Ingabe nawe ubona konke kufiphele? Mhlawumbe lokhu kuyi-astigmatism!

Ingabe ngezinye izikhathi unenkinga yokubona izinto eziseduze noma ezikude? Ingabe izinhlamvu zibonakala zifiphele noma ziphukile? Noma ingabe ulahlekelwa umbono wakho lapho ushayela ebusuku ngenxa yokukhanya okuvela ezibanini? Lokhu kungaba izimpawu zokuthi ungase ube nesifo esibizwa ngokuthi i-astigmatism. Ungakhathazeki, kuvamile kakhulu. Ake sixoxe ngakho ngokuningiliziwe.

Kuyini i-astigmatism? Kalula nje...

Kalula nje, i-astigmatism iwukuba iso lakho lingabi yindilinga njengebhola, kodwa liyindilinga njengebhola le-rugby, noma libe yi-oval njengengemuva kwesipuni. Odokotela babiza lokhu ngokuthi iphutha lokubona . Lesi yisimo esivamile kakhulu, esibonakalayo emehlweni. Kodwa-ke, singenza umbono wakho ungabonakali kahle.

Ngokuvamile, iso eliphilile liyindilinga ngokuphelele. Ngakho-ke, imisebe yokukhanya engena esweni igxile endaweni eyodwa, okungukuthi, ku-retina. Yilapho-ke sibona khona ngokucacile. Kodwa uma sine-astigmatism, ngoba ukuma kweso kuhlukile, imisebe yokukhanya engenayo ayigxili endaweni eyodwa, kodwa ezindaweni eziningana. Yingakho sibona izinto zingacacile.

I-astigmatism ikuthinta kanjani ukubona kwakho?

Cabanga ngalokhu: izingxenye ezingaphakathi kwamehlo ethu zisebenza njengeqembu elijikijelana nge-relay. Uma ukukhanya kungena esweni, kudlula kuzo ngayinye ngayinye bese ekugcineni kuthunyelwa ebuchosheni.

1. Ukukhanya kuqala kungena engxenyeni esobala yeso, i-cornea .

2. Ukusuka lapho, lokhu kukhanya kuyagxila, kudlule kulensi, bese kuwela ku -retina ngemuva kweso.

3. I-retina iguqula lokhu kukhanya kube yizimpawu zikagesi bese izithumela ebuchosheni nge -optic nerve .

4. Ubuchopho yibo obudala izithombe esizibona kulezi zimpawu.

Manje, uma une-astigmatism, ukukhanya okungena esweni lakho akugobile kahle, okusho ukuthi kugobile kakhulu noma cha ngendlela efanele. Khona-ke ukukhanya akukwazi ukugxila endaweni eyodwa ngqo ku-retina. Okwenzekayo ukuthi ingxenye kuphela yalokho okubukayo icacile, kanti okunye kugobile. Yingakho izinto zibukeka zigobile futhi ngezinye izikhathi sengathi zigobile . Lokhu kungathinta izinto eziseduze kanye nezinto ezikude.

Ingabe zikhona izinhlobo ze-astigmatism?

Yebo, kunezinhlobo ezimbili eziyinhloko ze-astigmatism:

1. I-Corneal astigmatism:Lolu uhlobo oluvame kakhulu. Luvela lapho isimo se-cornea, ingxenye engaphambili yeso, singasasebenzi kahle.

2. I-Lenticular astigmatism: Lokhu kwenzeka lapho ukuma kwelensi ngaphakathi kweso kuba okungajwayelekile. I-Lenticular astigmatism ivame ukwenzeka nge -cataracts .

Abanye abantu bangase babe nazo zombili izinhlobo ndawonye.

Ubani othola i-astigmatism?

I-Astigmatism yinto engenzeka kunoma ubani . Abanye abantu bazalwa benalesi simo. Kwabanye, sikhula kamuva ekuphileni, okungukuthi, njengoba sebekhulile. Singaba ngcono noma sibe sibi kakhulu ngokuhamba kwesikhathi.

Lokhu kuvame kakhulu. Cishe, umuntu oyedwa kwabathathu une-astigmatism. Ngakho lokhu akuyona into eyingqayizivele kuwe.

Ziyini izimpawu ze-Astigmatism?

Ukubona okufiphele kuyisibonakaliso esiyinhloko nesivame kakhulu. Kwenza kube nzima ukubona imininingwane ngokucacile njengezinhlamvu kumenyu ephambi kwakho, izinombolo ebhodini lebhasi, noma izinhlamvu ephepheni legama kude. Ezinye izimpawu zifaka:

• Ukukhanya noma ama-halo azungeze izibani uma uzibuka.
• Bheka ngokucacile lapho ubheka ngamehlo avulekile . Cabanga nje, abanye abantu bayabheka amehlo lapho bebuka i-TV noma bebuka into ekude, yileyo ndlela okuyiyo.

• Izinkinga ngemva kokuhlinzwa kwamehlo .

Uthola kanjani ukuthi une-astigmatism?

Udokotela wamehlo angakutshela ngokuqinisekile ukuthi unalesi simo ngokuhlolwa kwamehlo . Uzobheka amehlo akho kahle (kufaka phakathi nangaphakathi). Lokhu kungenziwa ngokusebenzisa izivivinyo eziningana:

• Ukuhlolwa kokubona kahle: Lokhu ukuhlolwa kokubona ukuthi ubona kahle kangakanani. Uma wake waya kudokotela wamehlo wacela ukuba afunde izinhlamvu noma izimpawu odongeni, lokhu ukuhlolwa abakwenzile.

• Ukuhlinzwa kwamehlo kwe-LASIK
• Ukuhlinzwa Kwamehlo Kwe-PRK (Photorefractive Keratectomy)

Lokhu kuhlinza kusebenzisa imisebe ye-laser ukulungisa amaphutha okubona. Udokotela wamehlo oqeqeshwe ngokukhethekile (udokotela wamehlo) wenza lokhu kuhlinza. Lokhu kuhlinza kushintsha isimo se-cornea ukuze ukukhanya kuwele ngqo ku-retina.

Kulabo abane -cataract kanye ne-astigmatism, ukuhlinzwa kwe-cataract kuyindlela engcono kakhulu.Ungazilapha zombili lezi zinto ngesikhathi esisodwa.

Lokhu kuhlinzwa kunciphisa i-astigmatism futhi kuthuthukise ukubona. Uma unesifiso sokuhlinzwa kokulungisa umbono, khuluma nodokotela wakho wamehlo ukuze uthole ulwazi olwengeziwe.

Yini okufanele ilindelwe umuntu one-astigmatism?

• Ingabe ngizodinga amalensi okulungisa?
• Ingabe izibuko noma ama-contact lens angcono emehlweni ami?
• Ingabe ngingumuntu ofanelekela ukuhlinzwa kokulungisa umbono?
• Kufanele ngihlolwe amehlo kangaki?

Okokugcina, izinto okufanele uzikhumbule (Umyalezo Wokuya Ekhaya)

Ngakho-ke, i-astigmatism iyisimo esivame kakhulu lapho iso lakho lingekho nxazonke ngokuphelele, okubangela ukubona okufiphele.
