Ukuchitha ixesha elininzi imihla ngemihla phambi kwekhompyutheni, ithebhulethi, okanye ifowuni yeselula inokubangela iimpawu ze-computer visual syndrome (CVS) okanye i-digital eyestrain.Abantu abaninzi bafumana oku kudinwa kwamehlo kunye nokucaphuka.Iiglasi zekhompyuter ziiglasi eziyilelwe ngokukodwa ukusebenza ngokukhululeka kwikhompyuter yakho okanye ngelixa usebenzisa ezinye izixhobo zedijithali.
I-Computer vision syndrome kunye ne-digital eye strain
I-CVS yingqokelela yeempawu ezibangelwa kukusetyenziswa ixesha elide kwekhompyutha okanye isixhobo sedijithali.Iimpawu ziquka ukuqina kwamehlo, iso elomileyo, intloko ebuhlungu, kunye nokungaboni kakuhle.Abantu abaninzi bazama ukuhlawulela ezi ngxaki zombono ngokungqiyama okanye bajonge emazantsi eeglasi zabo.Oku kudla ngokubangela iintlungu zomqolo namagxa.
Iimpawu zivela ngenxa yokuba kusenokubakho umgama, ilitha, ukukhanya okunganelanga, okanye iingxaki zokuqaqamba kwesikrini phakathi kwamehlo nengqondo.Ukugxila ixesha elide kwisikrini kumgama othile ngexesha kunokubangela ukudinwa, ukudinwa, ukoma, kunye nokutshisa.Nye
Iimpawu
Abantu abane-CVS banokufumana ezi mpawu zilandelayo:
•Iliso elomileyo
•Intloko ebuhlungu
•Ukucaphuka kwamehlo
•Ukungaboni kakuhle
•Uvakalelo ekukhanyeni
•Okwexeshana awukwazi ukugxila kwizinto ezikude (pseudomyopia okanye i-accommodative seizures)
•IDiplopia
•Ukuncwina amehlo
•Intamo kunye neentlungu zegxalaba
Unokufumana i-eyestrain yedijithali ngelixa usebenzisa iselfowuni okanye ithebhulethi yakho, kodwa ingxaki efanayo ayenzeki kwiscreen sekhompyuter yakho.Sidla ngokuba neefowuni eziphathwayo kunye neetafile ezikufutshane namehlo ethu, ke ezi zixhobo zinokuqaphela oku ngaphezu kwezikrini zekhompyuter, ezihlala zikude.
Iimpawu ze-CVS zinokubangelwa yi-presbyopia, ingxaki yombono ekhula ngeminyaka.I-Presbyopia kukulahlekelwa ukukwazi kwamehlo ukutshintsha ukugxila ekuboneni izinto ezikufutshane.Ngokuqhelekileyo kubonakala malunga neminyaka engama-40
Indlela yokujongana nayo
Ukuba uneengxaki zamehlo ngelixa usebenzisa ikhompyuter yakho, ezi ngcebiso zilandelayo zifanelekile ukuzama.
•Cinga ngeendondo zekhompyutha
•Ukuqhwanyaza, phefumla kwaye uyeke.Ukuqhwanyaza rhoqo, phefumla ngokunzulu rhoqo, thatha ikhefu elifutshane rhoqo ngeyure
•Sebenzisa iinyembezi zokwenziwa kumehlo omileyo okanye arhawuzelelayo.
•Lungisa inqanaba lokukhanya ukunciphisa ilitha kwiscreen.
•Yandisa ubungakanani befonti yesikrini sekhompyuter yakho
Umgaqo we-20/20/20 uluncedo nakwixesha elide lokusetyenziswa kwezixhobo ezineziboniso.Rhoqo ngemizuzu engama-20, thatha imizuzwana engama-20 ukujonga ukusuka kwiimitha ezingama-20 (ngaphandle kwefestile, emva kweofisi / indlu yakho, njl. njl.).
Kwakhona, i-ergonomics efanelekileyo efana nobude obufanelekileyo besikrini (ukukhangela ngqo phambili ngaphandle kokuphakamisa naphantsi) kunye nokusebenzisa isitulo esingcono kunye nenkxaso ye-lumbar kunokukunceda ukujongana nale ngxaki.Ukudinwa okubonakalayo kwedijithali.
Iiglasi zeKhompyutha zinganceda njani
Ukuba ucinga ukuba ufumana ezinye zeempawu ze-CVS, unokuxhamla kwiiglasi zekhompyuter.Ngeeglasi zekhompyuter, i-lens yonke igxile kumgama ofanayo, kwaye akufuneki ubuyisele intloko yakho umva ukujonga isikrini sekhompyuter.
