Itandukaniro riri hagati yicyerekezo kimwe na bifocal lens: Isesengura ryuzuye

Lens ni ikintu cyingenzi mu iyerekwa cyo gukosora no kuza muburyo butandukanye bitewe nibyo ukeneye cyane. Ibirindiro bibiri byakoreshejwe cyane nilens imwenalens. Mugihe bombi bakorera kugirango bahuze ubumuga bugaragara, bagenewe intego zitandukanye. Gusobanukirwa itandukaniro riri hagati yiyi lens ningirakamaro muguhitamo neza, cyane cyane iyerekwa ryabantu rikeneye guhinduka hamwe nubuzima nubuzima. Muri iki gisesengura kirambuye, tuzasesengura itandukaniro riri hagati yicyerekezo kimwe na bifocal lens, harimo no gusaba, inyungu, nuburyo bakemura ibibazo byihariye.

1. Lesion imwe yemewe: Niki?

Lens imwe yo kureba ni ubwoko bworoshye kandi bukoreshwa cyane bwa lens mumaso y'amaso. Nkuko izina ryerekana, iyi lens yagenewe gukosora icyerekezo kuburebure bumwe. Ibi bivuze ko bafite imbaraga zimwe zo gukosora hejuru yimyenda yose, bigatuma bakusanya ubwoko bumwe bwikosa-habaKureba (Myopia)cyangwakurega (Hyperopia).

Ibyingenzi:

• Imbaraga imwe: Lens ifite imbaraga zifatika zo kwandikirwa, kwibanda kumucyo mugihe kimwe kuri retina. Ibi bituma habaho icyerekezo gisobanutse kuri intera imwe.
• Imikorere yoroshye: Kuberako lens imwe kugirango ukosore ikintu kimwe gusa cyicyerekezo gusa, birasobanutse neza muburyo no gukora.
• Kurinopia (kutareba): Abafite amahirwe bafite ikibazo cyo kubona ibintu bya kure. Lens Lews imwe yo kurengera neza no gutatanya urumuri mbere yuko ikubita retina, ifasha ibintu bya kure bigaragara ko bikarishye.
• Kuri hyperopia (kurema neza): Abantu bareba kurega kubona ibintu byegeranye. Lens imwe yo kureba kuri Hyperopia yibanze cyane kuri retina, kuzamura hafi yegeranye.

Koresha Imanza:

Lensre lens imwe irashobora kandi gukoreshwa kubantu bafite astigmatism, imiterere aho cornea yijisho ari iy'ijisho ryihariye, biganisha ku iyerekwa rigoretse intera yose. Lens idasanzwe yo kurebainzira ya tocicByakozwe gukosora Astigmatism.

Ibyiza byicyerekezo kimwe cya Vision:

1. Igishushanyo mbonera no gukora: Kuberako iyi lens yagenewe gukosora icyerekezo nkintera imwe gusa, biroroshye kandi bihenze kubyara kuruta lens nyinshi.
2. Intera nini ya porogaramu: Lens imwe yerekwa ni itandukanye kandi ibereye kubantu bafite imyaka yose bafite ubwoko bumwe bwo kumvikana.
3. Igiciro gito: Mubisanzwe, lens imwe yerejwe iraryohewe kuruta lens ya bifocal cyangwa gutera imbere.
4. Guhuza n'imihindagurikire y'ikirere: Kuberako lens yose igeze mu mbaraga zikosowe, abatwara ibinyabuzima rimwe bihuza byoroshye batagoreka cyangwa kutamererwa neza.
5. INGINGO ZIMWE: Lens imwe yo kureba neza gukosora ubwoko bumwe bwicyerekezo kimwe cya Vision (hafi cyangwa kure), ishobora kuba idahagije kubantu batera imbere ibihe byateganijwe mbere na EREVA imyaka.
6. Impinduka zamaso: Kubantu bakeneye gukosorwa kubwintambwe no gufunga hafi (urugero, gusoma no gutwara), lens lens irashobora gukenera guhinduranya ibirahuri bitandukanye, bishobora kutoroherwa.

2. Lens: Niki?

Lens Lens yagenewe abantu bakeneye gukosorwa byombiInteranaHafi y'Icyerekezo. Iyi lens igabanijwemo ibice bibiri byihariye: igice kimwe ni ukubona ibintu bya kure, mugihe undi ari ukubera ibintu bya hafi, nko gusoma. Bifocals yari isanzwe yaremyePresbyopia, imiterere aho ijisho ryatakaje ubushobozi bwo kwibanda kubintu bya hafi nkabantu.

