The development of visual acuity and stereopsis was studied in 321 boys and 340 girls aged between 5 and 10 years. Visual acuity was assessed by the E test and a modified version of the STYCAR test, stereo acuity by the Lang-Stereo test [17]. Both vision tests showed an increase in the median visual acuity between the ages of 5 and 10 years. The E test indicated an increase from 1.2 between 5 and 6 years to 1.5-1.7 between 7 and 10 years. The values obtained with the STYCAR test were 0.6-1.3 higher, depending on the test rating used. Visual acuity norms between 5 and 10 years are presented as empirical centile curves. No significant differences were observed in visual acuity between the left and right eyes, nor between the sexes. The right eye was found to be the leading eye in 54.8% of the boys and 54.5% of the girls (P less than 0.001). The Lang-Stereo test was passed by 87.9%-94.3% of all children, and there were no significant differences with respect to age and sex. Children who failed the test had a significantly lower visual acuity than those who passed it. In the former group a significant interocular difference in visual acuity was present (P less than 0.01).
对321名5至10岁的男孩和340名5至10岁的女孩的视力和立体视发育情况进行了研究。视力通过E视力表测试和改良版的STYCAR测试进行评估，立体视通过Lang立体视测试[17]进行评估。两项视力测试均显示5至10岁儿童的中位视力有所提高。E视力表测试表明，视力从5至6岁时的1.2提高到7至10岁时的1.5 - 1.7。根据所使用的测试评级，STYCAR测试得出的值要高0.6 - 1.3。5至10岁的视力标准以经验百分位数曲线表示。左右眼之间以及不同性别之间在视力上均未观察到显著差异。发现54.8%的男孩和54.5%的女孩右眼为主导眼（P小于0.001）。所有儿童中有87.9% - 94.3%通过了Lang立体视测试，在年龄和性别方面没有显著差异。未通过测试的儿童视力明显低于通过测试的儿童。在前一组中，两眼之间的视力存在显著差异（P小于0.01）。
