I-Myopia, i-astigmatism kunye ne-hyperopia zizifo zamehlo eziqhelekileyo kubemi, ezahlukileyo phakathi kwazo kwaye zisenokwenzeka ngexesha elinye, kumntu ofanayo.

Ngelixa i-myopia ibonakaliswa bubunzima ekuboneni izinto zikude, i-hyperopia ibubunzima bokuzibona zikufutshane. Ukubekwa ibala kwenza izinto zibonakale zimfiliba kakhulu, zibangela iintloko kunye noxinzelelo lwamehlo.

1. Imyopiya

I-Myopia sisifo esifa kunye nobangela ubunzima ekuboneni izinto zikude, zibangela ukuba umntu angaboni kakuhle. Ngokubanzi, inqanaba le-myopia liyonyuka de lizinze kufutshane neminyaka engama-30, ngaphandle kokusebenzisa iiglasi okanye iilensi zonxibelelwano, ezilungisa umbono ophuthileyo kwaye zingaphilisi i-myopia.

Kwenziwe ntoni

I-Myopia iyanyangeka, kwiimeko ezininzi, ngotyando lwe-laser, olunokulungisa iqondo ngokupheleleyo, kodwa ejolise ekunciphiseni ukuxhomekeka kulungiso, nokuba ziiglasi okanye iilensi zonxibelelwano. Fumanisa yonke into malunga nesi sifo.

2. Hyperopia

Kwi-hyperopia, kukho ubunzima ekuboneni izinto ezikufutshane kwaye kwenzeka xa iliso lifutshane kunesiqhelo okanye xa i-cornea ingenamandla ngokwaneleyo, ibangela ukuba umfanekiso wento ethile uyenze emva kweretina.

IHypopopia ihlala ivela ekuzalweni, kodwa ayinakufunyanwa ebuntwaneni kwaye inokubangela ubunzima bokufunda. Ke ngoko, kubalulekile ukuba kuvavanywe umbono ngaphambi kokuba umntwana angene esikolweni. Jonga ukuba uyazi njani ukuba yi-hyperopia.

Kwenziwe ntoni

I-Hyperopia iyanyangeka xa kukho into etyando, kodwa olona nyango luqhelekileyo nolusebenzayo ziiglasi kunye neelensi zonxibelelwano ukusombulula ingxaki.

3. Ubume benkwenkwezi

I-Astigmatism yenza umbono wezinto ungacacanga, ubangele iintloko kunye noxinzelelo lwamehlo, ngakumbi xa inxulunyaniswa nezinye iingxaki zombono ezinje nge-myopia.

Ngokubanzi, i-astigmatism ivela ekuzalweni, ngenxa yesiphene se-corneal curvature, ejikelezileyo engeyiyo embhoxo, ibangela imitha yokukhanya ijolise kwiindawo ezininzi kwi-retina endaweni yokugxila kwindawo enye, yenza owona mfanekiso ubukhali. Jonga indlela yokuchonga i-astigmatism.

Kwenziwe ntoni
