Ubuchwepheshe Besihlungi Sengilazi Esinokukhanya Okuluhlaza Okwesibhakabhaka Sokuvikela Amehlo
Endleleni yokuphila yedijithali yanamuhla, amehlo angenye yezitho zomzimba ezivame "ukusebenza ngokweqile." Ukubuka izikrini zamafoni aphathwayo, ama-laptop, amathebhulethi, namathelevishini sekuyinto evamile kubantu abaningi—kungakhathaliseki ukuthi kusemsebenzini, ekufundeni, noma ekuzijabuliseni. Naphezu kwalokhu kulula, izikhalazo ziyanda: amehlo akhathele, omile, anamanzi, ubunzima bokugxila, kanye nekhanda elibuhlungu. Esinye isici esixoxwa ngaso njalo ukuchayeka ekukhanyeni okuluhlaza okwesibhakabhaka okuvela kumadivayisi edijithali kanye nemithombo yokukhanya yesimanje njenge-LED. Lokhu kuholele ekuthuthukisweni kwezibuko ezinobuchwepheshe bokuhlunga ukukhanya okuluhlaza okwesibhakabhaka, ikhambi lokukhanya elenzelwe ukusiza ukunciphisa umthelela wokuchayeka ekukhanyeni okuluhlaza okwesibhakabhaka ekududuzeni kwamehlo nasempilweni.
Ukuqonda ukukhanya okuluhlaza okwesibhakabhaka nemiphumela yako
Ukukhanya okuluhlaza okwesibhakabhaka kuyingxenye ye-spectrum yokukhanya okubonakalayo enobude besikhathi obufushane kanye namandla aphezulu kuneminye imibala. Imithombo yokukhanya okuluhlaza okwesibhakabhaka ayihlanganisi nje kuphela izikrini zeselula kodwa nokukhanya kwelanga. Kodwa-ke, ubukhali besiqondiso kanye nobude bokuvezwa okuvela kuzikrini zedijithali kwenza ukukhanya okuluhlaza okwesibhakabhaka kube yinto ekhathazayo, ikakhulukazi uma kusetshenziswa amahora amaningi eduze.
Ukuchayeka ekukhanyeni okuluhlaza okwesibhakabhaka uma kusetshenziswa idivayisi yedijithali kuvame ukuhlotshaniswa ne-Digital Eye Strain (DSE). Izimpawu ziyahlukahluka, kusukela emehlweni abuhlungu, ukubona okufiphele okwesikhashana, umuzwa wokushisa, kuya ebuhlungwini obuzungeze amehlo. Kubalulekile ukuqonda ukuthi ukucindezeleka kwamehlo kwedijithali kunezinto eziningi: akukhona nje ukukhanya okuluhlaza okwesibhakabhaka, kodwa futhi nokukhanya kwesikrini, ukucwayiza okungajwayelekile, amabanga okubuka eduze, kanye nokuma kokusebenza okungenaphutha. Kodwa-ke, ukunciphisa izingxenye ezithile zokukhanya okuluhlaza okwesibhakabhaka kungasiza abanye abantu bazizwe bekhululekile kakhudlwana.
Ngaphezu kwalokho, ukukhanya okuluhlaza okwesibhakabhaka kuhlotshaniswa nesigqi se-circadian—uhlelo lwezinto eziphilayo olulawula umjikelezo wokulala nokuvuka. Ukuchayeka ekukhanyeni okuluhlaza okwesibhakabhaka ebusuku kungavimbela ukukhiqizwa kwe-melatonin, i-hormone esiza umzimba ukulungiselela ukulala. Ngenxa yalokho, umuntu angase abe nobunzima bokulala, ukulala kancane, noma ukushintsha ubuthongo kamuva.
Iyini ubuchwepheshe bokuhlunga ingilazi enokukhanya okuluhlaza okwesibhakabhaka?
Izibuko ezinobuchwepheshe bokuhlunga ukukhanya okuluhlaza okwesibhakabhaka zingamalensi ezibuko zamehlo aklanyelwe ukunciphisa ukudluliswa kokukhanya okuluhlaza okwesibhakabhaka, ikakhulukazi ebangeni elithile lamaza okukhanya elivame ukulawula ukukhishwa kwezikrini zedijithali nezibani ze-LED. Lobu buchwepheshe bungasetshenziswa ezinhlotsheni ezahlukene zamalensi—kufaka phakathi amalensi amancane, amalensi amaningi, amalensi e-astigmatism, amalensi aqhubekayo, kanye namalensi angagunyaziwe (amalensi e-plano) okusetshenziswa nsuku zonke phambi kwesikrini.
