AIM:To explore the effect of wearing glasses for myopia on exophoria and accommodation of children and adolescents. METHODS:They were divided into three groups of continued wearing glasses,no wearing and interrupted wearing glasses.Exophoria was measured with heterophorometer.The AC/A ratio was measured with a synoptophore. RESULTS:The mean near exophoria of continued wearing group had significant difference with that of no wearing and interrupted wearing groups.The mean distant exophoria of three groups had no significant difference.The average value of AC/A ratio in continued wearing group has significant difference with that of no wearing and interrupted wearing groups. CONCLUSION:Myopia of adolescents and children was prone to exophoria.Exophoria myopia with continued wearing of glasses can decrease AC/A ratio and exophoria.relieve asthenopia,and reduce myopia at certain level.
