| Research Abstract |
I have succeeded in building a database of the physiological properties of Japanese subjects on the distribution of the macular pigment density and the distribution of L/M cone ratio. First I built an apparatus that can measure the macular pigment density, and also one that can estimate L/M cone ratio by way of ERG flicker photometry. It turned out that the distribution of the macular pigment density of Japanese is similar to other races, but the L/M cone ratio of Japanese showed a significant different distribution from that of the American. This was a new finding through this research. Moreover, I have developed a simple and small apparatus that can measure color matching functions (CMFs), measuring the CMFs of the subjects whose physiological properties were measured with my apparatus.
