Kukhona ukukhanya okuluhlaza nxazonke. Lawa maza okukhanya anamandla aphezulu akhishwa elangeni, ageleze emkhathini womhlaba, futhi ahlangane nezinzwa zokukhanya esikhumbeni nasemehlweni. Abantu baya ngokuya bechayeka ekukhanyeni okuluhlaza okwesibhakabhaka ezindaweni zemvelo nezokwenziwa, ngoba amadivaysi e-LED afana namalaptop, omakhalekhukhwini namathebulethi nawo akhipha ukukhanya okuluhlaza okwesibhakabhaka.
Kuze kube manje, abukho ubufakazi obuningi bokuthi amazinga aphezulu okukhanya okuluhlaza okwesibhakabhaka azoletha noma yiziphi izingozi zesikhathi eside empilweni yabantu. Noma kunjalo, ucwaningo lusaqhubeka.
Lolu olunye ulwazi mayelana nobudlelwano phakathi kokukhanya okuluhlaza okwesibhakabhaka kanye nezimo zezempilo ezifana nokukhathala kwamehlo, ikhanda elibuhlungu kanye nemigraines.
I-Digital Eye Fatigue (DES) ichaza uchungechunge lwezimpawu ezihlobene nokusetshenziswa isikhathi eside kwamadivayisi edijithali. Izimpawu zihlanganisa:
Izikrini zekhompyutha, amakhompyutha aphathekayo, amaphilisi, nomakhalekhukhwini konke kungabangela ubunzima bamehlo edijithali. Ngayinye yalezi zisetshenziswa iphinde ikhiphe ukukhanya okuluhlaza okwesibhakabhaka. Lokhu kuxhumana kwenza abanye abacwaningi bazibuze ukuthi ingabe ukukhanya okuluhlaza okwesibhakabhaka kubangela ukukhathala kwamehlo edijithali.
Kuze kube manje, akukho ucwaningo oluningi olubonisa ukuthi umbala wokukhanya obangela izimpawu ze-DES. Abacwaningi bakholelwa ukuthi isisusa umsebenzi osondelene wesikhathi eside, hhayi umbala wokukhanya okhishwa isikrini.
I-Photophobia ukuzwela okwedlulele ekukhanyeni, okuthinta cishe ama-80% abaphethwe yi-migraine. I-photosensitivity ingaba namandla kangangokuthi abantu bangakhululeka kuphela ngokubuyela ekamelweni elimnyama.
Abacwaningi bathole ukuthi ukukhanya okuluhlaza okwesibhakabhaka, okumhlophe, okubomvu, ne-amber kungabhebhethekisa imigraines. Baphinde bakhulise ama-tics kanye nokuqina kwemisipha. Ocwaningweni lwe-2016 lweziguli ze-69 ezisebenzayo ze-migraine, ukukhanya okuluhlaza kuphela akuzange kukhulise ikhanda. Kwabanye abantu, ukukhanya okuluhlaza kungathuthukisa izimpawu zabo.
Kulolu cwaningo, ukukhanya okuluhlaza okwesibhakabhaka kwenza ama-neurons amaningi (amaseli athola ulwazi lwezinzwa futhi aluthumele ebuchosheni bakho) kuneminye imibala, okuholela abacwaningi ukuthi babize ukukhanya okuluhlaza okwesibhakabhaka ngokuthi uhlobo lokukhanya "oluningi kakhulu lwe-photophobic". Ukukhanya okuluhlaza okwesibhakabhaka, okubomvu, oku-amber nokumhlophe kukhanya, ikhanda liyaqina.
Kubalulekile ukuqaphela ukuthi nakuba ukukhanya okwesibhakabhaka kungenza i-migraine ibe yimbi kakhulu, akufani nokubangela i-migraines. Ucwaningo lwakamuva lubonise ukuthi akukhanyi ngokwayo okudala i-migraines. Kunalokho, le yindlela ubuchopho obusebenza ngayo ukukhanya. Abantu abathambekele ekubeni ne-migraine bangase babe nemizila yezinzwa kanye nama-photoreceptor azwela kakhulu ekukhanyeni.
