Ukubona kude

Ukubona kude kunesikhathi esinzima sokubona izinto eziseduze kunezinto ezikude.

Leli gama livame ukusetshenziselwa ukuchaza isidingo sokufunda izibuko njengoba ukhula. Kodwa-ke, igama elifanele laleso simo yi-presbyopia. Yize kuhlobene, i-presbyopia ne-hyperopia (ukubona kude) yizimo ezahlukahlukene. Abantu abane-hyperopia nabo bazokwakha i-presbyopia ngeminyaka.

Ukubona kude kungumphumela wesithombe esibukwayo esigxile ngemuva kwe-retina kunokuba siqonde ngqo kuso. Kungabangelwa ukuthi inhlamvu yeso incane kakhulu noma amandla okugxila abe buthakathaka kakhulu. Kungaba futhi inhlanganisela yakho kokubili.

Ukubona kude kude kuvame ukubakhona kusukela ekuzalweni. Kodwa-ke, izingane zinelensi yamehlo eguquguqukayo, esiza ukulungisa le nkinga. Njengoba ukuguga kwenzeka, izingilazi noma amalensi oxhumana nawo kungadingeka ukulungisa umbono. Uma unamalungu omndeni abona kude, nawe kungenzeka ukuthi ube kude.

Izimpawu zifaka:

• Amehlo abuhlungu
• Ukubona okufiphele uma ubheka izinto eziseduze
• Amehlo awele (strabismus) kwezinye izingane
• Uhlobo lwamehlo
• Ubuhlungu bekhanda ngenkathi kufundwa

Ukubona kude okuncane akumele kudale izinkinga. Kodwa-ke, ungadinga ukufunda izibuko ngokushesha kunabantu abangenaso lesi simo.

Ukuhlolwa kwamehlo okujwayelekile ukuthola ukuthi ukubona kude kungabandakanya izivivinyo ezilandelayo:

• Ukuhlolwa kokuhamba kwamehlo
• Ukuhlolwa kwe-glaucoma
• Ukuhlolwa kwe-Refraction
• Ukuhlolwa kwe-retinal
• Ukuhlolwa kwesibani
• Ubukhali obubukwayo
• Ukukhishwa kwe-cycloplegic - isivivinyo sokuphinda senziwe ngamehlo avuliwe

Lolu hlu aluhlanganisi konke.

Ukubona kude kulungiswa kalula ngezingilazi noma ngamalensi wokuxhumana. Ukuhlinzwa kuyatholakala ukuze kulungiswe ukubona kude kubantu abadala. Lokhu kuyindlela kulabo abangafuni ukugqoka izibuko noma oxhumana nabo.

Umphumela kulindeleke ukuthi ube muhle.

Ukubona kude kungaba yingozi engcupheni ye-glaucoma namehlo awele.

Shayela umhlinzeki wakho wezokunakekelwa kwempilo noma udokotela wamehlo uma unezimpawu zokubona kude futhi awukaze uhlolwe iso muva nje.

Futhi, shayela uma umbono uqala ukuba mubi ngemuva kokutholakala unokubona kude.

Bona umhlinzeki ngokushesha uma ucabanga ukuthi ubona kude futhi ngokuzumayo uthuthukisa lezi zimpawu ezilandelayo:

• Ubuhlungu obukhulu beso
• Ukubomvu kwamehlo
• Ukwehla kombono

I-Hyperopia

• Ukuhlolwa kwe-acuity ebonakalayo
• Okujwayelekile, ukubona eduze, nokubona kude
• Umbono ojwayelekile
• Ukuhlinzwa kweso kweLasik - uchungechunge
• Ukubona kude
