Ibisobanuro bigufi:

Bitewe n'ibyo ubuzima bwa none busaba, uruhare rw'indorerwamo zihindura amabara si ukurinda amaso gusa, ahubwo ni n'ubuhanzi. Indorerwamo ebyiri nziza zihindura amabara, hamwe n'imyenda ikwiye, zishobora gupfukirana imiterere idasanzwe y'umuntu. Indorerwamo zihindura amabara zishobora guhinduka bitewe n'ubukana bw'urumuri rwa ultraviolet maze zigahindura ibara ryazo, lensi y'umwimerere ibonerana idafite ibara, ihura n'imirasire ikomeye y'urumuri, izahinduka lensi z'amabara, kugira ngo zikoreshwe mu kurinda amaso, bityo zikwiriye gukoreshwa mu nzu no hanze icyarimwe.

Ikirahuri cy'inyuma cy'umutwe

Ibiranga: Ibyiciro bibiri by'ingenzi mu ma lens abiri, n'ikirahuri gito gishyizwe ku kirahuri gisanzwe; Ku barwayi ba presbyopia bashobora kureba kure na hafi y'aho bahindurira; Hejuru ni urumuri rw'intera (rimwe na rimwe rukaba rugororotse), hasi ni urumuri rw'ishusho; Intera y'intera yitwa urumuri rwo hejuru, hafi yitwa urumuri rwo hasi, itandukaniro riri hagati y'urumuri rwo hejuru n'urwo hasi ni ukongeraho (urumuri rwo hanze);

Ibyiza: Abarwayi ba presbyopia ntibagomba guhindura indorerwamo iyo bareba hafi na kure.

Intangiriro y'umusaruro

Nk'uko izina ribigaragaza, lensi ya bifocal ifite lensi ebyiri za fotometrike, lensi ya far primary na lensi ya near secondary. Dukurikije uko lensi ikwirakwira n'imiterere yayo, igabanyijemo urumuri rw'umurongo umwe, urumuri rw'ibice bibiri rwo hejuru rugororotse n'urumuri rw'ibice bibiri. Lensi ya bifocal ishobora kwita ku kureba kure n'ukubona hafi, ariko hari umurongo usobanutse wo gutandukanya, bizatuma uwambaye yumva ameze nk'aho ariho asimbuka, bityo nyuma yo kugaragara kwa lensi ya progressive multifocal, yagiye isimburwa buhoro buhoro. Aha twibanda ku lensi za progressive multifocal.
