Ndigqibele nini ukukhangela ixesha lokungena kwescreen sefowuni yakho? Ngoku, ubungakanani bexesha olichitha ujonge, yithi, ikhompyuter yomsebenzi, iTV (hi, iNetflix binge), okanye i-e-reader ukongeza kwiscreen sefowuni yakho. Uyoyikeka, huh?

Njengokuba ubomi buye buxhomekeka kakhulu kwizikrini, kunjalo ke kwintengiso yeemveliso ezijolise ekunciphiseni ifuthe lalo lonke eli xesha lescreen kulusu lwakho, imizimba, kunye neengqondo. Enye yezona zibalaseleyo? Iiglasi eziluhlaza okwesibhakabhaka-impahla yamehlo (eneelensi okanye ezingenazo zokulungisa) ezithi zikhusela amehlo akho kwimitha yokukhanya eyingozi ephuma kuzo zonke izixhobo zakho ozithandayo.

Ngokuqinisekileyo, iiglasi zokukhanya eziluhlaza okwesibhakabhaka sisizathu esikhulu kuye nabani na onqwenela iiglasi ukujonga-kodwa unombono we-20/20-ukulungelelanisa ukuthenga nokugqoka iperi. Kodwa ngaba iiglasi zokukhanya eziluhlaza ziyasebenza, okanye ngaba yonke i-hype? Kwaye, ngalo nto, ngaba ukukhanya okuluhlaza okwesibhakabhaka konke okuyingozi emehlweni akho? Apha, iingcali ziphendula yonke i-Q yakho.

Yintoni ukukhanya okuluhlaza okwesibhakabhaka?

Ukukhanya okuluhlaza okwesibhakabhaka kunzima kakhulu kunokuba unokucinga, utshilo uSheri Rowen, MD, ugqirha wamehlo kunye nelungu leBhodi yeeNgcebiso ngezeMpilo ye-Eyesafe.

Ukukhanya kwenziwa ngamasuntswana ombane abizwa ngokuba ziifotoni ezihamba ngamaza, utshilo uGqirha Rowen. "La maza okukhanya okubonakalayo kunye nokungabonakali alinganiswa ngeenanometers (nm); i-wavelength emfutshane (kwaye ke, i-nm ephantsi yokulinganisa), iphezulu amandla."

"Iliso lomntu libona kuphela ukukhanya okubonakalayo kwesibane se-electromagnetic, esikwi-380-700 nm kwaye emelwe yimibala ye-violet, indigo, luhlaza, luhlaza, tyheli, orenji, kunye nobomvu, utshilo. "Ukukhanya okuluhlaza okwesibhakabhaka, okwaziwa ngokuba kukukhanya okuphezulu kwamandla (HEV), kunelona zinga lifutshane lokukhanya okubonakalayo (phakathi kwe-380-500 nm) kwaye ke ngoko kuvelisa owona mandla aphezulu."

Ewe, ukukhanya okuluhlaza okwesibhakabhaka kuvela kwizixhobo zakho ezininzi zedijithali, kodwa kwakhona kuvela kwezinye iindawo zokukhanya ezenziwe ngabantu (ezifana nezibane zesitrato kunye nezibane zangaphakathi) kwaye zivela ngokwemvelo ukusuka elangeni. Kungenxa yoko ukukhanya okuluhlaza okwesibhakabhaka kuthathwa njengokuyimfuneko kwimisebenzi ebalulekileyo, njengokulawula isingqi esinempilo se-circadian (ukuvuka kwendalo komzimba kunye nomjikelo wokulala), utshilo uGqirha Rowen. Kodwa kulapho imiba inokuvela khona.

Ngaba ukukhanya okuluhlaza kuyingozi emehlweni akho?

