    Vim li cas thiaj xaiv CR-39 Optical Lenses?

    Crystal Vision (CR) yog cov lo ntsiab muag zoo tshaj plaws ua los ntawm ib lub tuam txhab loj tshaj plaws hauv ntiaj teb.
    CR-39, los yog allyl diglycol carbonate (ADC), yog cov yas polymer feem ntau siv los tsim cov tsom iav qhov muag.
    Cov ntawv luv luv yog "Columbia Resin #39", uas yog 39th qauv ntawm cov yas thermosetting tsim los ntawm Columbia Resins project hauv xyoo 1940.
    Muaj los ntawm PPG, cov khoom siv no yog revolutionizing lens ua.
    Ib nrab hnyav li iav, tsis tshua muaj kev tawg, thiab kho qhov muag zoo yuav luag zoo li iav.
