Ukudinwa kokubona liqela leempawu ezenza iliso lomntu lijonge izinto ngaphezu kokuba umsebenzi walo wokubona unokuthwala ngenxa yezizathu ezahlukeneyo, ezibangela ukukhubazeka kokubona, ukungonwabi kwamehlo okanye iimpawu zomzimba emva kokusebenzisa amehlo..
Izifundo ze-Epidemiological zibonise ukuba ama-23% abantwana abakwiminyaka yesikolo, ama-64% ukuya kuma-90% abasebenzisi bekhompyutha kunye nama-71.3% ezigulane zamehlo awomileyo zazineempawu zokudinwa okubonakalayo ngokwamanqanaba ahlukeneyo.
Ngoko ke ukudinwa kokubona kufanele kuncitshiswe okanye kuthintelwe njani？
1. Ukutya okunesondlo
Izinto zokutya zizinto ezibalulekileyo ezilawulayo ezinxulumene nokuvela kokudinwa kokubona. Izongezo zokutya ezifanelekileyo zezondlo ezifanelekileyo zinokuthintela kwaye zilibazise ukwenzeka kunye nokukhula kokudinwa kokubona. Abantu abatsha bathanda ukutya izimuncumuncu, iziselo kunye nokutya okukhawulezayo. Olu hlobo lokutya lunexabiso eliphantsi lesondlo, kodwa luneekhalori ezinkulu. Ukutya okutyayo kufuneka kulawulwe. Yitya ukutya okuncinci, upheke ngakumbi kwaye utye ukutya okunesondlo esifanelekileyo.
2. Sebenzisa amathontsi amehlo ngononophelo
Amaconsi ahlukeneyo amehlo aneendlela zawo zokuwasebenzisa, njengokunyanga usulelo lwamehlo, ukunciphisa uxinzelelo lwangaphakathi kweso, ukunciphisa ukudumba kunye nentlungu, okanye ukunciphisa amehlo omileyo. Njengamanye amayeza, amaconsi amaninzi amehlo aneziphumo ebezingalindelekanga. Ukusetyenziswa rhoqo kwamaconsi amehlo akuyi kubangela ukuxhomekeka kwiziyobisi kuphela, kunciphisa umsebenzi wokuzicoca kwamehlo, kodwa kunokubangela nomonakalo kwi-cornea kunye ne-conjunctiva. Amaconsi amehlo anezithako zokulwa neentsholongwane anokwenza iintsholongwane emehlweni zinganyangeki ngamayeza. Xa usulelo lwamehlo luvele, akulula ukulunyanga.
3. Ukwabiwa kweeyure zokusebenza ngokufanelekileyo
Izifundo zibonise ukuba ukuphumla rhoqo kunokubuyisela inkqubo yokulawula iliso. Ukulandela umthetho we-20-20-20 kufuna ikhefu lemizuzwana engama-20 ukusuka kwisikrini rhoqo ngemizuzu engama-20. Ngokwexesha le-optometry, ugqirha wamehlo waseCalifornia uJeffrey Anshel uyile umthetho we-20-20-20 ukuze kube lula ukuphumla nokuthintela ukudinwa kwamehlo. Oko kukuthi, thatha ikhefu rhoqo ngemizuzu engama-20 usebenzisa ikhompyutha kwaye ujonge indawo (engcono ukuba luhlaza) kwiinyawo ezingama-20 (malunga neemitha ezi-6) ubuncinane imizuzwana engama-20.
4. Nxiba iilensi zokuthintela ukudinwa
Ilensi ye-Universe Optical anti-fatigue isebenzisa uyilo olungafaniyo, olunokuphucula umsebenzi wokuhlanganisa umbono we-binocular, ukuze ibe nombono ocacileyo nobanzi xa ujonge kufutshane nakude. Ukusetyenziswa komsebenzi wokulungisa oncedisayo osetyenziswa kufutshane kunokunciphisa ngempumelelo iimpawu zokoma kwamehlo kunye nentloko ebuhlungu ebangelwa kukudinwa kokubona. Ukongeza, iintlobo ezintathu ezahlukeneyo zokukhanya okuphantsi kwe-0.50, 0.75 kunye ne-1.00 zenzelwe zonke iintlobo zabantu ukuba bazikhethe, nto leyo enokunciphisa ngempumelelo ukudinwa kokubona okubangelwa kukusetyenziswa kwamehlo ixesha elide kwaye idibane nazo zonke iintlobo zabasebenzi abasondeleyo, njengabafundi, abasebenzi abasebenza eofisini, abapeyinti kunye nababhali.
Ilensi yokunceda ukudinwa kwe-Universe optical inexesha elifutshane lokuziqhelanisa namehlo omabini. Ifanelekile ngokukodwa kwabaqalayo. Yilensi esebenzayo efumanekayo kuye wonke umntu. Ingongezwa kunye noyilo olukhethekileyo olufana nokuxhathisa impembelelo kunye nokuxhathisa ukukhanya okuluhlaza okwesibhakabhaka ukusombulula ingxaki yokudinwa kokubona.
