Ukungaboni nokungaboni kahle

Ubumpofu ukungaboni. Kungabhekisa nasekulahlekelweni kombono okungenakulungiswa ngezibuko noma ngamalensi oxhumana nawo.

• Ubumpumputhe obuncane busho ukuthi unombono onqunyelwe.
• Impumputhe ephelele isho ukuthi awukwazi ukubona lutho futhi awuboni ukukhanya. (Iningi labantu abasebenzisa igama elithi "ubumpumputhe" lisho ukungaboni ngokuphelele.)

Abantu abanombono omubi kakhulu kuno-20/200, noma banezibuko noma ama-contact lens, babhekwa njengezimpumputhe ngokusemthethweni ezifundazweni eziningi e-United States.

Ukulahleka kombono kubhekisa ekulahlekelweni kombono okuyingxenye noma okuphelele. Lokhu kulahleka kombono kungenzeka ngokuzumayo noma esikhathini esithile.

Ezinye izinhlobo zokulahleka kombono aziholeli ekuphuphuthekiseni ngokuphelele.

Ukulahleka kombono kunezimbangela eziningi. E-United States, izimbangela ezihamba phambili yilezi:

• Izingozi noma ukulimala ebusweni beso (ukusha kwamakhemikhali noma ukulimala kwezemidlalo)
• Isifo sikashukela
• I-Glaucoma
• Ukwehla kwamakhompiyutha

Uhlobo lokulahleka kombono ngokwengxenye lungahluka, ngokuya ngesizathu:

• Ngamehlo, ukubona kungaguqubala noma kufiphale, futhi ukukhanya okukhanyayo kungadala ukukhanya
• Ngesifo sikashukela, umbono ungafiphala, kube khona izithunzi noma izindawo ezingekho zombono, nobunzima bokubona ebusuku
• Nge-glaucoma, kungahle kube nombono womhubhe nezindawo ezingekho zombono
• Ngokuwohloka kwe-macular, umbono ohlangothini ujwayelekile, kepha umbono ophakathi ulahleka kancane

Ezinye izimbangela zokulahleka kombono zifaka:

• Imithambo yegazi evinjiwe
• Izinkinga zokuzalwa ngaphambi kwesikhathi (i-retrolental fibroplasia)
• Izinkinga zokuhlinzwa kwamehlo
• Iso elinobuvila
• I-optic neuritis
• Unhlangothi
• I-retinitis pigmentosa
• Izicubu, ezifana ne-retinoblastoma ne-optic glioma

Ukungaboni okuphelele (akukho ukukhanya okukhanyayo) kuvame ukubangelwa:

• Ukuhlukumezeka okukhulu noma ukulimala
• Qedela iqembu le-retinal
• I-glaucoma yokugcina
• Ukuphela kwesigaba sesifo sikashukela
• Ukutheleleka okukhulu kwamehlo kwangaphakathi (endophthalmitis)
• Ukuvalwa kwemithambo yegazi (unhlangothi esweni)

Uma unombono ophansi, ungaba nenkinga yokushayela, ukufunda, noma ukwenza imisebenzi emincane njengokuthunga noma ukwenza ubuciko. Ungenza izinguquko ekhaya lakho kanye nemikhuba yakho ekusiza ukuthi uhlale uphephile futhi uzimele. Izinsizakalo eziningi zizokunikeza ukuqeqeshwa nokwesekwa okudingayo ukuze uphile ngokuzimela, kufaka phakathi ukusetshenziswa kwezinsiza-kufundisa eziphansi.

Ukulahleka kombono ngokungazelelwe kuhlale kuyisimo esiphuthumayo, noma ngabe awulahlekelwanga ngokuphelele umbono. Akufanele ungakunaki ukulahleka kombono, ucabanga ukuthi kuzoba ngcono.

Xhumana nodokotela wezifo zamehlo noma uye egumbini lezimo eziphuthumayo ngokushesha. Izinhlobo eziningi zokulahleka kombono azinabuhlungu, futhi ukungabikho kobuhlungu akusinciphisi neze isidingo esiphuthumayo sokuthola usizo lwezokwelashwa. Izinhlobo eziningi zokulahleka kombono zikunikeza kuphela isikhathi esifushane sokuthi welashwe ngempumelelo.

Umhlinzeki wakho wokunakekelwa kwezempilo uzokuhlolela iso ngokuphelele. Ukwelashwa kuzoya ngesizathu sokulahleka kombono.

Ngokulahleka kombono wesikhathi eside, bona uchwepheshe ongaboni kahle, ongakusiza ufunde ukuzinakekela futhi uphile impilo ephelele.
