1. Kuyini Ukukhanya Okuluhlaza okwesibhakabhaka?
Amehlo ethu angabona umhlaba onemibala kangaka, owakhiwe kakhulu ngemibala eyisikhombisa ebomvu, e-orenji, ephuzi, eluhlaza okotshani, e-cyan, eluhlaza okwesibhakabhaka kanye ne-purple. Ukukhanya okuluhlaza okwesibhakabhaka kungenye yazo. Ngokwesiko, ukukhanya okuluhlaza okwesibhakabhaka uhlobo lokukhanya okubonakalayo olunobude be-wavelength obuphakathi kuka-380nm-500nm ngokwemvelo, okuhlukaniswe ngokukhanya okuluhlaza okwesibhakabhaka okuyingozi kanye nokukhanya okuluhlaza okwesibhakabhaka okuzuzisayo.
Ukukhanya Okuluhlaza Okwesibhakabhaka Okuyingozi
Phakathi kwazo, izifundo zikhombisile ukuthi ukukhanya okuluhlaza okwesibhakabhaka okunobude be-wavelength obuphakathi kuka-380nm no-450nm kuyingozi kubantu. Kungangena ku-cornea kanye nelensi, kwandise inani lobuthi endaweni ye-macular yeso, futhi kusongele kakhulu impilo yamehlo ethu. Imithombo eyinhloko imithombo yokukhanya ye-LED, omakhalekhukhwini, ama-ipad, amakhompyutha, ama-LCD monitors kanye neminye imikhiqizo kagesi. Esikhathini solwazi, sivame ukubhekana namafoni namakhompyutha, futhi ngokungenakugwenywa sibhekene nokukhanya okuluhlaza okwesibhakabhaka okuyingozi.

Esikhathini solwazi, sivame ukubhekana namafoni namakhompyutha, futhi ngokungenakugwenywa sibhekene nokukhanya okuluhlaza okwesibhakabhaka okuyingozi.
2. Umgomo Wezibuko Ezikhanyayo Ezingaluphuzi?
Cishe wonke umuntu usevele uyazi ukuthi kuyini ukukhanya okuluhlaza okwesibhakabhaka. Ake sixoxe ngesimiso sezibuko zokukhanya ezimelana nokukhanya okuluhlaza okwesibhakabhaka. Kunezinhlobo ezimbili zezibuko zokukhanya ezimelana nokukhanya okuluhlaza okwesibhakabhaka emakethe, ibhlogo lokukhanya eliluhlaza okwesibhakabhaka eliyi-monomer kanye nebhloko lokukhanya eliluhlaza okwesibhakabhaka elimbozwayo.
Ibhulokhi Lokukhanya Eliluhlaza okwesibhakabhaka le-Monomer
Enye iwukufaka isici sokukhanya esimelana nokuluhlaza okwesibhakabhaka ezintweni eziyisisekelo zelensi ukuze kutholakale ukukhanya okuluhlaza okwesibhakabhaka okuyingozi, ngaleyo ndlela kuqapheleke ukuthi ukukhanya okuluhlaza okwesibhakabhaka okuyingozi kuyavinjelwa. Umbala wamalensi alolu hlobo lwezibuko ngokuvamile uphuzi oluhlaza okwesibhakabhaka, osetshenziselwa ukunciphisa ukukhanya okuluhlaza okwesibhakabhaka.
Ibhulokhi Yokukhanya Okuluhlaza okwesibhakabhaka
Esinye ukuthi ukukhanya okuluhlaza okwesibhakabhaka okuyingozi kubonakala kakhulu ngengubo ebusweni belensi, elula futhi eqondile. Lolu hlobo lwezibuko aluhlukile kakhulu ezingilazini ezivamile ezibonakalayo. Umbala belensi ubonakala kahle, futhi uzoba phuzi kancane.
3. Ingabe Kuyadingeka Ukuthenga Izingilazi Ezikhanyayo Ezingaluphuzi?
Abantu ababizwa ngokuthi izinkulungwane zabantu kanye nobuso obuyizinkulungwane, isimo sabo bonke sihlukile, akuwona wonke umuntu ofanelekela izibuko eziluhlaza okwesibhakabhaka, ukuthenga okungaboni kuzolimaza, ngifingqe izinhlobo eziningana zabantu abafanelekela ukusebenzisa izibuko eziluhlaza okwesibhakabhaka kanye nalabo abangafanelekeli izibuko eziluhlaza okwesibhakabhaka njengereferensi yakho. Ngemva kokuyifunda, uzokwazi ukuthi udinga yini ukuthenga izibuko eziluhlaza okwesibhakabhaka.
