简要介绍了STYCAR分级球视力测试的起源和临床应用，以及对400多名正常婴儿和2岁半以下儿童以及850名12岁以下残疾儿童进行测试的临床结果。通过将球的大小与斯内伦字母的等效值相关联，可以表明12个月大的婴儿的正常视力至少为3/9 3/9（即相当于6/18 6/18），并且可能上级此。
The origin and clinical application of the STYCAR graded‐balls vision test are briefly described, together with clinical findings from tests applied to over 400 normal babies and children under the age of 2 1/2 years, and 850 handicapped children under 12 years of age. By relating ball sizes to Snellen letter equivalents, it has been possible to show that the normal visual acuity of 12‐month‐old infants is at least 3/9 3/9 (i.e. equivalent to 6/18 6/18), and is probably superior to this.