Umsebenzi wekhompyuter ubandakanya ukujolisa amehlo kumgama omfutshane.Izikrini zekhompyuter zibekwe ngokubanzi kumgama ongaphezulu kunomgama wokufunda okhululekileyo, ngoko ke iiglasi zokufunda eziqhelekileyo azanelanga ukuthomalalisa iimpawu zeCVS.Iiglasi zekhompyuter zenza kube lula ukuba umntu agxile kumgama ukusuka kwiscreen sekhompyuter.
Abanxibe iilensi zoqhagamshelwano banokufuna ukunxiba iindondo kubafowunelwa babo xa besebenzisa ikhompyutha.
Iingxaki zombono weKhompyutha ziyenzeka nakulutsha, ngoko ke i-CVS asiyongxaki ekhoyo kuphela kubantu abangaphezulu kweminyaka engama-40.
Ukuba uchitha ngaphezulu kweeyure ezine yonke imihla phambi kwekhompyuter yakho, nokuba zincinci, iingxaki zombono ezingalungiswanga zinokuba nzulu ngakumbi.
Uzifumana njani iiglasi zekhompyuter
Ugqirha wakho okanye ugqirha wamehlo unokukuyalela iiglasi zekhompyuter ukunceda ukuthomalalisa iimpawu ze-CVS.
Jonga indawo yakho yokusebenza phambi kokuba ubhukishe.Kubalulekile ukuba umboneleli wakho wezempilo azi kakuhle ukuba indawo yakho yokusebenza imiswe njani, njengomgama phakathi kwemonitha yakho kunye namehlo akho, ukuze bakwazi ukumisela iiglasi zekhompyuter ezifanelekileyo.
Kwakhona nikela ingqalelo ekukhanyeni.Ukukhanya okukhanyayo kudla ngokubangela ukuba i-eyestrain eofisini.I-4 i-anti-reflective (AR) i-coatings ingasetyenziswa kwi-lens ukunciphisa ubuninzi be-glare kunye nokukhanya okubonakalayo okufikelela emehlweni.
Iintlobo zeelensi zeeglasi zekhompyuter
Ezi lensi zilandelayo ziyilelwe ngokukodwa ukusetyenziswa kwikhompyutha.
•Ilensi yombono omnye-Ilensi yombono omnye lolona hlobo lulula lweglasi yekhompyuter.Ilensi iyonke yenzelwe ukujonga iscreen sekhompyuter, ibonelela ngeyona ndawo ibanzi yokujonga.Bobabini abantu abadala kunye nabantwana bayayithanda le lens kuba i-monitor ibonakala icacile kwaye ingabonakali.Nangona kunjalo, izinto ezikude okanye ezikufutshane kunescreen sekhompyuter yakho ziya kubonakala zimfiliba.
•I-Flat-top bifocals: I-Flat-top bifocals ibonakala njenge-bifocals eqhelekileyo.Ezi lens ziyilwe ukwenzela ukuba isiqingatha esiphezulu se-lens silungelelanise ukugxila kwikhompyutheni yekhompyutheni kunye necandelo elisezantsi lilungelelanisa ukugxila ekufundeni okukufutshane.Ezi lens zinomgca obonakalayo owahlula amacandelo amabini ekugxilwe kuwo.Ezi lens zibonelela ngembono etofotofo yekhompyuter yakho, kodwa izinto ezikude zibonakala zimfiliba.Ukongeza, into ebizwa ngokuba yi "frame skipping" inokwenzeka.Le yinto eyenzekayo xa umbukeli eshukuma ukusuka kwenye indawo yelensi ukuya kwenye kwaye umfanekiso ubonakala “uxhumaxhuma.”
•I-Varifocal - Ezinye iingcali zokunakekelwa kwamehlo zibiza le lens "ikhompyutheni eqhubekayo" lens.Nangona kufana kuyilo kwiilensi zemveli ezingenamgca ezingabonakaliyo eziqhubekayo, iilensi ze-varifocal zithe ngqo ngakumbi kumsebenzi ngamnye.Le lens inecandelo elincinci phezulu kwilensi ebonisa izinto ezikude.Icandelo elikhulu eliphakathi libonisa isikrini sekhompyutheni, kwaye ekugqibeleni icandelo elincinci elisezantsi kwi-lens libonisa i-lens.Gxininisa kwizinto ezikufutshane.Ezi zisenokwenziwa ngaphezulu ngomgama obekiweyo ukusuka kwiscreen sekhompyuter endaweni yokujonga kude.Olu hlobo lwelensi alunayo imigca ebonakalayo okanye amacandelo, ngoko kubonakala ngathi umbono oqhelekileyo.
Ukufaneleka kakuhle ngundoqo
Iiglasi zekhompyuter zinokuba luncedo kubasebenzisi bekhompyuter ukuba zinxitywe kwaye zimiselwe ngokufanelekileyo.
Optometrists kunye nee-ophthalmologists bazazi kakuhle iingxaki ezibangelwa yi-computer vision syndrome kwaye banokukunceda ufumane isibini esifanelekileyo.
