Izingilazi zokukhanya eziluhlaza okwesibhakabhaka zingaba, ngezinga elithile, "i-icing on the cake" kodwa azifaneleki kuzo zonke izinhlobo zabantu. Ukukhetha okungaboni kahle kungase kube nemiphumela emibi. Udokotela uphakamisa ukuthi: "Abantu abanezinkinga ze-retina noma labo abadinga ukusebenzisa izikrini zikagesi kakhulu bangacabanga ukugqoka izingilazi zokukhanya eziluhlaza okwesibhakabhaka. Kodwa-ke, abazali akufanele bakhetheizibuko zokukhanya eziluhlaza okwesibhakabhakaizingane ukuze nje zivimbele i-myopia.
1.Izibuko ezikhanyayo eziluhlaza okwesibhakabhaka azikwazi ukulibazisa ukuqala kwe-myopia.
Abazali abaningi bayazibuza: Ingabe kufanele bakhethe izibuko zokukhanya eziluhlaza okwesibhakabhaka zezingane zabo ezibona eduze? Ukukhanya kwemvelo kuqukethe imibala eyisikhombisa ehlukene yokukhanya, amandla azo enyuka ngokulandelana. Ukukhanya okuluhlaza okwesibhakabhaka okubonakala emehlweni abantu kubhekisela ebangeni lobude bamaza obungu-400-500 nm. Nakuba konke kungukukhanya okuluhlaza okwesibhakabhaka, ubude bamaza obuphakathi kuka-480-500 nm baziwa ngokuthi ukukhanya okuluhlaza okwesibhakabhaka okunamaza amade, futhi lokho okuphakathi kuka-400-480 nm kubizwa ngokuthi ukukhanya okuluhlaza okwesibhakabhaka okunamaza amafushane. Umgomo wezibuko zokukhanya eziluhlaza okwesibhakabhaka ukubonakalisa ukukhanya okuluhlaza okwesibhakabhaka okunamaza amafushane ngokumboza ungqimba ebusweni belensi noma ngokufaka izinto zokukhanya okuluhlaza okwesibhakabhaka kulensi ukuze kuthathwe "ukukhanya okuluhlaza okwesibhakabhaka," kufezwe umphumela wokusika okuluhlaza okwesibhakabhaka.
Ukuhlolwa kubonisa ukuthi ukuhlunga ukukhanya okuluhlaza okwesibhakabhaka akunciphisi ukukhathala kwamehlo okubangelwa ukubuka izikrini zekhompyutha, futhi abukho ubufakazi obanele bokufakazela ukusebenza kwayo ekuvimbeleni i-myopia ngokwezokwelapha.
2. Umonakalo wokukhanya okuluhlaza okwesibhakabhaka okukhishwa yizikrini ze-elekthronikhi emehlweni ulinganiselwe.
Nakuba ukukhanya okuluhlaza okwesibhakabhaka kungesona esinamandla kakhulu ekukhanyeni okubonakalayo, kungumthombo wengozi okhathazayo kakhulu. Lokhu kungenxa yokuthi, nakuba ukukhanya okuluhlaza okwesibhakabhaka kunamandla aqinile, abantu baqaphe kakhulu ngakho. Ngokuphambene nalokho, ukukhanya okuluhlaza okwesibhakabhaka kutholakala yonke indawo esikhathini sedijithali futhi akunakugwenywa. I-LED ekukhanyeni nasezikrinini ze-elekthronikhi ikhipha ukukhanya okumhlophe ngama-chip okukhanya okuluhlaza okwesibhakabhaka avuselela i-phosphor ephuzi. Uma isikrini sikhanya kakhulu, umbala ukhanya kakhulu, kulapho ukukhanya okuluhlaza okwesibhakabhaka kukhuphuka khona.
Ukukhanya okuluhlaza okwesibhakabhaka okunamagagasi amafushane okunamandla aphezulu kunethuba eliphezulu lokusabalala lapho kuhlangatshezwana nezinhlayiya ezincane emoyeni, okubangela ukukhanya okukhulu futhi kwenze izithombe zigxile phambi kwe-retina, okuholela ekuphambukeni kokubona umbala. Ukuchayeka ekukhanyeni okuluhlaza okwesibhakabhaka okunamagagasi amafushane ngokweqile ngaphambi kokulala kungavimbela nokukhiqizwa kwe-melatonin, okuholela ekuqwasheni. Izifundo zibonisa ukuthi ukukhanya okuluhlaza okwesibhakabhaka okungu-400-450 nm kungalimaza i-macula ne-retina. Kodwa-ke, ukuxoxa ngomonakalo ngaphandle kokucabangela umthamo akufanele; ngakho-ke, isilinganiso sokuvezwa kokukhanya okuluhlaza okwesibhakabhaka sibalulekile.
