Ngokweqile, i-astigmatism ihlukaniswa kanje:

• buthakathaka;
• ukuveza isilinganiso;
• izinga eliphezulu.

Kunezinhlanganiso eziningana zezifo ezicatshangelwayo, ezenziwe ngokuhambisana nokuguquka kwamandla okuphikisa, ukugxeka kanye nokugxila kokugxila kuma-eye meridians ehlukile.

Izibonakaliso ze-astigmatism kubantu abadala zixhomeke kakhulu kunoma yikuphi ukucindezeleka kwesifo. Ngakho, nge-pathology ephikisiwe, umuntu akazizwa engathandeki, akakwazi ngisho nokuqagela ku-anomaly onayo.

Izinga eliphezulu, ngokuphambene nalokho, lihambisana nezimpawu ezithile:

Ngokuvame ukutholakala kokugula, inkanyezi ye-Siemens isetshenzisiwe - isibalo esiqhakazile sejamo elizungezile, noma imidwebo efanayo. Kodwa kulula ukuzimela ngokuzimela ukuba khona kwe-astigmatism ngenxa yokuhlolwa okulula:

1. Vala isandla sakho sobunxele ngesandla sakho bese ubheka isithombe.
2. Phinda okufanayo ngeso lesokudla.

Uma, ngenkathi ubuka isithombe, ezinye izintambo azibonakali zibe zimnyama, kodwa imfucu noma imfucu emnyama, okungukuthi, izifo eziphawulekayo zokuzikhumbuza futhi kufanelekile ukuxhumana ngokushesha ne-ophthalmologist. Zonke izibopho kule ndawo zinebude obufanayo kanye nombala, zitholakala ebangeni elilingana ukusuka komunye nomunye.

Indlela yokuhlukanisa i-astigmatism kusuka kwezinye izifo zamehlo kubantu ngezimpawu?

Abanye abantu badidanisa izifo ezichazwe ngokukhubazeka okubukeka kakhudlwana, ukuphutha imidwebo emitholampilo evelayo.

Kubalulekile ukukhumbula ukuthi ukukhanda ikhanda, ukukhala nge-astigmatism akuveli ngokushesha ngemva kokucindezeleka kwamehlo, isibonelo, ukusebenza kwikhompyutha noma ukufunda ukuphrinta okuncane, futhi kamuva isikhathi esithile (kusuka kumaminithi angu-60 kuya emahoreni amathathu). Ngaphezu kwalokho, lesi sifo asibonakaliswa yi-hypermia (reddening) yamangqamuzana omuncu, ukukhukhuma kwamajwabu amehlo, ukubonakala kwemibuthano emnyama ezungeze amehlo. Izimpawu ezinjalo zihambisana ne-conjunctivitis, i- glaucoma , i-cataracts noma i-retinopathy.

Isici esicacile se-astigmatism yisithonya salo esibi ekutheni sigxile kokubili ezintweni ezikude nakwezinto ezizungezile, ngokuphambene nommoya weqiniso kanye ne-hypermetropia. Ezimweni eziningi, ukucaca kwesithombe kungatholakala ngokugxila ephuzu elilodwa, kepha isithombe esisebunzini sombono sendawo siyabonakala.
