HRR Color Test; Non-Laminated

*Please note that this test is Non-Laminated and can become damaged when in contact with any liquids/fluids.* 

Features:

• Combination of several important aspects to provide the most advanced color vision test available
• Congenital and acquired testing
• Identification of the types of defect
• Diagnosis of the extent of the defect as well as a quick positive classification of normals
• Employs a sophisticated test strategy that virtually eliminates the potential for memorization and malingering
• The figures used are independent of language and are suitable for both adults and children
• Includes 6 plates for Screening and 14 plates to diagnose color deficiency

The HRR Pseudoisochromatic Plate Test 4th Edition supports very efficient color deficiency screening. The first four plates are used to show the patient 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 subject 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).
