1) Ni he duhura n'umucyo w'ubururu?
Itara ry'ubururu ni urumuri rugaragara hamwe nuburebure bwumuraba hagati ya 400 na 450 nanometero (nm). Nkuko izina ryerekana, ubu bwoko bwumucyo bufatwa nkubururu mumabara. Nyamara, urumuri rwubururu rushobora kuba rutahari nubwo urumuri rufatwa nk'urundi rubato cyangwa irindi bara. Inkomoko nini yurumuri rwubururu ni izuba. Byongeye kandi, hari andi masoko menshi arimo urumuri rwubururu:
Umucyo wa fluorescent
CFL (Compact fluorescent yoroheje) Amatara
Live
Screct Screct LET tereviziyo
Abagenzuzi ba mudasobwa, terefone zidahwitse, na tablet ya tablet
Ubururu bworoshye uhura na ecran ni gito ugereranije nuburyo bwo guhura nizuba. Kandi,, hari impungenge zingaruka ndende zo kwerekana amashusho kubera kuba hafi ya ecran ya ecran nuburebure bwigihe bamara. Nk'uko ubushakashatsi bwa Nei-batera inkunga, amaso y'abana akurura urumuri rw'ubururu kurusha abakuze bava mu gikoresho cya digitale.
2) Nigute urumuri rwubururu rugira ingaruka kumaso?
Hafi yubururu bwose bugaragara inyuze muri cornea na lens kandi ikagera kuri retina. Uyu mucyo urashobora kugira ingaruka ku iyerekwa kandi ushobora kwiga ubusa imburagihe amaso. Ubushakashatsi bwa mbere bwerekana ko guhura cyane numucyo w'ubururu bishobora gutera:
Digital Eystrain: Itara ry'ubururu kuva muri ecran ya mudasobwa nibikoresho bya digitale birashobora kugabanya itandukaniro riganisha kumaso ya digitale. Umunaniro, amaso yumye, kumurika nabi, cyangwa uko wicaye imbere ya mudasobwa birashobora gutera eyestrain. Ibimenyetso byamaso birimo amaso ye cyangwa arakaye hamwe ningorabahizi.
Ikirangabiti cya Retina: Ubushakashatsi bwerekana ko byakomeje guhura numucyo w'ubururu mugihe bishobora kuganisha kuri selile zangiritse. Ibi birashobora gutera ibibazo byereye nkibisaza.
Umucyo mwinshi w'ubururu uturutse ahantu hose ushobora guteza akaga ijisho. Inganda zifata urumuri rwubururu ziyungurura intego cyangwa zikingiwe kugirango urinde abakoresha. Ariko, birashobora kuba bibi kugaragara mu buryo butaziguye ibirayi by'amashanyarazi gusa kubera gusa ko ari byiza cyane. Harimo "urwego rwa gisirikare" amashusho hamwe nizindi matara.
Byongeye kandi, nubwo itara rya LED na itara rya lindentcent byombi bishobora kugaragazwa kumurika, imbaraga zumucyo ziva muri LED zishobora guturuka kumutwe wumutwe ugereranije nubuso bunini bwinkomoko. Urebye muburyo butaziguye ni akaga kubwimpamvu imwe gusa bidakwiriye kureba izuba riri mwijuru.
3) Ni irihe tandukaniro riri hagati ya HC, HMC na SHC?
