Bifocal lens yog hais txog tib lub lens nrog ob lub diopters sib txawv, ob lub diopters
Nws muab faib rau ntau thaj chaw sib txawv ntawm lub lens. Thaj chaw rau pom deb hu ua thaj chaw telophotomic, uas nyob rau sab saud ntawm lub lens. Thaj chaw siv los saib ze hu ua thaj chaw pom ze thiab nyob rau hauv ib nrab qis ntawm lub lens.
Cov txiaj ntsig ntawm cov tsom iav bifocals: KOJ tuaj yeem pom cov khoom nyob deb kom meej meej los ntawm thaj chaw deb ntawm ib khub tsom iav, thiab koj tuaj yeem pom cov khoom nyob ze kom meej meej los ntawm thaj chaw ze ntawm tib khub tsom iav. Tsis tas yuav nqa ob khub tsom iav, tsis tas yuav hloov ntawm cov tsom iav deb thiab ze ntau zaus.

Cov iav PC qhov chaw yog ua los ntawm cov iav polycarbonate, thiab cov iav resin (CR-39) muaj qhov sib txawv tseem ceeb! PC feem ntau hu ua iav tiv taus mos txwv, yog li cov iav PC ua raws li cov yam ntxwv zoo ntawm cov khoom siv raw super impact resistance, thiab vim muaj cov ntsuas refractive siab thiab lub teeb yuag, txo qhov hnyav ntawm lub lens, muaj ntau qhov zoo xws li: 100% UV tiv thaiv, 3-5 xyoos yuav tsis daj. Yog tias tsis muaj teeb meem hauv cov txheej txheem, qhov hnyav yog 37% sib dua li cov ntawv resin ib txwm muaj, thiab qhov cuam tshuam tiv taus yog txog li 12 npaug ntawm cov resin ib txwm muaj!
