Intangiriro

Nkuko izina ribigaragaza, lens ya bifocal ifite lens ebyiri zifotora, lens ya primaire ya kure na lens ya kabiri yegeranye. Ukurikije gukwirakwiza nuburyo bwa sub-lens, igabanijwemo umurongo umwe wumucyo wikubye kabiri, urumuri ruri hejuru yumucyo na dome ebyiri. Lens ya Bifocal irashobora kuzirikana iyerekwa rya kure kandi ryegereye, ariko hariho umurongo ugaragara wo gutandukana, bizareka uwambaye akumva ko hariho gusimbuka, bityo rero nyuma yo kugaragara kwinzira ndende igenda itera imbere, yagiye isimburwa buhoro buhoro. Hano twibanze kumurongo utera imbere.
