Kazhinji, magirazi ezuva ane zvinotevera zvinhu:
1. Resin lens Lens zvinhu: Resin chinhu chemakemikari chine phenolic chimiro. Zvimiro: huremu huremu, kupisa kwekushisa kwepamusoro, kupikisa kwakasimba, uye kunogona kuvharisa ultraviolet mwaranzi.
2. Nylon lens Lens material: yakagadzirwa nenylon, maitiro: yakanyanyisa elasticity, yakanakisa optical quality, yakasimba kukanganisa kupikisa, inowanzoshandiswa sezvinhu zvinodzivirira.
3. Carbonated polyester lens (PC lens) lens zvinhu: yakasimba, isiri nyore kuputsika, inopesana nemigumisiro, yakanyatsogadzirirwa lens zvinhu zvemagirazi emitambo, mutengo wakakwirira kudarika we acrylic lenses.
4. Acrylic lens (AC lens) lens material: Iine kusimba kwakanakisisa, kureruka, maonero akakwirira uye yakanaka anti-fog.
Production Sumo
Ophthalmologists vanokurudzira kuti unofanira kugara wakapfeka magirazi ezuva kudzivirira maziso ako; Izvi zvinodaro nekuti mboni yeziso redu (lenzi) iri nyore kwazvo kutora mwaranzi yeultraviolet, uye kukuvadzwa kwemwaranzi yeultraviolet kune maitiro maviri akatanhamara:
1.Kukuvadza kwemirairo ye ultraviolet kuchaunganidza. Sezvo ultraviolet chiedza chiri chiedza chisingaoneki, zvakaoma kuti vanhu vazvione intuitively.
2.Kukuvadza kwemirairo ye ultraviolet kumaziso hakugoneki, kureva, haigadziriswi. Zvakadai se: kuvhiyiwa kwecataract kunogona kungotsiviwa ne-intraocular lenses. Kukuvadzwa kwenguva refu kweziso kunogona kutungamira kukuvadzwa kwe cornea uye retina, kuvharika kwe lens kusvika cataract yaitika, zvichikonzera kukuvara kwekusingaperi kwekuona.
Sezvo kukuvadzwa kwemirairo ye ultraviolet kumaziso kusingaoneki, haigoni kunzwika pakarepo. Kana iwe usingapfeki magirazi, haunzwe kunyanya kugadzikana. Zvinongoreva kuti maziso ako haanyanyi kutarisisa kuchiedza chinooneka (sekupenya kupenya, kupenya, uye kupenya kwechiedza). , uye haigone kudzivirira kukuvara kweUV.
Ko kusviba kwemagirazi ezuva, ndiko kuri nani kuvharisa UV?
Kwete, basa re lens rekuvhara ultraviolet rays nderokuti rinobatwa nemaitiro anokosha (kuwedzera UV powder) panguva yekugadzira, kuitira kuti lens inogona kutora chiedza chinokuvadza pasi pe400NM se ultraviolet rays apo chiedza chinopinda. Izvo hazvina chekuita nekudzika kwefirimu.
