Ingabe amehlo akho akhathele ukubuka ikhompyutha noma ifoni? Ake sixoxe nge-(Computer Vision Syndrome)!

Ingabe uchitha ingxenye enkulu yosuku lwakho phambi kwekhompyutha? Noma efonini yakho? Ingabe amehlo akho azizwa ekhathele kakhulu futhi ebuhlungu ngaleso sikhathi? Mhlawumbe nekhanda lakho liyabuhlungu. Uma uzizwa ungakhululekile, lokhu kuyinto ebaluleke kakhulu kuwe.

Iyini i-Computer Vision Syndrome?

Kalula nje, `(Computer Vision Syndrome)` ibhekisela eqoqweni lokungakhululeki okwenzeka emehlweni nasemzimbeni wethu lapho sibheka 'amadivayisi edijithali' njengamakhompyutha, amaphilisi, nama-smartphone isikhathi eside. Lokhu kubizwa nangokuthi `(Digital Eye Strain).` Cabanga ngale ndlela, amehlo ethu afana namakhamera amabili. Uma senza into efanayo ngokuphindaphindiwe, nawo azizwa ekhathele, akunjalo? Yilokho okwenzekayo.

Ungase ube nezimpawu ezifana nobuhlungu bamehlo, ukulunywa, amehlo anamanzi, ukubona okufiphele, ubunzima bokubheka ukukhanya, kanye nekhanda elibuhlungu. Lesi akusona isimo esibucayi, kodwa singaphazamisa kakhulu imisebenzi yansuku zonke. Ngezinye izikhathi, lezi zimpawu zingaba zimbi kakhulu kangangokuthi awukwazi ngisho nokusebenza.

Sivame kangakanani lesi simo?

Eqinisweni, lesi `(Computer Vision Syndrome)` siyinkinga abantu abaningi abanayo emhlabeni wonke manje. Ucwaningo lubonisa ukuthi abantu abangaphezu kwezigidi ezingu-60 emhlabeni bahlushwa yilesi simo. Ikakhulukazi ngesikhathi sobhubhane lwe-Covid, abantu abaningi bathembele 'kumadivayisi edijithali' ukuze basebenze ekhaya, bafunde, futhi bakhulume nabangani. Ngakho-ke, lesi simo sikhule kakhulu. Ngokusho kweminye imibiko, cishe abantu abadala abangu-78% bahlushwe yi-`(Computer Vision Syndrome)` ngalesi sikhathi.

Ngisho nezingane ezincane ziyawela kulokhu. Ngokungafani nakuqala, manje zisebenzisa amafoni namathebulethi ezintweni ezifana namakilasi 'aku-inthanethi', imidlalo, kanye nokubuka amakhathuni. Ngakho-ke, lesi simo sesikhuphuke safinyelela cishe ku-50% - 60% phakathi kwezingane.

Ziyini izimpawu zalokhu?

Ake sibheke izimpawu ezivame kakhulu ze-"Computer Vision Syndrome".

Ukungakhululeki kwamehlo

• Ukungakhululeki kwamehlo: Lokhu kuyinto abantu abaningi ababhekana nayo. Kungafaka phakathi amehlo omile, ukudabuka, ukulunywa, ukusha, noma umuzwa wokuthi kukhona isihlabathi esweni.
• Umbono ofiphele: Ngokungazelelwe, izinto ziyaba zingaqondakali, bese ziphinde zicace ngemva kwesikhashana. Lokhu kungenzeka ikakhulukazi uma ubheka eduze bese ubheka kude, noma uma ubheka phansi ubheke kude bese ubheka eduze.
• Ukuzwela ukukhanya okukhulu: Kuzwakala kunzima ukubheka ukukhanya okukhulu.
• Ubunzima bokugcina amehlo akho evulekile.
• Ikhanda elibuhlungu: Ikhanda elibuhlungu, ikakhulukazi elivela ngemuva kwamehlo.

Ubuhlungu kwezinye izingxenye zomzimba ngaphandle kwamehlo

Ngokuvamile, abantu abane-"Computer Vision Syndrome" nabo bazwa ubuhlungu kwezinye izingxenye zomzimba. Isizathu salokhu ukuthi sihlala phambi kwekhompyutha ngesimo esingalungile, noma sicindezela intamo yethu ukuze sibheke "isikrini." Yingakho:

• Ubuhlungu bentamo
• Ubuhlungu behlombe
• Ukuhlungu obusemhlane

Izinto ezinjalo zingenzeka.

Kungani lokhu `(Computer Vision Syndrome)` kwenzeka?

