Ibicuruzwa biranga ibicuruzwa
1.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.
2. Ubugari bwa kabiri bwa Lens ya Bifocal ni ubuhe?
Lens Lens irahari hamwe nubugari bumwe: 28 mm. Umubare nyuma ya "CT" mu izina ryibicuruzwa yerekana ubugari bwa kabiri muri milimetero.
3.Ni ubuhe buryo bwa mbere 28 imyenda ya bifocal?
Lens ya mbere ya mbere itanga ubugororangingo haba hafi ya kure. Ni lens nyinshi zakunze gutegekwa kubabazwa na preskyopia zombi na hypermetropia zombi, hashize igihe, bafite imyaka, ijisho ryerekana iterambere ryiterambere ryibandaho hafi nibintu bya kure. Igorofa yo hejuru ikubiyemo igice kuri kimwe cya kabiri cya lens hamwe no kwandika kugirango usome (hafi ya kure). Ubugari bwimyenda 28 bifocal ni 28mm z'ubugari hejuru yimbwa kandi isa ninyuguti d yujuje impamyabumenyi ya dogere 9.
Kuberako igorofa yo hejuru yimyenda nimwe mubiturage byinshi byoroshye kugirango bimenyereye, nimwe mubintu bishaje bya bifocal kwisi. Biratandukanye "gusimbuka" kuva kure kugeza hafi yegereye iyerekwa biha abashakanye ahantu habiri mubirahure zabo kugirango bakoreshe, bitewe numurimo uriho. Umurongo uragaragara kuko impinduka mububasha zihita hamwe ninyungu ziguha umwanya wo gusoma cyane utiriwe ugaragara cyane kuri lens. Biroroshye kandi kwigisha umuntu gukoresha bifikocal kuko ukoresha hejuru gusa kugirango usome.
4. Ni irihe tandukaniro riri hagati ya HC, HMC na SHC?
| Gutwika cyane | Ar guswera / gukomera cyane | Icyubahiro cya Hydrophobike |
| ituma lens itagereranywa kandi yongera ibyuma bya ambusion | Yongera Gufatanyirizwa Lens kandi bigabanya ibintu byubuso | ituma lens itangwaga, antilasit, anti kunyerera hamwe namavuta |
