Paper Abstract:	Aging is rapidly progressing in Japan, and the number of patients of senile cataract is steadily increasing. Manner that the cataract people get a view is different from that of the normal that are not so, some consideration is considered necessary. Fraction of cataract people has reportedly been near 60% for ages of the 50’s and beyond 90% for the 80’s or higher, so it may be said that countermeasure against this sort of visual impairment is also one of extremely important subjects in order to raise life quality of the elderly. In these years, by the way, we have become visible of many LED-type articles for the train departure information within stations, the designation display of buses and the like. LED has been collecting eyes to merits of long lifetime and low power consumption, and its number of installation and range of application are considered to increase further. However, the present state of reported examples regarding the manner of viewing in chromatic vision of the elder, particularly for the LED display board, is extremely few. In this experiment, the authors attempted study and speculation with respect to the manner of viewing colors on the multicolored LED display board by means of goggle that fictionally reproduce visual environment of the cataract. It became evident from the result that perception of color has a large difference from yellowish green to aqua between visual environments of the cataract and normal, and further we qualitatively revealed its range and difference, too.
