Ngaba amehlo akho adiniwe kukujonga ikhompyutha okanye ifowuni? Masithethe nge-(Computer Vision Syndrome)!

Ngaba uchitha uninzi losuku lwakho phambi kwekhompyutha? Okanye usebenzisa ifowuni yakho? Ngaba amehlo akho aziva ediniwe kakhulu kwaye ebuhlungu ngelo xesha? Mhlawumbi nentloko yakho ibuhlungu. Ukuba unengxaki enjalo, le yinto ebaluleke kakhulu kuwe.

Yintoni iComputer Vision Syndrome?

Ngamafutshane, `(Computer Vision Syndrome)` ibhekisa kwiingxaki ezenzeka emehlweni nasemizimbeni yethu xa sijonga 'izixhobo zedijithali' ezifana neekhompyutha, iitablet, kunye nee-smartphones ixesha elide. Oku kukwabizwa ngokuba yi-`(Digital Eye Strain).` Cinga ngale ndlela, amehlo ethu afana neekhamera ezimbini. Xa senza into enye ngokuphindaphindiweyo, nawo aziva ediniwe, akunjalo? Yiyo loo nto kunjalo.

Usenokuba neempawu ezifana neentlungu zamehlo, ukurhawuzelelwa, amehlo anamanzi, ukubona okufipheleyo, ubunzima bokujonga ukukhanya, kunye nentloko ebuhlungu. Le ayisiyongxaki imbi kangako, kodwa inokuphazamisa kakhulu imisebenzi yemihla ngemihla. Ngamanye amaxesha, ezi mpawu zinokuba nzima kakhulu kangangokuba awukwazi nokusebenza.

Ixhaphake kangakanani le meko?

Enyanisweni, le `(Computer Vision Syndrome)` yingxaki abantu abaninzi abanayo kwihlabathi liphela ngoku. Uphando lubonisa ukuba abantu abangaphezu kwezigidi ezingama-60 ehlabathini banengxaki yesi sifo. Ingakumbi ngexesha lobhubhane weCovid, abantu abaninzi baye bathembela kwizixhobo zedijithali ukuze basebenze ekhaya, bafunde, kwaye bathethe nabahlobo. Ngenxa yoko, le meko inyuke nangakumbi. Ngokweengxelo ezithile, malunga ne-78% yabantu abadala baye bahlaselwa yi-`(Computer Vision Syndrome)` ngeli xesha.

Kwanabantwana abancinci bayawela kule nto. Ngokungafaniyo nangaphambili, ngoku basebenzisa iifowuni kunye neetablethi kwizinto ezifana neeklasi 'ze-intanethi', imidlalo, kunye nokubukela iikhathuni. Ke ngoko, le meko inyukile yaya kuthi ga kwi-50% - 60% phakathi kwabantwana.

Zithini iimpawu zoku?

Makhe sijonge ezona mpawu zixhaphakileyo ze-"Computer Vision Syndrome".

Ukungonwabi kwamehlo

• Ukungakhululeki kwamehlo: Le yinto efunyanwa ngabantu abaninzi. Ingabandakanya amehlo omileyo, ukukrazula, ukurhawuzelela, ukutshisa, okanye ukuziva ngathi kukho isanti esweni.
• Umbono ofipheleyo: Ngequbuliso, izinto azicaci, zize ziphinde zicace emva kwexesha elithile. Oku kunokwenzeka ingakumbi xa ujonge kufutshane uze ujonge kude, okanye xa ujonge phantsi ujonge kude uze ujonge kufutshane.

• Ubunzima bokugcina amehlo akho evulekile.
• Intloko ebuhlungu: Intloko ebuhlungu, ingakumbi ephuma ngasemva kwamehlo.

Intlungu kwezinye iindawo zomzimba ngaphandle kwamehlo

Amaxesha amaninzi, abantu abane-"Computer Vision Syndrome" bafumana iintlungu nakwezinye iindawo zomzimba. Isizathu soku kukuba sihlala phambi kwekhompyutha ngendlela engafanelekanga, okanye sicinezela intamo yethu ukuze sijonge "isikrini." Yiyo le nto:

• Intlungu yentamo
• Intlungu yamagxa
• Umqolo obuhlungu

Izinto ezinjalo zinokwenzeka.

Kutheni le nto `(Computer Vision Syndrome)` isenzeka?

Isizathu esiphambili kukuba sichitha iiyure sijonge 'kwizikrini' 'zezixhobo zedijithali'. Ezinye izifundo zibonisa ukuba nokuba ujonge 'kwisikrini' iiyure ezimbini ngexesha kunokubangela ezi mpawu. Okukhona uchitha ixesha elininzi ujonge 'kwisikrini', kokukhona unokuba neengxaki ezingaphezulu.

Akupheleli nje ekujongeni isikrini. Nokuba sijonga into ekufutshane nathi, njengencwadi, amehlo ethu aziva ediniwe ixesha elide. Kodwa xa sijonga isikrini, oku kudinwa kukhulu nangakumbi. Kukho izizathu ezahlukeneyo zoku:

• Ukutshintsha rhoqo i-'Focus': Ubusazi na ukuba oonobumba nemifanekiso kwi-'screen' yenziwe ngamachaphaza amancinci kakhulu abizwa ngokuba yi-'pixels'. Ngoko ke, amehlo ethu kufuneka atshintshe rhoqo i-'focus' apha naphaya ukuze abone ngokucacileyo. Xa siqhubeka sijikeleza amehlo ethu ngolu hlobo, amehlo ethu ayadinwa.
• Inqanaba elithi `Contrast` le`Screen`: Rhoqo, umahluko ocacileyo `(contrast)` phakathi kombhalo okwi`Screen` kunye `(background)` yawo uphantsi. Emva koko amehlo ethu kufuneka asebenze nzima ukuze aqonde umbhalo.
• Ukuncipha kokuqhwanyaza: Ngokomyinge, siqhwanyaza malunga ne-18 ukuya kwi-22 ngomzuzu. Oku kubaluleke kakhulu ukuba amehlo afumane ukufuma okufunekayo (ukuthambisa). Kodwa okumangalisayo kukuba, xa sijonga ikhompyutha okanye ifowuni, inani lokuqhwanyaza liyehla liye kuthi ga kwi-3-7 ngomzuzu! Ngamanye amaxesha asivali namehlo ethu ngokupheleleyo size siqhwanyaze. Xa singaqhwanyazi kakuhle, umphezulu wamehlo uqala ukoma.

Ngubani osengozini enkulu yokuphuhlisa oku?

Ukuba usebenzisa ikhompyutha okanye esinye isixhobo sedijithali ixesha elingaphezu kweeyure ezine ngosuku, usengozini enkulu yokuba ne-Computer Vision Syndrome.

Kwakhona, ukuba unayo nayiphi na kwezi meko, iimpawu zinokuba nzima ngakumbi:
