项目摘要

To clarify the differences in the perception of color between two groups with different iris colors, we measured color discrimination ability by the 100 hue test under an illuminance of 500 or 30 lx in Caucasian females with blue-green irises and Mongoloid females with brown irises, and obtained the following results. The total deviation score at 30 lx did not significantly differ between the blue-green iris and brown iris groups, but that at 500 lx was lower in the brown iris group, suggesting that color discrimination was easier at 500 lx in the brown iris group. In the blue-green iris group, hue discrimination was more difficult in the region from green (G) to purplish blue (PB) compared with the brown iris group under an illuminance of 500 lx, and the spectral luminous efficiency decreased in the blue (B) region in the light condition. In both groups, color discrimination in the red (R) region was low at 30 lx, showing significant differences between 30 lx and 500 lx. In the brown iris group, the discrimination ability in the blue (B) region was significantly lower at 30 lx than at 500 lx. Since color perception differed between the two groups with different iris colors, universal designs giving attention to differences in iris color are necessary.Concerning color discrimination ability according to the frequency of the use of sunglasses, in the brown iris group, the total deviation score was slightly higher in individuals not using sunglasses than in those sometimes or frequently using them under 500 as well as 30 lx. In the blue-green iris group, the total deviation score under 500 lx was significantly higher in individuals not using sunglasses than in those sometimes or frequently using them, showing a poorer color discrimination ability in individuals not using sunglasses. These results suggest the influences of UV in individuals in the blue-iris group not using sunglasses.

为了阐明不同虹膜颜色的两组之间在颜色感知上的差异，我们在500或30 lx的照度下通过100色调测试测量了具有蓝绿色虹膜的高加索女性和具有棕色虹膜的蒙古女性的颜色辨别能力，并获得了以下结果。蓝绿色虹膜组和棕色虹膜组在30 lx下的总偏差评分没有显著差异，但棕色虹膜组在500 lx下的总偏差评分较低，这表明棕色虹膜组在500 lx下更容易辨别颜色。在蓝-绿色虹膜组中，在500 lx的照度下，与棕色虹膜组相比，在从绿色（G）到紫蓝（PB）的区域中的色调辨别更困难，并且在光照条件下，在蓝色（B）区域中的光谱发光效率降低。在两组中，在30 lx时红色（R）区域的颜色辨别力较低，在30 lx和500 lx之间显示出显著差异。在棕色虹膜组中，在蓝色（B）区域的辨别能力在30 lx下显著低于在500 lx下。由于虹膜颜色不同的两组之间的颜色感知不同，因此需要考虑虹膜颜色差异的通用设计。关于根据太阳镜使用频率的颜色辨别能力，在棕色虹膜组中，不使用太阳镜的个体的总偏差得分略高于有时或经常使用太阳镜的个体，低于500和30 lx。在蓝绿色虹膜组中，在500勒克斯下的总偏差分数在不使用太阳镜的个体中显著高于那些有时或经常使用太阳镜的个体，表明不使用太阳镜的个体的颜色辨别能力较差。这些结果表明，紫外线的影响，在个人的蓝虹膜组不使用太阳镜。
