Development of a low luminance vision-related performance-based measure

Many individuals with vision impairment report difficulties with everyday activities performed under low luminance conditions. This research involved the development of a new comprehensive vision-related low luminance performance-based measure, the ‘Assessment of Low Luminance Vision-Related Activities (ALLVA)’. The ALLVA was shown to be a valid and reliable instrument. The ALLVA could be used to better understand and quantify difficulties in performing vision-related activities under low luminance conditions, and evaluate low luminance injury prevention programs, the effectiveness of eye therapies and the outcomes of low vision rehabilitation in people with vision impairment.
