Ukuchitha isikhathi esiningi nsuku zonke phambi kwekhompyutha, ithebhulethi, noma umakhalekhukhwini kungabangela izimpawu ze-computer visual syndrome (CVS) noma i-digital eyestrain.Abantu abaningi babhekana nalokhu kukhathala kwamehlo nokucasuka.Izibuko zekhompyutha ziyizibuko eziklanyelwe ngokukhethekile ukusebenza ngokunethezeka ekhompyutheni yakho noma ngenkathi usebenzisa amanye amadivaysi edijithali.
I-Computer vision syndrome kanye ne-digital eye strain
I-CVS iqoqo lezimpawu ezibangelwa ukusetshenziswa isikhathi eside kwekhompyutha noma idivayisi yedijithali.Izimpawu zihlanganisa ukuqina kwamehlo, iso elomile, ikhanda elibuhlungu, nokungaboni kahle.Abantu abaningi bazama ukunxephezela lezi zinkinga zokubona ngokuncika phambili noma babheke phansi kwezibuko zabo.Lokhu kuvame ukudala ubuhlungu beqolo namahlombe.
Izimpawu zivela ngoba kungase kube nebanga, ukuxhopha, ukukhanya okunganele, noma izinkinga zokukhanya kwesikrini phakathi kwamehlo nengqondo.Ukugxila isikhathi eside esikrinini ebangeni elithile ngesikhathi kungabangela ukukhathala, ukukhathala, ukoma, nomuzwa oshisayo.eyodwa
Izimpawu
Abantu abane-CVS bangase babe nalezi zimpawu ezilandelayo:
•Iso Elomile
•Ikhanda elibuhlungu
•Ukucasuka kwamehlo
•Ukubona lufifi
•Ukuzwela ekukhanyeni
•Okwesikhashana ayikwazi ukugxila ezintweni ezikude (pseudomyopia noma i-accommodative seizures)
•I-Diplopia
•Ukucweba amehlo
•Ubuhlungu bentamo namahlombe
Ungase ube ne-eyestrain yedijithali ngenkathi usebenzisa iselula noma ithebhulethi yakho, kodwa inkinga efanayo ayenzeki esikrinini sekhompyutha yakho.Sivamise ukuba nomakhalekhukhwini namathebulethi eduze kwamehlo ethu, ngakho-ke la madivayisi angabona lokhu ngaphezu kwezikrini zekhompyutha, ezivame ukuba kude.
Izimpawu ze-CVS zingabangelwa i-presbyopia, ukuphazamiseka kombono okukhula ngokukhula.I-Presbyopia ukulahlekelwa ikhono leso lokushintsha ukugxila ukuze libone izinto eziseduze.Ngokuvamile kubonakala cishe eminyakeni engama-40
Indlela yokubhekana nayo
Uma unezinkinga zamehlo ngenkathi usebenzisa ikhompuyutha yakho, amathiphu alandelayo kufanelekile ukuzama.
•Cabanga ngezibuko zekhompyutha
•Blink, phefumula futhi ume.Gcwayiza kaningi, phefumula kakhulu, thatha ikhefu elifushane njalo ngehora
•Sebenzisa izinyembezi zokwenziwa ukuze uthole amehlo omile noma alumayo.
•Lungisa ileveli yokukhanya ukuze unciphise ukuxhopha okuvela esikrinini.
•Khulisa usayizi wefonti wesikrini sekhompyutha yakho
Umthetho we-20/20/20 uwusizo nasekusetshenzisweni kwesikhathi eside kwamadivayisi anezibonisi.Njalo ngemizuzu engama-20, thatha imizuzwana engama-20 ukuze ubheke ukusuka kumafidi angama-20 (ngaphandle kwefasitela, ngemuva kwehhovisi / indlu yakho, njll.).
Futhi, ama-ergonomics amahle njengobude obufanele besikrini (ukubheka ngqo phambili ngaphandle kokusikisela phezulu naphansi) nokusebenzisa isitulo esingcono esinokusekelwa kwe-lumbar kungakusiza ukuthi ubhekane nenkinga.Ukukhathala okubonakalayo kwedijithali.
Indlela Izibuko Zekhompyutha Zingasiza Ngayo
Uma ucabanga ukuthi unezinye zezimpawu ze-CVS, ungase uzuze ezingilazini zekhompyutha.Ngezibuko zekhompiyutha, yonke ilensi igxile ebangeni elifanayo, futhi akudingekile ukuthi utshekise ikhanda lakho ukuze ubuke isikrini sekhompyutha.
