Seto 1.56 kuzenguruka-hejuru yimyenda lens HMC

Ibisobanuro bigufi:

Nkuko izina ryerekana ko bifcocal izengurutse hejuru. Bambere bagenewe gufasha abatwara kugera ahantu ho gusoma byoroshye. Ariko, ibi bigabanya ubugari bwa hafi yegeranijwe hejuru yiki gice. Kubera iyi, bifkocals kuzenguruka ntabwo izwi cyane kuruta d seg.
Igice cyo gusoma gikunze kuboneka muri 28mm na 25mm. R 28 ni 28m z'ubugari hagati na R25 ni 25mm.

1.Ni izihe mpingamubiri?
Lens ya Bifocal bivuga lens ifite luminasity icyarimwe, kandi igabanya lens mubice bibiri, igice cyo hejuru cyacyo kireba ahantu hatagereranywa, kandi igice cyo hepfo ni agace kayo kariho.
Muri lens yimbwa, ahantu hanini mubisanzwe ni ahantu hato kabyo, mugihe agace ka myopic karimo igice gito gusa, igice gikoreshwa mubyiciro byibanze byitwa lens byibanze byitwa sub -Icyaha.
Duhereye kandi kandi twumve ko inyungu za bifocal ari uko bidakora gusa imikorere yo gukosorwa kure, ahubwo ifite imikorere yibikorwa bihendutse hafi-iyerekwa.

2.Ni ubuhe butumwa bwo hejuru?
Hejuru, umurongo ntabwo bigaragara nko hejuru. Ntabwo bigaragara ariko iyo yambarwa. Ikunda kumenyekana cyane. Irakora kimwe no hejuru, ariko umurwayi agomba kureba kure muri lens kugirango abone ubugari bumwe kubera imiterere ya lens.

3.Ni ibihe bintu biranga bifocal?
Ibiranga: Hariho ingingo ebyiri zibanze kuri lens, ni ukuvuga lens ntoya hamwe nubutegetsi butandukanye bikwiranye na lens isanzwe;
Ikoreshwa kubarwayi bafite preskopia kugirango babone kure kandi hafi yubutaka;
Hejuru ni Luminasotity iyo ireba kure (rimwe na rimwe igorofa), kandi urumuri rwo hasi ni Luminasity mugihe usoma;
Impamyabumenyi yintera yitwa Imbaraga zo hejuru hamwe na dogere Hafi Yitwa Imbaraga zo hasi, kandi itandukaniro riri hagati yububasha bwo hejuru nimbaraga zo hasi byitwa kongeramo (imbaraga zongeweho).
Ukurikije imiterere yikibanza gito, irashobora kugabanywamo ibice-byo hejuru-hejuru, bifice-hejuru-yo hejuru nibindi.
Ibyiza: Abarwayi ba Preskopiya ntibakeneye gusimbuza ibirahure iyo babonye hafi ndetse no kure.
Ibibi: Gusimbuka ibintu mugihe ureba kure no guhinduka;
Duhereye kubigaragara, bitandukanye na lens isanzwe.

4. Ni irihe tandukaniro riri hagati ya HC, HMC na SHC?
