Ukubukeka okufishane kuthinta abantu abaningi, ngenkathi ukulungiswa badinga izibuko ezimakwe ngokuthi "minus". Kulephutha elibukwayo, isithombe sakhiwa ngaphambi kwe-retina yeso, hhayi njengoba kufanele kube kuyo.
Izimpawu zokungaboni kahle
Uphawu oluyinhloko lwe-myopia yimbono yezinto ezingacacile kude. Umncintiswano wabo uyancipha, futhi imininingwane encane ayibonakali.
I-Myopia ibizwa nangokuthi "myopia", okusho ngesiGreki ukuthi "ukugcoba iso," futhi lokhu kubangelwa ukuthi abantu abane-myopia bahlala bexosha, bezama ukubona izinto ezikude. Kulesi simo, izinto ezitholakala eduze zibhekwa kahle - ngokucacile futhi nazo zonke imininingwane.
Esinye isici se-myopia yinkinga ekuhumusheni umbono ukusuka entweni eseduze kuze kube kude nangemuva.
Iziguli zingase zithole lezi zimpawu ezingezona ezigunyazayo:
- izimpukane phambi kwamehlo ;
- ukuphindaphindiwe kwezinto;
- ukuzwela okukhanya (ukudlula);
- umbono ongalungile wombala wezinto.
Ukuthuthukiswa kwe-myopia (uma lesi sifo siphuthuma ngokushesha, futhi amandla e-lens akhuliswa okungenani umshayeli owodwa ngonyaka) ihambisana nezinwele nokukhathala okubonakalayo ngenxa yokungaqhubeki kombono kanye nokulimala okusheshayo kwezicubu. Kungabangela ukulahlekelwa okuphawulekayo kwombono nokulahlekelwa okuyingxenye noma okuphelele kokukwazi ukusebenza.
Izimbangela zokubheka eduze
Namuhla, odokotela bayaqiniseka ukuthi i-myopia inesimo somzimba, ngakho-ke ivame ukukhula ngesikhathi sokukhula, lapho izicubu zingapheli.
Ngokulingana, izici eziningana zingasiza ekuthuthukiseni i-myopia:
- ukubuthakathaka kwezicubu ze-scleral;
- izimo ezimbi kanye nomsebenzi omude wokubukwa (ukukhanya okwanele nokubuka amahora amade ezinto ezincane ebaleni eliseduze - ukubopha, ukuhlala ekhompyutheni, ukufaka ubuhlalu, ukufunda, njll);
- ukufeza;
- ukuphumuza kwe-lens muscle, eyamsiza ukuba agxile ezintweni ezinokude okuhlukile.
Odokotela abaningi basikisela ukuthi imbangela yangempela ye-myopia ukuphulwa kwezinqubo ze-metabolic, okuholela ekubuthakathakeni kwezicubu.
Kusukela kumbono wokuphila womzimba we-myopia kwenzeka ngenxa yesayizi ekhuphukile yengxenye ye-antero-posterior ye-eyeball.
Kanti futhi odokotela babheka ukubona okungabonakali kwamanga, okubangela esinye isifo.
Ukuxilongwa kokubona okuseduze
Ukuxilongwa ngokugcwele kwe-myopia kunokwenzeka kuphela ezimweni zokwelapha:
- Ukuhlola ubuciko obubukwayo: indlela yokubona izinto kude nakancane ngaphandle kwamalensi nezibuko.
- I-degree ye-myopia inqunywe - amandla okubheka iso.
- Ubude be-eyeball bubalwa.
- Ubukhulu be-cornea kumaphuzu ahlukene bubalwa yi-ultrasound.
- I-bottom bottom isohlolwa ukuhlola isimo sezitsha, i-retina kanye nesibindi se-optic.
Ukuhlolwa okufushane okubukwayo kuqhutshwa ehhovisi le-ophthalmologist - lena indlela ye-duochrome, lapho ipuleti ihlukaniswe khona ngombala zibe izingxenye ezimbili, futhi izinhlamvu zamasayizi ahlukene ziphawulwe kuso. Uma izinhlamvu ezisemuva obomvu zibukeka zibukhali, khona-ke singakwazi ukuthatha i-myopia.
Kungenzeka yini ukwelapha i-myopia?
I-Myopia ngezigaba zakuqala isaphathwa kahle ngezinyathelo zokuzivikela - ukuvivinya amehlo, ukuhambisana nesimiso sokusebenza nokuthatha imithi.
Ekuqaleni, ungayeka ukulahlekelwa umbono, kodwa ukugqoka izibuko nama-lens, okudingekayo kulezi zimo, kuthinte kabi nakancane. Iqiniso liwukuthi iso liyajwayele, futhi akazikhandli ukwenza umsebenzi wokuzibona ngokwakhe ngaphandle kwezibuko.
Kwezinye izimo, ukukhubazeka okubukwayo kungadinga ukwelashwa okuhlinzekwayo.
Impendulo yokugcina, kungakhathaliseki ukuthi kungenzeka yini ukuqeda i-myopia, ingatholakala kuphela ngokucabangela zonke izici ezenza lesi sifo sibe yilowo nalowo icala.
