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.

当老年人通过发黄的晶状体观察日常环境时，他们辨别颜色的能力逐渐丧失，这种感官退化对他们日常生活中的视力可能会造成相当严重的影响。本研究的目的是开发滤光片来矫正老年性晶状体黄化视力。本研究的步骤如下：1)在蓝-紫色谱图（波长460-410 nm）的边界上和边界内选择50种颜色，对色度图中的132种蓝-红混合色进行比色，绘制成色度图。2)我们分别增加了两种亮度（100%,50%），然后用连接扫描仪和彩色打印机的计算机将它们作为滤光片取出。3)在对论文1998中使用的7种蓝黄混合色图进行测试后，分别覆盖上述2)，得到3个高亮度B.P.滤光片，校正年龄相关的透镜状中层黄色视觉，以返回到每个原始色相图，并在xy色度图中设置原始颜色的位置线。4)但是这些滤光片需要更亮的视觉和更多不同的颜色测试，我们用相机进行研究，因为它的光控制系统是模拟人眼的。我们对《颜色名称简明手册》中的220种颜色进行了分析，方法是对原始颜色和与年龄相关的变黄中级滤镜进行校正，并比较它们在x色度图中的原始和返回颜色位置。结果表明，色度比基本恢复到原色度比，校正色度比恢复到原色度比的64%。
