    No ke aha e koho ai i nā Lenses Optical CR-39?

    ʻO Crystal Vision (CR) nā lens maikaʻi loa i hana ʻia e kekahi o nā hui lens nui loa o ka honua.
    ʻO CR-39, a i ʻole allyl diglycol carbonate (ADC), he polimer plastik i hoʻohana mau ʻia i ka hana ʻana i nā aniani aniani.
    ʻO ka pōkole no "Columbia Resin #39", ʻo ia ka 39th formula o kahi plastic thermosetting i hoʻomohala ʻia e ka Columbia Resins project ma 1940.
    Loaʻa iā PPG, ke hoʻololi nei kēia mea i ka hana lens.
    ʻO ka hapalua ke kaumaha e like me ke aniani, ʻaʻole hiki ke haki, a ʻoi aku ka maikaʻi o ke aniani.
    Hoʻomaʻamaʻa ʻia ʻo CR-39 a ninini ʻia i loko o nā pahu aniani ʻano maikaʻi - hoʻololi pono i nā ʻano o ke aniani.

    ʻO kekahi hoʻololi nui he kukui uliuli.ʻAʻole hou ke kukui uliuli - he ʻāpana ia o ka spectra ʻike ʻia.

    ʻO ka lā ke kumu nui loa o ke kukui polū mai ka hoʻomaka ʻana o ka manawa me ka ʻike ʻana i waho he 500 mau manawa ʻoi aku ka nui ma mua o ka hale.ʻO ka hoʻololiʻana i ke kukui uliuli e hele mai me ko mākouʻike i kona hopena ma ka'ōnaehanaʻike.Mahalo i ka noiʻi i hana ʻia e ka Paris Vision Institute a me Essilor, ʻike mākou i kēia manawa ʻo ka hapa nui o nā puaʻa retinal cell make i ka wā e ʻike ʻia ai kēia mau cell i nā kaula kukui uliuli-violet ma waena o 415nm-455nm, me kahi kiʻekiʻe ma 435nm.

    He aha nā hāʻina optical e hōʻemi ai i ke kukui polū?

    ʻAʻole maikaʻi nā kukui uliuli a pau iā ʻoe.Eia naʻe, ʻo Harmful Blue Light.

    Hoʻokuʻu ʻia ia mai nā hāmeʻa a kāu poʻe maʻi e hoʻohana ai i kēlā me kēia lā-e like me nā kamepiula, smartphones, a me nā papa.

    Nā mea lawe nui

    • Uaʻikeʻia ke kukui polū-violet mai ka 415-455 nm ma keʻano he mea hoʻoulu koʻikoʻi oxidative ikaika a he mea pale pale, no laila kekahi o nāʻano māmāʻoi loa o ka pōʻino no ka retina.

    • Hiki ke ho'ololi 'ia ka pilikia e pili ana i ka ho'onui 'ana i ke kukui polū ma muli o ka 'enehana lens ophthalmic hou loa.

    • He mea koʻikoʻi ka hoʻonaʻauao ʻana i nā mea maʻi e hoʻonui i ka ʻike e pili ana i nā hopena ʻino o ke kukui polū a me nā hoʻonā pale.

    • Hoʻokumu ʻia ke kukui ʻulaʻula me nā radiation pōʻino (blue-violet) a me ka pono (blue-turquoise).He mea pono e hoʻopaʻa ka lens ophthalmic i ka mua a hoʻokuʻu i ka hope.

    • I ka hoʻohālikelike ʻana i nā ʻoluʻolu ʻokoʻa no ka kānana kukui polū, pono e hoʻomanaʻo ʻaʻole ʻo ka nui o nā kukui uliuli-violet i pale ʻia he mea nui akā ua pale pū ʻia nā kaula lōʻihi.
