Mumamiriro ezvinhu akajairika, patinotarisa kure, zvinhu zviri kure zvinofananidzirwa pane retina yemaziso edu, kuitira kuti tigone kuona zvinhu zviri kure zvakajeka;asi kumunhu ane myopic, paanotarisa kure, mufananidzo wezvinhu zviri kure uri pamberi pe retina, Icho chifananidzo chisina kujeka mu fundus, saka haakwanisi kuona zvinhu zviri kure zvakajeka.Zvinokonzera myopia, kuwedzera kune congenital genetic factor (vabereki vose vane myopic yakanyanya) uye kukanganisa mukukura kwemaziso e fetus, chikonzero chinonyanya kukosha nhasi ndiko kukanganisa kwezvakatipoteredza.

Kana mwana asina myopia uye dhigirii ye astigmatism iri pasi pe 75 degrees, kazhinji maonero emwana akanaka;kana astigmatism yakakura kudarika kana yakaenzana ne100 madhigirii, kunyange kana kuona kwemwana kusina dambudziko, vamwe vana vacharatidzawo zviratidzo zvakajeka zvekuneta kwekuona, zvakadai semusoro, matambudziko ekugadzirisa, nezvimwewo. .
Mushure mekupfeka magirazi e astigmatism, kunyange zvazvo maziso evamwe vana asina kuvandudza zvakanyanya, zviratidzo zvekuona kuneta zvakakurumidza kusunungurwa.Nokudaro, kana mwana ane astigmatism yakakura kudarika kana yakaenzana ne100 degrees, pasinei nokuti mwana anoona kure kana kuti ari kure sei, tinokurudzira kugara tichipfeka magirazi.
Kana vacheche nevana vaduku vane astigmatism yakakwirira, inowanzokonzerwa ne eyeball dysplasia.Vanofanirwa kutariswa nekukurumidza uye kuwana magirazi nenguva, zvikasadaro vanozogadzira amblyopia nyore.