Nanku apho kuya kusiba nzima ngakumbi. Ukhe weva ukuba ukukhanya okuluhlaza okwesibhakabhaka akulunganga kwimpilo yamehlo akho. Ngapha koko, u-Ashley Katsikos, OD, i-FAAO, ingcali yamehlo eyomileyo kwiGolden Gate Eye Associates ngaphakathi kwePacific Vision Eye Institute ithi, ekuhambeni kwexesha, ukubonakaliswa kokukhanya okuluhlaza okwesibhakabhaka kwe-HEV kunokukhokelela kwingozi yexesha elide emehlweni akho, kubandakanya umonakalo onokubakho kwiiseli ze-retina, ukonakala okune-age-macular degeneration (ukonakala kwinxalenye ethile ye-retina yakho, enokukhokelela kubumfama), i-cataract zakwangoko, i-pinguecula kunye ne-pterygium Inxalenye yamehlo, enokubangela iso elomileyo, ukucaphuka, kwaye, kwixesha elide, iingxaki zombono), iliso elomileyo, kunye noxinzelelo lwamehlo kwidijithali.

Nangona kunjalo, ezinye iingcali-kunye ne-American Academy of Ophthalmology (AAO) -ukugcina ukuba, ngelixa ukugqithisa ukukhanya okuluhlaza okwesibhakabhaka kunye nemitha yokukhanya ye-UV evela elangeni kunokunyusa umngcipheko wesifo samehlo, inani elincinci lokukhanya okuluhlaza okuvela kwizikrini zekhompyutha t kubonisiwe ukuba kunokubangela nawuphi na umonakalo emehlweni akho.

"Njengokuba sinokuthi ngoku, ukukhanya okuluhlaza okwesibhakabhaka akulonakalisi iliso lomntu, njengoko uqhubeka nobomi bakho bemihla ngemihla," utshilo uSunir Garg, MD, osisithethi seklinikhi yeAmerican Academy of Ophthalmology kunye noprofesa we-ophthalmology eWills Eye Esibhedlele. "Ukukhanya okuluhlaza luhlobo lwendalo lokukhanya okukhoyo elangeni-ngaphandle, ufumana ukukhanya okuluhlaza okwesibhakabhaka ukusuka elangeni kunokuba ubuya kwenza kwisikrini sakho sefowuni, nokuba uhleli apho iiyure ezimbalwa ngosuku. Iliso lomntu usebenze kakuhle kumawakawaka eminyaka ngendaleko ekucoceni ukukhanya okuninzi okuyingozi elangeni-kwaye yamkelwe kwiifowuni okanye kwiitafile okanye kwizikrini kodwa kumanqanaba asezantsi kakhulu kunalawo akhona kwilanga lendalo. "

Oko kwathethi, ukubonwa kwakho ngokudibeneyo kwizikrini kugqithisile-abantu abaninzi babajonga iyure ngeyure, usuku nosuku, uninzi lobomi babo. Yiyo loo nto uGqirha Rowen esithi "nangona inani lokukhanya elikhutshwe zizikrini zedijithali lingaphantsi kakhulu kunelanga, ngoku sichitha ixesha elininzi phambi kwezikrini ngaphandle kokwazi iziphumo zolu nyuso lwe-radiation luphantsi amehlo. " Kwaye ngenxa yenkqubela phambili kwezobuchwephesha, imiboniso iya ikhanya ngokukhanya, kunye nokudityaniswa kwabo kubomi bemihla ngemihla kuya kusiba nzima, utshilo. Cinga ngezixhobo ze-AR/VR ezifumana ukuthandwa kunye nendlela ngokusondeleyo ziphethe isixhobo esikhupha ukukhanya esiblowu emehlweni akho.

Kubalulekile ukuba uqaphele ukuba umngcipheko wokukhanya okuluhlaza okwesibhakabhaka unokuba yinkxalabo enkulu kubantwana nakubantu abadala abancinci (abangaphantsi kweminyaka engama-20) abachaphazeleka ikakhulu ngenxa yokuba benelensi ecacileyo, kwaye kungoko ukuhluza okuluhlaza okwesibhakabhaka, utshilo uGqirha Rowen. Ngokuhamba kwexesha, njengoko i-lens kwiliso lomntu isidala, "iba tyheli ngakumbi, ngaloo ndlela ihluza uninzi lokukhanya okuluhlaza esivezwa kuko," utshilo. "Asizazi iziphumo zexesha elide zokukhanya okuphezulu, ukukhanya okuluhlaza okwesibhakabhaka kubantwana abancinci abaya kuba neminyaka engama-80 besebenzisa izixhobo zedijithali."

