Yonke imihla, ngakumbi nangakumbi abaguli bafuna unyango emva kokuchitha iintsuku ezinde phambi kwezikrini zekhompyuter. Ezona mpawu zixhaphakileyo ziquka ukucaphuka okanye ukurhawuzelelwa kwamehlo, kunye nokuvakala komile okanye isanti kumphezulu weliso.
Ezi ziimpawu ezixelayo zesifo samehlo esomileyo, esichaphazela naphina I-5% ukuya kwi-50% yabemi behlabathi, kuxhomekeke kwiminyaka, isini, ubuhlanga kunye nezinye izinto. Le meko inokuvela kwizizathu ezininzi, kodwa indlela yokuphila idlala indima ebalulekileyo. Ukusetyenziswa kwesikrini - kunye nokusetyenziswa ngokugqithiseleyo - yenye yezinto eziphambili.
Siqhwanyaza kancinci xa sijonga iikhompyuter, iifowuni kunye neetafile, kwaye xa sisenza, zethu ukuqhwanyaza kudla ngokungagqibekanga, oku kuthetha ukuba iliso alivaleki ngokupheleleyo. Izikrini zikwangumthombo wokukhanya okuqikelelweyo, okuphakamisa ubushushu bomphezulu weliso kunye nokunyusa ukukhupha kweenyembezi.
KwiYunivesithi yaseSantiago de Compostela, eSpain, saqhuba isifundo yabafundi baseyunivesithi abafumene ukufundiswa okuxutyiweyo ngexesha lobhubhani we-COVID: 50% yeeklasi zabo babezibonele ngokwabo, kwaye ama-50% babekwi-intanethi. Ngokwedatha esiyiqokelele, ixesha elongeziweyo lesikrini lidityaniswe neempawu zamehlo ezomileyo ezinobunzima. Abo basebenzise izikrini ixesha elingakumbi ngaphandle kweklasi (ngaphezu kweeyure ze-8 ngosuku) babonise iimpawu ezibukhali.
Nangona ukunciphisa ixesha lesikrini akunakwenzeka kwimisebenzi ethile, sinokunciphisa ukucaphuka kunye neengxaki ngokulandela iingcebiso ezithile. Ukuwuqonda ngokusisiseko lo mbandela kunokusinceda sinyamekele amehlo ethu.
Iinyembezi kunye neenkophe
Umphezulu weliso lenziwe ngeenkophe, ifilimu yokukrazula (ulwelo lweliso), i-cornea kunye ne-conjunctiva. I impilo kwezi zicubu zinxulunyaniswa nokusebenza kweliso. Ukuba kukho nayiphi na into echaphazelekayo, kunokukhokelela ekucaphukeni kwiso.
Ifilimu yeenyembezi yenziwe ngamacandelo amabini. Uluhlu olusezantsi luqukethe iiprotheni kunye namanzi, kwaye phezulu iqukethe ioli. Umaleko wamanzi unoxanduva lokugcina iliso limanzi, ngelixa ioli iyayithintela ukuba iphume ngokukhawuleza. Iingxaki kulo naluphi na umaleko zinokubangela ukungalingani, zithintele ukuba zingasasazwa ngokulinganayo kwaye zikhokelela ekucaphukeni.
Iinkophe zizo ezigcina ifilimu yeenyembezi isasazwe ngokulinganayo, kunye nokubonelela ngokhuseleko. Ukuqhwanyaza kancinane kaninzi – into esiyenzayo xa sijonga isikrini – kuthintela lo maleko ekubeni usasazwe ngokufanelekileyo kumphezulu weliso.
Ngaba uphethwe sisifo samehlo esomileyo?
Okokuqala nokuphambili, akukho sizathu sokoyika: ukubandezeleka kweempawu ezithile zamehlo omileyo akuthethi ukuba unesifo samehlo esomileyo. Isikhokelo esipapashwe yi Tear Film & Ocular Surface Society ikwenza kucace gca ukuba, ukongeza kwiimpawu ezixeliweyo, izigulane kufuneka zibonise iimpawu zomonakalo kumphezulu weliso. Ingcali yezonyango iya kugqiba ukuba ngaba lo monakalo ukhona, kwaye ngawaphi amanyathelo ekufuneka athathwe.
Kukho, nangona kunjalo, iimpawu ezithile ekufuneka uzilumkele. Ezi ziquka imvakalelo yokoma, ukurhawuzelelwa, ukutshisa, ukucaphuka okanye ukunkcenkceshela amehlo. Abaphandi bafumanise ukuba olona phawu luqhelekileyo emva kokusetyenziswa kwesikrini okwandisiweyo ukucaphuka.
Indlela yokunciphisa ukucaphuka kunye nokuphepha isifo samehlo esomileyo
Ngokuthatha amanyathelo okhuseleko, sinokuqinisekisa ukuba izikrini zisebenza nathi, hayi ngokuchasene nathi.
- Ubude beskrini: Kuhlala kukuhle ukugcina izikrini zingaphantsi kwinqanaba lamehlo. Ngale ndlela iinkophe akunyanzelekanga ukuba zivuleke kakhulu, nto leyo ethetha ukuba umphezulu weliso ubonakala ixesha elide.
- Indawo yesikrini kunye nokukhanya: Kuya kufuneka ukuphephe ukukhanya okubonisa ngaphandle kwezikrini, nokuba kukwisibane okanye kwifestile ngasemva apho uhlala khona. Ukukhanya okugqithisileyo kusinyanzela ukuba sigxile kakhulu, kwaye ke ukuqhwanyaza kancinci. Oku kungasonjululwa ngokusebenzisa izihluzo ezibonisa ukubonakaliswa.
- Amaxesha okuphumla: Ukuphumla ngumhlobo osenyongweni wamehlo akho. Umgaqo oqhelekileyo wesithupha ngumgaqo we-20-20-20. Rhoqo ngemizuzu engama-20 yomsebenzi, jonga into emalunga neemitha ezingama-20 (malunga neemitha ezi-6), kangangemizuzwana engama-20. Oku kuye kwaba ibonakaliswe ukunciphisa iimpawu zokomisa kwamehlo, njengoko ukujonga kude kwiscreen kwakhona kuseka izinga lethu eliqhelekileyo lokuqhwanyaza.
- Iimeko zokusingqongileyo: Ukufuma okuphantsi, amaqondo obushushu aphezulu, imisinga yomoya esuka kwiifestile ezivulekileyo okanye izifudumezi-moya, umsi wecuba kunye nesiqhumiso somoya esigqithisileyo zonke zinokuba yingozi empilweni yamehlo.
- Ukumanzisa kwamehlo: Amathontsi emehlo anokuba lolona khetho lulungileyo ngeentsuku zokusebenza ezibukhali. Gwema izisombululo ze-saline, njengoko ukubunjwa kwazo akufani nefilimu yeenyembezi. Abanazo ii-oyile kunye neeproteni, kwaye zinokuwuphelisa lo maleko. Olona khetho lungcono luyi-dose enye yeenyembezi ezenziweyo, ezingenazo izigcini kwaye zingonakalisi iliso.
Ukuxhaphaka kwezikrini kuluntu lwethu kuthetha ukuba iimpawu zeso esomileyo zixhaphakile. Ukuba sijongana nalo mba ngokuthatha amanyathelo afanelekileyo, nangona kunjalo, akunyanzelekanga ukuba kuchaphazele umgangatho wobomi bethu.
