SUPPLEMENTARY NOTESCleared, 88PA, Case # 2016-3064, 20 Jun 2016. Report contains color. ABSTRACTThe work detailed in this report was conducted by the Operational Based Vision Assessment (OBVA) Laboratory, Aeromedical Research Department, Human Performance Branch, U.S. Air Force School of Aerospace Medicine, Wright-Patterson AFB, OH, with support from SpecPro Technical Services. The report describes the development and operation of an improved version of the Rabin cone contrast test (CCT) currently used by the Air Force for aircrew color vision screening. The new OBVA CCT is differentiated from the Rabin device primarily by hardware, test procedures, and analysis techniques. Like the Rabin CCT, the OBVA CCT uses colors that selectively stimulate the cone photoreceptors of the standard human observer. The OBVA CCT builds on the success of the Rabin CCT through the use of highly accurate color display calibration, use of Landolt C optotypes to simplify response entry, and adoption of adaptive threshold estimation procedures well described in the research literature. This report summarizes the color calibration procedure and operation of the OBVA CCT and presents preliminary data demonstrating the validity of the new test for identifying and classifying protanomalous and deuteranomalous (red/green) color deficient individuals. SUBJECT TERMSColor vision screening, color vision, vision testing, aircrew selection, U.S. Air Force color vision standards, cone contrast test, CCT
