Indorerwamo z'amaso ziza muburyo butandukanye.Ibi birimo intumbero imwe-imwe ifite imbaraga cyangwa imbaraga hejuru yinzira zose, cyangwa lens ya bifocal cyangwa trifocal ifite imbaraga nyinshi hejuru yinzira zose.
Ariko mugihe bibiri byanyuma ari amahitamo niba ukeneye imbaraga zinyuranye mumurongo wawe kugirango ubone kure kandi hafi yibintu, lens nyinshi nyinshi zashizweho numurongo ugaragara utandukanya uturere twandikirwa.
Niba ukunda umurongo utari umurongo wa lisansi kuri wewe cyangwa umwana wawe, intambwe yinyongera igenda ishobora kuba amahitamo.
Ibice bigezweho bigenda bitera imbere, kurundi ruhande, bifite igipimo cyiza kandi gihoraho hagati yububasha butandukanye.Ni muri urwo rwego, barashobora kandi kwitwa "lensifocal" cyangwa "varifocal" lens, kubera ko zitanga ibyiza byose byinzira zishaje za bi- cyangwa trifocal zidafite ibibazo nibibi byo kwisiga.
Inyungu za Lens Iterambere
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" nka
wifuza hamwe na bifocals cyangwa trifocals.Niba rero utwaye imodoka, urashobora kureba ku kibaho cyawe, kumuhanda, cyangwa ku kimenyetso kiri kure hamwe ninzibacyuho yoroshye.
Basa nkibirahuri bisanzwe.Mu bushakashatsi bumwe, abantu bambaye bifocals gakondo bahawe lensike igenda itera imbere kugirango bagerageze.Umwanditsi w’ubushakashatsi yavuze ko benshi bakoze ibintu byiza.
Niba uha agaciro ubuziranenge, imikorere no guhanga udushya wageze ahantu heza.
