HRR Color Test

Product Number: 15251

Purchase the HRR Color Test 4th Edition from Gulden.  The HRR (Hardy Rand and Rittler) Pseudoisochromatic Plates provides the most advanced color vision test. Used for congenital and acquired testing, defect testings, and positive classifications of normals.


The HRR Pseudoisochromatic Plates 4th Edition employ a sophisticated test strategy that virtually eliminates the potential for memorization and malingering. The figures used by the plates are independent of language and suitable for both adults and children. The HRR Pseudoisochromatic Plates has achieved worldwide acceptance with instructions for the test administrator available in 24 different languages. Extensive clinical trials employing almost 100 normals and 125 color defectives testify to HRR efficacy.

Supports the most efficient color deficiency screening. Six plates (screening series) present the most difficult yellow, blue, red, and green colors and separate Normals from Defectives. Subsequent 14 plates diagnose as to the extent (mild, medium or strong) and type of defect (protan, deutan, tritan).