Luthini uphando? Ingxelo ye-2019 ye-Arhente yaseFransi yoKutya, iNdawo, kunye neMpilo yokuSebenza kunye noKhuseleko (ANSES) iqinisekisa ukuba ukubonakaliswa kwexesha elide le-retina ekukhanyeni okuluhlaza okwesibhakabhaka yinto ebangela ukuba kwenzeke ukubola kwe-retinal, ngokutsho kukaDkt Rowen. Isishwankathelo sophando ngo-2018 esipapashwe kwi- Ijenali yaMazwe ngaMazwe ye-Ophthalmology ifumene ukuba, ngelixa inani elithile lokukhanya okuluhlaza okwesibhakabhaka linokukhuthaza ukuphuhliswa kwamehlo omntu kunye nokulawula isigqi se-circadian, iziphumo ezinobungozi zokukhanya okuluhlaza zingabandakanya iqondo lomonakalo kwi-cornea, i-crystal lens, kunye ne-retina kwiso lomntu.

Nangona kunjalo, uGqirha Garg ubonelela ngempikiswano ephikisayo, esithi izifundo esele zikhona ikakhulu zijonga iigundane okanye iiseli ze-retinal eziphakanyisiweyo ezijinga kwiizitya zePetri kwaye zibandakanya ukubonakaliswa "kukukhanya okuluhlaza okwesibhakabhaka okunamandla-ngamanye amaxesha ikhulu okanye iliwaka elinamandla kunoko kunokuba kunjalo zivela kwiifowuni- kunye neeyure ekugqibeleni, ezingekho mgangathweni zibonisa ukuba ukukhanya kweblue kubangela iingxaki ebantwini, utshilo. Ngenxa yoko, kulo nyaka uphelileyo okanye kunjalo, abaphandi baye baqala ukusebenzisa imiboniso efana nabathengi njengomthombo wokukhanya kwiimvavanyo zabo ze-in-vitro kunye nokukhanya okuphantsi okufana nezo ze-digital screen in-vivo experiments kwizilwanyana kunye neeseli eziqwalaselweyo. Umomokalo ekutyhilekeni okongezelekayo, utsho uGqr. Rowen.

Intloko ijikeleza? I-takeaway: "Kuninzi ekusafuneka sikuqonde malunga neendlela zokusebenzisana kokukhanya kunye neeseli ze-retina kunye nokukwazi kwamehlo ukulungisa umonakalo ekugqibeleni," utsho uGqr Rowen. Kwaye ngoku, akukho lwanele uphando lomntu ukubonisa iziphumo zokukhanya okuluhlaza okwesibhakabhaka ngendlela emele ngokwenyani indlela esiyisebenzisa ngayo kule mihla-uyazi, ukuskrola iTikTok ebhedini nakuko konke.

Iliso elomileyo, ubunzima beLiso ledijithali, kunye neRekhodi yesiSyadiya

Xa udibanisa lonke ixesha olichitha ujonge kwizikrini, kulula ukubona ukuba kutheni ukukhanya okuluhlaza kucingelwa njengomngcipheko (emva kwayo yonke into, kakhulu nantoni na ayiqhelekanga kakuhle). Oko kwathiwa, ngelixa singaqinisekanga ngokupheleleyo ngekhonkco phakathi kokukhanya okuluhlaza kunye isifo samehlo, Zonke zontathu iingcali ziyavuma ukuba ixesha eligqithisileyo lescreen linokubangela uxinzelelo lwamehlo kwidijithali kunye / okanye iliso elomileyo, kwaye linokuphazamisa isingqi sakho sokujikeleza.

Uhlobo lwamehlo kwidijithali Yimeko echaza ukungonwabi kwamehlo ngokubanzi emva kokusetyenziswa kwescreen kwaye iboniswa ngamehlo owomileyo, iintloko, kunye nombono omdaka. (Nantsi yonke into ofuna ukuyazi malunga noxinzelelo lwamehlo edijithali.)