Kufanelekela Izibuko Ezikhanyayo Eziluhlaza okwesibhakabhaka
1). Abantu abadlala omakhalekhukhwini isikhathi eside noma abasebenza ezikrinini zekhompyutha isikhathi eside
Ukukhanya okuluhlaza okwesibhakabhaka okuyingozi ngokwako kuvela kakhulu emikhiqizweni kagesi efana namafoni aphathwayo namakhompyutha. Namuhla, izisebenzi ze-inthanethi zibuka isikrini sekhompyutha usuku lonke, futhi izibuko zazo zomile futhi azikhululekile. Izibuko zokukhanya ezilwa noluhlaza okwesibhakabhaka zinganciphisa ngempumelelo ukukhathala kwazo kokubona, ikakhulukazi labo abanamehlo omile. , intuthuko ingokoqobo ngempela.
2). Abantu abanesifo samehlo
Ukukhanya okuluhlaza okwesibhakabhaka okuyingozi kuyingozi kakhulu kubantu abane-fundus enesifo, ngakho-ke ukugqoka izibuko zokukhanya ezilwa nokuluhlaza okwesibhakabhaka kungavimba ngempumelelo ukukhanya okuluhlaza okwesibhakabhaka okuyingozi.
3). Abantu abenza umsebenzi okhethekile
Isibonelo, abasebenzi abasebenzisa ukushisela ngogesi kanye nengilazi yomlilo, ukukhanya okuluhlaza okwesibhakabhaka okuvezwe emsebenzini onjalo kudinga izibuko zokuzivikela zobungcweti ukuze kuvikelwe i-retina.
Akufanele izibuko ezikhanyayo eziluhlaza okwesibhakabhaka
1). Abantu abafuna ukuvimbela i-myopia
Ukuthi izibuko eziluhlaza okwesibhakabhaka zingavimbela i-myopia kuwukukhwabanisa ngokuphelele. Akukho mbiko emakethe ofakazela ukuthi izibuko eziluhlaza okwesibhakabhaka zingavimbela i-myopia, kodwa kunganciphisa ukukhathala kwamehlo. Isibonelo, lapho izingane zidlala ngemikhiqizo kagesi, zingagqoka izibuko eziluhlaza okwesibhakabhaka.
2). Abantu abadinga ukuqashelwa kombala
Isibonelo, abantu abasebenzisa ukwakheka komkhiqizo we-elekthronikhi abafaneleki ukugqoka izibuko zokukhanya eziluhlaza okwesibhakabhaka, ngoba ukuphambuka kwe-chromatic kuzothinta ukwahlulelwa kombala futhi kuzoba nomthelela othile emsebenzini.
4. Ungazikhetha Kanjani Izingilazi Ezikhanyayo Ezingaluphuzi?
Ngokuyinhloko bhekisela kuzinga lokuvimba ukukhanya okuluhlaza okwesibhakabhaka, ukudluliselwa kokukhanya okubonakalayo, umehluko wombala
Izinga Lokuvimba Ukukhanya Okuluhlaza okwesibhakabhaka
Izinga lokuvimba ukukhanya okuluhlaza okwesibhakabhaka linquma ikhono lokuvimba ukukhanya okuluhlaza okwesibhakabhaka, kodwa empeleni, izinga lokuvimba aliphezulu ngangokunokwenzeka. Ukugqoka ngaphansi kuka-30% akunangqondo kangako.
Ukuhanjiswa Kokukhanya Okubonakalayo
Okusho ukuthi, ukudlulisa, ikhono lokukhanya lokudlula kulensi. Uma ukudlulisa kukhulu, kulapho ukudlulisa kungcono khona futhi kulapho kucaca khona kakhulu.
Umehluko Wombala
Amalensi okukhanya alwa noluhlaza okwesibhakabhaka azophenduka abe phuzi futhi abangele ukuphambuka kwe-chromatic. Uma ungumklami nabanye abantu abanezidingo zokulungiswa kombala, akukhuthazwa ukugqoka izibuko zokukhanya eziluhlaza okwesibhakabhaka.
