CR39(1.50 refractive index):CR39 inoratidzwa nehupamhi hweAbbe nhamba, kujeka kwepamusoro, kupikisa kwakasimba kupfeka (pasina kuvhara), kuderera kwepasi (inenge hafu pasi pegirazi lens), kushanda kwakanaka kwekudhaya, kupikisa kunyungudutsa, makemikari kuramba uye kupisa kupisa.Uye nekuti maitiro ekugadzira akakura, mutengo wakaderera, kusvika zvino ichiri chimwe chezvinhu zvakakurumbira muindasitiri yelens.Nekudaro, CR39 haina brittle pane zvimwe zvinhu maererano nekukanganisa kupikisa uye kusimba kwesimba, saka haikodzeri magirazi asina rimless (lenses anowanzo tyoka kana akaboorwa), uye zvakare ine yakaderera refractive index, ichiita kuti malenzi akobvu pamadhigirii epamusoro.

1.56 Refractive index:Iyo mbishi inowanzo NK55, iyo inowanzonzi acrylic.Mutengo wacho wakaderera uye chiyero chekushandisa chakakwira, asi pfungwa yechiedza haina simba.Iyo lenzi ine brittle, uye iri nyore kutyora kana uchiboora furemu.

1.59 PC zvinhu:PC zvinhu iPolycarbonate, iri thermoplastic purasitiki ine refractive index ye1.59 uye yakasimba kukanganisa kuramba.Inogona kushandiswa semagirazi asingapindi bara uye ngowani mumunda wemauto.Inogona kushandiswa mumagirazi pasina kunetseka pamusoro pekuputsika kwema lenses.Inokodzera magirazi asina rimless.Uye iyo refractive index yakakwira kupfuura CR39, iyo lens inogona kuitwa yakatetepa.Asi sechinhu che thermoplastic, kuita kwayo kugadzirisa uye kuramba kwemakemikari hakuna kunaka, kwete yakavharwa pamusoro zvakare iri nyore kukwenya, kupfeka kuramba.Mukuwedzera, nhamba yayo yeAbbe imakumi matatu, iyo 28 yakasiyana neCR39.

MR zvinhu (1.60MR-8, 1.67MR-7, 1.74MR-174):MR™ inoteedzana yepakati uye yakakwirira refractive index resin zvinhu zvakagadziriswa neMitsui Chemical Company muJapan.Kunze kweMR174, iyo yese nhevedzano yakagadzirwa ne polyurethane zvinhu (MR174 iring sarufa zvinhu zvine nani kupararira kuramba).Kunyangwe iyo kukanganisa kupikisa haina kunaka sePC uye Trivex, ine mabhenefiti ari pachena pamusoro peCR39.Pamusoro pezvo, nhamba yeabbe yeiyi nhevedzano yezvishandiso ine mwero, kupisa kupisa, kusamira kwemamiriro ekunze uye makemikari kuramba kwakanaka, saka ine yakanaka yakazara mashandiro.
