Makhalidwe a Acrylic Lens

A. Kachulukidwe kakang'ono: chifukwa cha kusiyana pakati pa maunyolo a molekyulu, kuchuluka kwa mamolekyu pa voliyumu imodzi ndi yaying'ono, yomwe imatsimikizira ubwino wa lens ya utomoni: mphamvu yokoka yotsika komanso mawonekedwe opepuka, omwe ndi 1/3-1/2 ya lens galasi;

B. Moderate refractive index: wamba CR-39 propylene diethylene glycol carbonate, refractive index ndi 1.497-1.504.Pakadali pano, chiwonetsero chapamwamba kwambiri cha ma lens a utomoni omwe amagulitsidwa pamsika wa magalasi a Shenyang ndi magalasi a resin ultra-woonda kwambiri, refraction Mlingo ukhoza kufika 1.67, ndipo tsopano pali ma lens a utomoni okhala ndi index ya 1.74.

C. Kulimba kwa pamwamba ndi kochepa kuposa galasi, ndipo ndikosavuta kukanda ndi zinthu zolimba.Choncho, iyenera kuumitsidwa.Zinthu zowumitsidwa ndi silika, koma kuuma kwake sikofanana ndi kuuma kwa galasi.Choncho, wovalayo ayenera kumvetsera lens.kukonza;

D. Kutanuka ndi kwabwino.Chifukwa cha danga pakati pa maunyolo a organic molekyulu, elasticity ndi 23-28 nthawi ya chidutswa cha galasi.Chikhalidwe china chachikulu cha pepala la utomoni chimatsimikiziridwa - kukana kukhudzidwa kwabwino.Mayiko a ku Ulaya, America, ndi Japan amaletsa ana osapitirira zaka 16 kuvala magalasi agalasi;

E. Ntchito Yothandizira: Itha kuwonjezeredwa kuti ipeze ntchito monga kuteteza kuwala koyipa ndi kusinthika.
