Bitandukanye n'indorerwamo z'izuba zisanzwe cyangwa lentile za photochromic zigabanya gusa urumuri, lentile za UV400 ziyungurura imirasire yose y'urumuri ifite uburebure bw'uburebure bugera kuri nanometero 400. Ibi birimo UVA, UVB n'urumuri rw'ubururu rugaragara cyane (HEV).
Kugira ngo bifatwe nk'indorerwamo za UV, lenses zisabwa kuziba 75% kugeza 90% by'urumuri rugaragara kandi zigomba gutanga uburinzi bwa UVA na UVB kugira ngo ziziba 99% by'imirasire ya UV.
Mu by’ukuri, wifuza indorerwamo z’izuba zifite uburinzi bwa UV 400 kuko zirinda hafi 100% imirasire ya UV.
Menya ko atari indorerwamo z'izuba zose zifatwa nk'indorerwamo z'izuba zirinda imirasire ya UV. Indorerwamo z'izuba zishobora kuba zifite indorerwamo z'umukara, zishobora gufatwa nk'izifunga imirasire y'izuba, ariko ibyo ntibivuze ko indorerwamo zitanga uburinzi buhagije ku mirasire ya UV.
Niba izo ndorerwamo z'izuba zifite indorerwamo z'umukara zidafite uburinzi bwa UV, ayo mabara yijimye mu by'ukuri aba mabi ku maso yawe kuruta kutambara imyenda irinda amaso na gato. Kuki? Kubera ko ibara ryijimye rishobora gutuma amaso yawe yaguka, bigatuma amaso yawe abona urumuri rwinshi rwa UV.
Namenya nte ko indorerwamo zanjye zifite uburinzi bwa UV?
Ikibabaje ni uko bigoye kumenya niba indorerwamo z'izuba cyangwa amatara ya photochromic afite amatara ya UV urebye gusa.
Ntabwo ushobora gutandukanya ingano y'uburinzi ukurikije ibara ry'ikirahuri, kuko amabara y'ikirahuri cyangwa umwijima ntaho bihuriye no kurinda imirasire ya UV.
Icyiza cyawe ni ukujyana indorerwamo zawe mu iduka ricuruza amashusho cyangwa mu bigo by’abahanga mu gupima. Bashobora gukora ikizamini cyoroshye ku ndorerwamo zawe kugira ngo bamenye urwego rw’uburinzi bwa UV.
Cyangwa amahitamo yoroshye ni ugushyira ishakisha ryawe ku ruganda rw’indorerwamo rw’abahanga kandi rwizewe nka UNIVERSE OPTICAL, hanyuma ugahitamo indorerwamo nyazo za UV400 cyangwa lentile za UV400 photochromic kuri paji.https://www.universeoptical.com/1-56-aspherical-uv400-q-active-material-photochromic-lens-product/.
