Recent publicized reports based on the use of the Farnsworth Panel D-15 test suggest that a large percentage of young children have a deficiency of blue vision (tritan type). In our study, 413 school children (ages 3 to 10) were tested with both the Farnsworth Panel D-15 test, as well as the A.O. H-R-R plates. None of the children failed either test for blue-yellow vision when traditional scoring instructions were observed. As in previous reports, we find that the children make a number of minor errors which adults rarely make. These errors show marked age-related patterns, being more frequent in younger children. However, further analysis of these errors revealed that the relative frequency with which particular error types were made on the D-15 test was significantly correlated with the existing perceived color difference data for the visually normal adult population. In addition, retesting significantly reduced all error types and reversing the test sequence demonstrated that most of the minor errors were made in the last half of the test regardless of the color vision task. The overall increase in the number of minor test errors seen with young children seems unrelated to color defects. The modified scoring methods in conjunction with the characteristics of the Panel D-15 test design account for the high percentage of errors classified as errors of blue vision.
最近基于使用法恩斯沃思D - 15色盘测试所公布的报告表明，很大比例的幼儿存在蓝色视觉（蓝黄色型）缺陷。在我们的研究中，对413名3至10岁的学童进行了法恩斯沃思D - 15色盘测试以及A.O. H - R - R色盲检查图测试。当遵循传统评分说明时，没有一个孩子在蓝黄色视觉测试中不及格。与之前的报告一样，我们发现孩子们会犯一些成年人很少犯的小错误。这些错误呈现出明显的与年龄相关的模式，在年幼孩子中更为频繁。然而，对这些错误的进一步分析表明，在D - 15测试中特定错误类型出现的相对频率与视觉正常成年人群现有的感知颜色差异数据显著相关。此外，重新测试显著减少了所有错误类型，并且颠倒测试顺序表明，无论色觉任务如何，大多数小错误都出现在测试的后半部分。幼儿中观察到的小测试错误数量的总体增加似乎与颜色缺陷无关。修改后的评分方法结合D - 15色盘测试设计的特点，解释了被归类为蓝色视觉错误的高比例错误。
