Ukubona kude

Ukubona kude kunzima ukufumana izinto ezikufutshane kunezinto ezikude.

Eli gama lihlala lisetyenziselwa ukuchaza isidingo sokufunda iiglasi njengoko usiya ukhula. Nangona kunjalo, ixesha elichanekileyo laloo meko yi-presbyopia. Nangona inxulumene, i-presbyopia kunye ne-hyperopia (ukubona kude) ziimeko ezahlukeneyo. Abantu abane-hyperopia baya kuphuhlisa i-presbyopia kunye nobudala.

Ukubona kude sisiphumo somfanekiso obonakalayo ojolise emva kwe-retina kunokuba ujonge ngqo kuyo. Ingabangelwa kukugcwala kwamehlo kwamehlo okanye amandla okugxila abe buthathaka kakhulu. Inokudibanisa zombini.

Ukubona kude kusoloko kubakho kwasekuzalweni. Nangona kunjalo, abantwana banelensi yamehlo eguquguqukayo, enceda ukuyilungisa le ngxaki. Njengokuguga kwenzeka, iiglasi okanye iilensi zonxibelelwano zinokufuneka ukulungisa umbono. Ukuba unamalungu osapho abona kude, kunokwenzeka ukuba ube kude.

Iimpawu zibandakanya:

• Amehlo akhathazayo
• Umbono omfiliba xa ujonge kufutshane
• Amehlo awelekileyo (strabismus) kwabanye abantwana
• Uhlobo lwamehlo
• Intloko ebuhlungu ngelixa ufunda

Ukubona kude okuphakathi kunokubangela iingxaki. Nangona kunjalo, unokufuna ukufunda iiglasi kwakamsinya kunabantu abangenayo le meko.

Ukuvavanywa kwamehlo ngokubanzi ukufumanisa ukubona kude kunokubandakanya ezi mvavanyo zilandelayo:

• Ukuvavanywa kwentshukumo yamehlo
• Uvavanyo lweGlaucoma
• Uvavanyo lokurhoxisa
• Uviwo lwe-retinal
• Uviwo lwesibane
• Ubunzima bokubonakalayo
• Ukutsalwa kwe-cycloplegic -uvavanyo lokuphinda lwenziwe ngamehlo

Olu luhlu alubandakanyi konke.

Ukubona kude kuyalungiswa ngokulula ngeglasi okanye iilensi zonxibelelwano. Utyando luyafumaneka ukuze kulungiswe ukubona kude kubantu abadala. Olu khetho kubantu abanqwenela ukunxiba iiglasi okanye abafowunelwa.

Isiphumo kulindeleke ukuba sibe sihle.

Ukubona kude kunokuba ngumngcipheko we-glaucoma kunye namehlo aweleyo.

Tsalela umnxeba umboneleli wakho wezempilo okanye ugqirha wamehlo ukuba uneempawu zokubona kude kwaye khange ube novavanyo lwamehlo kutshanje.

Kwakhona, tsalela umnxeba ukuba umbono uqala ukuba mandundu emva kokuba ufunyaniswe unokubona kude.

Jonga umboneleli kwangoko ukuba ucinga ukuba ubona kude kwaye ngequbuliso uhlakulele ezi mpawu zilandelayo:

• Intlungu ebukhali yamehlo
• Ukubomvu kwamehlo
• Ukwehla kombono

Hyperopia

• Uvavanyo lwe-acuity ebonakalayo
• Ngesiqhelo, ukubona kude, kunye nokubona kude
• Umbono oqhelekileyo
• Utyando lweliso lweLasik - uthotho
• Kukude
