Farnsworth Dichotomous Testing Sets are designed to indicate color deficiency quickly and easily. The Farnsworth D15 test is used to separate medium and strong color defect vs normal. Comes with a very sturdy stylish wooden case and test sheet.
The Farnsworth Dichotomous 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).
