Cishe wenza lokhu njengamanje - ubheka ikhompuyutha, ifoni noma ithebulethi ekhipha ukukhanya okuluhlaza okwesibhakabhaka.
Ukubuka noma yikuphi kwalokhu isikhathi eside kungaholela ku-Computer Vision Syndrome (CVS), uhlobo oluyingqayizivele lobunzima bamehlo olubangela izimpawu ezinjengamehlo omile, ububomvu, ikhanda elibuhlungu, nokungaboni kahle.
Isixazululo esisodwa esiphakanyiswe abakhiqizi bezingubo zamehlo izibuko ezivimba ukukhanya okuluhlaza okwesibhakabhaka. Kuthiwa zivimba ukukhanya okuluhlaza okungaba yingozi okukhishwa yi-electronics. Kodwa ukuthi ingabe lezi zibuko zinciphisa ngempela ukukhathala kwamehlo kuyimpikiswano.
Ukukhanya okuluhlaza kuwubude beza obuvela ngokwemvelo ekukhanyeni, kuhlanganise nokukhanya kwelanga. Ukukhanya okuluhlaza kunobude obufushane begagasi uma kuqhathaniswa nezinye izinhlobo zokukhanya. Lokhu kubalulekile ngoba odokotela baye bahlobanisa ukukhanya kwe-wavelength emifushane nengozi eyengeziwe yokulimala kwamehlo.
Nakuba izinto eziningi zikagesi, okuhlanganisa amalambu, zikhipha ukukhanya okuluhlaza okwesibhakabhaka, izikrini zekhompyutha nomabonakude ngokuvamile zikhipha ukukhanya okuluhlaza okwesibhakabhaka kakhulu kunezinye izinto zikagesi. Lokhu kungenxa yokuthi amakhompyutha namathelevishini ngokuvamile asebenzisa izibonisi zekristalu eliwuketshezi noma ama-LCD. Lezi zikrini zingabukeka zicwebile futhi zigqamile, kodwa futhi zikhipha ukukhanya okuluhlaza okwengeziwe kunezikrini ezingezona ze-LCD.
Kodwa-ke, i-Blu-ray ayiyona yonke into embi kangako. Ngenxa yokuthi le wavelength idalwe yilanga, ingakhuphula ukuqapha, ibonise ukuthi sekuyisikhathi sokuvuka futhi uqale usuku.
Ucwaningo oluningi ngokukhanya okuluhlaza nokulimala kwamehlo lwenziwe ezilwaneni noma ngaphansi kwezimo zaselabhorethri ezilawulwayo. Lokhu kwenza kube nzima ukukhomba kahle ukuthi ukukhanya okuluhlaza okwesibhakabhaka kubathinta kanjani abantu ezimeni zempilo zangempela.
Ngokusho kwe-American Academy of Ophthalmology, ukukhanya okuluhlaza okwesibhakabhaka okukhishwa ngamadivaysi kagesi akubangeli isifo samehlo. Bancamela ukusebenzisa ezinye izindlela ukuze bathuthukise ukulala kwabo, njengokugwema izikrini ngokuphelele ihora noma amabili ngaphambi kokulala.
Ukuze kuncishiswe umonakalo kanye nemiphumela engemihle engaba khona yokuchayeka isikhathi eside ekukhanyeni okuluhlaza okwesibhakabhaka, abakhiqizi bezingubo zamehlo benze amalensi engilazi yamehlo anezingubo ezikhethekile noma ama-tinti aklanyelwe ukukhombisa noma ukuvimba ukukhanya okuluhlaza okwesibhakabhaka ukuthi kungafiki emehlweni akho.
Umqondo wezibuko ezivimbela ukukhanya okuluhlaza okwesibhakabhaka ukuthi ukuzigqoka kunganciphisa ubunzima bamehlo, ukulimala kwamehlo kanye nokuphazamiseka kokulala. Kodwa alukho ucwaningo oluningi olusekela isimangalo sokuthi izibuko zingakwenza lokhu.
I-American Academy of Ophthalmology itusa ukugqoka izibuko esikhundleni samalensi okuxhumana uma uchitha isikhathi esiningi ubheka izinto zikagesi. Lokhu kungenxa yokuthi ukugqoka izibuko mancane amathuba okuba kubangele amehlo omile noma acasukile ngokusetshenziswa isikhathi eside kwamalensi okuxhumana.
