The relationship of refractive error to green-red ratios among color normals was investigated by asking 27 subjects to match a standard yellow with a mixture of red and green primaries using a Nagel anomaloscope. Green-red ratios did not show any regular change with refractive error. Differences in refractive error, natural or induced, among color normal persons did not change the measurements of color vision with the Nagel anomaloscope.
通过让27名受试者使用内格尔色盲检查镜，用红色和绿色原色的混合物匹配标准黄色，研究了色觉正常者中屈光不正与红绿比例之间的关系。红绿比例并未随屈光不正呈现出任何规律变化。色觉正常者之间自然或诱发的屈光不正差异，并不会改变用内格尔色盲检查镜进行的色觉测量结果。
