Objective:To investigate the rules of refractive changes in children with hypermetropia. 目的：探討兒童遠(yuǎn)視眼的屈光演變規(guī)律。
With age increasing, the diopter of these subjects had a tendency of hypermetropia from myopia. 隨著年齡的增長(zhǎng)，人眼的屈光度有由近視向遠(yuǎn)視變化的趨勢(shì)。
During development there was decrease in the degree of hypermetropia of increase in the degree of myopia (75% ) on the major spherical changes of all cases. 全部病例球鏡的主要變化為遠(yuǎn)視度數(shù)減少或近視度數(shù)增加（75％）。
