Kudasobanukirwa guhitamo amadarubindi.

Indorerwamo zizuba zose zirwanya UV 100%
Reka tubanze twumve urumuri ultraviolet.Uburebure bwumucyo ultraviolet uri munsi ya 400 uv.Ijisho rimaze kugaragara, byangiza cornea na retina, bikaviramo keratite yizuba hamwe na corneal endothelial yangirika.
Indorerwamo zizuba zifite imikorere ya anti-ultraviolet muri rusange zifite inzira nyinshi zisobanutse:
1. Shyira akamenyetso “UV400 ″:
Bishatse kuvuga ko uburebure bwumurambararo wa lens kugera kumirasire ya ultraviolet ni 400nm, ni ukuvuga, agaciro ntarengwa ko kohereza kwayo kwerekanwa kumuraba uri munsi ya 400nm ntishobora kurenza 2%.
2. Shyira akamenyetso kuri “UV”, “UV kurinda”:
Irerekana ko uburebure bwumurongo wa lens irwanya imirasire ya ultraviolet ni 380nm.
3. Shyira akamenyetso “100% UV yinjira”:
Bishatse kuvuga ko lens ifite 100% yo kwinjiza imirasire ya ultraviolet, ni ukuvuga ko impuzandengo yoherejwe mu ntera ya ultraviolet itarenze 0.5% .Muri rusange, gusa abafite ibimenyetso byavuzwe haruguru bashobora gufatwa nkamadarubindi yizuba afite umurimo wo gukingira imirasire ya ultraviolet mubyukuri.

Amadarubindi yizuba aruta amadarubindi asanzwe
Amadarubindi yizuba yizuba, usibye imikorere yizuba, arashobora kandi gucika intege no guhagarika akajagari
Yagaragaje urumuri, urumuri, ibintu bidasanzwe byerekana ibintu, nibindi, kandi unyuze ihererekanyabubasha ryinzira iboneye kuri
ijisho ryo kwiyumvisha no gutuma iyerekwa rikungahaye Urwego, iyerekwa rirasobanutse kandi karemano.Polarizeri muri rusange
bikwiranye nibikorwa byo hanze nko gutwara, kuroba, ubwato, gufata amazi yera, no gusiganwa ku maguru. Nkuko ibara rya
lensiseri ya polarizer muri rusange yijimye, ntabwo ari ngombwa kuyambara muminsi yibicu cyangwa mumazu.Ugomba guhitamo
amadarubindi asanzwe kugirango arinde amaso yawe imirasire ya ultraviolet.
