This study investigated the effects of changes in luminance on the oral reading speeds of 13 participants with age-related macular degeneration (AMD) and a control group of six age-matched persons with typical vision. For the AMD participants, self-reports of light preferences were also recorded. In the AMD group, reading rates depended on light levels and were considerably lower than those of the control group. Reading speeds differed substantially among the AMD participants and, to obtain a functional range of luminance levels for reading, a combination of objective measurements and self-reports were required.