Abacwaningi batusa ukuvimba wonke amaza okukhanya ngaphandle kokukhanya okuluhlaza phakathi nekhanda elinkenkethayo, futhi abanye abantu babika ukuthi lapho begqoke izibuko ezivimbela i-blue, ukuzwela kwabo ekukhanyeni kuyanyamalala.
Ucwaningo lwango-2018 lwaveza ukuthi ukuphazamiseka kokulala nekhanda elibuhlungu kuyahambisana. Izinkinga zokulala zingabangela ukungezwani kanye nemigraines, futhi ikhanda lingabangela ukuba ulahlekelwe ubuthongo.
I-Leptin iyi-hormone ekutshela ukuthi unamandla anele ngemva kokudla. Lapho amazinga e-leptin ehla, i-metabolism yakho ingase ishintshe ngandlela thile, ikwenze ube maningi amathuba okuba ukhuluphale. Ucwaningo lwango-2019 luthole ukuthi ngemuva kokuthi abantu besebenzise ama-iPads aluhlaza okwesibhakabhaka ebusuku, amazinga abo e-leptin ehla.
Ukuchayeka emisebeni ye-UVA ne-UVB (engabonakali) kungalimaza isikhumba futhi kwandise ingozi yomdlavuza wesikhumba. Kunobufakazi bokuthi ukuchayeka ekukhanyeni okuluhlaza kungalimaza isikhumba sakho. Ucwaningo lwango-2015 lwabonisa ukuthi ukuchayeka ekukhanyeni okuluhlaza okwesibhakabhaka kunciphisa ama-antioxidants futhi kwandisa inani lama-radicals mahhala esikhumbeni.
Ama-radicals wamahhala angalimaza i-DNA futhi aholele ekwakhekeni kwamangqamuzana omdlavuza. Ama-Antioxidants angavimbela ama-radicals mahhala ukuthi angakulimazi. Kubalulekile ukuqaphela ukuthi umthamo wokukhanya okwesibhakabhaka osetshenziswa abacwaningi ulingana nehora elilodwa lokushiswa ilanga emini eningizimu yeYurophu. Ucwaningo olwengeziwe luyadingeka ukuze uqonde ukuthi kungakanani ukukhanya okuluhlaza okwesibhakabhaka okukhishwa amadivayisi we-LED okuphephile esikhumbeni sakho.
Eminye imikhuba elula ingakusiza ukuthi uvimbele ukuphathwa yikhanda uma usebenzisa amadivaysi akhipha iblue. Nawa amanye amathiphu:
Uma uchitha isikhathi phambi kwekhompyutha isikhathi eside ngaphandle kokunaka isimo somzimba wakho, cishe uzophathwa yikhanda. INational Institutes of Health incoma ukuthi:
Uma ufaka umbhalo ngenkathi ubhekisela kudokhumenti, sekela iphepha elikwi-easeli. Uma iphepha seliseduze nezinga leso, lizonciphisa izikhathi lapho ikhanda nentamo yakho ikhuphuka ikhuphuka, futhi izokusindisa ekubeni ushintshe kakhulu ukugxila kwakho njalo lapho upheqa ikhasi.
Ukuqina kwemisipha kubangela amakhanda amaningi. Ukuze unciphise lokhu kucindezeleka, ungenza "ukulungiswa kwedeskithophu" ukuze ukhulule imisipha yekhanda, intamo, izingalo nomhlane ongaphezulu. Ungasetha isibali sikhathi efonini yakho ukuze uzikhumbuze ukuthi ume, uphumule futhi welule ngaphambi kokubuyela emsebenzini.
Uma idivayisi eyodwa ye-LED isetshenziswa amahora ambalwa ngesikhathi, leli su elilula lingasetshenziswa ukunciphisa ubungozi be-DES. Yima njalo ngemizuzu engu-20, gxila entweni eqhele ngamafidi angu-20, bese uyifundisisa cishe imizuzwana engama-20. Ushintsho lwebanga luvikela amehlo akho kude nokugxila okuqinile.
