Lens ya Photochromic ni lens-adaptive lens ihindura imiterere itandukanye. Iyo mu nzu, lens irasobanutse kandi iyo ihuye nizuba, ihinduka umwijima mugihe 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 bwoko bwa lens bizafasha 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 kuburyo butandukanye bwo kumurika murugo no hanze
☆ Zitanga ihumure ryinshi, kubera ko zigabanya amaso no kurabagirana ku zuba.
☆ Baraboneka kubisobanuro byinshi.
Kurinda amaso imirasire yizuba ya UVA na UVB yizuba (kugabanya ibyago byo kurwara cataracte no guterwa nimyaka).
☆ Bakwemerera guhagarika guhuzagurika hagati yikirahure cyawe kirahure hamwe nizuba ryizuba.
Available Baraboneka mumabara atandukanye kugirango bahuze ibikenewe byose.
