L’Anthony Desaturated D15 Colour Test

The Lanthony Desaturated Colour test is identical to the Farnsworth D-15, except the 15 pots are Desaturated (i.e. lighter in hue). This allows the screener to determine whether or not the subject has the ability to discriminate between subtle colour variations. The test can distinguish between normal colour perception and mild deficiency in protan/deutan (red-green) or tritan (blue-yellow).

Available in the clear plastic square tube or in the magnetic tray system as in the Farnsworth D15 sets.