Amadivayisi amaningi akuvumela ukuthi ushintshe usuka ezibanini eziluhlaza uye kwimibala efudumele ebusuku. Kunobufakazi bokuthi ukushintshela kumodi yethoni efudumele noma ethi “Night Shift” kukhompyutha yethebhulethi kungasiza ekugcineni ikhono lomzimba lokukhiqiza i-melatonin, ihomoni eyenza umzimba ulale.
Uma ugqolozele isikrini noma ugxile emisebenzini enzima, ungase ucwayize kancane kunokuvamile. Uma ungacwayizi, ukusebenzisa amaconsi esweni, izinyembezi zokwenziwa, kanye nesiswakamisi sasehhovisi kungakusiza ugcine umswakama emehlweni akho.
Amehlo omile angabangela ukukhathala kwamehlo-abuye ahlotshaniswe nemigraines. Ucwaningo olukhulu lwango-2019 lwathola ukuthi abaphethwe yi-migraine banethuba eliphindwe ka-1.4 lokuthuthukisa iso elomile.
Sesha "izibuko ze-Blu-ray" ku-inthanethi, futhi uzobona inqwaba yezicaciso ezithi zivimbela ubunzima bamehlo edijithali nezinye izingozi. Nakuba ucwaningo luye lwabonisa ukuthi izibuko ezikhanyayo eziluhlaza okwesibhakabhaka zingavimbela ngokuphumelelayo ukukhanya okuluhlaza okwesibhakabhaka, abukho ubufakazi obuningi bokuthi lezi zibuko zingavimbela ukukhathala kwamehlo edijithali noma ubuhlungu bekhanda.
Abanye abantu babika ubuhlungu bekhanda ngenxa yokuvimbela izibuko ezikhanyayo eziluhlaza okwesibhakabhaka, kodwa alukho ucwaningo oluthembekile lokusekela noma ukuchaza le mibiko.
Ikhanda elibuhlungu livame ukuvela lapho izibuko ezintsha ziqala ukugqokwa noma lapho incwadi kadokotela ishintshwa. Uma unekhanda elibuhlungu ngenkathi ugqoke izibuko, linda izinsuku ezimbalwa ukuze ubone ukuthi amehlo akho aselungile yini futhi nekhanda lihambile. Uma kungenjalo, sicela ukhulume nodokotela wakho wamehlo noma ophthalmologist mayelana nezimpawu zakho.
Amahora amade okusebenza nokudlala kumadivayisi akhipha ukukhanya okuluhlaza okwesibhakabhaka njengomakhalekhukhwini, amakhompyutha aphathekayo, namathebulethi kungase kubangele ubuhlungu bekhanda, kodwa ukukhanya ngokwako kungase kungayibangeli inkinga. Kungaba ukuma, ukungezwani kwemisipha, ukuzwela ukukhanya noma ukukhathala kwamehlo.
Ukukhanya okuluhlaza okwesibhakabhaka kwenza ubuhlungu be-migraine, ukushaya kwenhliziyo kanye nokucindezeleka kube kubi nakakhulu. Ngakolunye uhlangothi, ukusebenzisa ukukhanya okuluhlaza kungakhulula i-migraines.
Ukuze uvimbele ubuhlungu bekhanda lapho usebenzisa izinto ezikhipha ukukhanya okuluhlaza okwesibhakabhaka, sicela ugcine amehlo akho emanzi, thatha ikhefu njalo ukuze welule umzimba wakho, sebenzisa indlela engu-20/20/20 ukuze uphumuze amehlo akho, futhi uqinisekise ukuthi umsebenzi wakho noma indawo yokuzijabulisa isethelwe ukukhuthaza. ukuma okunempilo.
Abacwaningi abakazi ukuthi ukukhanya okuluhlaza okwesibhakabhaka kuwathinta kanjani amehlo akho kanye nempilo yakho yonke, ngakho-ke uma ikhanda lithinta izinga lakho lempilo, kuwumqondo omuhle ukuhlola amehlo njalo futhi ukhulume nodokotela wakho.
Ngokuvimbela ukukhanya okuluhlaza okwesibhakabhaka ebusuku, kungenzeka ukuvimbela ukuphazamiseka komjikelezo wemvelo wokulala nokuvuka okubangelwa ukukhanya kokwenziwa kanye nemishini kagesi.
