Mu kurinda ibikoresho n'ibicuruzwa ingaruka mbi z'izuba, hari inyongera ebyiri zikunze gukoreshwa: UV absorbers naibintu bitera imbaraga urumuriNubwo bisa, ibyo bintu byombi mu by’ukuri bitandukanye cyane mu mikorere yabyo ndetse n’urwego rw’uburinzi bitanga.

Nk’uko izina ribisobanura, ibikoresho bikura imirasire ya UV bikura imirasire ya ultraviolet (UV) ituruka ku zuba. Imirasire ya UV izwiho kwangirika kw'ibintu byinshi, cyane cyane ibyo ku zuba rimara igihe kirekire. Ibikoresho bikura imirasire ya UV bikora mu gukurura imirasire ya UV bikayihindura ubushyuhe, hanyuma bigashira burundu.

Ku rundi ruhande, ibyuma bitera imbaraga mu gukingira kwangirika kw'ibintu biterwa n'imirasire ya ultraviolet n'urumuri rugaragara. Ibikoresho bitera imbaraga mu mirasire ya ultraviolet byibanda gusa ku kurinda imirasire ya ultraviolet, mu gihe ibyuma bitera imbaraga mu mirasire ya ultraviolet bitanga uburinzi bwagutse. Ntabwo bitera imbaraga mu mirasire ya ultraviolet gusa, ahubwo binafata ibintu bitera imbaraga mu mirasire ya ultraviolet bituruka ku mucyo ugaragara.

Uruhare rwaibintu bitera imbaraga urumurini ukugabanya imisemburo y’ubusa no kuyirinda kwangiza ibikoresho. Ibi bituma igira uruhare runini mu kugabanya umuvuduko w’ibikorwa byo kwangirika kw’ibikoresho bikunze kugaragara mu bidukikije byo hanze. Mu gukumira ikorwa ry’imisemburo y’ubusa, ibintu bitera imbaraga urumuri bifasha kongera igihe cy’ibikorwa no kugumana imiterere yabyo.

Byongeye kandi, ibintu bitera imbaraga z'urumuri akenshi bihuzwa naUtwuma dufata UVkugira ngo birinde burundu ingaruka z'izuba. Nubwo ibikoresho bigabanya imirasire ya UV byibanda ahanini ku ngaruka z'imirasire ya UV, ibikoresho bitera imbaraga fotostabilizer byongera ubundi buryo bwo kurinda binyuze mu gukuraho radicals yigenga ikomoka ku rumuri rugaragara. Mu gukoresha inyongera zombi hamwe, ibikoresho birindwa ubwoko bwinshi bw'imirasire yangiza.

Irindi tandukaniro riri hagati y'ibikoresho bigabanya imirasire ya UV n'ibinyabutabireibintu bitera imbaraga urumurini uburyo bikoreshwa kandi bihura n'ibikoresho bitandukanye. Ibikoresho bigabanya imirasire y'izuba bikunze gukoreshwa mu gusiga irangi risobanutse, filime na polimeri kuko byagenewe kuba bibonerana kandi ntibigire ingaruka ku isura y'ibikoresho. Ku rundi ruhande, ibitera imbaraga byo gusiga urumuri birakora cyane kandi bishobora gukoreshwa mu buryo butandukanye, harimo pulasitiki, rabha, amarangi, n'imyenda.

Muri make, nubwo ibikoresho bigabanya imirasire ya UV n'ibigabanya imirasire ya fotostabilizeri bikoreshwa mu kurinda ibikoresho kwangirika bitewe n'izuba, bitandukanye mu mikorere yabyo n'urwego rw'uburinzi. Ibikoresho bigabanya imirasire ya UV bikura imirasire ya UV, mu gihe ibigabanya imirasire ya UV bikumira kwangirika guterwa n'imirasire ya UV n'urumuri rugaragara binyuze mu gukuraho uturemangingo tw'ingufu. Mu gusobanukirwa itandukaniro riri hagati y'ibi bikoresho, ababikora bashobora guhitamo uburyo bwiza bwo kubikoresha no kwemeza ko ibikoresho byabo birindwa neza.
