifocal lens byashizweho kugirango bihuze ibyifuzo bitandukanye byo gukosora. Intumbero imwe yo kureba iroroshye kandi nziza kubantu bato cyangwa bakeneye gukosora ubwoko bumwe bwikibazo cyerekezo, nko kutareba kure cyangwa kureba kure. Ku rundi ruhande, lensifike ya Bifocal igenewe abantu bakuze bafite presbyopiya bakeneye gukosorwa haba hafi ndetse no kure, bitanga igisubizo cyoroshye-kimwe-kimwe.

Guhitamo linzira iboneye nintambwe yingenzi muburyo bwo kureba neza ubuzima bwiza no guhumurizwa burimunsi. Kugisha inama hamwe na optometriste cyangwa inzobere mu kwita ku jisho birasabwa cyane kumenya ubwoko bwa lens bujyanye nibyo ukeneye kugiti cyawe.
