The Farnsworth D-15 Colour Arrangement Test is a practical and widely used clinical test for assessing colour vision deficiencies. The test consists of one reference cap and 15 coloured caps. The patient arranges the coloured caps in the order that appears most natural to them, with the resulting sequence and score pattern used to identify and assess the presence of a clinically significant colour vision deficiency.

Designed for efficient clinical use, the Farnsworth D-15 offers quick administration, straightforward scoring and reliable repeatability. It is suitable for colour vision assessment in optometry, ophthalmology, occupational health and other clinical settings.

Key Features:

• Includes 1 reference cap and 15 coloured caps.
• Helps identify clinically significant colour vision deficiencies.
• Quick and easy to administer and score.
• Reliable and repeatable for clinical assessment.
• Scoring sheets included.
• Best used under suitable natural or standardised daylight conditions.
• Recommended for use against a black background to help provide optimal viewing conditions.

For the most consistent results, testing should be carried out under appropriate daylight or controlled illumination. A dedicated daylight viewing cabinet, such as the Good-Lite True Daylight Illuminated Cabinet, can be used to provide controlled lighting conditions during colour vision testing.
