Kwiimeko eziqhelekileyo, xa sijonga kude, izinto ezikude zifanekiselwa kwi-retina yamehlo ethu, ukuze sikwazi ukubona izinto ezikude ngokucacileyo;kodwa kumntu we-myopic, xa ejonga kude, umfanekiso wezinto ezikude uphambi kweretina, Ngumfanekiso ocacileyo kwi-fundus, ngoko akakwazi ukubona izinto ezikude ngokucacileyo.Izizathu ze-myopia, ukongeza kwizinto zokuzalwa zofuzo (bobabini abazali bane-myopic ephezulu) kunye nokungaqhelekanga ekuphuhliseni i-eyeballs ye-fetus, esona sizathu sibalulekileyo namhlanje yimpembelelo yendalo.

Ukuba umntwana akanayo i-myopia kunye neqondo le-astigmatism lingaphantsi kwama-75 degrees, ngokuqhelekileyo umbono womntwana ulungile;ukuba i-astigmatism inkulu okanye ilingana ne-100 degrees, nokuba umbono womntwana awunangxaki, abanye abantwana baya kubonisa iimpawu ezicacileyo zokudinwa okubonakalayo, njengentloko ebuhlungu, iingxaki zoxinaniso, njl. Ukungagxininisi, ukozela xa ufunda, njl. .
Emva kokugqoka iiglasi ze-astigmatism, nangona abanye abantwana bengaboni bengakhange baphucule kakhulu, iimpawu zokukhathala okubonakalayo zaye zakhululeka ngokukhawuleza.Ngoko ke, ukuba umntwana une-astigmatism enkulu okanye elingana nama-degrees angama-100, kungakhathaliseki ukuba umntwana ude kangakanani okanye ubona kude kangakanani, sincoma ukuba sihlale sinxibe iiglasi.
Ukuba iintsana kunye nabantwana abancinci bane-astigmatism ephezulu, ngokuqhelekileyo ibangelwa yi-eyeball dysplasia.Kufuneka zihlolwe kwangethuba kwaye zifumane iindondo kwangethuba, kungenjalo ziya kukhula ngokulula i-amblyopia.
