Abstract
A method for conducting a color discrimination vision test includes displaying a test object comprised of two separate fields wherein one field has a fixed color hue and the other field has a variable color hue. The test subject is instructed to select which field corresponds to a color hue wherein one of the fields is the correct selection. The person makes the selection and the selection is recorded. Subsequent test objects are then displayed that are comprised of the fixed color hue field and the variable color hue field wherein the variable color hue field is a color hue different from the color hue of the previous test object. The display of subsequent test objects is then repeated and the test subject selections are then recorded.
