A. Low density: nekuda kwemukana uripo pakati pecheni dzemamorekuru, huwandu hwemamorekuru pavhoriyamu yeyuniti idiki, iyo inotaridza zvakanakira resin lens: yakaderera chaiyo giravhiti uye chiedza magadzirirwo, ayo ari 1/3-1/2 ye girazi lens;
B. Moderate refractive index: yakajairika CR-39 propylene diethylene glycol carbonate, refractive index is 1.497-1.504.Parizvino, iyo yepamusoro refractive index ye resin lenses inotengeswa pamusika weShenyang magirazi is aspherical ultra-thin hardened film resin lens, refraction The rate inogona kusvika 1.67, uye ikozvino kune resin lenses ine refractive index ye1.74.
C. Kuoma kwepamusoro kwakadzikira pane kwegirazi, uye zviri nyore kukweshwa nezvinhu zvakaoma.Nokudaro, inoda kuomeswa.Iyo yakaomeswa zvinhu ndeye silica, asi kuomarara hakuna kunaka sekuoma kwegirazi.Nokudaro, muchengeti anofanira kutarisisa kune lens.kuchengetedza;
D. The elasticity yakanaka.Nekuda kwenzvimbo iri pakati peiyo organic molecular cheni, iyo elasticity ndeye 23-28 nguva iyo yegirazi chidimbu.Humwe hunhu hukuru hweshizha resin yakatemwa - yakanaka kukanganisa kupikisa.Nyika dzeEurope, America, uye Japan dzinorambidza vana vari pasi pemakore gumi nematanhatu kupfeka magirazi egirazi;
E. Auxiliary basa: Inogona kuwedzerwa kuwana mabasa akadai sekudzivirira mwaranzi inokuvadza uye kubuda kwemavara.
