Ngiqinisekile ukuthi uzwile ngezingilazi ezivimbayo eziluhlaza, akunjalo?
Abantu abaningi badinga ukusebenza ngomakhalekhukhwini namakhompyutha isikhathi eside, efakwe ngokukhethekile izibuko ezikhanyayo ezilwa nohlaza okwesibhakabhaka;Abazali abaningi bezwa ukuthi lolu hlobo lwezibuko lungavimbela i-myopia, lulungiselele izingane zabo i-pair.Kancane kancane, izibuko ezivimbelayo eziluhlaza okwesibhakabhaka - ezikhanyayo zaba "ukuvikelwa kwamehlo.
Kodwa ingabe kuyamangalisa ngempela?Kuyini ukukhanya okuluhlaza okwesibhakabhaka?Kungani kuqashwe kuso?Ingabe ukuvimbela izibuko ezikhanyayo eziluhlaza okwesibhakabhaka ukuvimbela myopia ngempela?Manje bhekisisa.
Kuyini ukukhanya okuluhlaza okwesibhakabhaka?Uyini umphumela emehlweni?
Sivame ukusho ukuthi ukukhanya kwemvelo, okwaziwa nangokuthi ukukhanya kwelanga, sakhiwe obomvu, osawolintshi, ophuzi, oluhlaza okotshani, oluhlaza okwesibhakabhaka, we-indigo, onsomi 7 imibala ehlukene yokukhanya, phakathi kwawo "okuluhlaza okwesibhakabhaka" owaziwa nangokuthi ukukhanya okuluhlaza okwesibhakabhaka, ububanzi bayo be-wavelength phakathi kuka-380nm - 500nm.
Ukukhanya okuluhlaza okwesibhakabhaka kuthinta amehlo ngazo zombili izindlela:
Ukukhanya okuluhlaza okwesibhakabhaka kwe-long-wave ebangeni le-wavelength phakathi kuka-440nm no-500nm kuyathandeka
Idabula ku-retina iye emthanjeni wamehlo, lapho idluliselwa ku-hypothalamus ukuze ihlanganise i-melatonin ne-serotonin, engakusiza ulale, uthuthukise isimo sakho sengqondo, futhi uthuthukise inkumbulo yakho.
Ukukhanya okuluhlaza okwesibhakabhaka kwegagasi elifushane ebangeni lamaza angama-380nm kuya ku-440nm kuyingozi
Inganciphisa izinga lokulala futhi ibangele ngisho nokulimala okuncane ku-retina.
Ngaphezu kokukhanya kwelanga, ukukhanya okuvela ekukhanyeni, okuvela ezikrinini ze-elekthronikhi, yonke le mithombo inokusabalalisa ukukhanya okuluhlaza okwesibhakabhaka.Njengamanje, zonke izibani ezijwayelekile zezimboni nezibani ezifanelekayo, amandla okukhanya okuluhlaza okwesibhakabhaka angaphakathi kwebanga eliphephile, ngakho-ke ukukhanya okuluhlaza okwesibhakabhaka okukhishwe ukusetshenziswa kwansuku zonke kwezibani nezibani, umthelela emehlweni abantu abavamile awunalutho.
Ingxenye yokukhanya okuluhlaza okwesibhakabhaka kwamagagasi amafushane ekukhanyeni kwesikrini iphakeme kunaleyo yelanga, kodwa ingqikithi yamandla incane kakhulu kunaleyo yelanga.Imikhiqizo ye-elekthronikhi efanelekele ukulethwa nayo ayanele ukuthi idale umonakalo ku-retina.
Njengamanje, ukuhlolwa okufanelekile kungaqinisekisa: umthamo omkhulu, ukukhanya okuluhlaza okwesibhakabhaka isikhathi eside okuqhubekayo, kungaholela ku-retinal photoreceptor apoptosis.Kodwa ngenxa yamandla aphansi okukhanya okuluhlaza okwesibhakabhaka, asakazwa ukukhanya kwesikrini, nangenxa yokuthi abantu abaningi basebenzisa izikrini ze-electronic isikhathi esilinganiselwe, azikho izimo zokukhanya okuluhlaza okulimaza ngokuqondile i-retina yeso lomuntu.
Uyini umgomo wezibuko ezikhanyayo eziphikisana nohlaza okwesibhakabhaka?
Izingilazi ezivimba okuluhlaza okwesibhakabhaka zibonakala ngeso lenyama njengokungathi zimbozwe ifilimu ephuzi ebonisa ukukhanya okuluhlaza okwesibhakabhaka okuyigagasi elifushane ngendwangu engaphezulu kwelensi.Noma engeza isici sokuvimbela okuluhlaza okwesibhakabhaka ku-lens substrate, ukuze ubambe ukukhanya okuluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka.
