1.59 PC Bifocal Itagaragara Ifoto Yumukara HMC Lens Optical lens Yerekanwe

Ibisobanuro bigufi:

Kugeza ubu, hari ubwoko bubiri bwibikoresho bya lens ku isoko, kimwe ni ibikoresho byikirahure, ikindi ni ibikoresho bya resin.Ibikoresho bya resin bigabanijwemo CR-39 na polyakarubone (ibikoresho bya PC).

Indwara ya Bifocal cyangwa lens ya bifocal ninzira zirimo uduce tubiri dukosora icyarimwe kandi zikoreshwa cyane mugukosora presbyopiya.Agace ka kure gakosowe na lens ya bifocal bita akarere ka kure, naho agace kegereye agace kegereye hamwe n’ahantu ho gusomera.Mubisanzwe, akarere ka kure ni nini, bityo nanone yitwa firime nkuru, kandi akarere kegeranye ni nto, bityo bita sub-film.

Ni ibihe bintu biranga ibirahuri?Gukomera cyane, nta gukomera, byoroshye gucika iyo ukubiswe.Ifite umucyo mwinshi no kohereza urumuri rwa 92 ku ijana.Mu buryo bwa shimi nu mubiri, birashobora kurwanya ingaruka zubwoko bwose bwikirere, kandi ntibisiga amabara, ntibishire.Kubera uburemere bwacyo, ntibikwiye ingimbi.

Ni izihe nyungu za resin lens?Indwara ya resin ikozwe muri diethylene glycol na propylene glycol lipid reaction polymerisation.Uburemere bworoshye, kurwanya ingaruka nziza, kurwanya ubushyuhe bwinshi, kohereza urumuri rwiza, hafi yimikorere yibirahuri, birashobora guhagarika imirasire ya ultraviolet.

Ni izihe nyungu za lens ya PC?Lens ya PC izwi kandi nka: igice cyumwanya cyangwa umwanya, bikozwe mubikoresho byo murwego rwa optique PC mugutunganya inshinge.Ifite uburemere bworoshye, imbaraga nyinshi zingaruka, guhangana nikirere cyiza, kohereza urumuri rwiza, kwinjiza 100% ultraviolet, kutagira uburozi, no kurengera ibidukikije, hamwe niterambere ryinshi.

Intangiriro

Byinshi bifocals bikoreshwa mugusimbuza ibice bibiri bya bifocal bikoreshwa mukureba kure no kureba hafi, bityo umwanya nubunini bwahantu harebwa kure hamwe n’ahantu hareberwa hagomba guhura nibirahuri bibiri byikirahure.Niba iyerekwa ryegereye ariryo ryiganje, sublices irashobora kuba nini kandi ihagaze hejuru;Kurundi ruhande, niba igihe kinini cyakoreshejwe ureba kure, ibice-bito bizaba bito kandi biri munsi mumwanya.Nta bwoko bumwe bwo gushushanya bushobora guhuza ibikenewe mubihe bitandukanye.Igomba gutoranywa kandi igahuzwa ukurikije ibyifuzo bifatika byerekana abambara, kandi rimwe na rimwe bigomba gukoreshwa kugirango bihuze ibyifuzo bikenewe mubihe bitandukanye kandi bitandukanye.