Ngokwethiyori, izibuko ezikhanyayo eziluhlaza zingasiza ekunciphiseni ubunzima bamehlo. Kodwa lokhu akuzange kufakazelwe ngokuphelele ucwaningo.
Ukubuyekezwa kwango-2017 kubheke izivivinyo ezintathu ezihlukene ezihlanganisa izibuko ezivimba ukukhanya okuluhlaza okwesibhakabhaka kanye nokucindezeleka kwamehlo. Ababhali abatholanga ubufakazi obuthembekile bokuthi izibuko ezivimba ukukhanya okuluhlaza okwesibhakabhaka zihlotshaniswa nokubona okuthuthukisiwe, ukucindezelwa kwamehlo okuncane, noma izinga lokulala elithuthukisiwe.
Ucwaningo oluncane lwango-2017 lwalubandakanya abantu abangu-36 abagqoke izibuko ezikhanyayo okwesibhakabhaka noma ukuthatha i-placebo. Abacwaningi bathola ukuthi abantu ababegqoke izibuko ezikhanyayo eziluhlaza amahora amabili besebenza ngekhompyutha babhekana nokukhathala okuncane, ukulunywa, nobuhlungu bamehlo kunalabo ababengazigqoki izibuko ezikhanyayo eziluhlaza okwesibhakabhaka.
Ocwaningweni lwango-2021 lwabahlanganyeli abangu-120, ababambiqhaza bacelwa ukuthi bagqoke izibuko ezivimba ukukhanya okuluhlaza okwesibhakabhaka noma izibuko ezicacile futhi baqedele umsebenzi kukhompuyutha othathe amahora angu-2. Lapho ucwaningo seluphelile, abacwaningi abatholanga mehluko ekukhathaleni kwamehlo phakathi kwamaqembu amabili.
Izintengo zezibuko ezivimbe ukukhanya okuluhlaza okwesibhakabhaka ezitholakala ngaphandle kwekhawunta zisuka ku-$13 ziye ku-$60. Izibuko zokuvimbela ukukhanya okuhlaza okwesibhakabhaka zibiza kakhulu. Amanani azoncika ohlotsheni lohlaka olukhethayo futhi angasukela ku-$120 kuya ku-$200.
Uma unomshwalense wezempilo futhi udinga izibuko ezivimbe ukukhanya okuluhlaza okwesibhakabhaka, umshwalense wakho ungakhava ezinye zezindleko.
Nakuba izingilazi zokuvimbela ukukhanya okuluhlaza okwesibhakabhaka zitholakala ezitolo eziningi, azigunyazwa imiphakathi emikhulu yamehlo.
Kodwa uma ufuna ukuzama izibuko ezivimba ukukhanya okuluhlaza okwesibhakabhaka, gcina izinto ezimbalwa engqondweni:
Uma ungenaso isiqiniseko sokuthi izingilazi ezivimbela ukukhanya okuluhlaza okwesibhakabhaka zikulungele yini, noma uma zikulungele, ungaqala ngepheya lezibuko ezingabizi ezikhululekile ukuzigqoka.
Ukusebenza kwezibuko zokuvimbela ukukhanya okuluhlaza okwesibhakabhaka akuzange kuqinisekiswe izifundo eziningi. Kodwa-ke, uma uhleli kukhompuyutha noma ubuka i-TV isikhathi eside, usengakwazi ukuzizama ukuze ubone ukuthi ziyasiza yini ukunciphisa ubunzima bamehlo futhi zithuthukise izimpawu ezifana namehlo omile nokubabomvu.
Ungakwazi futhi ukunciphisa ukucindezeleka kwamehlo ngokuthatha ikhefu lehora lehora lemizuzu engu-10 kukhompuyutha yakho noma idivayisi yedijithali, usebenzisa amathonsi amehlo, nokugqoka izibuko esikhundleni samalensi okuxhumana.
Uma ukhathazekile ngokucindezeleka kwamehlo, khuluma nodokotela wakho noma udokotela wamehlo mayelana nezinye izindlela eziwusizo zokunciphisa noma yiziphi izimpawu zokucindezeleka kwamehlo okungenzeka ukuthi unazo.