Ngokuvamile, izihlungi zokukhanya okuluhlaza okwesibhakabhaka azigcini nje "ngokuvimba konke ukukhanya okuluhlaza okwesibhakabhaka." Abakhiqizi abaningi baziklama ukuze zilondoloze umbono wombala wemvelo ngenkathi zinciphisa ukuchayeka kulezo ezibhekwa njengeziphazamisayo. Izindlela ziyahlukahluka, kodwa umgomo wokugcina uyafana: ukuthuthukisa induduzo yokubona nokunciphisa izikhalazo ezivela ekusetshenzisweni kwesikhathi eside kwamadivayisi edijithali.
Indlela ubuchwepheshe bokuhlunga ukukhanya okuluhlaza okwesibhakabhaka obusebenza ngayo
Ubuchwepheshe bokuhlunga ukukhanya okuluhlaza okwesibhakabhaka ezingilazini/kumalensi buvame ukusebenza ngezindlela ezimbili eziyinhloko:
1. Ukugqoka ebusweni belensi
Ezinye izembozo zingabonakalisa ukukhanya okuluhlaza okwesibhakabhaka okunamaza athile, okukuvimbela ukuthi kungafiki esweni. Ngezinye izikhathi lezi zembozo ziveza ukukhanya okuluhlaza okwesibhakabhaka noma okunsomi okubonakala ngaphandle, okufana nomphumela wokulwa nokukhanya kodwa okunesimo esihlukile se-spectral.
2. Izinto zelensi eziklanywe ngokukhethekile
Kweminye imikhiqizo, umphumela wokuhlunga awuveli nje kuphela embozweni kodwa futhi nasentweni yelensi uqobo, emunca ukukhanya okuluhlaza okwesibhakabhaka. Le ndlela ivame ukuzinza kakhulu ngoba umsebenzi "unamathele" ezintweni, yize usengahlanganiswa nezinye izinto zokuhlobisa.
Empeleni, amalensi okuhlunga ukukhanya okuluhlaza okwesibhakabhaka avame ukuhlanganiswa nezinye izici ezifana namalensi alwa nokukhanya (AR) ukuze kuncishiswe ukukhanya, amalensi alwa nokukhanya, kanye nokuvikelwa kwe-UV. Lokhu kuhlanganiswa kwenza amalensi abe mnandi ukuwagqoka ezimweni ezahlukahlukene zokukhanya.
Izinzuzo abasebenzisi abavame ukuzizwa
Okuhlangenwe nakho kwawo wonke umuntu kungahluka, kodwa ezinye zezinzuzo ezivame ukubikwa lapho usebenzisa izibuko zesihlungi sokukhanya okuluhlaza okwesibhakabhaka zifaka:
– Kunciphisa ukukhanya nokungakhululeki uma ubheka izikrini ezikhanyayo ngaphakathi endlini.
– Kusiza ekunciphiseni izimpawu zokukhathala kokubona, njengamehlo abuhlungu kanye nobunzima bokugxila ngemva kokusebenza isikhathi eside.
– Isekela induduzo yokulala uma ukusebenzisa amadivayisi edijithali ebusuku kungagwenywa, ngoba ukukhanya okuluhlaza okwesibhakabhaka kungancishiswa.
– Kuthuthukisa ikhwalithi yokubona uma kuhlanganiswa nesembozo esivimbela ukukhanya, njengoba ukukhanya okuvela ezibanini zegumbi noma ezikrinini kungancishiswa.
Kubalulekile ukuqaphela ukuthi amalensi okuhlunga ukukhanya okuluhlaza okwesibhakabhaka awayona "ikhambi" lazo zonke izinkinga zamehlo. Uma izimpawu zibangelwa ukubona eduze okungalungiswanga, amehlo omile njalo, noma amaphutha athile okukhanya, ukuhlolwa kwamehlo kuhlala kuyisinyathelo esiyinhloko.
Izithiyo ezingaba khona nezinto okufanele uziqaphele
Nakuba iwusizo kwabanye abasebenzisi, lobu buchwepheshe bunezinto eziningana okufanele bazicabangele:
– Ukushintsha kombala (ukushintsha kombala)
Amanye amalensi akhiqiza umbala ophuzi ofudumele kancane. Kwabachwepheshe bokudala abathembele ekunembeni kombala—abaklami bezithombe, abahleli bezithombe/amavidiyo—lokhu kungaphazamisa. Khetha umkhiqizo onezimangalo ezincane zokuphambuka kombala noma wenze umzamo wokuhlola.
