Ukubona okufiphele, ukuzwela ekukhanyeni, ubunzima bokuhlukanisa izinhlamvu ezifanayo nokukhathala emehlweni yizimpawu eziyinhloko ze-astigmatism. Enganeni, le nkinga yombono ingabonakala ekusebenzeni kwengane esikoleni noma emikhubeni, efana, ngokwesibonelo, ukuvala amehlo akho ukuze ubone okuthile okungcono ukude, isibonelo.

I-Astigmatism yinkinga yombono eyenzeka ngenxa yokuguquka kokugobeka kwe-cornea, okwenza ukuthi izithombe zakheke ngendlela engagxiliwe. Qonda ukuthi i-astigmatism iyini nokuthi ungayelapha kanjani.

Izimpawu eziyinhloko

Izimpawu ze-astigmatism zivela lapho i-cornea yelinye noma womabili amehlo enezinguquko ekugobekeni kwawo, kuveza amaphuzu amaningana okugxila ku-retina okwenza ukuba izinhlaka zento ebonwayo zifiphale. Ngakho-ke, izimpawu zokuqala ze-astigmatism zifaka:

• Ukubona okungaboni kahle, izinhlamvu ezifanayo ezididekile, njenge-H, M noma i-N;
• Ukukhathala okukhulu emehlweni ngesikhathi sokufunda;
• Ukudwengula lapho uzama ukubona kugxilwe;
• Uhlobo lwamehlo;
• Ukuzwela ngokweqile ekukhanyeni.

Ezinye izimpawu, njengenkambu esontekile yombono nekhanda, zingavela lapho umuntu ene-astigmatism ngezinga eliphakeme noma ehlotshaniswa nezinye izinkinga zombono, njenge-hyperopia noma i-myopia, ngokwesibonelo. Funda umehluko phakathi kwe-hyperopia, myopia ne-astigmatism.

Izimpawu zezinsana ze-astigmatism

Izimpawu ze-astigmatism yobuntwana kungenzeka kungabi lula ukuzibona ngoba ingane ayazi enye indlela yokubona ngakho-ke, kungenzeka ingazibiki izimpawu.

Kodwa-ke, ezinye izimpawu abazali okufanele baziqaphele yilezi:

• Ingane iletha izinto eduze kakhulu kobuso ukuze ibone kangcono;
• Ubeka ubuso bakhe eduze kakhulu nezincwadi nomagazini ukuze afunde;
• Vala amehlo akho ukuze ubone kangcono ukude;
• Kunzima ukugxila esikoleni namamaki aphansi.

Izingane ezibonisa lezi zimpawu kufanele ziyiswe kudokotela wamehlo ukuze zihlolwe iso futhi, uma kunesidingo, ziqale ukugqoka izibuko. Thola ukuthi ukuhlolwa kwamehlo kwenziwa kanjani.

Yini engadala i-astigmatism

I-Astigmatism yinkinga yombono oyifa elingatholwa ngesikhathi sokuzalwa, noma kunjalo, isikhathi esiningi, kuqinisekiswa kuphela ebuntwaneni noma ebusheni lapho umuntu ebika ukuthi akaboni kahle, futhi angaba nemiphumela emibi esikoleni, ngoba isibonelo.

Naphezu kokuba yisifo esizalwa nefa, i-astigmatism nayo ingavela ngenxa yokushaywa ngamehlo, izifo zamehlo, njenge-keratoconus, ngokwesibonelo, noma ngenxa yokuhlinzwa okungaphumelelanga kakhulu. I-Astigmatism imvamisa ayibangelwa ukusondela kakhulu kuthelevishini noma ukusebenzisa ikhompyutha amahora amaningi, isibonelo.

Yelashwa kanjani

Ukwelashwa kwe-astigmatism kunqunywa ngudokotela wezifo zamehlo futhi kwenziwa ngokusebenzisa izibuko noma amalensi okuxhumana akuvumela ukuthi uguqule umbono ngokuya ngezinga umuntu alinikezayo.

Kodwa-ke, ezimweni ezinzima kakhulu ze-astigmatism, ukuhlinzeka kunganconywa ukuze kuguqulwe i-cornea futhi ngaleyo ndlela kuthuthukiswe umbono. Ukuhlinzwa, noma kunjalo, kunconywa kuphela abantu abazinze iziqu zabo okungenani unyaka owodwa noma abaneminyaka engaphezu kwengu-18 ubudala. Funda kabanzi ngokuhlinzwa kwe-astigmatism.
