Biba bigoye kwibanda ku bintu byegereye. Iyi ndwara yitwa presbyopia. Ishobora gucungwa cyane hakoreshejwe bifocals.
Indorerwamo z'indorerwamo zo mu bwoko bwa Bifocal (zishobora kandi kwitwa Multifocal) zirimo imbaraga ebyiri cyangwa nyinshi zo kugufasha kubona ibintu mu ntera iyo ari yo yose nyuma yo gutakaza ubushobozi bwo guhindura uko amaso yawe areba bitewe n'imyaka.
Igice cyo hasi cya lensi y'ibice bibiri kirimo igice cyo hafi cyo gusoma no gukora indi mirimo yo hafi. Igice gisigaye cya lensi akenshi ni ugukosora intera, ariko rimwe na rimwe nta gikosorwa na kimwe kiba kirimo, niba ufite ubushobozi bwo kureba kure.

Indorerwamo y'ibice bibiri ikora ite?
Indorerwamo za Bifocal ni nziza ku bantu barwaye presbyopia - indwara umuntu agira ikibazo cyo kutabona neza cyangwa kugorama hafi y'aho asoma igitabo. Kugira ngo hakosorwe iki kibazo cyo kureba kure n'aho hafi, indorerwamo za Bifocal zikoreshwa. Zifite ibice bibiri bitandukanye byo gukosora amaso, bitandukanye n'umurongo unyura kuri iyo ndorerwamo. Igice cyo hejuru cya lens gikoreshwa mu kureba ibintu biri kure mu gihe igice cyo hasi gikosora aho kureba hafi.
IBINTU BY'IBIKORESHO BYACU BY'IBIJYANYE
1. Indorerwamo imwe ifite impande ebyiri zo kwibandaho, ntukeneye guhindura indorerwamo iyo ureba kure na hafi.
