Indorerwamo za mudasobwa 1.59 za Progressive Photochromic Gray HMC Optical lenses
Lens ihindura amabara ishingiye ku ihame rya tautometry ya photochromatic ishobora guhindurwa, lens ishobora kwijima vuba iyo hari urumuri rukomeye n'urumuri rwa ultraviolet, igafunga urumuri rukomeye kandi igafata urumuri rwa ultraviolet; Nyuma yo gusubira mu mwijima, lens isubiza vuba imiterere idafite ibara kandi ibonerana kugira ngo ihereze lens. Kubwibyo, lens ihindura amabara ikwiriye cyane haba mu nzu no hanze, cyane cyane mu bidukikije byo hanze kugira ngo hirindwe urumuri rukomeye, ultraviolet, glare n'ibindi byangiza amaso, ikwiriye hanze cyane, amaso ashobora kwitabwaho n'urumuri, igagabanya umunaniro w'amaso. Nyuma yo kwambara indorerwamo zihindura amabara, uzabona neza kandi neza iyo uri mu rumuri rukomeye, wirinde gukora ingendo zishyushye nko gukubita amaso, kandi ugabanye umunaniro w'amaso n'imitsi ikikije amaso.
