项目摘要

While elderly persons look at the daily environment through the yellowing lens of the eye, their failure to discriminate color distinctions increases gradually, and this sensory deterioration may become quite serious for their vision in their daily lives. The object of this study is to develop filters correcting age-related lenticular yellowing vision. This study was held as follows: 1) We selected 50 colors on and inside the borderline of a Blue-Purple chromatogram (wavelength 460-410 nm), after colorimetring 132 blue-red mixed colors from color charts and plotting them in an xy-chromaticity diagram. 2) We added them each two kinds of brightness (Br.100%, 50%) and took them out as filters with a computer connected to a scanner and a color printer. 3) After testing seven kinds of Blue-Yellow mixed color charts used in thesis 1998, covered with each 2) above, we obtained 3 B.P. filters with high brightness correcting age-related lenticular middle level yellow vision, in order to return to each orginal color chromatogram and set in original colors' position line in the xy-chromaticity diagram. 4) However these filters need more bright vision and more different kinds of color tests, we study with a camera because of its light control system, which simulates to human eyes. We analyzed 220 colors in the Concise Manual of Color Names by taking photos of original and with correcting age-related yellowing middle-level filters and comparing their original and returned color positions in the xy-chromaticity diagram. The results showed that all color-brightness ratios nearly returned to each original ratio and 64% at the correcting color-postions returned to each original chromatogram.

当老年人通过眼睛的变黄的透镜观看日常环境时，他们辨别颜色的能力逐渐增加，并且这种感觉退化对于他们日常生活中的视力可能变得相当严重。本研究的目的是开发过滤器纠正年龄相关的晶状体黄化视力。本研究的主要内容如下：1）对132种蓝-红混合色进行比色，在蓝-紫色谱（波长460-410 nm）的边界线上和边界线内选取50种颜色，绘制xy-色度图。2)我们将它们分别添加两种亮度（Br.100%，50%），并将它们作为过滤器与连接到扫描仪和彩色打印机的计算机一起取出。3)通过对1998年论文中使用的7种蓝黄混色图的测试，分别覆盖上述2），我们获得了3种具有高亮度校正与年龄相关的透镜状中间水平黄视觉的B. P.滤光片，以返回到各原始色谱，并设置在xy-色度图中原始颜色的位置线上。4)然而，这些过滤器需要更明亮的视觉和更多不同种类的颜色测试，我们用相机进行研究，因为它的光控制系统，模拟人眼。我们分析了220种颜色的简明手册的颜色名称的原始照片，并与年龄相关的泛黄的中间级过滤器，并比较其原始和返回的颜色在xy色度图的位置。结果表明，所有色谱图的色亮度比基本恢复到原始色亮度比，64%的校正色位恢复到原始色亮度比。
