1.56 Bifocal Round Hejuru Ifoto Yumukara Icyatsi HMC Lens optique

1.56 Bifocal Round Hejuru Ifoto Yumukara HMC Lens optique Yerekana Ishusho

Ibisobanuro bigufi:

Ibirahuri bya bifocal birakwiriye cyane cyane abasaza gukoresha, kandi birashobora kugera kure. Abantu nibasaza, amaso yabo azagabanuka kandi amaso yabo azabe umusaza. Kandi ibirahuri bifocal birashobora gufasha abageze mu zabukuru kubona kure no kubona hafi.

Lens ebyiri nazo zitwa lens ya bifocal, zirimo cyane cyane lens yo hejuru hejuru, lens top top lens hamwe na lens itagaragara.

Ibirahuri byibirahuri bisabwa gushyiramo hyperopiya diopter, myopia diopter cyangwa itara. Intera ya kure y'abanyeshuri, hafi yintera yabanyeshuri.

Ukurikije ihame rya fotokromike isubiranamo rishobora guhinduka, irashobora kwijimye vuba munsi yumucyo wizuba hamwe nimirasire ya ultraviolet, ikakira neza urumuri ultraviolet, kandi igakurura urumuri rugaragara muburyo butabogamye; Tugarutse ahantu hijimye, irashobora kugarura byihuse ibara ridafite ibara. Ikoreshwa cyane cyane hanze, ahantu h'urubura no mu nzu hamwe n’amasoko akomeye y’umucyo kugirango wirinde kwangirika kwamaso yatewe nizuba ryizuba, urumuri ultraviolet hamwe nurumuri.

Ibara rihindura ibara rishobora guhindura ibara rihindura uburebure hamwe nuburemere bwurumuri ultraviolet. Urumuri ultraviolet rukomeye, ibara ryijimye. Ibinyuranye na byo, intege nke za ultraviolet nizo zigenda zoroha, ibara rike rigenda rihinduka mu mucyo. Ihame ni uko uduce duto twa silver halide twongewemo mu bikoresho fatizo bya lens, naho igice cya feza kikabora mo ion ya halogene na ion zakozwe na. ultraviolet urumuri rwo guhindura ibara.

Intangiriro

1. Umuvuduko wamabara uhinduka: Iyo lens nziza yo guhindura ibara ihuye nurumuri ultraviolet hanze, umuvuduko wamabara wihuta cyane, kandi nayo irashira vuba mumazu.

2. Guhindura ibara kumurongo rusange uhindura ibara rishobora kuba rito.

3. Ihuriro ryamabara ahinduranya lens hamwe ahanini murwego rumwe cyangwa membrane ihindura lens, kandi ibara rihindura umuvuduko nuburebure bwimbaraga zombi zirasa. Ntabwo hagomba kubaho ikibazo cyumuntu ufite ibara ryimbitse kandi nimwe ifite ibara ryoroshye
