Abstract
The purpose of this study was to examine the relationships between the visibility of mobile phone displays and aging effects on subjects’ visual functions, based on measurements of vision, including near visual acuity and cataract cloudiness. In the relation between Character size, CC, and NVA, visibility was lower with smaller character size “S”. In the relation between Contrast, CC, and NVA, the organoleptic evaluations showed significant differences in contrast. The subjects’ attached a high value to the negative display mode, especially when the subject’s CC was more than 200. Such considerations are particularly important for elderly users who have marked deterioration of visual function.
