Ibiranga Lens ya Acrylic

A. Ubucucike buke: kubera ikinyuranyo hagati yiminyururu ya molekile, umubare wa molekile kuri buri gice ni gito, ugena ibyiza bya lens ya resin: uburemere buke bwihariye nuburyo bworoshye, aribwo 1 / 3-1 / 2 bya ikirahuri cy'ikirahure;

B. Icyerekezo gike cyo kugabanya: bisanzwe CR-39 propylene diethylene glycol karubone, indangagaciro ni 1.497-1.504.Kugeza ubu, indangagaciro yo kwangirika cyane ya resin yagurishijwe ku isoko ry’ibirahuri bya Shenyang ni aspherical ultra-thin hardened firime resin lens, kugabanura Igipimo gishobora kugera kuri 1.67, kandi ubu hariho lens ya resin ifite indangagaciro ya 1.74.

C. Ubukomere bwubuso buri munsi yikirahure, kandi biroroshye gushushanya nibintu bikomeye.Kubwibyo, bigomba gukomera.Ibikoresho bikomye ni silika, ariko gukomera ntabwo ari byiza nkuburemere bwikirahure.Kubwibyo, uwambaye agomba kwitondera lens.kubungabunga;

D. Elastique ni nziza.Bitewe n'umwanya uri hagati y'iminyururu ngengabuzima, elastique ikubye inshuro 23-28 z'igice cy'ikirahure.Ikindi kintu cyingenzi kiranga urupapuro rwabigenewe - kurwanya ingaruka nziza.Ibihugu by’Uburayi, Amerika, n’Ubuyapani bibuza abana bari munsi y’imyaka 16 kwambara ibirahuri;

E. Igikorwa cyo gufasha: Irashobora kongerwaho kugirango ibone imirimo nko gukumira imirasire yangiza no guhindura ibara.
