Ndezvipi zvinofambira mberi uye zvekunze zvinofambira mberi?
Outer Progressives
Iyo yekunze inofambira mberi lenzi inodaidzwa zvakare kuti iyo yepamberi dhizaini inofambira mberi lens, iyo ndiyo simba gradient nzvimbo inoiswa pamberi pechiso chelens, kure kure nemeso.
Inner Progressives
Inner inofambira mberi inozivikanwawo seyekumashure dhizaini inofambira mberi lens, iyi mhando yeinofambira mberi lens inoreva kushandiswa kwemahara fomu yepamusoro tekinoroji uye lathe yekugadzirisa michina yekuisa iyo degree gradient dhizaini (inoshanda nzvimbo) kumashure, iri padyo nemeso.
Musiyano wekugadzira pakati pekufambira mberi kwemukati uye kunze kunofambira mberi
Outer progressivelenzi dzinogadzirwa uchishandisa musanganiswa wenzira mbiri dzekugadzirisa.
1. Kutanga kugadzirisa
Iyo ADD uye corridor kureba kwekunze kwekunze kwakagadzirwa pamberi pechiso mold ye lens, uye mold iri kumashure kweiyo lens haina shanduko mune photometric curvature.Iyo lens substrate ine ADD inogadzirwa nemhando mbiri dzinoshandisa mutsara wegungano, iyo yakatsaurirwa kune anofambira mberi lenzi.Substrate, kwete yekushandiswa mukugadzirwa kwemamwe marudzi emalenzi.Kazhinji kugadzirwa kwema substrates akadaro kunoda kuenderana neADD yega yega, saka dura rekuchengetedza rema substrates rakakura.
2. Secondary processing
Kubva pamasheya emalenzi anogadzirwa nekutanga kugadzirisa, tsvaga maUC lenzi ane inodiwa ADD, uye woigadzira kuseri kwechiso chelens kuti uwane simba riri kure.Mushure meaya matanho maviri ekugadzirisa, maviri einofambira mberi lenzi anopedzwa.
Inner progressive, nzvimbo yaro ye gradient iri panzvimbo yemukati ye lens, uye pakati payo inowanikwawo mukati memukati we lens.Nzvimbo yayo yekunze inotora yakafanana spherical kana aspheric dhizaini seyakajairwa ega ekuona lenzi.
Yakasiyana neyechinyakare yekugadzirisa tekinoroji, iyo yemahara-fomu yemukati inofambira mberi lens inogona kugadzirwa zvinoenderana nekumisikidzwa kwechirongwa chekombuta, uye kutora yakasanganiswa yekuumba dhizaini.Nerubatsiro rwe "soft polishing" yekugadzira tekinoroji, iyo yepamusoro-yemhando yedhijitari yekushandura nzira yekumashure kweiyo lens inogona kuchengetedzwa zvachose.Iyo yepakutanga inofambira mberi dhizaini.
