Progressive multifocal lens
Iyo yakawanda yekutarisa lens, lens yepamusoro curvature kubva kumusoro kusvika kuzasi isati yaramba ichiwedzera, refractive simba kubva mudunhu riri munzvimbo yepamusoro yelens iri kure ne, zvishoma nezvishoma, yakawedzera zvichienderera, kusvika kunenge kuzasi kwelens ine nzvimbo. yakasvika nhamba inenge ne diopta, magirazi maviri anogona kuona, chinhambwe chinogona kuona pedyo zvakare, unogona zvakare kuona chinhu chinhambwe. Malenzi anofambira mberi anotsanangurwa se "lenzi anosimudza," uye magirazi maviri anogona kushandiswa semamwe magirazi. Semuenzaniso, yakakodzera kuti vadzidzi vaverenge nekunyora vadzidzi vanoshandisa lens (kusangana kutarisa pabhodhi, kuverenga mabhuku, basa rechikoro uye zvimwe zvinoonekwa zvinodiwa), yakakodzera kune chena-collar boka revanhu kuneta kwelens (kuenderana ne kure, pakati uye pedyo nekuona chinja, nyore kushanda), kuchinjira kune vepakati-vakwegura uye vanhu vakuru d optimal kufambira mberi lenzi (yemahara tsika curved pamusoro, zvakanaka, pakati, pedyo chinja, kwete dzungu uropi kuwedzera).
Production Sumo
Iyo mainstream refractive index ye lens inosanganisira: 1.56, 1.60, 1.67, 1.71, 1.74 zvichingodaro. Iyo yakakwirira iyo refractive index ye lens, iyo yakaonda uye yakareruka lens. Nekudaro, iyo yakakwirira iyo refractive index ye lens iri, zviri nani zviri nani. Kazhinji, iyo yakakwirira iyo refractive index ye lens ndeye, iyo yakaderera nhamba yeAbbe uye zvakanyanya kujeka kupararira kuri.