Isizathu esiyinhloko ukuthi sichitha amahora amaningi sibheke 'izikrini' 'zamadivayisi edijithali'. Ezinye izifundo ziphakamisa ukuthi ngisho nokubheka 'isikrini' amahora amabili ngesikhathi kungabangela lezi zimpawu. Uma uchitha isikhathi esiningi ubheke 'isikrini', kulapho amathuba okuba ubhekane nalezi zinkinga enyuka khona.

Akukhona nje ukubuka isikrini. Ngisho noma sibheka into eseduze nathi, njengencwadi, amehlo ethu azizwa ekhathele isikhathi eside. Kodwa uma sibheka isikrini, lokhu kukhathala kukhulu nakakhulu. Kunezizathu eziningana zalokhu:

• Ukushintsha njalo i-'Focus': Ubuwazi ukuthi izinhlamvu nezithombe 'ezisesikrinini' zenziwe ngamachashazi amancane kakhulu abizwa ngokuthi 'amaphikseli'. Ngakho-ke, amehlo ethu kufanele ashintshe njalo i-'focus' lapha nalaphaya ukuze abone lokhu ngokucacile. Uma siqhubeka nokuhambisa amehlo ethu kanje, amehlo ethu ayakhathala.
• Izinga elithi `Contrast` le-`Screen`: Ngokuvamile, umehluko ocacile `(contrast)` phakathi kombhalo oku-`Screen` kanye ne-`(background)` yawo uphansi. Khona-ke amehlo ethu kufanele asebenze kanzima ukuze aqaphele umbhalo.
• Ukuncipha kokucwayiza: Ngokwesilinganiso, sicwayiza cishe izikhathi ezingu-18 kuya kwezingu-22 ngomzuzu. Lokhu kubaluleke kakhulu ukuthi amehlo athole umswakama odingekayo (ukugcoba). Kodwa ngokumangalisayo, uma sibheka ikhompyutha noma ifoni, inani lokucwayiza liyehla liye izikhathi ezingu-3-7 ngomzuzu! Ngezinye izikhathi asivali ngisho namehlo ethu ngokuphelele futhi sicwayize. Uma singacwayizi kahle, ubuso bamehlo buqala ukoma.

Ubani osengozini enkulu yokuthuthukisa lokhu?

Uma usebenzisa ikhompyutha noma enye idivayisi yedijithali isikhathi esingaphezu kwamahora amane ngosuku, usengozini enkulu yokuthola i-Computer Vision Syndrome.

Futhi, uma unezinye zalezi zimo, izimpawu zingase zibe zimbi kakhulu:

• Uma usuvele unesifo samehlo esomile .
• Amaphutha Okubuyisa Umbono, okusho ukuthi izimo ezifana nokubona eduze, azilungiswa kahle.
• Uma unesifo samehlo esithinta ikhono lamehlo lokugxila, isibonelo, isimo esifana nokuntuleka kokuqonda .

Ukubona kanjani lokhu?

Ukuze uxilonge `(Computer Vision Syndrome)`, kufanele nakanjani ubonane nochwepheshe wokunakekelwa kwamehlo . Uzohlola amehlo akho ngokucophelela futhi akubuze imibuzo embalwa. Angase akunike `ifomu` okufanele uligcwalise, elingabuza izinto ezifana nalezi:

• Ziyini izimpawu zakho?
• Zivame kangakanani lezi zimpawu?
• Zimbi kangakanani?

Uma unikeza udokotela imininingwane eminingi, kuzoba lula ngaye ukuthola lesi simo ngokunembile.Ngakho-ke, tshela udokotela wakho ngesikhathi osichitha usebenzisa amadivayisi edijithali, indawo osebenza kuyo, indlela ohlala ngayo, noma yiziphi ezinye izimo zezokwelapha onazo, imithi oyiphuzayo, kanye nanoma yiziphi izifo zamehlo ezinazo noma ubani emndenini wakho.

Uma udokotela ethola ukuthi une-"Computer Vision Syndrome", uzobe esekhuluma nawe ngokwelashwa.

Singayiqeda kanjani le `(Computer Vision Syndrome)`? (Ukwelashwa)

Uma silapha lokhu, sigxila ezintweni ezintathu eziyinhloko:

• Ukulawula amehlo omile.
• Ukulungisa umbono wakho.
• Ukushintsha indlela osebenza ngayo kanye nendawo ohlala kuyo.

Udokotela wakho uzonquma ukuthi yiziphi izindlela ezikufanele. Kungase kudingeke usebenzise eziningana zalezi zindlela ngesikhathi esisodwa.

