Izingilazi ezisikiwe eziluhlaza okwesibhakabhaka, ngokwezinga elithile, zingaba "uqweqwe lwekhekhe ekhekheni" kodwa azifaneleki kubo bonke abantu. Ukukhetha okungaboni kahle kungase kubangele umonakalo. udokotela uyasikisela: "Abantu abanokukhubazeka kwe-retina noma labo abadinga ukusebenzisa izikrini ze-electronic kakhulu bangase bacabangele ukugqoka izibuko zokukhanya eziluhlaza okwesibhakabhaka. Nokho, abazali akufanele bakhetheizibuko ezikhanyayo eziluhlaza okwesibhakabhakaezinganeni ukuze nje kuvinjelwe i-myopia."
1.izibuko zokukhanya eziluhlaza okwesibhakabhaka azikwazi ukubambezela ukuqala kwe-myopia.
Abazali abaningi bayazibuza: Ingabe kufanele bakhethe izibuko zokukhanya eziluhlaza okwesibhakabhaka zezingane zabo ezibona eduze? Ukukhanya kwemvelo kuhlanganisa imibala eyisikhombisa ehlukene yokukhanya, futhi amandla akho akhula ngokulandelana. Ukukhanya okuluhlaza okwesibhakabhaka okubonakala emehlweni omuntu kubhekisela kububanzi be-wavelength obungu-400-500 nm. Yize konke kuwukukhanya okuluhlaza okwesibhakabhaka, ubude begagasi obuphakathi kuka-480-500 nm baziwa ngokuthi ukukhanya okuluhlaza okwesibhakabhaka kwe-long-wave, nokuthi phakathi kuka-400-480 nm kubizwa ngokuthi ukukhanya kwe-short-wave blue. Umgomo wezibuko ezikhanyayo eziluhlaza okwesibhakabhaka ukukhombisa ukukhanya okuluhlaza okwesibhakabhaka kwegagasi elifushane ngokumboza ungqimba endaweni engaphezulu yelensi noma ngokuhlanganisa izinto zokukhanya ezisikiwe okuluhlaza okwesibhakabhaka kwilensi ukuze umunce "ukukhanya okwesibhakabhaka," ukuzuza umphumela wokusika okuluhlaza okwesibhakabhaka.
Ukuhlola kubonisa ukuthi ukuhlunga ukukhanya okuluhlaza okwesibhakabhaka akukuqedi ukukhathala kwamehlo okubangelwa ukugqolozela izikrini zekhompyutha, futhi abukho ubufakazi obanele bokufakazela ukusebenza kahle kwakho ekuvimbeleni i-myopia ngokomtholampilo.
2.Ukulimala kokukhanya okuluhlaza okwesibhakabhaka okukhishwa ezikrinini ze-elekthronikhi kuya emehlweni kunqunyelwe.
Nakuba ukukhanya okuluhlaza kungekona okunamandla kakhulu ekukhanyeni okubonakalayo, kuwumthombo wokulimala ophathelene kakhulu. Lokhu kungenxa yokuthi, nakuba ukukhanya kwe-violet kunamandla anamandla, abantu baqapha kakhulu ngakho. Ngokuphambene, ukukhanya okuluhlaza okwesibhakabhaka kutholakala yonke indawo enkathini yedijithali futhi akunakugwenywa. I-LED ekukhanyeni nasezikrinini ze-elekthronikhi ikhipha ukukhanya okumhlophe kuma-chips aluhlaza okwesibhakabhaka avuselela i-phosphor ephuzi. Uma isikrini sikhanya, umbala ugqama kakhulu, ukukhanya okuluhlaza okwesibhakabhaka kuya phezulu.
Ukukhanya okuluhlaza kwegagasi elifushane okunamandla aphezulu kunamathuba aphezulu okuhlakazeka lapho kuhlangana nezinhlayiya ezincane ezisemoyeni, okubangela ukukhanya futhi kwenze izithombe zigxile phambi kwe-retina, okuholela ekuphambukeni kombono wombala. Ukuchayeka ekukhanyeni okweqile kwegagasi elifushane eliluhlaza okwesibhakabhaka ngaphambi kokulala kungase futhi kuvimbele ukukhiqizwa kwe-melatonin, okuholela ekuqwaleni. Ucwaningo lukhombisa ukuthi ukukhanya okuluhlaza okungu-400-450 nm kungalimaza i-macula ne-retina. Nokho, ukuxoxa ngomonakalo ngaphandle kokucabangela umthamo akulungile; ngakho, umthamo wokuchayeka wokukhanya okuluhlaza ubalulekile.
