Sibhekisela ekukhanyeni iso lomuntu elingakubona njengokukhanya okubonakalayo, okungukuthi, "okubomvu okuwolintshi okuphuzi okuluhlaza okwesibhakabhaka okunsomi okwesibhakabhaka".
Ngokwamazinga amaningi kazwelonke, ukukhanya okubonakalayo ebangeni le-wavelength elingu-400-500 nm kubizwa ngokukhanya okuluhlaza okwesibhakabhaka, okuwubude obufushane kakhulu beza nokukhanya okunamandla kakhulu (HEV) ekukhanyeni okubonakalayo.


Ukukhanya okuluhlaza okwesibhakabhaka kukhona yonke indawo ezimpilweni zethu.Ukukhanya kwelanga kuwumthombo oyinhloko wokukhanya okuluhlaza okwesibhakabhaka, kodwa imithombo eminingi yokukhanya yokwenziwa, njengezibani ze-LED, i-TVS yesikrini esiyisicaba kanye nezikrini zokubonisa ezidijithali ezifana namakhompyutha nomakhalekhukhwini, nazo zikhipha ukukhanya okuningi okuluhlaza okwesibhakabhaka.
Kuyaphawuleka ukuthi nakuba i-HEV ekhishwa yile mishini incane uma iqhathaniswa naleyo ekhishwa yilanga, isikhathi abantu abasichitha kule mishini yedijithali sikhulu kakhulu kunesikhathi abachayeka ngaso elangeni.

Ukukhanya okuluhlaza kungaba kubi noma kube kuhle kithi, kuye ngesikhathi sokuchayeka, ukuqina, ububanzi be-wavelength kanye nobude bokuchayeka.
Njengamanje, imiphumela yokuhlola eyaziwayo yonke ikholelwa ukuthi okuyinhloko okuyingozi esweni lomuntu ukukhanya okuluhlaza okwesibhakabhaka kwe-short-wave phakathi kuka-415-445nm, imisebe yesikhathi eside ehlanganisayo, kuzodala umonakalo othile wokubona iso lomuntu;I-wavelength ende yokukhanya okuluhlaza ngaphezu kuka-445nm ayithina nje ingozi emehlweni abantu, kodwa futhi idlala indima ebaluleke kakhulu kusigqi sebhayoloji.


Ngakho-ke, ukuvikelwa kokukhanya okuluhlaza kufanele kube "okunembile", kuvimbele ukukhanya okuluhlaza okulimazayo futhi kuvumele ukukhanya okuluhlaza okwesibhakabhaka okuzuzisayo kudlule.

Izibuko ezikhanyayo eziluhlaza okwesibhakabhaka ezisuka ohlotsheni lokuqala lokumuncwa kwe-substrate (i-tan lens) ukuya ohlotsheni lokubonisa ifilimu, okungukuthi, ukusetshenziswa kongqimba lwefilimu ukukhombisa ingxenye yokukhanya okuluhlaza okwesibhakabhaka ngaphandle, kodwa ukubonakaliswa kwe-lens kusobala kakhulu;Bese kuthi ohlotsheni olusha lwelensi engenawo umbala wangemuva kanye nokudluliswa kokukhanya okuphezulu, imikhiqizo ye-anti-glass ye-blue ray nayo ibuyekezwa njalo futhi iphindwe.

Ngalesi sikhathi, imakethe ibuye yavela ubuhlalu obuxubene neso lezinhlanzi, imikhiqizo engaqinile.
Isibonelo, amanye amabhizinisi aku-inthanethi athengisa izibuko zokuvimbela eziluhlaza okwesibhakabhaka kubathengi abajwayelekile.Lezi zibuko ekuqaleni zisetshenziselwa iziguli ezitholakale zine-macular disease noma ezinye iziguli ezilulama ekuhlinzweni kwamehlo, kodwa zithengiswa ngokuthi "100% blue-blocking".
Lolu hlobo lwezibuko ezikhanyayo eziphikisana nohlaza okwesibhakabhaka, umbala wangemuva welensi uphuzi kakhulu, umbono uzohlanekezelwa, indlela yokudlulisela iphansi kakhulu kodwa ibhebhethekisa ingozi yokukhathala okubukwayo;Izinga lokuvimbela ukukhanya okuluhlaza okwesibhakabhaka liphezulu kakhulu ukuvimba ukukhanya okuluhlaza okuzuzisayo.
Ngakho-ke, abantu akufanele baphazanyiswe "ngomkhiqizo omuhle" ngenxa yelebula "yezokwelapha".
Ukuze kuqinisekiswe ukusebenza nekhwalithi yemikhiqizo yokuvikela i-blu-ray, ngoJulayi 2020, indinganiso efanele ethi "GB/T 38120-2019 Blu-ray film protection, impilo elula kanye nezimfuneko zobuchwepheshe zohlelo lokuphepha olukhanyayo" kwakheka imikhiqizo yokuvikela i-blu-ray.
Ngakho-ke, lapho wonke umuntu EKHETHA UKUVIMBELA izibuko ezikhanyayo eziluhlaza okwesibhakabhaka, kufanele abheke izinga likazwelonke.
