The primary purpose of this study was to collect data on the loss of color vision as a function of age. The Lanthony New Color Test (NCT), which measures acquired losses of color vision in the dimensions of hue, saturation, and brightness, was used to compile data on 68 subjects. The minimum number of subjects were 10 per decade from age 30 to 90 years. An age gradient of selective loss of discrimination of saturation beginning at age 50 was demonstrated, with rapid change noted after age 60. Similar findings were seen for hue but were not evident for brightness. By age 70, a neutral zone emerged at blue/purple, Munsell chroma level 2. The instrument was shown to be reliable and valid in comparison to the Farnsworth Dichotomous Panel D.15. It is seen that this information will provide a basis for planning safer, more functional environments for elderly people.
本研究的主要目的是收集色觉丧失随年龄变化的数据。使用兰托尼新色觉测试（NCT），该测试可测量在色调、饱和度和亮度维度上后天获得的色觉丧失情况，以收集68名受试者的数据。从30岁到90岁，每个十年的受试者最少为10名。结果表明，从50岁开始出现饱和度辨别选择性丧失的年龄梯度，60岁以后变化迅速。色调方面也有类似发现，但亮度方面不明显。到70岁时，在蓝色/紫色（孟塞尔彩度等级2）出现了一个中性区。与法恩斯沃思二分色盘D-15相比，该仪器被证明是可靠且有效的。可以看出，这些信息将为规划更安全、功能更完善的老年人环境提供依据。
