Table 1.
Demographics and visual characteristics of participants. Acuity values in bold type denote the tested eye. For the older and young adult groups, only the group characteristics are given. LogMAR acuity of 0.0 is equivalent to Snellen acuity of 20/20. AMD = age-related macular degeneration; M = male; F = female; PRL = preferred retinal locus.