Iliso elomileyo inokuba luphawu lwamehlo kwidijithali, kodwa ikwabhekisa kwimeko apho umntu engenazo iinyembezi ezisemgangathweni zokuthambisa kunye nokondla iliso, ngokwe American Optometric Association. Ingabangelwa yimibono yombono (njengeelensi zonxibelelwano kunye neLASIK), iimeko zonyango, amayeza, utshintsho lwehomoni kunye nobudala. Kwaye-ewe-ukusilela ukuqhwanyaza rhoqo, njengaxa ujonge kwikhompyuter ixesha elide, kunokuba negalelo kwiimpawu zamehlo ezomileyo.

"Xa uvuka ujonge ikhompyuter iiyure kwaye amehlo akho ebuhlungu, yinto yokwenene leyo," utshilo uGqirha Garg. Kodwa loo mava awaveli kukukhanya okuluhlaza kuphela. "Xa ujonge kwiscreen ixesha elide, awukhanyisi rhoqo, ngoko amehlo akho ayoma, kwaye ekubeni ungashukumisi amehlo akho-ajonge endaweni enye kwaye angahambi- nawuphina umsebenzi onje uya kubangela ukuba amehlo akho adinwe kwaye emva koko azive ekhathaza, utshilo.

Isingqisho seSyadian iziphumo ezibangelwa ukukhanya okwesibhakabhaka nazo ziye zacelwa umngeni nangona ithiyori eyamkelwe kakuhle ukuba iphazamisa le pateni ibalulekileyo yokuvuka. Ngaphandle kwamathandabuzo, uvile "akukho xesha lesikrini ngaphambi kokulala". Ngenxa yokuba izixhobo zakho zedijithali zikhupha ukukhanya okuphezulu kwamandla aluhlaza okwesibhakabhaka (njengelanga), uphononongo lucebise ukuba ukukhanya okuluhlaza okwesibhakabhaka kakhulu ebusuku kungaphazamisa isingqi sakho sendalo, esinokubangela ukungalali kunye nokudinwa emini, ucacisa uGqr. Rowen.

Olu hlolisiso lubonisa ukuba ukukhanya okuluhlaza okwesibhakabhaka kunokuyicinezela imveliso yomzimba wakho nokukhululwa kwemvelo kwemelatonin (incindi yencindi yokulala), nto leyo enokubangela ukuphazamiseka kwemijikelo yokulala—yaye zontathu iingcali zavumelana ngoku. Nangona kunjalo, isifundo esitsha se2020 esipapashwe kwiIbhayoloji yangoku iphakamisa ukuba ukukhanya okuluhlaza okwesibhakabhaka akunatyala, ngokuchanekileyo; Abaphandi baveze iimpuku kwizibane ezinokukhanya okulinganayo ezazingafaniyo kwaye bagqiba kwelokuba ukukhanya okumthubi kubonakala ngathi kuphazamisa ukulala ngaphezu kokukhanya okuluhlaza okwesibhakabhaka. Kukho imiqolomba embalwa, ewe: ezi ziimpuku, hayi abantu, amanqanaba okukhanya ayemnyama, ngaphandle kombala, onokuthi ungakhanyisi izibane ezikhanyayo ze-elektroniki, kwaye abaphandi bajonge ngokuthe ngqo kwiicones emehlweni abo (abona umbala Endaweni ye-melanopsin, evakalelwa kukukhanya kwaye isembindini wokukhutshelwa kwe-melatonin, utshilo uGqirha Cathy Goldstein, ingcali yokulala eMichigan Medicine kudliwanondlebe kunye IXESHA.

Nangona esi sifundo sitsha sicela umngeni kukukhanya okuluhlaza okwesibhakabhaka vs. ithiyori ye-melatonin, uGqr. Rowen ugcina ukuba ubungqina obuninzi buxhomekeke kwithiyori-kwaye, ngenxa yoko, kufuneka unciphise ukukhanya okuluhlaza okwesibhakabhaka ngaphambi kokulala. "Iziphumo zophando ezininzi ezenziwa ebantwini, apho abantu babephantsi kokukhanya okuluhlaza okwesibhakabhaka kwizibane ezingezizo (iikhompyuter, iifowuni, iitafile, njl. ngokuvezwa okuphantsi kakhulu kukukhanya okuluhlaza okwesibhakabhaka, utshilo.