Ukulawula amehlo omile

Kuvamile ukuthi amehlo akho ome uma usebenzisa amadivayisi edijithali njalo. Lokhu kungaholela esifweni samehlo esomile, noma kube kubi kakhulu ezimweni ezikhona. Ukwelashwa kuhilela ukuthambisa amehlo akho nokunciphisa ukungakhululeki. Udokotela wakho angase akuncome okulandelayo:

• Izinyembezi Zokwenziwa: Lezi uhlobo lweconsi lamehlo elingathengwa emakhemisi. Zisetshenziselwa ukwengeza umswakama emehlweni.
• Amathiphu Okucwayiza Kakhulu: Cishe awuqapheli nokuthi uchitha isikhathi esingakanani ubheke isikrini sakho ngaphandle kokucwayiza. Ngokwenza umkhuba wokucwayiza ngamabomu, ungasiza amehlo akho ukuba aphole ngezinyembezi ezivela emehlweni akho.
• Amaconsi amehlo noma ezinye izindlela zokwelapha ezinqunywe udokotela.

Ukulungisa umbono wakho

Uma unephutha elincane nje lokubona izinto ngendlela engabonakali, kungenza izimpawu ze-Computer Vision Syndrome zibe zimbi kakhulu. Ngakho-ke, udokotela wakho angancoma izibuko noma amalensi okuxhumana ukuze akusize ubone kahle.

Abanye abantu bathola uhlobo lwezibuko olubizwa ngokuthi ``Izibuko Zekhompyutha`` luwusizo kakhulu. Lezi zibuko zilungisa umbono wakho ukuze zikuvumele ukuthi ubone izinto ezikude (okungukuthi, hhayi eduze njengencwadi, kodwa hhayi kude njenge-TV), njenge-``isikrini`` sekhompyutha, ngokucacile. Uma ufuna, ungakhetha namalensi anobuchwepheshe ``bokulwa nokukhanya`` okunciphisa ukukhanya okuvela ``esikrinini.

Kungenzeka ukuthi uke wezwa ngezibuko ezivimba "ukukhanya okuluhlaza okwesibhakabhaka." Kodwa ucwaningo alukakafakazeli ukuthi lezi zinezinzuzo ngempela. Ngakho-ke uma ufuna ukusebenzisa izibuko ezinjalo, kungcono ukukhuluma nodokotela wakho ngakho.

Ukushintsha indlela osebenza ngayo kanye nendawo ohlala kuyo

Udokotela uzokweluleka ngokuthi ungayilungisa kanjani imikhuba yakho nendawo ohlala kuyo uma usebenzisa amadivayisi edijithali. Uzokubuza imibuzo mayelana nokuthi uhlala kanjani, ukuthi uchitha isikhathi esingakanani ubheka idivayisi, kanye nokukhanya ekamelweni. Lezi zinguquko ezincane zingenza umehluko omkhulu ezimpawini zakho.

Nazi ezinye izinto ezivamile ongazenza:

• Nciphisa isikhathi sokusebenzisa isikrini: Zama ukusebenzisa amadivayisi edijithali isikhathi esingaphansi kwamahora amane ngosuku uma kungenzeka.
• Thatha ikhefu njalo: Uma ungumuntu othembela kumadivayisi edijithali ngomsebenzi noma ezinye izizathu, thatha ikhefu lemizuzu eyi-15 njalo emahoreni amabili. Ungabheki noma yisiphi isikrini phakathi naleso sikhathi. Futhi, nikeza amehlo akho ikhefu ekubukeni izinto eziseduze, bese ulandela umthetho we-20-20-20 . Lokho kusho ukuthi, njalo ngemizuzu engama-20, bheka into eqhele ngamamitha angama-20 cishe imizuzwana engama-20.
• Thola indawo ekhululekile: Dala indawo yokusebenza ehlelekile , okusho indawo ekhululekile emzimbeni wakho. Lokhu kunganciphisa ukucindezeleka kwamehlo okubangelwa ukugoba phambili noma ukugoba intamo yakho ngenkathi ubheka isikrini.
• Nciphisa ukukhanya nokukhanya: Ukukhanya okukhanyayo okuvela emafasiteleni nezibani ezikhanyayo kungakhanyisa isikrini sekhompyutha yakho futhi kubangele ukukhathala kwamehlo. Vala amafasitela uma kukhona ukukhanya kwelanga okunamandla okuphuma emafasiteleni. Sebenzisa ama-bulb anamandla aphansi ezibanini eziseduze nekhompyutha yakho, futhi ugweme izibani ezikhanyayo eziphezu kwendlu.
• Lungisa ukukhanya nokugqama kwesikrini sakho: Ukukhanya kwesikrini sakho kufanele kulungiswe kuye ngezinga lokukhanya ekamelweni. Lokhu kusho ukuthi kuzodingeka ulungise ukukhanya kwesikrini sakho kuye ngesikhathi sosuku. Ukugcina ukugqama ku-60% - 70% kuyathandeka emehlweni.
• Yenza ifonti ibe nkulu: Ungazami ukufunda amafonti amancane kakhulu. Uma ifonti ingenawo ngisho `usayizi 12`, zama ukuyisondeza. Futhi, noma nini lapho kungenzeka, lungisa `izilungiselelo` ukuze ufunde amafonti amnyama `emuva elikhanyayo` (umbhalo omnyama).

