Ukujongana nokujonga kwimeko yembono.
Ukujongana nokujonga, okanye i-myopia, yinkinga yamehlo eyenza izinto ekude zidibanise. Umntu osondeleyo unokubona ngokucacileyo izinto ezikufutshane nabo, kodwa kunzima ukugxila kwizinto ezikude.
Izimpawu kunye neMpawu
Omnye onokubona okungajongiyo angabonakala ngokubonakalayo xa ezama ukujonga izinto ezikude. Bangahlala kwakhona kufuphi nomabonwakude okanye bazise iincwadi ngokusondeleyo emehlweni abo xa befunda.
Ngamanye amaxesha ukujonga okubangela ukuba abantu bangabi nakwazi izinto ezikude.
Izizathu
Ukujongana nokujonga kwenzeka xa i-eyeball ibonisa ixesha elide kunexesha eliqhelekileyo, okanye xa i-cornea iphezulu kuneyona ndlela. Ezi meko zibangela ukukhanya kugxininise phambi kwe-retina endaweni ngqo kwi-surface. Kwiimeko ezininzi, ukujonga kwangaphambili kuzuze ilifa. Nangona kunjalo, kukho ubungqina obubonisa ukuba izinto ezinzulu zokuvala, ezifana nokufunda ixesha elide kwixesha elifutshane okanye ukudlala imidlalo yevidiyo ngeeyure ezininzi, ekukhuleni kwabantu abadala kunokubangela ukuba ukhangele phambili. Nangona, oogqirha bahlala bebona oku kwindlela yokwenza iiklinikhi, uphando luyahlukana ngoku njengesizathu sokubheka kwangaphambili. Kwamanye amazwe, uluntu lujonge kakhulu, ukuba lubonwa yingxaki yentsholongwane yoluntu okanye ubhubhane.
Ukuxilongwa
Ukuqhelaniswa kweso siqhelo kubonakala kubuntwaneni, phakathi kweminyaka eyi-10 no-20. Idla ngokufunyanwa xa umntwana ekhalaza ngokungakwazi ukufumana ibhodi.
Iimeko zihlala ziqhubeka ziba zimbi nakakhulu, kodwa zizinzileyo phakathi kwee-20. Ukugqithiswa kwezinto ezikufuphiyo kufumaneka ngolu vavanyo lwamehlo olunzulu olugqityiwe yi-optometrist okanye i-ophthalmologist. Uvavanyo lokutshatyalaliswa luya kwenziwa ngexesha loviwo oluqinisekisa ukuxilongwa kwe-myopia. Kwezinye iimeko ziza kwenziwa i- cycloplegic refraction .
Ukukhishwa kwe-cycloplegic kubalulekile kuba abantu abancinci bavame ukulinganisa kangangoko kunokuba bangaboni. Abanye abantu baphumelele ekujoliseni okanye bafumane i- spasm xa bevavanywa.
Unyango
Ngokuxhomekeke kwinqanaba lokujonga, abanye abantu banokufuna kuphela iilazi zokuqhuba okanye ukubukela ibhayisikobho. Abanye abanezinga eliphezulu lokujonga izinto ezinokuthi bangabonwa nje banokuba nombono ocacileyo ngamasentimitha ambalwa ukusuka ekhaleni labo. Ukujongana noBuchule kungaphathwa ngeiglasi, ii-lens zoqhagamshelwano okanye iinkqubo zelaser, ezifana neLASIK. Kwezinye iimeko, i-myopia nayo ingaphathwa nge-corneal-reshaping inkqubo, nangona iziphumo zihlala zisesigxina kwimvelo.
Isizathu sokukhathazeka
Ukujongwa kwangaphambili kunganciphisa umgangatho wobomi okanye kubangele i-eyestrain. Kwezinye iimeko, inokuphakamisa imiba yokhuseleko kwindawo yomsebenzi kwaye yandisa ingozi yezifo ezithile zamehlo, ezifana ne-glaucoma okanye i- retinal detachment . Umntu ojongene nomntu ophezulu, unomngcipheko wokuba neenkcenkceshela okanye i-detectment.
Ekuphumeni
Ngenxa yokuba ukujongwa kwantoni okanye i-myopia ephakamileyo e-United States nakwamanye amazwe amaninzi, abazali bahlala benomdla ezindleleni zokunciphisa umngcipheko wabantwana babo wokuba bajonge okanye bajonge ngakumbi.
Uphando olutshanje lukaJustin C. Shermin ngo-2011 lubonisa ukuba ngeyure nganye eyongezelelweyo abantwana bachitha ngaphandle ngaphandle kweveki, ingozi yabo yokuphuhlisa iyancipha ngamaphesenti amabini. Ukongezelela, umntwana osondeleyo kwenye yezifundo, uchithe umyinge wama-4 iiyure ezimbalwa ngeveki ngaphandle kwezingane eziqhelekileyo okanye abantwana abajonga phambili. Olunye ulwalamano olunomdla luye lwahlolwa kwakhona. Uhlolisiso lwazama ukufumana ukuba abantwana abachitha ixesha elingaphezulu ngaphandle kwe-aslo bachitha ixesha elingaphantsi bedlala imidlalo yekhomputha, becala ngokufunda okanye ukufunda. Nangona kunjalo, akukho buhlobo oluthe lwafunyanwa
