The Iowa Color Vision App allows users to capture color vision testing data from several commonly used testing modalities including the 14 plate Ishihara pseudo-isochromatic plate test, the Farnsworth-Munsell D15 test, the Hardy-Rand-Rittler pseudoisochromatic plate test, and a custom Color Naming test. The App also supports a custom LED-based digital anomaloscope developed at the University of Iowa. All of these results are collated into a PDF report.
