    Sei Kusarudza CR-39 Optical Lenses?

    Crystal Vision (CR) ndiwo emhando yepamusoro lenzi akagadzirwa neimwe yepasirese lenzi kambani.
    CR-39, kana allyl diglycol carbonate (ADC), ipurasitiki polima inowanzoshandiswa mukugadzira lenzi dzemaziso.
    Ichi chipfupi chinomiririra "Columbia Resin #39", yaive fomula yechimakumi matatu nepfumbamwe yepurasitiki yekupisa yakagadziridzwa neColumbia Resins chirongwa muna 1940.
    Inove yePPG, chinhu ichi chiri kushandura kugadzirwa kwemalenzi.
    Hafu inorema segirazi, kashoma kuti ipwanyika, uye kunaka kwemaziso kwakada kuita segirazi.
    CR-39 inodziya uye inodururwa mumhando yegirazi molds - kugadzirisa hunhu hwegirazi zvakanyanya.

    Key Takeaways

    • Chiedza cheBlue-violet kubva ku415-455 nm chakaratidzwa sechinhu chakasimba che oxidative stress inducer uye kudzivirira inhibitor, saka imwe yenzira dzinokuvadza dzechiedza che retina.

    • Njodzi inogona kuitika yakabatana nekuwedzera kuratidzwa kwechiedza chebhuruu inogona kugadziridzwa nekuda kwechizvino-zvino tekinoroji yemaziso.

    • Dzidzo yevarwere yakakosha kusimudza ruzivo pamusoro pezvose zvinokuvadza zvechiedza chebhuruu uye zvigadziriso zvekudzivirira zviripo.

    • Chiedza chebhuruu chinoumbwa nekukuvadza (blue-violet) uye inobatsira (blue-turquoise) radiations. Izvo zvakakosha kuti ophthalmic lens inovharira yekutanga uye inoregedza kupfuura iyo yekupedzisira.

    • Kana uchienzanisa zvakasiyana-siyana optical solutions for blue light filtering zvakakosha kuchengeta mupfungwa kuti kwete chete chiyero chebhuruu-violet chiedza chakavharwa chakakosha asiwo mabhendi ewavelength akavharwa.