Umsebenzi wekhompyutha uhilela ukugxilisa amehlo ebangeni elifushane.Izikrini zekhompyutha zivame ukubekwa phambili kancane kunebanga lokufunda elinethezekile, ngakho-ke izibuko zokufunda ezijwayelekile ngokuvamile azanele ukudambisa izimpawu ze-CVS.Izibuko zekhompyutha zenza kube lula kumuntu ukuthi agxile ebangeni elisuka kusikrini sekhompyutha.
Abafake amalensi okuxhumana kungase kudingeke bagqoke izibuko kwabathintana nabo lapho besebenzisa ikhompuyutha.
Izinkinga zokubona ngekhompyutha zenzeka nakubantu abasha, ngakho-ke i-CVS akuyona inkinga ekhona kuphela kubantu abangaphezu kweminyaka yobudala engama-40. I-CVS isiba isikhalazo esivamile kuwo wonke amaqembu eminyaka yobudala.
Uma uchitha amahora angaphezu kwamane nsuku zonke phambi kwekhompyutha yakho, ngisho nezinkinga ezincane zokubona ezingalungiswanga zingaba zimbi kakhulu.
Uzithola kanjani izibuko zekhompyutha
Udokotela wakho noma udokotela wamehlo angase akunikeze izibuko zekhompyutha ukusiza ukukhulula izimpawu ze-CVS.
Bheka indawo yakho yokusebenza ngaphambi kokubhuka.Kubalulekile ukuthi umhlinzeki wakho wokunakekelwa kwezempilo azi kahle ukuthi indawo yakho yokusebenza imiswe kanjani, njengebanga phakathi kwemonitha yakho namehlo akho, ukuze akwazi ukukuyalela izibuko zekhompyutha ezifanele.
Naka futhi ukukhanyisa.Ukukhanya okukhanyayo kuvame ukudala i-eyestrain ehhovisi.4 ama-anti-reflective (AR) angasetshenziswa kwilensi ukuze kuncishiswe inani lokuxhopha kanye nokukhanya okubonisiwe okufinyelela emehlweni.
Izinhlobo zamalensi ezingilazi zekhompyutha
Amalensi alandelayo aklanyelwe ukusetshenziswa ikhompuyutha ngokukhethekile.
•Ilensi yombono owodwa - Ilensi yombono eyodwa wuhlobo olulula lwengilazi yekhompyutha.Ilensi yonke iklanyelwe ukubheka isikrini sekhompyutha, ihlinzeka ngomkhakha wokubuka obanzi kakhulu.Bobabili abadala kanye nezingane bayawathanda lawa ma-lens ngoba umshini ubukeka ucacile futhi ungavimbeki.Nokho, izinto ezikude noma eziseduze kunesikrini sekhompyutha yakho zizovela zifiphele.
•I-Flat-top bifocals: I-Flat-top bifocals ibukeka njengama-bifocal avamile.Lawa ma-lens aklanywe ngendlela yokuthi ingxenye engaphezulu yelensi ilungise ukuze igxile kusikrini sekhompyutha futhi ingxenye engezansi ilungise ukuze igxile ekufundeni okuseduze.Lawa ma-lens anomugqa obonakalayo ohlukanisa izingxenye ezimbili zokugxila.Lawa ma-lens ahlinzeka ngokubukeka okunethezekile kwekhompyutha yakho, kodwa izinto ezikude zibonakala zilufifi.Ukwengeza, into ebizwa ngokuthi "ukweqa uhlaka" ingase yenzeke.Lesi isenzakalo esenzeka lapho isibukeli sisuka kwenye ingxenye yelensi siye kwenye futhi isithombe sibonakala “sigxuma”.
•I-Varifocal - Abanye ochwepheshe bokunakekelwa kwamehlo babiza le lensi ngokuthi "ikhompyutha eqhubekayo".Nakuba kufana ngomklamo namalensi wendabuko angenalayini aqhubekayo aqhubekayo, amalensi e-varifocal acace kakhulu kumsebenzi ngamunye.Le lens inengxenye encane phezulu kwelensi ebonisa izinto ezikude.Ingxenye enkulu emaphakathi ibonisa isikrini sekhompyutha, futhi ekugcineni ingxenye encane engezansi kwelensi ibonisa ilensi.Gxila ezintweni eziseduze.Lezi zingaphinda zidalwe phezulu ngebanga elimisiwe ukusuka kusikrini sekhompyutha esikhundleni sokubuka okukude.Lolu hlobo lwamalensi alunayo imigqa noma amasegimenti abonakalayo, ngakho lubukeka njengokubona okuvamile.
Ukulingana okuhle kuyisihluthulelo
Izibuko zekhompyutha zingazuzisa abasebenzisi bamakhompyutha uma zigqokwe futhi zibhalwe ngendlela efanele.
Odokotela bamehlo kanye nodokotela bamehlo bazazi kahle izinkinga ezibangelwa yi-computer vision syndrome futhi bangakusiza ukuthi uthole ipheya efanele.
