1、Zvishandiso uye Categories
Panyaya yezvinyorwa, inogona kukamurwa kuita mana marudzi: girazi, PC, resin uye echisikigo lenzi.Inonyanya kushandiswa ndeye resin.
Spherical uye aspherical: kunyanya kutaura nezve aspherical lenses, mukana weaspherical lenzi ndeyekuti iyo lens mupendero kukanganisa idiki.
Nenzira iyi, lens ine mufananidzo wakanaka, hapana kukanganisa, uye munda wakajeka wekuona.
Uye pasi pechinhu chimwe chete uye dhigirii, aspherical lenses akapfava uye akatetepa kupfuura spherical lenzi.
Madhigirii uye Refractive Index
Kazhinji kutaura, zvinokurudzirwa kusarudza lens ine high refractive index.Iyo yakakwirira iyo refractive index, iyo yakaonda iyo lens.
Asi teerera kune dambudziko, ndiko kuti, iyo yakakwira iyo refractive index, kukanganisa kwenhamba yeAbbe, usaite upofu kutevedzera refractive index, yakananga ongororo yematambudziko chaiwo.
2、Abbe nhamba uye kupfeka
Iyo inonzi Abbe coefficient, iyo inozivikanwawo seyekuparadzira coefficient, inowanzonzi kumucheto kwemagirazi kuona chinhu chiri pedyo neziso remunhu pasina pepuru yepepuru, yero edge uye yebhuruu.Kazhinji kutaura, iyo yakakura iyo refractive index yepakati, iyo yakanyanya kupararira kupararira, ndiko kuti, yakaderera nhamba yeAbbe.Izvi zvinopindurawo chikonzero nei zvichitaurwa pamusoro kuti iyo refractive index haifanirwe kuteverwa neupofu.
(Gohodza pabhodhi: The same medium optical medium ine siyana refractive indices yeavelengths akasiyana echiedza. Semuyenzaniso, kupenya kwechiedza chezuva kuburikidza neprism kunoratidza mavara manomwe echiedza, chinova chiitiko chekupararira.)
Tevere, ngatitaure nezve kupfekedzwa kwe lens.Lens yakanaka ichava nemateru akati wandei ekuputira.
Iyo yepamusoro mold haipindi mvura uye inodzivirira mafuta;iyo anti-reflection firimu inoita kuti chiedza chiwedzere mukati:
Iyo electrostatic discharge firimu inoita kuti guruva risave nyore kutora;iyo yakaoma firimu inogona kuchengetedza lens uye kuita kuti zvisave nyore kukweshwa uye zvichingodaro.
3、Inoshanda lenzi
Kutaura chokwadi, nezve mashandiro emalenzi.
Ndakafungawo kuti zvakanga zvisingatsananguriki kare, iyo lens haisi yekubatsira myopia kuona zvinhu zvakajeka, mabasa akawanda anobva kupi?Kunyanya, ini ndinongoziva kuti kune lenzi ane anti-blue mwenje, kusvika mushure mekunge ndatarisa ruzivo rwakawanda (Tenzi, ndakaona!)
Zvinoitika kuti ine zvikamu zvakawanda!(Kunyange ndisingachazvirangariri mushure mekuiverenga)
Zvisinei, nokuda kwekunzwisisa kwechinyorwa, zvakasarudzwa kuti zvigadziriswe.
A Anti-blue light lens:Izvi hazvidi kuunzwa zvakanyanya.Sezvinoratidzwa nezita racho, inogona kuita basa rekudzivirira-blue light.Inonyanya kukodzera kune shamwari dzinowanzotarisa mafoni nemakombiyuta.
B Inofambira mberi multifocal lens:Rudzi urwu rwelenzi zvinoreva kuti kune akawanda anotarisisa mapoinzi pane imwe lenzi, uye zvinhu zviri madaro akasiyana zvinogona kuoneka zvakajeka neshanduko yenzvimbo yekuona.Kureva kuti, lenzi iyi inogona kuve nekupenya kwakasiyana kunodiwa kuti uone chinhambwe chakareba, chinhambwe chepakati uye chinhambwe chepedyo panguva imwe chete.
- Ine zvikamu zvitatu:
- firimu rinofambira mberi rezera repakati nepakati (magirazi ekuverenga): Iri rinofanira kunge riri iro rinonyanya kuzivikanwa.Inokodzera zvose myopia uye presbyopia.
- Adolescent myopia control lens - anoshandiswa kuderedza kuneta kwekuona uye kudzora kukurumidza kwekukura kwemyopia.Iyo "mudzidzi akanaka" lenzi ndeimwe yakadaro.
- b Adult anti-fatigue lenses - yevagadziri uye dzimwe shamwari dzinowanzotarisana nemakombiyuta.Mune mamwe mazwi, mazhinji emanzwiro ndeekunyaradza mupfungwa chete.Chinhu chinonyanya kukosha ndechekubatanidza basa nekuzorora, uye kutora zororo rakakodzera.
- c Akangwara anoshandura mavara lenzi.Kana wasangana nechiedza che ultraviolet chakasimba, chinozongosviba uye chinovharira mwenje wakasimba we ultraviolet kunze.Kana uchidzokera kunzvimbo ine rima yakaita semukati memba, inongozopenya kuti ive nechokwadi chekujeka kwechiratidzo.
