Ingaruka z'izuba

Imirasire ya Ultraviolet irashobora kwangiza cornea na retina, kandi indorerwamo zizuba nziza zirashobora gukuraho burundu ultraviolet.
Iyo ijisho ryakiriye urumuri rwinshi, mubisanzwe rwanduza iris.Iris imaze kugabanuka kugera aho igarukira, abantu noneho bakeneye kwikinisha.Niba hakiri urumuri rwinshi, nk'urumuri rw'izuba rugaragarira mu rubura, kwangirika kwa retina bizabaho.Indorerwamo yizuba nziza irashobora gushungura kugeza kuri 97% yumucyo winjira mumaso yawe kugirango wirinde kwangirika.
Ubuso bumwe, nkamazi, bugaragaza urumuri rwinshi, kandi ibibara bivamo bishobora kurangaza kureba cyangwa guhisha ibintu.Indorerwamo zizuba zifite ubuziranenge zirashobora gukuraho burundu ubu bwoko bwurumuri ukoresheje tekinoroji ya polarize, tuzabisuzuma nyuma.
Inshuro zimwe zumucyo utagaragara, mugihe izindi frequency zongera itandukaniro.Hitamo ibara ryiza kumadarubindi yawe kugirango ukore neza mubidukikije runaka.

Niba amadarubindi yizuba adatanga UV kurinda, azaguhishurira imirasire ya UV.Indorerwamo zizuba zihenze zungurura urumuri, bigatuma irise yawe ifunguka kugirango yakire urumuri rwinshi.Ibi bizemerera kandi imirasire myinshi ya ultraviolet kwinjira, byongere ibyangiritse biterwa nimirasire ya ultraviolet kuri retina.
Kubwibyo, mubyukuri hariho itandukaniro hagati yubwoko butandukanye bwizuba.Guhitamo neza, indorerwamo yizuba nziza kugirango ukoreshe ibidukikije bizaguha uburinzi bukomeye.
Ukurikije amahame mpuzamahanga, indorerwamo zizuba zishyirwa mubicuruzwa bikingira amaso.Igikorwa nyamukuru cyamadarubindi nuguhagarika urumuri rwizuba.Ariko, ibipimo mpuzamahanga bigabanya amadarubindi yizuba "ibirahuri by'imyambarire" n "" ibirahuri rusange. "Ibisabwa byujuje ubuziranenge kuri "indorerwamo z'imyambarire" mubipimo biri hasi.Kuberako kwibandaho cyane "indorerwamo zimyambarire" nuburyo, uwambaye yitondera imitako aho gukora umurimo wo kurinda.Ibipimo ngenderwaho bisabwa kugira ngo "ibirahuri bigamije rusange birakaze, harimo n'ibisabwa kurinda UV, diopter na prism power."