Ngokwendinganiso ethi "Izimfuneko Zobuchwepheshe Zokusebenza Kwempilo Ekhanyayo Nokuphepha Okukhanyayo kwe-Blue Light Protective Film", isilinganiso sokudlulisa ukukhanya sokukhanya okuluhlaza okwesibhakabhaka kwamagagasi amade kufanele sibe sikhulu kuno-80%, okusho ukuthi ukukhanya okuluhlaza okwesibhakabhaka okuzuzisayo kokukhanya okuluhlaza kwegagasi elide akudingeki ukuthi kuvikelwe.Okudingwa yizibuko ezivimbelayo eziluhlaza okwesibhakabhaka ukuze zibonise futhi zimunce ukukhanya okuluhlaza okulimazayo, okwaziwa ngokuthi ukukhanya okuluhlaza okwesibhakabhaka okufushane.
Kodwa-ke, ikhwalithi yezibuko ezikhanyayo ezihlaza okwesibhakabhaka emakethe ayilingani, ezinye izibuko ezikhanyayo ze-anti-blue ezingafanelekile, nakuba zingafinyelela umphumela wokukhanya okuhlaza okwesibhakabhaka okulwa ne-short-wave, kodwa futhi zivimbele ukukhanya kwe-long-wave blue;Ngakho-ke, lapho sikhetha izibuko ezikhanyayo eziphikisana nohlaza okwesibhakabhaka, kufanele sinake isilinganiso sokudlulisela sokukhanya okuluhlaza okwesibhakabhaka kwamagagasi amade.
Ingabe ingakwazi ukuvimbela izibuko ezikhanyayo eziluhlaza okwesibhakabhaka ukugwema ukujula kwe-myopic?
Abukho ubufakazi obuqondile bokuthi izibuko ezivimbela i-blue zivimbela i-myopia.
Sivame ukusho ukuthi isikhathi eside sokubuka ikhompyutha, i-TV, umakhalekhukhwini, kuzodala ukulahlekelwa umbono, ngoba isikhathi eside ukubuka izinto eziseduze kuzoshintsha uhlelo lwe-refractive noma i-eksisi yeso, ngaleyo ndlela kuthinte umbono.
Ngakho-ke, kulabo abafuna ukugqoka izibuko zokuvimbela ukukhanya okuluhlaza okwesibhakabhaka ukuze banciphise isivinini se-myopia, asikho isidingo sokugqoka.
Nakuba ukukhanya okuluhlaza okwesibhakabhaka kungahlotshaniswa ne-myopia, kunomthelela omkhulu ezigulini zamehlo omile.Ngo-2016, uchwepheshe wamehlo omile waseJapan uMinako Kaido wafakazela ukuthi ukunciphisa ukuvezwa kokukhanya okuluhlaza okwesibhakabhaka kwe-short-wave emehlweni kungathuthukisa ngempumelelo izimpawu zamehlo omile ezigulini ezineso elomile.Ngakho-ke abantu abachitha isikhathi esiningi bephambi kwesikrini bangase bazizwe bekhululekile ukugqoka izibuko ezivimbela i-blue.
Laba bantu batusa ukuyigqoka
(1) Ifanele izisebenzi zesikrini ezinezimpawu zamehlo omile: ngenxa yokuthi ukuvimbela ukukhanya okuluhlaza okwesibhakabhaka kwegagasi elifushane kungathuthukisa ukuzinza kwefilimu yezinyembezi yeziguli zamehlo omile, ngakho izibuko ezivikela uhlaza okwesibhakabhaka zinganciphisa ukukhathala okubonakalayo kwabasebenzi besikrini.
(2) Ifanele abantu abane-macular degeneration: ukukhanya okuluhlaza okwesibhakabhaka kwe-short-wave kubantu abane-fundus isifo sokungena kuzoba namandla kunabantu abavamile, ukugqoka izibuko ezikhanyayo eziluhlaza okwesibhakabhaka kungase kube nomthelela othile.
③ Ifanele abantu abenza umsebenzi okhethekile, njengabasebenzi abashisa ingilazi futhi basebenzise ukushisela kukagesi: lolu hlobo lwabantu lungase luvezwe imithamo emikhulu yokukhanya okuluhlaza okwesibhakabhaka, ngakho-ke kudingeka izingilazi zokuzivikela ezichwepheshile ukuze kuvikelwe i-retina.
Ayibafanele abantu abanjalo
① Azizifanele izingane ezincane ezifuna ukuvimbela nokulawula i-myopia: awukho umbiko ofakazela ukuthi ukugqoka izibuko ezikhanyayo eziluhlaza okwesibhakabhaka kungabambezela ukukhula kwe-myopia, futhi umbala ongemuva wezibuko ezikhanyayo eziphikisana nokuluhlaza okwesibhakabhaka unombala ophuzi, ongathinta ukukhula kokubuka kwezingane.
② Ayifanele abantu abanezidingo zokuhlonza umbala: izibuko ezikhanyayo eziluhlaza okwesibhakabhaka zizovimba ukukhanya okuluhlaza okwesibhakabhaka, ziveze umbala ohambisanayo wophuzi oluhlaza okwesibhakabhaka, futhi umbala wesikrini uzohlanekezelwa, ngakho-ke kungase kube nomthelela othile emsebenzini walolu hlobo lwabantu.
