Nigute ushobora kumenya niba indorerwamo zizuba zirinzwe UV?

Indorerwamohamwe no gukingira UV biterwa no kongeramo igifuniko kidasanzwe kuri lens, kandi indorerwamo zizuba ntizishobora guhagarika imirasire ya UV gusa, ariko kandi zigabanya cyane ihererekanyabubasha ryinzira, bigatuma abanyeshuri baba benshi, kandi imirasire ya ultraviolet izaterwa byinshi. , bigatera kwangiza amaso..Uyu munsi rero,Icyerekezooptique izagutwara kubyumva: nigute ushobora kumenya niba amadarubindi yizuba arinda UV?

Uburyo 1. Reba ikirango cyizuba.

Ibimenyetso bigaragara nka "UV kurinda", "UV400", nibindi bigaragara kuri label cyangwa lens ya UV-irwanyaindorerwamo."UV index" ningaruka zo kuyungurura imirasire ya ultraviolet, nigipimo cyingenzi cyo kugura amadarubindi.Umucyo ufite uburebure bwa 286nm-400nm witwa urumuri ultraviolet.Muri rusange, indangagaciro ya UV 100% ntibishoboka.Indangantego ya UV yizuba ryinshi riri hagati ya 96% na 98%.

Indorerwamo zizuba zifite imikorere ya anti-ultraviolet muri rusange zifite inzira zikurikira:

a) Shyira akamenyetso "UV400": ibi bivuze ko uburebure bwumurongo wa lens kugera kumucyo ultraviolet ari 400nm, ni ukuvuga, agaciro ntarengwa τmax (λ) yumubyigano wikurikiranya kumuraba (λ) munsi ya 400nm ntabwo urenze 2%;

b) Shyira akamenyetso "UV" na "UV kurinda": ibi bivuze ko uburebure bwumurongo wa lens kuri ultraviolet ari 380nm, ni ukuvuga, agaciro ntarengwa τmax (λ) kwohereza ibintu kuri spécialité ku burebure (λ) munsi ya 380nm ntabwo irenze 2%;

c) Shyira akamenyetso "100% UV"

Indorerwamo zizuba zujuje ibisabwa haruguru ni indorerwamo zizuba zirinda imirasire ya ultraviolet muburyo nyabwo.

Uburyo 2. Koresha ikaramu yerekana inoti kugirango urebe neza

Mugihe hatabayeho ibikoresho, abantu basanzwe nabo barashobora kumenya niba indorerwamo zizuba zifite uburinzi bwa UV.Fata inoti, shyira indorerwamo z'izuba ku kimenyetso cy’amazi arwanya impimbano, hanyuma ufate ifoto kuri lens hamwe na detektori cyangwa amafaranga.Niba ushobora kubona ikirangantego cyamazi, bivuze ko indorerwamo zizuba zitarwanya UV.Niba udashobora kubibona, bivuze ko indorerwamo zizuba zirinzwe UV.

Kurangiza muri make ibyavuzwe haruguru: Uburyo bwa 2 nigenzura ryaindorerwamoikirango muburyo bwa 1. Birashobora kugaragara hafi niba ikirango cyumucuruzi aricyo kandi niba indorerwamo zizuba zifite imikorere ya anti-ultraviolet.Mugihe ugura amadarubindi yizuba, urashobora kubigerageza.Muburyo bwo kugura no kwambara, niba ufite ikibazo, nyamuneka reba ibisobanuro birambuye.
