Operational Based Vision Assessment Cone Contrast Test: Description and Operation

  title={Operational Based Vision Assessment Cone Contrast Test: Description and Operation},
  author={James P. Gaska and Marc D. Winterbottom and Alex van Atta},
Abstract : The 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…

Automated Vision Test Development and Validation
This effort demonstrates that automated vision tests produce reliable results, with coefficients of determination for repeated testing above 0.80 for many of the tasks, and found that 100% sensitivity could be achieved using a fast screening method, however, at the cost of performing full threshold testing on over 30% of normal subjects.
Operational Based Vision Assessment Automated Vision Test Collection User Guide
This document describes the installation of the software, provides information concerning various menu options and operation of the test, and provides a brief description of each of the automated vision tests.
Colour vision standards: Past, present, and future
It becomes necessary to understand the role colour vision plays in the modern cockpit and suggest the colour vision standards accordingly, and understand the evolution of colour vision testing and colour theories, so as to develop or adopt a more suitable test for the changing aviation scenario.
Evaluation of the Cone Contrast Sensitivity Test in Normal Eyes and those with Congenital Color Blindness
The ColorDx Cone contrast test HD allows classification and quantitative evaluation of protans and deutans, and is thus useful when examining color vision status, and has 100% sensitivity and specificity in terms of diagnosing protan and deUTans respectively.


Rapid quantification of color vision: the cone contrast test.
The CCT provides a rapid (6 minutes), clinically expedient, measure of color vision for quantifying normal color performance, diagnosing type and severity of hereditary deficiency, and detection of acquired sensitivity loss due to ocular, neurologic, and/or systemic disease, as well as injury and physiological stressors, such as altitude and fatigue.
Color vision testing
This paper is a review of the current knowledge in the field of color vision testing and recommends a battery of tests for diagnosing the different categories of defects.

Cone-specific contrast sensitivity provides a quantitative measure of normal color vision and indicates both type and severity of color deficiency and is useful for diagnosing hereditary color deficiencyand for monitoring early color vision loss in ocular and systemic disease.

Fundamental chromaticity diagram with physiological axes
In 1931 CIE widened the scope of the photometric standard observer with the addition of colorimetric properties based on experimental studies by Wright and by Guild. Both of these studies were in
Detection mechanisms in L-, M-, and S-cone contrast space.
A red-green chromatic mechanism driven by delta L/L--delta M/M with no S-cone input that was 1 order of magnitude more sensitive than the two other mechanisms was revealed.
