    Kutheni kufuneka ukhethe iilensi ze-CR-39 eziOptical?

    ICrystal Vision (CR) ziilensi ezikumgangatho ophezulu ezenziwe yenye yeenkampani ezinkulu zehlabathi.
    I-CR-39, okanye i-allyl diglycol carbonate (ADC), i-polymer yeplastiki esetyenziswa ngokuqhelekileyo ekwenzeni iilensi zeglasi.
    Isishunqulelo simele "iColumbia Resin #39", eyayiyifomula yama-39 yeplastiki yokubeka thermosetting eyaphuhliswa yiprojekthi yeColumbia Resins ngo-1940.
    Eyeye-PPG, le mathiriyeli iguqula ukwenziwa kweelensi.
    Isiqingatha sobunzima njengeglasi, mancinci kakhulu amathuba okuba sibe nokuqhekeka, kwaye umgangatho wokukhanya uphantse ulingane neglasi.
    I-CR-39 iyafudunyezwa kwaye igalelwe kwiimolds zeglasi ezisemgangathweni - ukulungelelanisa iimpawu zeglasi ngokusondeleyo kakhulu.

    Isibane esiBlue-Violet

    Olunye utshintsho olukhulu kukukhanya okuluhlaza.Ukukhanya okuluhlaza okwesibhakabhaka akukutsha - kuyinxalenye yembonakalo ebonakalayo.

    Ilanga ibingowona mthombo mkhulu wokukhanya okuluhlaza ukusukela ekuqaleni kwexesha kunye nokuvezwa ngaphandle ngokuphindwe ka-500 ngaphezu kwangaphakathi.Utshintsho ekukhanyeni okuluhlaza okwesibhakabhaka luza nolwazi lwethu ngempembelelo yalo kwindlela yokubona.Ngombulelo kuphando olwenziwa yiParis Vision Institute kunye ne-Essilor, ngoku siyazi ukuba ininzi yeehagu i-retinal cell ukufa kwenzeka xa ezi seli zibonakaliswe kwiibhanti zokukhanya eziluhlaza okwesibhakabhaka phakathi kwe-415nm-455nm, kunye nencopho ye-435nm.

    iilensi eziluhlaza okwesibhakabhaka

    Zeziphi izisombululo zamehlo esinazo zokunciphisa ukukhanya okuluhlaza okwesibhakabhaka?

    Ayizizo zonke izibane eziluhlaza ezingalunganga kuwe.Nangona kunjalo, ukuKhanya okuBlue okuyingozi kunjalo.

    Ikhutshwa kwizixhobo ezisetyenziswa zizigulana zakho yonke imihla-njengeekhompyuter, ii-smartphones kunye neetafile.

    Kwaye ekubeni i-60% yabantu ichitha ngaphezulu kweeyure ezintandathu ngosuku kwizixhobo zedijithali, izigulana zakho ziya kuba zibuza ukuba zingenza ntoni ukukhusela amehlo azo kolu tyhileko olude lwe-Harmful Blue Light.

    Izinto eziphambili zokuThatha

    • Ukukhanya okuluhlaza okwesibhakabhaka ukusuka kwi-415-455 nm kuye kwangqinwa njenge-oxidative inducer yoxinzelelo olunamandla kunye ne-inhibitor yokukhusela, ngoko ke enye yeendlela eziyingozi kakhulu zokukhanya kwi-retina.

    • Umngcipheko onokubakho onxulunyaniswa nokwanda kokuvezwa kokukhanya okuluhlaza okwesibhakabhaka unokuguqulwa ngenxa yobuchwepheshe bamva nje belensi yamehlo.

    • Imfundo yesigulana ibalulekile ukuphakamisa ulwazi malunga nemiphumo eyingozi yokukhanya okuluhlaza kunye nezisombululo ezikhoyo zokuthintela.

    • Isibane esiluhlaza okwesibhakabhaka senziwe ngobungozi (blue-violet) kunye nenzuzo (blue-turquoise) radiations.Kubalulekile ukuba ilensi ye-ophthalmic ibhloke eyokuqala kwaye idlule kweyamva.

    • Xa uthelekisa izisombululo ezahlukeneyo ze-optical zokucoca ukukhanya okuluhlaza okwesibhakabhaka kubalulekile ukukhumbula ukuba ayisiyiyo kuphela inani le-blue-violet ukukhanya okuvaliweyo kubalulekile kodwa kunye neebhanti ze-wavelength zivaliwe.

  • Ngaphambili:
  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
