Abstract

Age-related opacity of the lens can happen to anyone. Lens opacity leads to decreased visual function, and damages the quality of life (QOL). It has been reported that lens opacity leads to absorption of blue color with short wavelength. Therefore, we hypothesized that the relationship between decrease in visual function and QOL can be examined if we can measure a person's recognition of blue color. In this study, we develop a visual function evaluation system to measure the blue color differential threshold. This system is implemented on tablet devices and displays a black Japanese character on a blue background. The background color can be changed based on the HSV color system. We conducted a survey on 27 participants aged 23-78 years, using the visual function system to measure the differential threshold and the NEI-VFQ25 vision-related questionnaire as a QOL evaluation tool. Consequently, we found a significant difference in blue contrast sensitivity between young participants and elderly participants. However, there was no correlation between blue contact sensitivity and QOL. In summary, based on the results, we believe that this system can measure blue contrast sensitivity and can be used for evaluating visual function.
