First, to create a standard for testing DVA using all three testing protocols (head still, object moving; head moving, object still; head and object moving). Second, to examine reliability of the tests. Third, provide normative data.
Participants (n = 138) were males (n = 83) and females (n = 55) between the ages of 18-44 years old. All participants were tested on the RightEye Dynamic Visual Acuity Tests to determine reliability via Cronbach’s Alpha and Intraclass Correlation Coefficients (ICC). Age related differences were also examined across variables for two groups (under 30 and over 30) using t-test analysis.
All Cronbach’s Alphas were above an acceptable 0.7 level for reliability, ranging from .703-.953, thus demonstrating strong reliability across all tests. All ICC’s were statistically significant. There were no significant differences for age group on all DVA variables (p > .05). Normative data for each variable report means, standard deviations and ranges for participants aged 18-44 years.
Overall conclusions show that the RightEye Dynamic Visual Acuity tests show strong reliability and can therefore be used confidently as a measure of dynamic acuity. Data was collected with multiple testers and still showed excellent reliability. Future studies should examine non-healthy populations as well as young children and older adults.
