Laminated HRR Pseudoisochromatic Test, 4th Edition

The HRR employs a sophisticated test strategy that virtually eliminates the potential for memorization and malingering. The figures used by the HRR Pseudoisochromatic Plates are independent of language and suitable for both adults and children.

The special non-glare laminate is spectrometer-tested to preserve true color fidelity, ensuring visuals remain vibrant and accurate. It also resists fingerprints and protects the surface from wear and damage.

The HRR Pseudoisochromatic Plate Test 4th Edition supports very efficient color deficiency screening. The first four plates are used to show the subject of how the test works. The fourth plate in this demonstration series has no figure and serves to potentially uncover attempts to memorize this test. The next six plates (screening series) present the most difficult protan, deutan, and tritan (red, green, yellow, and blue) targets. Success with these plates defines the individual as having ‘Normal Color Vision’ and completes the test. The subsequent 14 plates are the diagnostic series and provide diagnostic as to the extent (mild, medium, or strong) and type of defect (protan, deutan, tritan).

Key Features:

• Laminated pages provide lasting protection
• Six plates for screening
• 14 plates to diagnose color deficiency
