Iyo uguze umutaka, abaguzi bazajya bafungura umutaka kugira ngo barebe niba imbere hari "kole y'ifeza". Muri rusange, duhora dutekereza ko "kole y'ifeza" ingana na "anti-UV". Ese koko izarwanya UV?
None, mubyukuri "kashe ya silver" ni iki?
Kole y'ifeza ni urwego, rukoreshwa cyane cyane mu gutwikira, ntabwo rurwanya imirasire ya UV
Ukurikije ubunini bw'igitambaro gishobora kugabanywamo ifeza y'ibanze, ifeza ya kabiri, ifeza inshuro eshatu, ifeza inshuro enye, ifeza nyinshi zashizweho, byerekana ingaruka nziza yo kugicucu, ingaruka zo gutwikira ibyiyumvo byiza bizagaragara ko zizaba zikonje, usibye kole ya feza, hariho umutaka wa "kole y'amabara" na "umukara wirabura", ingaruka zo guhagarika urumuri nazo ni nziza
Mubyukuri, intego yumutaka hamwe na reberi ya feza mu gicucu, aho kurwanya anti-UV, ariko kandi kubera ko UV-B yinjira izaba ifite intege nke, hariho umutaka urwego rwinzitizi zumubiri, ingaruka zimwe ni ukurinda izuba.
Ariko mubyukuri, ntabwo byemewe gukoresha umutaka hamwe na kole ya silver, kubwimpamvu ebyiri.

2. Igice cyimbere cyumutaka hamwe na reberi ya feza, bizagaragaza kugabanuka kumirasire yumurambararo muremure, nkingaruka ya pariki yibitekerezo bitagira ingano byerekana inyuma, ubushyuhe burimo, ndetse bushobora no gufata umwijima ushushe!
Kubwibyo, nkumutanga wumwuga utanga umwuga, dukoresha gusa ubuziranenge bwiza bwa UV icapisha kumurongo. Nta bintu bya shimi bizasohoka hanze yumutaka. Byongeye kandi, gutwikira umukara ni amahitamo meza muri rusange.