Ke, ngaba iiglasi eziluhlaza okwesibhakabhaka ziyasebenza?

Ngokumalunga nokucoca ukukhanya okuluhlaza, ewe, bayakwenza umsebenzi. "Iilensi zigqunywe ngezinto ezincedisa ukuhluzwa kwe-HEV blue light spectrum," utshilo uGqr Rowen.

Ukucinga ukuba yinkampani ehloniphekileyo, banokuzibetha ngokufanelekileyo ezi thagethi kwaye bacime inani lamaza ohlukeneyo, utshilo uGqirha Garg. Umzekelo, ukuba wakhe wasebenza ngeelaser kwaye kufuneka unxibe iiglasi zokhuselo ezikhethekileyo, zihlala zivimba ubude be-laser oyisebenzisayo, utshilo. Ke ayiyithandi into yokuba iphambene, itekhnoloji entsha- yiyo loo nto iiglasi zokukhanya eziluhlaza (okanye ezingafanelekanga) zingabizi mali eninzi.

"Ngokubhekiselele ekusebenzeni, imiba ephambili abantu abahlangabezana nayo ngexesha elide lesikrini yi-digital eye strain, ukuphazamiseka kokulala kwe-circadian rhythm, kunye nezinye iimpawu zokuxela ezifana neso elomileyo, intloko ebuhlungu kunye nokudinwa," kusho uDkt Rowen. Kwaye ukuba ukhe weva ngabantu abathanda iiglasi zokukhanya eziluhlaza okwesibhakabhaka, ngekhe umangaliswe kukuva ukuba "uninzi lwezigulana ziyaqaphela ukuba ziyasebenza kuba iimpawu zamehlo kunye nentloko ziyahamba nangona Abanciphisi ixesha labo lesikrini, utshilo uGqirha Katsikos.

Ukuba ufuna ukuzama isibini, ingcali yakho yokhathalelo lwamehlo sesona sixhobo sigqibeleleyo sokumisela iimfuno zakho ezithile kunye nokukunceda ekuboneni ukuba yeyiphi na eyewear efanelekileyo kwiimfuno zakho zemihla ngemihla, kunye nokudibana okanye ukugqitha kwimigangatho esemgangathweni yomzi mveliso, utshilo uGqirha Rowen. "Baninzi abavelisi abalungileyo betekhnoloji yelensi yokucoca ukukhanya okuluhlaza kwaye ngenxa yokuba iilensi zakhelwe kummiselo ukuba zifuneka, ezi lensi zenziwe ngemigangatho ephezulu yomgangatho okhoyo. Unokufuna ukubuza malunga nokunciphisa ilitha kunye neelensi ezichasene ne-reflective kunye ne-photochromic lens. ebonelela ngokhuseleko olululo kwi-UV kunye nokukhanya okuluhlaza okwesibhakabhaka ngelixa ningaphakathi nangaphandle."

Kulungile, kodwa ngaba bakhona wintetho yiyo?

Ngelixa iiglasi eziluhlaza okwesibhakabhaka ngobuchule yenza sebenza-njengakwi, benza umsebenzi wabo wokuthintela amehlo akho ekukhanyeni okuluhlaza-nokuba kufanelekile ukuthenga ngomnye umbuzo. Kuba, enyanisweni, ukuba iziphumo eziyinyani zokukhanya okuluhlaza emehlweni abantu zisephezulu emoyeni, kunjalo ke ukukwazi ukwenza iiglasi eziluhlaza ukwenza nantoni na ukunceda.

Kwaye-ukumangaliswa, ukumangaliswa-uphando kwiiglasi ngokwazo alunakulinganiswa. Uphononongo olucwangcisiweyo lwe-2017 olujonge kwizifundo ezintathu kwiziphumo zeelensi eziluhlaza-zokuvimba ukukhanya ekusebenzeni ngokubonakalayo, kwimpilo ye-macular, kunye nokujikeleza kokulala akufumananga bungqina obuphezulu bokuxhasa ukusebenzisa ezi ntlobo zeelensi.

