Byoroheje kandi byoroshye kuruta plastike, polikarubone (irwanya ingaruka) lens ntizishobora kumeneka kandi zitanga uburinzi bwa UV 100%, bigatuma bahitamo neza kubana nabakuze bakora. Nibyiza kandi kubyandikirwa bikomeye kuva batongeyeho umubyimba mugihe bakosora icyerekezo, bagabanya kugoreka kwose.
Lens ya Photochromic ni lens-adaptive lens ihindura imiterere itandukanye. Iyo mu nzu,lens irasobanutse kandi iyo ihuye nizuba ryizubahindukiraumwijima mu gihe kitarenze umunota.
Umwijima wamabara nyuma yo guhindura ibara rya fotochromic lens bigenwa nuburemere bwurumuri ultraviolet.
Lens ya fotokromike irashobora guhuza no guhindura urumuri, amaso yawe rero ntagomba gukora ibi. Kwambara ubu bwokoubushakefasha amaso yawe kuruhuka gato.
Hano hari amamiliyaridi ya molekile itagaragara imbere ya fotokromike. Iyo lens idahuye nurumuri ultraviolet, izo molekile zigumana imiterere isanzwe kandi lens ikomeza kuba mucyo. Iyo bahuye nurumuri ultraviolet, imiterere ya molekile itangira guhindura imiterere. Iyi reaction itera lens guhinduka ibara rimwe. Iyo lens zimaze kuva ku zuba, molekile zisubira muburyo busanzwe, kandi lens zongera kuba mucyo.
Birashobora guhinduka cyane kumiterere itandukanye yo kumurika murugo no hanze
Zitanga ihumure ryinshi, kubera ko zigabanya amaso no kurasa izuba.
Barahari kubisobanuro byinshi.
Rinda amaso imirasire yizuba ya UVA na UVB yizuba (kugabanya ibyago byo kurwara cataracte no guterwa nimyaka).
Bakwemerera guhagarika guhuza hagati yikirahure cyawe kirahure hamwe nizuba ryizuba.
Baraboneka mumabara atandukanye kugirango bahuze ibikenewe byose.
