Sibhekisela ekukhanyeni okubonwa liliso lomntu njengokukhanya okubonakalayo, oko kukuthi, "i-orenji ebomvu e-orenji eluhlaza okwesibhakabhaka eluhlaza okwesibhakabhaka".
Ngokwemigangatho emininzi yelizwe, ukukhanya okubonakalayo kuluhlu lwe-wavelength ye-400-500 nm kubizwa ngokuba kukukhanya okuluhlaza okwesibhakabhaka, olona bude bufutshane kunye nokukhanya okunamandla (HEV) ekukhanyeni okubonakalayo.
Ukukhanya okuluhlaza okwesibhakabhaka kukho yonke indawo ebomini bethu.Ukukhanya kwelanga ngowona mthombo wokukhanya okuluhlaza okwesibhakabhaka, kodwa imithombo emininzi yokukhanya eyenziweyo, efana nezibane ze-LED, i-TVS yeskrini esicaba kunye nezikrini zokubonisa idijithali ezifana neekhompyutha kunye neefowuni eziphathwayo, nazo zikhupha ukukhanya okuluhlaza okwesibhakabhaka.
Kuyaphawuleka ukuba nangona i-HEV ekhutshwa zezi zixhobo incinane xa ithelekiswa neyo ekhutshwa lilanga, ixesha abantu abalichitha kwezi zixhobo zedijithali liphezulu kakhulu kunexesha abalichitha elangeni.
Ukukhanya okuluhlaza okwesibhakabhaka kunokuba kubi okanye kulunge kuthi, kuxhomekeke kwixesha lokuvezwa, ukuqina, uluhlu lwamaza kunye nobude bokuvezwa.
Okwangoku, iziphumo zovavanyo ezaziwayo zonke zikholelwa ukuba eyona nto iyingozi kwiliso lomntu kukukhanya okuluhlaza okwesibhakabhaka okufutshane phakathi kwe-415-445nm, i-irradiation yexesha elide, iya kubangela umonakalo othile kwiliso lomntu;Ukukhanya okuluhlaza okude okuluhlaza ngaphezulu kwe-445nm akunabungozi nje emehlweni abantu, kodwa kukwadlala indima ebaluleke kakhulu kwisingqi sebhayoloji.
Ke ngoko, ukukhuselwa kokukhanya okuluhlaza kufuneka kube "chanekile", kuthintele ukukhanya okuluhlaza okuyingozi kunye nokuvumela ukukhanya okuluhlaza okwesibhakabhaka kungene.
Iiglasi ezikhanyayo ezichasene nombala oluhlaza okwesibhakabhaka ukusuka kuhlobo lokuqala lwe-substrate yokufunxa (i-tan lens) lens ukuya kuhlobo lokubonisa ifilimu, oko kukuthi, ukusetyenziswa kongqimba lwefilimu ukubonakalisa inxalenye yokukhanya okuluhlaza okwesibhakabhaka ngaphandle, kodwa ukubonakaliswa komphezulu we-lens kubonakala ngakumbi;Emva koko ukuya kuhlobo olutsha lwelensi engenambala yangasemva kunye nokuhanjiswa kokukhanya okuphezulu, iimveliso ezichasene neeglasi zeblue ray nazo zihlaziywa rhoqo kwaye ziphindaphindwa.
Ngeli xesha, imakethi yavela amanye amaso eentlanzi axubeneyo, iimveliso ezimdaka.
Ngokomzekelo, amanye amashishini e-intanethi athengisa iiglasi ze-blue-blocking zonyango kubathengi abaqhelekileyo.Ezi glasi zisetyenziselwa izigulana ezifunyaniswe zinesifo semacular okanye ezinye izigulana ezichacha kuqhaqho lwamehlo, kodwa zithengiswa njenge "100% blue-blocking".
Olu hlobo lweglasi ezichasene ne-blue blue, umbala ongasemva we-lens uphuzi kakhulu, umbono uya kuphazamiseka, ukuhanjiswa kuphantsi kakhulu kodwa kwandisa umngcipheko wokukhathala okubonakalayo;Izinga lokuthintela ukukhanya okuluhlaza liphezulu kakhulu ukuvala ukukhanya okuluhlaza okunenzuzo.
Ke ngoko, abantu akufuneki baphazame "ngemveliso elungileyo" ngenxa yeleyibhile "yezonyango".
Ukuze kuqinisekiswe ukusebenza kunye nomgangatho weemveliso zokukhusela i-blu-ray, ngoJulayi 2020, umgangatho ofanelekileyo "i-GB/T 38120-2019 ifilimu yokukhusela i-Blu-ray, impilo elula kunye nesicelo sokhuseleko olulula iimfuno zobuchwepheshe" zenzelwe iimveliso zokukhusela i-blu-ray.
Ke, xa wonke umntu EKHETHA UKUTHINTELA iiglasi eziluhlaza okwesibhakabhaka, kufuneka ajonge umgangatho wesizwe.
