(1) yoroheje kandi yoroheje
Ibipimo bisanzwe byangirika bya lens ya CONVOX ni: 1.56, 1.59, 1.61, 1.67, 1.71, 1.74.Kurwego rumwe, urwego rwo hejuru rwerekana indangururamajwi, nubushobozi bwo kugabanya urumuri rwibyabaye, ubunini buke nuburemere buremereye.Byoroheje kandi byoroshye kwambara.
(2) Kugaragara
Indangantego yo kugabanya ntabwo igena ubunini bwinzira gusa, ahubwo inagira ingaruka kuri numero ya Abbe.Umubare munini wa Abbe, niko gutatanya.Ibinyuranye, umubare muto wa Abbe, niko gutatanya, no kwerekana amashusho neza.Ariko muri rusange tuvuze, uko urwego rwo hejuru rwangirika, niko rutandukana, bityo ubunini no gusobanuka kwinzira akenshi ntibishobora kwitabwaho.
(3) Itumanaho ryoroheje
Itumanaho ryoroheje naryo ni kimwe mubintu bigira ingaruka kumiterere yinzira.Niba urumuri rwijimye cyane, kureba ibintu igihe kirekire bizatera umunaniro ugaragara, utabereye ubuzima bwamaso.Ibikoresho byiza birashobora kugabanya neza gutakaza urumuri, kandi ingaruka zo kohereza urumuri nibyiza, bisobanutse kandi bisobanutse.Kuguha icyerekezo cyiza.
(4) Kurinda UV
Umucyo Ultraviolet ni urumuri nuburebure bwa 10nm-380nm.Imirasire ikabije ya ultraviolet izangiza umubiri wumuntu, cyane cyane amaso, ndetse itera ubuhumyi mubihe bikomeye.Muri iki gihe, imikorere yo kurwanya ultraviolet ya lens ni ngombwa cyane.Irashobora guhagarika neza imirasire ya ultraviolet itagize ingaruka kumyuka yumucyo ugaragara, kandi ikarinda kureba neza bitagize ingaruka kumaso.
