PIA/GATF is now making available the Hardy, Rand, and Rittler (HRR) Pseudosiochromatic Test as well as the Farnsworth-Munsell 100 Hue Test. These color-vision testing products aid in the identification of color-vision deficiency and color discrimination, respectively.

The HRR Pseudosiochromatic Test is a test for identifying color-vision deficiency and provides a comprehensive evaluation of color-vision deficiency; it can be administered quickly and does not allow for easy memorization. The test includes a series of 24 plates, a brush for tracing shapes, instructions for proper testing, and scoring details to determine the type of color vision deficiency (eg, red-green or yellow-blue). Price: $295.

The Farnsworth-Munsell Test is useful in measuring acute color-vision discrimination and classifying those with normal color vision into above-average, average, and poor hue discrimination. The test consists of four sets of colored chips that must be arranged in an orderly progression of hue. The test is scored by revealing the differences between the observer’s arrangement of the chips and the proper order; any variations will show the inability to discriminate specific hues. Price: $970.
