| Summary: | 碩士 === 嶺東科技大學 === 視覺傳達設計研究所 === 96 === The physiology of senior citizens will degenerate as age increases. Therefore, their discriminative ability of color aesthesia will reduce and their daily life will be influenced by mistakes made as a result of their deteriorating ability in discrimination.
This study is to firstly realize and discuss some relative questions about the visional function of senile cataract patients and its impact on colors by literature review, before conducting experiments in quasi-experiment method. We adopted the Farnsworth-Munsell 100 Hue Test in these experiments. Prior to the surgery, we evaluated 38 senile cataract patients whose eyesight is lower than 0.4 (inclusive). Then, after one-month of convalescence, we carried out the same evaluation and compared with the data to those we got before the surgery.
The main results of this research are:
1. Through the first part of the experiment in this research, we found that the senile cataract patients all have the difficulty to discriminate the colors. Moreover, patients have various degrees in their ability to discriminate colors due to the severity of their illness. According to the data, (BG)、(R)、(G)、(B) are the four color zones in which discriminative errors occur most easily.
2. In this research, we know from the experiments: 1. The score losing condition of the color caps. 2. The difference of color losing between every color cap. According to the results, an easily-differentiated chart was made based on the score losing condition of the color caps. We hope that designers in the future can adjust their color-depth according to the color losing condition on this chart in order to make the principle of common-use design practicable.
