Specifications and Product Details:
The Lanthony Desaturated Test is much more difficult and is used to separate mild deficiency from normal. Both of these tests provide basic color testing for color sensitive industrial and military applications.The Farnsworth 100 Hue Test examines hue discrimination ability often used in vocational and diagnostic applications. The test has proven to provide reliable results which can be applied to many occupational and psychological situations. The Farnsworth 100 Hue test remains the most comprehensive color vision test.The Roth 28 and Lanthony 40 Hue tests provide some greater sensitivity levels than the 15 hue tests and are most often specified by clinical evaluations. The Sahlgren's test also provides greater sensitivity due to its design.The Farnsworth D15 and Lanthony D15 Tests from Richmond Products come in Plexiglas boxes which permit the patient to select the sequence of chips. Then the box is closed and the selections can be read thru the bottom for easy scoring. Because the box is closed, the score is preserved. The older wooden boxes required that the scoring be determined with the box flipped when open which left it vulnerable to spills.Both the Farnsworth and the Lanthony D15 tests include:15 color discs, a laminated score sheet, an instruction manual and 10 non-latex, lightly powdered gloves to prevent direct contact with the color discs.
