Ni ubuhe bwoko bw'ubururu n'impamvu ugomba kugura lensre yubururu?

Itara ry'ubururu ni urumuri rugaragara hamwe nuburebure buke bwumurage nimbaraga zisumba izindi, kandi bisa na ultraviolet imirasire, itara ry'ubururu rifite inyungu ningaruka zombi.

Mubisanzwe, abahanga bavuga ko urumuri rugaragara rugizwe nimirasire ya electomagnetic hamwe nuburebure bwa Navelet buturutse muri 380 nanometero (nm) kumpera ya 700 kurupapuro rutukura. .

Umucyo w'ubururu muri rusange usobanurwa nkumucyo ugaragara kuva kuri 380 kugeza 500 nm. Umucyo w'ubururu rimwe na rimwe uracikamo urumuri rw'ubururu-violet (hafi 350 kuri 450 nm) n'ubururu-turquoise urumuri (hafi ya 450 kugeza 500 nm).

Rero, hafi ya kimwe cya gatatu cyumucyo ugaragara ufatwa nkimbaraga-zigaragara (hev) cyangwa "ubururu".

Hano haribimenyetso byerekana urumuri rwubururu bishobora kuganisha ku iyerekwa rihoraho. Hafi yubururu bwose bwubururu inyura inyuma ya retina yawe. Ubushakashatsi bumwe bwerekanye urumuri rwubururu bushobora kongera ibyago byo kwangirika kwa macular, indwara ya retina.

Ubushakashatsi bwerekana uburyo bworoshye bworoshye bushobora gutuma abantu bifitanye isano na macilar ya macilar, cyangwa amd. Ubushakashatsi bumwe bwabonye itara ry'ubururu bwateje irekurwa rya molekile y'ubumara muri selile selile. Ibi bitera ibyangiritse bishobora gutera amd.

Hashize imyaka itari mike, twateje imbere igisekuru cya mbere cyalens yo guhagarika umutima.Hamwe no guhanga udushinga mugihe cyashize, ibyaculensle yubururubitezwa imbere nkibisanzwe bishoboka kugirango bitagaragara.

IbyacubLue Kubuzalensbafite icyumba cyo guhagarika cyangwa gukuramo itara ry'ubururu. Bivuze niba ukoreshaibilensesIyo urebye kuri ecran, cyane cyane nyuma yumwijima, barashobora gufasha kugabanya guhura numucyo wubururu ushobora gukomeza kuba maso kandi bagafasha kugabanya amaso. Ariko, abantu bamwe bavuga urumuri rwubururu mubikoresho bya digital ntibitera eyestrain. Ibibazo abantu binubira byatewe no gukoresha imikoreshereze ya digitale.