- Ukuzindla esithombeni
Amalensi anezimbozo ezithile angabonisa ukukhanya okuluhlaza okwesibhakabhaka ezithombeni ezine-flash noma ukukhanya okuthile.
- Izimangalo ezahlukahlukene
Ukusebenza kahle kuncike kakhulu ekutheni ilensi ihlunga kangakanani amaza athile. Akuyona yonke imikhiqizo enemininingwane ecacile. Okungcono kakhulu, khetha amalensi kudokotela wamehlo odumile ongachaza izinga lokuhlunga kanye nokusetshenziswa okuhlosiwe.
Ngubani ofanele ukusetshenziswa?
Ubuchwepheshe bokuhlunga ingilazi obuluhlaza okwesibhakabhaka buvame ukufaneleka ku:
– Izisebenzi zasehhovisi ezibuka ama-monitor amahora angu-6-10 ngosuku.
– Abafundi noma abafundi abanemisebenzi yokufunda esekelwe esikrinini.
– Abasebenzisi bedivayisi abasebenza ebusuku.
– Abantu abazwela ukukhanya okuvela ezibanini ze-LED.
– Labo abavame ukuzwa izimpawu zamehlo omile futhi akhathele lapho besebenza ngedijithali (uma nje isimo sokungaguquguquki silungisiwe kahle).
Kodwa-ke, uma uhlangabezana nezimpawu ezinzima ezifana nobuhlungu bekhanda obuhlala bukhona, ukubona kabili, ukubona okufiphele isikhathi eside, noma amehlo abomvu angapheli, kufanele ubonane nodokotela wamehlo noma udokotela wamehlo. Izibuko zokuhlunga ukukhanya okuluhlaza okwesibhakabhaka zingaba yingxenye yesisombululo, kodwa azithathi indawo yokuxilongwa.
Amathiphu okukhulisa ukuvikelwa kwamehlo ngale kwezibuko
Ukuze kutholakale izinzuzo eziningi, izibuko zokuhlunga ukukhanya okuluhlaza okwesibhakabhaka kufanele zihlanganiswe nemikhuba yokubona enempilo:
1. Umthetho we-20-20-20: njalo ngemizuzu engama-20, bheka eceleni ngamafidi angu-20 (cishe amamitha ayi-6) imizuzwana engama-20.
2. Lungisa ukukhanya kwesikrini kanye nomehluko kube sezingeni elikhululekile, hhayi elikhanyayo kakhulu uma kuqhathaniswa nendawo ezungezile.
3. Naka ibanga: isikrini sekhompyutha kufanele sibe cishe ngamasentimitha angu-50-70 ukusuka emehlweni.
4. Khanyisa amehlo njalo noma sebenzisa amaconsi amehlo uma kunconywa uchwepheshe wezempilo, ngoba ukubuka isikrini kubangela ukuthi imvamisa yokucwayiza inciphe.
5. Sebenzisa imodi yasebusuku kudivayisi ntambama nakusihlwa.
6. Sebenzisa ukukhanya kwegumbi okufanele, gwema ukukhanyisa okuqondile esikrinini.
Isiphetho
Izibuko ezinobuchwepheshe bokuhlunga ukukhanya okuluhlaza okwesibhakabhaka zavela njengempendulo yezidingo zesikhathi sedijithali, lapho amehlo evezwa khona ezikrinini isikhathi eside nsuku zonke. Ngokuhlunga noma ukubonakalisa ingxenye ye-spectrum yokukhanya okuluhlaza okwesibhakabhaka, la malensi angasiza ekuthuthukiseni induduzo yokubona, ukunciphisa ukukhanya, futhi angase asekele ikhwalithi yokulala—ikakhulukazi kubasebenzisi ababuka izikrini ngenkuthalo ebusuku. Kodwa-ke, imiphumela iyahlukahluka futhi ayithathi indawo yokuhlolwa kwamehlo noma imikhuba emihle ye-ergonomic. Ukuhlanganisa izibuko zokuhlunga ukukhanya okuluhlaza okwesibhakabhaka nezilungiselelo zesikrini ezinempilo namaphethini okusebenza kuyindlela engcono kakhulu yokugcina induduzo yamehlo kanye nokukhiqiza isikhathi eside.
Uma ungathanda, ngingavumelanisa lesi sihloko nezidingo zakho ezithile—isibonelo, isitayela esisemthethweni, inguqulo yebhulogi ye-optics, noma ezinye izingxenye ezincane njengezincomo zokukhetha amalensi ngokusekelwe emsebenzini kanye nesabelomali.
