Twerekeza ku mucyo ijisho ry'umuntu rishobora kubona nk'urumuri rugaragara, ni ukuvuga, "umutuku w'umuhondo umutuku icyatsi kibisi icyatsi kibisi".
Ukurikije ibipimo ngenderwaho byinshi byigihugu, urumuri rugaragara mumurambararo wa 400-500 nm rwitwa urumuri rwubururu, arirwo rugufi rugufi n’umucyo ufite ingufu (HEV) mumucyo ugaragara.
Itara ry'ubururu riri hose mubuzima bwacu.Imirasire y'izuba niyo soko nyamukuru yumucyo wubururu, ariko amasoko menshi yumucyo wubukorikori, nkamatara ya LED, ecran ya TVS hamwe na ecran ya digitale nka mudasobwa na terefone zigendanwa, nayo itanga urumuri rwinshi rwubururu.
Birakwiye ko tumenya ko mugihe HEV yasohowe nibi bikoresho ari nto ugereranije n’izuba ritangwa nizuba, umwanya abantu bamara kuri ibyo bikoresho bya digitale urenze cyane igihe bahura nizuba.
Itara ry'ubururu rirashobora kuba ribi cyangwa ryiza kuri twe, bitewe nigihe cyo kugaragaramo, ubukana, intera yumurambararo nigihe bimara.
Kugeza ubu, ibisubizo bizwi mubushakashatsi byose bizera ko ikintu nyamukuru cyangiza ijisho ryumuntu ari urumuri rugufi rwubururu ruri hagati ya 415-445nm, imirasire yigihe kirekire, bizatera kwangirika kwijisho ryumuntu;Umucyo muremure wubururu hejuru ya 445nm ntabwo wangiza amaso yumuntu gusa, ahubwo unagira uruhare runini mubitekerezo bya biologiya.
Kubwibyo, kurinda urumuri rwubururu bigomba "kuba" neza, guhagarika urumuri rwubururu rwangiza no kureka urumuri rwubururu rukagira akamaro.
Ibirahuri birwanya ubururu kuva mubwoko bwa mbere bwa substrate yo kwinjiza (tan lens) kugeza mubwoko bwerekana amashusho, ni ukuvuga gukoresha ikoreshwa rya firime kugirango ugaragaze igice cyumucyo wubururu, ariko hejuru yuburinganire buragaragara cyane;Noneho kubwoko bushya bwa lens idafite ibara ryinyuma hamwe nogukwirakwiza urumuri rwinshi, ibicuruzwa byubururu birwanya ibirahure nabyo bihora bivugururwa kandi bigasubirwamo.
Muri iki gihe, isoko ryagaragaye kandi amafi amaso avanze amasaro, ibicuruzwa bidahwitse.
Kurugero, ubucuruzi bumwe na bumwe bwo kumurongo bugurisha ibirahuri byubuvuzi byubururu kubaguzi basanzwe.Ibirahuri byambere bikoreshwa kubarwayi basuzumwe indwara ya macula cyangwa abarwayi bamwe bakira kubagwa amaso, ariko bigurishwa nka "100%-bifunga ubururu".
Ubu bwoko bwibirahure birwanya ubururu, ibara ryinyuma rya lens ni umuhondo cyane, iyerekwa rizagoreka, kwanduza ni bike cyane ariko byongera ibyago byo kunanirwa kubona;Igipimo cyumucyo wubururu kiri hejuru cyane kugirango uhagarike urumuri rwubururu.
Kubwibyo, abantu ntibagomba kwibeshya "ibicuruzwa byiza" kubera ikirango "ubuvuzi".
Mu rwego rwo kwemeza imikorere n’ubuziranenge bw’ibicuruzwa birinda blu-ray, muri Nyakanga 2020, hashyizweho ibipimo ngenderwaho bijyanye na "GB / T 38120-2019 Filime yo gukingira Blu-ray, ubuzima bw’umucyo n’ibisabwa mu rwego rwa tekiniki bisabwa tekiniki" ku bicuruzwa birinda blu-ray.
Rero, mugihe abantu bose bahisemo KUBURA ibirahuri byamatara yubururu, bagomba kureba KUBipimo byigihugu.
