This D-15 Color Test Set (Saturated and Desaturated) is the newest version of two popular color deficiency tests (Farnsworth/Saturated and Lanthony/Desaturated). Comes complete with contemporary storage cases. When the patient replaces the caps, the tube is turned over to reveal a transparent plastic bottom, allowing the numbers on the bottom to be in clear view to facilitate quick and accurate scoring.
The Farnsworth-Lanthony Combined D-15 Test is designed to correctly identify all (congenital and acquired) color deficiencies, no matter how slight. A score sheet is enclosed to represent the order of the patient's arrangement of the caps, with respect to their correct sequence around the color circle. This allows the clinician to compare the axis of color confusion(s).
The long-standing, very-familiar, Farnsworth-Lanthony Combined D-15 Test Hue each consists of a set of 16 different colored papers affixed on the top of numbered caps. Each cap has a 1.2 cm circular disk of colored paper. The Munsell color system is used. A reference cap for each set is marked. Also included are instructions, score sheet, a pair of cotton gloves, and "C" Daylight Glasses. These glasses have special filters which transform normal incandescent light to "Illuminant C" type illumination, the proper light setting for the administration of color tests.
