Izibuko eziluhlaza okwesibhakabhaka ezivimba ukukhanya ziye zathandwa kakhulu eminyakeni yamuva, nabantu abaningi ebabona njengesixazululo esingahle banciphise ubunzima beso futhi bathuthukise ikhwalithi yokulala. Ukusebenza kwalezi zibuko zisihloko kuyisihloko sentshisekelo futhi kufundze izifundo ezahlukahlukene kanye nezimpikiswano. Kulesi sihloko, sizohlola izinzuzo ezingaba khona zokukhanya okuluhlaza okwesibhakabhaka okuvimba izibuko, isayensi ngemuva kwazo, futhi ezinye izinto okufanele zizikhumbule lapho zisebenzisa. Ukukhanya okuluhlaza okwesibhakabhaka kungukukhanya okunamandla, ukukhanya okufushane kwe-wavelength kukhishwe izikrini zedijithali, ukukhanyisa kwaled, nelanga. Ukuchayeka ngokukhanya okuluhlaza okwesibhakabhaka kusuka ezikrinini, ikakhulukazi ebusuku, kuphazamisa umjikelezo wemvelo wokulala emzimbeni ngokucindezela ukukhiqizwa kwe-melatonin, i-hormone elawula ukulala. Ngokwengeziwe, ukuvezwa isikhathi eside kokukhanya okuluhlaza okwesibhakabhaka kuhlotshaniswa nohlobo lwe-Digital Eye, isimo esibonakala ngokungaphatheki kwamehlo, ukoma nokukhathala. Izibuko eziluhlaza okwesibhakabhaka zenzelwe ukuhlunga noma zivimbele ukukhanya okuluhlaza okwesibhakabhaka, ngaleyo ndlela kunciphise inani lokukhanya okuluhlaza okwesibhakabhaka okufika emehlweni akho. Amanye ama-lens ahlelwe ngokukhethekile ukuqondisa ama-wavelength amabi kakhulu wokukhanya okuluhlaza okwesibhakabhaka, kanti amanye angaba nomphumela wokuhlunga okujwayelekile. Umqondo ngemuva kwalezi zingilazi ukunciphisa imiphumela emibi engaba khona yokukhanya okuluhlaza okwesibhakabhaka ngempilo yamehlo nasemaphethini okulala. Ucwaningo oluningi luphenye imiphumela yokukhanya okuluhlaza okwesibhakabhaka okuvimba izibuko ngokukhathala kwamehlo kanye nekhwalithi yokulala.
Ucwaningo lwe-2017 olushicilelwe ephephabhukwini lwezeMpilo Yentsha ngathola ukuthi ababambiqhaza abagqoke izingilazi ezivinjelwe ukukhanya okuluhlaza okwesibhakabhaka ngenkathi besebenzisa amadivaysi edijithali abahlangabezana nezimpawu ezincishisiwe kakhulu zohlobo lwamehlo uma benza abahlanganyeli abangazange bagqoke izibuko. Olunye ucwaningo olushicilelwe ngo-2017 ephephabhukwini lwezempilo yokulala lubonise ukuthi ukugqoka izingilazi eziluhlaza okwesibhakabhaka ebusuku kungathuthukisa ikhwalithi yokulala ngokukhulisa amazinga e-melatonin futhi kuncishiswe isikhathi esithatha isikhathi sokulala. Ngakolunye uhlangothi, ezinye izifundo ziye zangabaza ekusebenzeni kahle kokukhanya okuluhlaza okwesibhakabhaka. Ucwaningo luka-2018 olushicilelwe ephephabhukwini lwe-Ophthalmology kanye ne-physioliological Optics luphetha ngokuthi ngenkathi ukuvezwa kokukhanya okuluhlaza kungadala ukungaphatheki kahle, ubufakazi bokuthi ama-lens akhanyayo akhanyayo angancipha. Ngokufanayo, ukubuyekezwa okungu-2020 okushicilelwe ku-Cochrane Database yokubuyekezwa okuhleliwe kuthola ubufakazi obanele bokusekela ukusetshenziswa kwezibuko eziluhlaza okwesibhakabhaka ukunciphisa uhlobo lwedijithali. Yize imiphumela yocwaningo ixubene, abantu abaningi babika ukuthuthuka okuzenzakalelayo enduduzweni yamehlo nasempilweni yokulala ngemuva kokugqoka izingilazi eziluhlaza okwesibhakabhaka ezimpilweni zabo zansuku zonke. Kubalulekile ukuqaphela ukuthi ukusabela komuntu kulezi zingilazi kungahluka ngokuya ngezinto ezifana nesikhathi sokuvezwa kwesikrini, ukuthambekela komuntu ngamunye kokuxinana kwamehlo, namaphethini okulala akhona. Lapho ucubungula ukusebenza okungaba khona kokukhanya okuluhlaza okwesibhakabhaka okuvimba izibuko, kubalulekile ukuqonda ukuthi lezi zingilazi akuzona isixazululo esisodwa-sonke isixazululo. Izici ezifana nekhwalithi yama-lens, ama-wavelength athile akhanyayo ahlosiwe, futhi umehluko ngamunye ku-physiology wamehlo kanye nokuzwela okukhanyayo konke kuthinta imiphumela ebonakalayo yokugqoka lezi zibuko. Ngaphezu kwalokho, ukuthatha indlela ephelele yempilo yamehlo nokuhlanzeka kokulala kubalulekile. Ngaphezu kokusebenzisa izingilazi eziluhlaza okwesibhakabhaka ezivimba izibuko, ukuthatha amakhefu esikrinini ejwayelekile, ukuguqula ukugqama kwesikrini kanye nezilungiselelo zokungafani, futhi uzilolonga imikhuba emihle yokulala, nokuzijwayeza kahle izici zokulala ziyinto ebalulekile yokugcina impilo yamehlo ephelele futhi ithuthukise ukulala okuphumuzayo.
Sekukonke, ngenkathi ubufakazi besayensi ekusebenzeni kwezibuko eziluhlaza okwesibhakabhaka bungafani, kukhona ukwesekwa okukhulayo kwamandla abo okunciphisa ubunzima bamehlo nokwenza ngcono ukulala kwabanye abantu. Uma uhlangabezana nokungaphatheki kahle esikrinini esikhathi eside noma unenkinga yokulala ngemuva kokusebenzisa amadivaysi edijithali, kungakufanele kucatshangelwe ukubheka izingilazi ezivimba ukukhanya eziluhlaza okwesibhakabhaka. Kodwa-ke, ukusetshenziswa kwazo kumele kubhekwe njengengxenye yokunakekelwa kwamehlo okuphelele nohlelo lokuhlanzeka lokulala, futhi ukhumbule ukuthi izimpendulo ngazinye zingahluka. Ukubonisana nochwepheshe wokunakekelwa kwamehlo kunganikeza umhlahlandlela owenziwe umuntu wokuthi ungafaka kanjani ukukhanya okuluhlaza okuvimba izingilazi empilweni yakho yansuku zonke.
