Abstract

The age-related accommodation loss of the human eye impairs aging people's life. A study was conducted to preliminarily investigate the dynamic accommodative characteristics of the eye for different age groups under various intensities and chromaticities of light. 4 younger (20-29 years of age), and 4 older (60-69 years of age) participants were recruited, and the accommodation of their eyes was recorded and analyzed dynamically via the modified Shin-Nippon SRW-5000 autorefractor. The laboratory experiment was designed to assess accommodation in a simulated condition where the participant needed to alternate from viewing outside to reading the dashboard with signals of different light intensities (2 levels: 100 and 20 cd/m2) and light chromaticities (2 levels: red vs. blue). The results of the study indicated that aging, light intensity, and light chromaticity all had an impact on the dynamic accommodative characteristics of the eye. The implications of the study are discussed.
