Iyo imiterere y'ijisho ryawe itemerera urumuri kwibanda neza kuri retina, abahanga b'amaso babyita ikosa ryoroshye.Cornea yawe na lens bikorana kugirango uhuze urumuri kuri retina yawe, igice cyoroshye cyijisho ryijisho, kugirango ubone neza.Niba ijisho ryawe, cornea cyangwa lens yawe bitameze neza, urumuri ruzagabanuka cyangwa ntirwibande kuri retina nkuko bisanzwe.
Niba ureba kure, ijisho ryawe ni rirerire kuva imbere kugeza inyuma, cyangwa cornea yawe iragoramye cyane cyangwa hari ibibazo bijyanye nimiterere ya lens.Umucyo uza mu jisho ryawe wibanda imbere ya retina aho kuwukoraho, bigatuma ibintu bya kure bisa neza.
Mugihe myopiya isanzwe ihagaze neza mugihe cyo gukura hakiri kare, ingeso abana ningimbi bashiraho mbere yicyo gihe birashobora kwangiriza kutareba kure.