3.Akulungile ukugxeka konke ukukhanya okuluhlaza okwesibhakabhaka.
Ngisho nokukhanya kwe-short-wave blue kunezinzuzo zako; olunye ucwaningo lusikisela ukuthi ukukhanya okuluhlaza okwesibhakabhaka kwegagasi elifushane ekukhanyeni kwelanga kungase kubambe iqhaza ekuvimbeleni i-myopia ezinganeni, nakuba indlela ethile ingacacile. Ukukhanya okuluhlaza okwesibhakabhaka kwamagagasi amade kubalulekile ekulawuleni isigqi somzimba, kuthinte ukwakheka kwe-hypothalamus ye-melatonin ne-serotonin, kube nomthelela ekulawuleni ukulala, ukuthuthuka kwemizwa, nokuthuthukisa inkumbulo.
Ochwepheshe bayagcizelela: "Ilensi yethu ihlunga ngokwemvelo ukukhanya okuluhlaza okwesibhakabhaka, ngakho-ke kunokukhethaizibuko ezikhanyayo eziluhlaza okwesibhakabhaka, isihluthulelo sokuvikela amehlo ethu siwukusebenzisa ngendlela enengqondo. Lawula isikhathi nemvamisa yokusebenzisa imikhiqizo ye-elekthronikhi, gcina ibanga elifanele ngesikhathi sokusetshenziswa, futhi uqinisekise ukukhanya kwangaphakathi okumaphakathi. Kungcono ukuthi uhlolwe amehlo njalo ukuze uhlonze futhi welaphe izinkinga zamehlo kusenesikhathi."
izibuko ezikhanyayo eziluhlaza okwesibhakabhaka, ngokubonisa ukukhanya okuluhlaza okwesibhakabhaka okuyingozi ngefilimu emboziwe endaweni yelensi noma ngokuhlanganisa izici zokukhanya ezisikiwe okuhlaza okwesibhakabhaka endaweni yelensi, vimba ingxenye ebalulekile yokukhanya okuluhlaza okwesibhakabhaka, ngaleyo ndlela kunciphise ukulimala kwakho okuqhubekayo emehlweni.
Ngaphezu kwalokho, izibuko zokukhanya eziluhlaza okwesibhakabhaka zingathuthukisa ukuzwela kokugqama kwamehlo, zithuthukise ukusebenza kokubukwayo. Ucwaningo olwenziwa eShayina lubonise ukuthi ngemva kokuba abantu abadala begqoke amalensi okukhanya aluhlaza okwesibhakabhaka isikhashana, ukuzwela kwawo kokuqhathanisa emabangeni ahlukene nangaphansi kwezimo ezihlukahlukene zokukhanya nokucwebezela kwaba ngcono. Ezigulini ezithola i-retinal photocoagulation ngenxa ye-diabetesic retinopathy,izibuko ezikhanyayo eziluhlaza okwesibhakabhakaingathuthukisa ikhwalithi yokubuka yangemva kokusebenza. Kulabo abanenkinga yeso elomile, ikakhulukazi labo abasebenzisa amakhompuyutha noma amadivaysi eselula kakhulu, ukugqoka izibuko zokukhanya eziluhlaza okwesibhakabhaka kungathuthukisa ukuqonda okulungiswe kahle kakhulu kanye nokuzwela kokuqhathanisa kumazinga ahlukahlukene.
Kusukela kulo mbono, izibuko zokukhanya eziluhlaza okwesibhakabhaka ziyithuluzi eliwusizo lokuvikela amehlo.
Ekuphetheni,abakhiqizi be-lens opticalbaye basabela kahle ekukhuleni kwesidingo samalensi aluhlaza okwesibhakabhaka, okubonisa ukuzibophezela kwabo empilweni yamehlo kanye nokusungula izinto ezintsha zobuchwepheshe. Ngokuhlanganisa ubuchwepheshe obuthuthukisiwe bokuhlunga ukukhanya okuluhlaza okwesibhakabhaka emikhiqizweni yabo, laba bakhiqizi abagcini nje ngokubhekana nokukhathazeka kwabathengi mayelana nobunzima bamehlo edijithali kodwa futhi babeka izindinganiso ezintsha zezingubo zamehlo ezivikelayo. Lokhu kuthuthukiswa kugcizelela ukuzinikela kwemboni yezokubona ekuthuthukiseni ukunethezeka okubonakalayo kanye nokuvikela umbono emhlabeni wethu owandayo ogxile kudijithali.
