초록

Under night-time driving conditions, both cones and rods in eye’s retina simultaneously act to influence mesopic vision in two areas: central and peripheral visions. However, as people age, the amount of light received as well as the color temperature perceived by the human eyes also change. This research, through simulations and scaled down experiments with various headlight color temperatures and two levels of fixed brightness, deals with differences in ability to detect and identify obstacles by the subjects in their 20’s and 50’s.
According to the results obtained from the experiments on peripheral vision, subjects in their 20’s detected the obstacles more quickly at the combined color temperature of 3,000K+4,500K than at the single color temperature of 4,500K, and likewise at 3,000K+5,500K than at 5,500K; this tendency was significantly more noticeable for the subjects in their 50’s. As for the central vision, the results showed that there were no significant differences due to color temperature between the subjects in their 20’s and those in their 50’s. Moreover, the landolt ring experiment conducted under low luminance yielded higher percentage of correct answers at combined color temperatures.