 Ibyingenzi:

• Ibipimo bibiri muri lens imwe: Lenses ya Bifocal ifite imbaraga ebyiri zitandukanye muri lens imwe, mubisanzwe zitandukanijwe numurongo ugaragara. Igice cyo hejuru cya lens gikoreshwa mubyerekezo bya kure, mugihe igice cyo hepfo gikoreshwa mugusoma cyangwa ikindi gikorwa kiri hafi.
• Umurongo utandukanya: Ibihimbaro gakondo bifite umurongo cyangwa umurongo utandukanya ahantu habiri herekwa, bigatuma byoroshye guhinduranya intera no gusoma inyandiko mugukora gusa amaso hejuru cyangwa hepfo.
• Kuri preskyopia: Impamvu nyamukuru abantu bambara lens lens ni ugukosora presbyopia. Iyi miterere ijyanye nubusanzwe itangira kugira ingaruka kubantu muri 40 na 50s, bikabagora kwibanda kubintu byegeranye, nko gusoma cyangwa gukoresha terefone.
• Kubireba icyarimwe gukosorwa: Bifcocals nibyiza kubantu bakeneye guhindura kenshi ibintu bya kure (nko gutwara cyangwa kureba TV) no gukora imirimo yegeranye (nko gusoma cyangwa gukoresha mudasobwa). Igishushanyo cya kabiri-kimwe kibafasha gukora ibi ntabirahure.

Ibyiza bya Bifical Lens:

1. Byoroshye-kimwe-kimwe: Bifocals ikuraho icyifuzo cyo gutwara ibirahuri byinshi. Muguhuza intera no hafi yegereye icyerekezo kimwe, batanga igisubizo gifatika kubantu bafite presbyopia cyangwa ibindi bikenewe.
2. Kunoza imikorere yerekana: Kuberako abantu bakeneye icyerekezo gisobanutse kuri kure no gufunga intera, bifocals batanga iterambere ryihuse mubikorwa bya buri munsi badafite ikibazo cyo guhora uhindukirira ibirahure.
3. Igiciro cyagenwe ugereranije no gutera imbere: Mugihe lens lens zihenze kuruta lens imwe, muri rusange bahendutse kuruta lens igenda itera imbere, itanga inzitizi yoroshye hagati ya zone zitandukanye.
4. Gutandukanya: Kimwe mu bintu bigaragara cyane bya lens lens ni umurongo ugaragara utandukanya uturere twose. Abakoresha bamwe basanga ibi bidashimishije, kandi birashobora kandi gukora ingaruka "gusimbuka" mugihe cyo guhinduranya hagati yibice byombi.
5. Icyerekezo ntarengwa cyo hagati: Ibihugu bitandukanye, bifcanal bifite uturere ebyiri gusa-intera no hafi. Ibi bisiga icyuho cyicyerekezo cyo hagati, nko kureba ecran ya mudasobwa, bishobora kuba ikibazo kubikorwa runaka.
6. Igihe cyo Guhindura: Abakoresha bamwe barashobora gufata igihe cyo kumenyera impinduka zitunguranye hagati ya zone zombi yibanze, cyane cyane iyo zifunguye intera no hafi ya Vision kenshi.

3. Kugereranya birambuye hagati yicyerekezo kimwe na bifocal lens

Kugira ngo wumve neza itandukaniro ryigishushanyo hagati yicyerekezo kimwe hamwe na bifocal lens, reka dusenye itandukaniro ryabo muburyo bwo gushushanya, imikorere, nuburambe bwabakoresha.

4. Ni ryari ugomba guhitamo icyerekezo kimwe cyangwa lens zipikoCal?

Guhitamo hagati yicyerekezo kimwe na lens lens ahanini biterwa nibikenewe byawe. Hano hari ibintu bimwe na bimwe aho buri bwoko bushobora kuba amahitamo meza:

Guhitamo lens imwe:

• Abantu baremewe cyangwa bareba kure: Niba ufite ubwoko bumwe gusa bwo kurohama, nka myopia cyangwa hyperopiya, kandi ntukeneye gukosorwa kwiyemeza hafi ndetse na kure
• Abantu bato: Abantu bakiri bato mubisanzwe bakeneye gukosorwa gusa kubibazo bimwe bya cyerekezo. Kubera ko badashobora guhura na presbyopia, lens Lens Lens itanga igisubizo cyoroshye kandi cyikiciro.
• Imyaka ijyanye na preskyopia: Niba ufite ikibazo cyo kwibanda kubintu hafi kubera amashuri atari yo ariko aracyakeneye gukosorwa kure, lens lens ni amahitamo afatika.
• Guhinduka kenshi hagati yicyerekezo cya kure: Kubantu bakeneye kwimura buri gihe hagati yo kureba ibintu bya kure no gusoma cyangwa gukora imirimo yegeranye, lens lens itaruye byoroshye.

Guhitamo lens ya Bifocal:

5. Umwanzuro

Muri make, lens lens hamwe na bifocal lens yateguwe kugirango ihuze ibikenewe bitandukanye. Lens imwe yo kureba iraryoroshye kandi nziza kubasore cyangwa abakeneye gukosora ikibazo kimwe cyicyerekezo kimwe cyicyerekezo, nko kutareba kure cyangwa kurega. Ku rundi ruhande, inamike, kurundi ruhande, zijyanye n'abantu bakuze hamwe na Presbyopiya isaba gukosorwa haba hafi ndetse no kure yemewe, gutanga igisubizo cyoroshye-kimwe.

Guhitamo lens iburyo nintambwe yingenzi muguharanira ubuzima bwiza no guhumurizwa bwa buri munsi. Kugisha inama hamwe na optometrist cyangwa umwuga w'amaso birasabwa cyane kumenya ubwoko bwa lenses ihuye neza nibyo ukeneye kugiti cyawe.