Ungazivikela kanjani ku-`(Computer Vision Syndrome)`?

Eqinisweni, amathiphu amaningi okushintsha indlela yakho yansuku zonke kanye nendawo ohlala kuyo ezindleleni zokwelapha esixoxe ngazo ngenhla angakusiza futhi ekuvikeleni kule `(Computer Vision Syndrome)`.

Kungaba nzima ukuvimbela ukukhathala kwamehlo, njenge-"Computer Vision Syndrome", ngoba sithembele "kumadivayisi edijithali" emsebenzini, ekuzijabuliseni nasekuhlanganeni nabantu. Kodwa ukuthatha ikhefu nokunakekela amehlo akho kakhudlwana kungasiza kakhulu ekunciphiseni ingozi yalezi zimpawu ezicasulayo nezivamile.

Ingabe `(I-Computer Vision Syndrome)` izolulama ngokuphelele?

Ezimweni eziningi, izimpawu ziyanyamalala uma unciphisa isikhathi sakho sokubuka isikrini. Kodwa-ke, uma usebenzisa amadivayisi edijithali njalo, izimpawu zingase zibuye noma zibe zimbi kakhulu. Khuluma nodokotela wakho ngendlela yokuphatha lesi simo isikhathi eside, ikakhulukazi uma umsebenzi wakho udinga ukuthi usebenzise ikhompyutha isikhathi eside.

Kunini lapho kufanele sifune khona iseluleko sezokwelapha?

Kungumqondo omuhle ukubona udokotela wamehlo okungenani kanye ngonyaka ukuze ahlolwe amehlo akho. Ngaleyo ndlela, ungafunda ngempilo yamehlo akho jikelele futhi uxoxe nganoma yiziphi izinkinga ongase ube nazo.

Kodwa, esimweni esinjengalesi, kufanele ubonane nodokotela ngaphandle kokulinda unyaka wonke:

• Uma kuvela izimpawu ezintsha ze-`(Computer Vision Syndrome)`.
• Uma izimpawu ziba zimbi naphezu kokwelashwa.

Yimiphi imibuzo okufanele uyibuze udokotela wakho?

Uma ungumsebenzisi wedivayisi yedijithali, kungaba usizo ukufunda kabanzi ngengozi yokuba ne-Computer Vision Syndrome. Nansi eminye imibuzo ongayibuza udokotela wakho:

• Ingabe ngisengozini yokuthola `(i-Computer Vision Syndrome)`?
• Yiziphi izimpawu okufanele ngiziqaphele?
• Yini engingayenza ukuze nginciphise izinkinga zamehlo ezibangelwa ukusebenzisa amadivayisi edijithali?
• Ingabe ngidinga incwadi kadokotela yezibuko ezintsha noma ama-contact lens?
• Kufanele ngigqoke nini izibuko zami noma ama-contact lens?

Okokugcina, izinto okufanele uzikhumbule

Amakhompyutha namanye amadivayisi edijithali enza izimpilo zethu zibe lula. Kodwa angaba nzima emehlweni ethu, ikakhulukazi uma siwasebenzisa isikhathi eside. Ngakho-ke, khuluma nodokotela wamehlo ngokuthi ungazuza kanjani ngesikhathi sokubuka isikrini ngaphandle kokubeka engcupheni induduzo yamehlo akho.

Okubaluleke kakhulu: Uma ubona izikhangiso zemikhiqizo ethi yehlisa "Ukucindezeleka Kwamehlo Edijithali," qiniseka ukuthi ukhuluma nodokotela ngaphambi kokuchitha imali kuzo. Kuwukuhlakanipha ukutshala isikhathi sakho nemali yakho kumkhiqizo oye wafakazelwa ukuthi uyasebenza ngocwaningo.

Nakekela amehlo akho!
