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.
Mugihe ibice bibiri bifata ibyerekezo bibiri bikosora icyerekezo cya kure kandi cyegereye, Ibintu birebire byamaboko bizakomeza kugaragara neza. Lens igenda itera imbere kurundi ruhande, igaragaramo zone eshatu zitagaragara zerekwa- hafi, kure na hagati.
Niba uri abarwayi ba presbyopiya kandi ukaba umara umwanya munini hanze, nibyiza guhitamo fotokromike itera imbere. Kuberako ntabwo arinda amaso yawe imirasire yizuba yizuba gusa, ahubwo inaguha icyerekezo cyiza kandi cyiza mubice bitandukanye.
Kuba wambara amadarubindi ya presbyopiya muminsi yizuba birashobora kuba ikibazo. Tugomba kwambara ibirahuri byamafoto cyangwa ibirahure byo gukosora? Lens ya Photochromic igenda itera imbere izagufasha gukemura iki kibazo kinini kuko ubu bwoko bwa lens bufite uburinzi bwizuba hamwe nibisobanuro byose hamwe!
