Indorerwamo zizuba zifunga urumuri rutameze neza mugihe urinze amaso yawe imirasire ya UV.Ibi byose birashoboka tubikesha ifu yifu ya filteri "hitamo" urumuri nkuko ikubise.Ibirahuri by'amabara birashobora gutoranya bimwe mubice byumurambararo bigizwe nimirasire yizuba kuko bikoresha ifu nziza yicyuma (icyuma, umuringa, nikel, nibindi).Mubyukuri, iyo urumuri rukubise lens, ruba rushingiye ku nzira yitwa "kwivanga kwangiza."
Nukuvuga ko, mugihe uburebure bwumucyo runaka (muriki gihe, UV-A, UV-B, ndetse rimwe na rimwe na infragre) binyura mumurongo, bahagarika mugenzi wabo imbere mumurongo, werekeza kumaso.Kwuzuzanya kwumucyo wumucyo ntabwo ari impanuka: impinga yumuraba umwe hamwe ninkono yumuraba wegeranye uhagarika undi.
Ikintu cyo kwivanga cyangiza biterwa nigipimo cyo kwangirika kwinzira (ni ukuvuga urwego imirasire yumucyo igenda iyo inyuze mubintu bitandukanye mukirere), kandi biterwa nubunini bwinzira.Muri rusange, umubyimba wintanga ntuhinduka cyane, mugihe indangagaciro yo kwangirika yinzira iratandukanye ukurikije itandukaniro ryimiterere yimiti, kandi indorerwamo zizuba ntizigomba guhura nizuba ryizuba.