3. Akulungile ukulahla konke ukukhanya okuluhlaza okwesibhakabhaka.
Ngisho nokukhanya okuluhlaza okwesibhakabhaka okunamagagasi amafushane kunezinzuzo zako; olunye ucwaningo lusikisela ukuthi ukukhanya okuluhlaza okwesibhakabhaka okunamagagasi amafushane ekukhanyeni kwelanga kwangaphandle kungadlala indima ekuvimbeleni i-myopia ezinganeni, yize indlela ethile ingacacile. Ukukhanya okuluhlaza okwesibhakabhaka okunamagagasi amade kubalulekile ekulawuleni isigqi somzimba, kuthinta ukwakheka kwe-melatonin ne-serotonin kwi-hypothalamus, kuthonye ukulawulwa kokulala, ukuthuthukiswa kwemizwa, kanye nokuthuthukiswa kwenkumbulo.
Ochwepheshe bagcizelela ukuthi: "Ilensi yethu ihlunga ngokwemvelo ukukhanya okuluhlaza okwesibhakabhaka, ngakho-ke kunokukhethaizibuko zokukhanya eziluhlaza okwesibhakabhaka, isihluthulelo sokuvikela amehlo ethu ukusetshenziswa okufanele. Lawula isikhathi kanye nemvamisa yokusebenzisa imikhiqizo kagesi, gcina ibanga elifanele ngesikhathi sokusetshenziswa, futhi uqinisekise ukukhanya okuphakathi endlini. Kungcono ukuhlolwa kwamehlo njalo ukuze kutholakale futhi kwelashwe izinkinga zamehlo ngesikhathi.
izibuko zokukhanya eziluhlaza okwesibhakabhaka, ngokubonakalisa ukukhanya okuluhlaza okwesibhakabhaka okuyingozi ngefilimu embozwe ebusweni belensi noma ukufaka izinto zokukhanya eziluhlaza okwesibhakabhaka ezintweni zelensi, kuvimbela ingxenye enkulu yokukhanya okuluhlaza okwesibhakabhaka, ngaleyo ndlela kunciphisa umonakalo oqhubekayo emehlweni.
Ngaphezu kwalokho, izibuko zokukhanya eziluhlaza okwesibhakabhaka zingathuthukisa ukuzwela kwamehlo okuphambene, zithuthukise ukusebenza kokubona. Ucwaningo eShayina lubonise ukuthi ngemva kokuba abantu abadala begqoke amalensi okukhanya aluhlaza okwesibhakabhaka isikhashana, ukuzwela kwabo okuphambene kumabanga ahlukene nangaphansi kwezimo ezahlukene zokukhanya nokugqama kuthuthukile. Ezigulini ezithola i-retina photocoagulation ngenxa ye-retinopathy yesifo sikashukela,izibuko zokukhanya eziluhlaza okwesibhakabhakakungathuthukisa ikhwalithi yokubona ngemva kokuhlinzwa. Kulabo abanesifo samehlo esomile, ikakhulukazi labo abasebenzisa amakhompyutha noma amadivayisi eselula kakhulu, ukugqoka izibuko zokukhanya eziluhlaza okwesibhakabhaka kungathuthukisa ukuqonda okubonakalayo okulungisiwe kahle kanye nokuzwela ukuqhathanisa ngamazinga ahlukahlukene.
Kusukela kulo mbono, izibuko ezikhanyayo eziluhlaza okwesibhakabhaka ziyithuluzi eliwusizo lokuvikela amehlo.
Ekuphetheni,abakhiqizi belensi yokukhanyabaphendule ngobuhlakani ekukhuleni kwesidingo samalensi aluhlaza okwesibhakabhaka, okubonisa ukuzibophezela kwabo empilweni yamehlo kanye nokusungula izinto ezintsha kwezobuchwepheshe. Ngokufaka ubuchwepheshe obuthuthukisiwe bokuhlunga ukukhanya okuluhlaza okwesibhakabhaka emikhiqizweni yabo, laba bakhiqizi abagcini nje ngokubhekana nokukhathazeka kwabathengi mayelana nokucindezeleka kwamehlo kwedijithali kodwa futhi babeka amazinga amasha ezindongeni zamehlo ezivikelayo. Lokhu kuthuthukiswa kugcizelela ukuzinikela kwemboni ye-optical ekuthuthukiseni induduzo yokubona kanye nombono wokuvikela ezweni lethu eligxile kakhulu kudijithali.
