1.71 Magalasi a Single Vision HMC Optical
Lenzi ya 1.71 Dzina lonse la lenzi ya 1.71 refractive index, yokhala ndi refractive index yapamwamba, transmittance yayikulu, makhalidwe apamwamba a Abbe number, ngati ili ndi digiri yomweyo ya myopia, ingachepetse kwambiri makulidwe a lenzi, kuchepetsa ubwino wa lenzi, nthawi yomweyo, kupangitsa lenzi kukhala yoyera komanso yowala, yosasavuta kufalitsa tinthu ta utawaleza. Zapezeka kuti kuwonjezera cyclic sulfide resin mu zinthu za lenzi kungathandize kuti refractive index ya lenzi ikwere, koma cyclic sulfide resin yambiri ingayambitse kuchepa kwa transmittance ya kuwala ndi kusweka kwa zinthu. Mwa kuwongolera bwino kuchuluka kwa ring sulfure resin mu 1.71KR resin, lenzi ya 1.71 imapeza refractive index yayikulu ndi abbe number pamene ikutsimikizira kuti kuwala kumayenda bwino, kufalikira kochepa komanso kuwona bwino.

Magalasi owunikira a 1.56 a Porgressive HMC
Lenzi yotsogola ndi lenzi yokhala ndi ma focal length ambiri, yosiyana ndi magalasi owerengera achikhalidwe ndi magalasi owerengera a bifocal. Ma lenzi otsogola satopa chifukwa cha maso omwe amafunika kusintha nthawi zonse kutalika kwa focal pogwiritsa ntchito ma bifocal lengths, ndipo palibe mzere woonekeratu pakati pa mizere iwiri yolunjika. Ndi yabwino kuvala ndipo ili ndi mawonekedwe okongola, ndipo pang'onopang'ono yakhala chisankho chabwino kwambiri kwa anthu omwe ali ndi presbyopia.
