Lens Vision Lens VS.Bifocal VS.Iterambere
icyerekezo kimwe gitanga icyerekezo kimwe cyo gukosora.Ibi bivuze ko bakwirakwiza intumbero iringaniye hejuru yinzira zose, aho kugabanya intumbero hagati y igice cyo hejuru no hepfo, nkuko bimeze kuri bifocals.Ikirahuri kimwe cyo kureba ni ubwoko bukunze kwandikirwa, kandi burashobora gukosora haba kutareba kure (myopia) cyangwa kureba kure (hyperopia).Niba umuganga wawe atarasobanuye neza imiti yandikiwe, birashoboka ko uzakenera ibirahuri bimwe.Hariho impamvu nyinshi ushobora gukenera icyerekezo kimwe.Abaguzi bamwe bakoresha intumbero imwe yibirahure mubirahuri byabo byo gusoma, bikemerera ishusho isobanutse kandi isobanutse hafi.Abandi bungukirwa no gusobanuka kure, kurugero, mugihe ukoresheje ibirahuri byanditse byerekanwa iyo utwaye.
Bifocals ifasha abakeneye gukosora iyerekwa rya myopiya (kutareba kure) na presbyopiya (kureba kure).Lens yemerera iyerekwa risobanutse kuri intera iri murwego rumwe.
Bashobora gutekerezwa nkibisanzwe byandikirwa hamwe nigice cyo gusoma.Igice cyo gusoma gisanzwe gishyizwe mugice cyo hepfo yinzira
D Seg Bifocals
Agace ko gusoma ka D Seg Bifocal gasa ninyuguti D ihagaze kuruhande rwayo.Bashobora kwitwa Flat Top Bifocal.D Seg nigishushanyo cyoroshye cya Bifocal kumuntu wambara guhuza.Kubera iyi, ni ubwoko buzwi cyane ku isoko muri iki gihe.
Igice cyo gusoma kiraboneka muburyo butandukanye.Lens ikoreshwa cyane ni D 28 na D 35. Igice cya D 28 gifite ubugari bwa 28mm naho D 35 ni 35mm z'ubugari.

Ibice bibiri bivanze
Nubwo ibice bibiri bifitemo imirongo igaragara kumupaka wibice bya lens, hariho uruziga ruvanze-seg bifocal rufite ibintu bitagaragara hafi yicyiciro kuruta mubyara bisanzwe bisanzwe.
Igice cyegeranye cyahujwe mugice cyintera yinzira kuburyo itagaragara.
Nta murongo ugaragara, uruziga ruvanze seg bifocal rutanga isura yubusore kuruta umurongo wa kabiri.
Lens igenda itera imbere ifite ibintu bitatu byanditse mubirahuri.Ibyo biragufasha gukora akazi kegereye (nko gusoma igitabo), akazi ko hagati (nko kugenzura urubuga kuri mudasobwa), cyangwa kureba intera (nko gutwara) udakeneye guhindura ibirahuri byawe.Rimwe na rimwe byitwa lensifike.
Iterambere ryiterambere namakuru agezweho kuri bifocal na trifocal lens.Byombi muburyo busanzwe bwibirahure bifite imirongo yo kuvuga mumurongo.Iterambere rifite isura nziza.Rimwe na rimwe, bitwa "nta murongo wa kabiri," ariko ibyo ntabwo ari byiza.Byarushaho kuba byiza kwita lens igenda itera imbere "nta murongo utagira umurongo."
Hamwe na lens igenda itera imbere, ntuzakenera kugira ibirahuri birenze kimwe hamwe nawe.Ntugomba guhinduranya hagati yo gusoma no kurahure bisanzwe.
Icyerekezo hamwe niterambere kirasa nkibisanzwe.Niba uhinduye ukareba ikintu hafi yikintu kiri kure, ntuzabona "gusimbuka" nkuko wabikora hamwe na bifocals cyangwa trifocals.Niba rero utwaye imodoka, urashobora kureba ku kibaho cyawe, kumuhanda, cyangwa ku kimenyetso kiri kure hamwe ninzibacyuho yoroshye.