Oko kwathiwa, ngaphandle kweendleko, akukho mngcipheko omkhulu wokuzama iiglasi ezikhanyayo eziluhlaza. Ngokuqhelekileyo akunjalo yingozi Ukunxiba iimpahla zamehlo eziluhlaza okwesibhakabhaka, kungcono ukuzinxiba kunokuba ungazinxibi, "utshilo uGqr. Katsikos. Iiglasi ezikhanyayo eziblue zingakuqhuba naphi na ukusuka kwi-17 yeedola kwi-Intanethi ukuya kwi-100 yeedola kwivenkile yamehlo ekhethekileyo. Unokongeza ubuchwephesha kwiilensi zakho ezibhalwe ngugqirha. (Nokuba i-inshurensi yakho iyabagubungela okanye hayi iya kuxhomekeka kwisicwangciso sakho sombono, apho ubathenga khona, nokuba bayahamba kwiilensi zakho zeRx okanye hayi.)

Kukho, nangona kunjalo, enye into enomdla ukuyigcina engqondweni ukuba ucinga ukuhamba ngendlela yeelensi zeRx: amandla anokubakho umva Iziphumo zokukhanya kweiglasi eziluhlaza okwesibhakabhaka kunokuba nesingqisho sakho se-circadian- ngakumbi ukuba ukhetha ukubeka icebo lokucoca ukukhanya okuluhlaza okwesibhakabhaka kwiiglasi oceba ukuzinxiba kuzo zonke iiyure zakho zokuvuka. "Ukuba uvimba ukukhanya okuluhlaza ngalo lonke ixesha emini okanye ebusuku, oko kunokuba nefuthe elibi kwinto esiyibiza ngokuba kukungena kwisingqisho se-circadian," aka ungqamaniso lwesingqisho sakho se-circadian kunye neendlela zangaphandle, utshilo uGqr. Garg. Ukuba ngequbuliso unxibe iiglasi zokukhanya eziluhlaza okwesibhakabhaka imini yonke, umzimba wakho unokucinga ukuba, "kuya kuba nini imini?" uthi. "Ngokuvela kwindalo, sele siqhele ukukhanya okuluhlaza okwesibhakabhaka ukunceda ukugcina isingqisho sokhuseleko, kwaye ukuba oko kuyadlula, kunokuba neziphumo ezibi nazo."

Ngethamsanqa, eyona nto ilula onokuyenza ukulwa noxinzelelo lwamehlo edijithali, iliso elomileyo, kunye nokudinwa kwamehlo ngenxa yexesha lesikrini kukuqhelisela imithambo yamehlo elula kwaye uthathe ikhefu rhoqo ngelixa usebenza phambi kwekhompyuter okanye ujonge kwenye. isikrini. UGqr. Garg ucebisa umthetho we-20/20/20: Rhoqo kwimizuzu engama-20, thatha ikhefu lemizuzwana engama-20, kwaye ujonge iinyawo ezingama-20 ukude. "Oko kuyakukunyanzela ukuba ushukumise amehlo akho, kwaye iyakunceda ukuthambisa amehlo akho," utshilo.

Kwaye enye into ebaluleke kakhulu ekufuneka uyikhumbule? Rhoqo, kwihlabathi lempilo-ntle, ezona ndlela zilula zokukhathalela impilo yakho zihamba ziye phambili. Kuzo zonke izinto ezahlukeneyo onokuthi uzenze kwimpilo yakho kunye nokuba sempilweni, andiqondi ukuba oku kufanele ukuba kube phezulu kuluhlu lwakho lwenkxalabo, utshilo uGqr. Garg. "Ukhathazekile ngokugcina ukutya okufanelekileyo, ungatshayi, kwaye wenze umthambo ophakathi. Ezi zinto ngokuqinisekileyo ziya kunceda ukugcina amehlo akho esempilweni."

Uphengululo lwe
