Ukukhathala kokubona kuyiqembu lezimpawu ezenza iso lomuntu libheke izinto ngaphezu kwalokho elingakwazi ukukuthwala ngenxa yezimbangela ezahlukahlukene, okuholela ekuphazamisekeni kokubona, ukungakhululeki kwamehlo noma izimpawu zomzimba ngemva kokusebenzisa amehlo..
Izifundo ze-epidemiological zibonise ukuthi u-23% wezingane ezifunda isikole, u-64% ~ 90% wabasebenzisi bekhompyutha kanye no-71.3% weziguli zamehlo omile babenezimpawu zokukhathala okuhlukahlukene kokubona.
Ngakho-ke ukukhathala kokubona kufanele kuncishiswe noma kuvinjelwe kanjani？
1. Ukudla okunomsoco
Izici zokudla ziyizici ezibalulekile zokulawula ezihlobene nokwanda kokukhathala kokubona. Isengezo sokudla esifanele sezakhamzimba ezifanele singavimbela futhi sibambezele ukwenzeka nokuthuthuka kokukhathala kokubona. Intsha ithanda ukudla ukudla okulula, iziphuzo kanye nokudla okusheshayo. Lolu hlobo lokudla lunenani eliphansi lokudla okunomsoco, kodwa lunamakhalori amaningi. Ukudla kwalokhu kudla kufanele kulawulwe. Yidla ukudla okuncane, upheke kakhulu bese udla ukudla okulinganiselayo.
2. Sebenzisa amaconsi amehlo ngokucophelela
Amaconsi amehlo ahlukene anezindlela zawo zokusebenzisa, njengokwelapha izifo zamehlo, ukunciphisa ingcindezi yangaphakathi kwamehlo, ukunciphisa ukuvuvukala nobuhlungu, noma ukuqeda amehlo omile. Njengeminye imithi, amaconsi amehlo amaningi anemiphumela emibi ethile. Ukusetshenziswa njalo kwamaconsi amehlo ngeke kubangele nje ukuncika emithini, kunciphise umsebenzi wokuzihlanza wamehlo, kodwa futhi kubangele umonakalo ku-cornea kanye ne-conjunctiva. Amaconsi amehlo aqukethe izithako zokulwa namagciwane angenza namagciwane emehlweni amelane nemithi. Uma kwenzeka ukutheleleka kwamehlo, akulula ukukwelapha.
3. Ukwabiwa kwamahora okusebenza ngendlela efanele
Izifundo zikhombisile ukuthi izikhawu ezivamile zingabuyisela uhlelo lokulawula iso. Ukulandela umthetho we-20-20-20 kudinga ikhefu lemizuzwana engu-20 esikrinini njalo ngemizuzu engu-20. Ngokwezikhathi ze-Optometry, udokotela wamehlo waseCalifornia uJeffrey Anshel waklama umthetho we-20-20-20 ukuze kube lula ukuphumula nokuvimbela ukukhathala kwamehlo. Okusho ukuthi, thatha ikhefu njalo ngemizuzu engu-20 usebenzisa ikhompyutha bese ubheka indawo (okungcono ibe luhlaza) eqhele ngamafidi angu-20 (cishe amamitha angu-6) okungenani imizuzwana engu-20.
4. Gqoka amalensi okuvimbela ukukhathala
Ilensi ye-Universe Optical anti-fatigue isebenzisa ukwakheka okungalingani, okungathuthukisa umsebenzi wokuhlanganisa umbono we-binocular, ukuze ibe nensimu yokubona ebanzi necacile uma ubheka eduze nakude. Ukusetshenziswa komsebenzi wokulungisa osizayo osetshenziswa eduze kunganciphisa ngempumelelo izimpawu zokoma kwamehlo kanye nekhanda elibuhlungu elibangelwa ukukhathala kokubona. Ngaphezu kwalokho, izinhlobo ezintathu ezahlukene zokukhanya okuphansi okungu-0.50, 0.75 kanye no-1.00 zenzelwe zonke izinhlobo zabantu ukuthi bazikhethe, okunganciphisa ngempumelelo ukukhathala kokubona okubangelwa ukusetshenziswa kwamehlo isikhathi eside futhi kuhlangane nazo zonke izinhlobo zezisebenzi eziseduze, njengabafundi, izisebenzi zasehhovisi, abadwebi nababhali.
Ilensi yokusiza ukukhathala kwe-Universe optical inesikhathi esifushane sokuzivumelanisa nezimo kuwo womabili amehlo. Ifaneleka kakhulu kwabaqalayo. Iyilensi esebenzayo etholakala kuwo wonke umuntu. Ingafakwa futhi ngemiklamo ekhethekile njengokumelana nokushayisana kanye nokumelana nokukhanya okuluhlaza okwesibhakabhaka ukuxazulula inkinga yokukhathala kokubona.
