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 bothadults and children.
The kit comes with 6 plates (screening series) that present the most difficult,yellow, blue, red, and green, colors and separate Normals from Defectives. Subsequently, there are 14 plates that diagnose the extent (mild, medium or strong) and type of defect (protan, deutan, tritan). Standard English Version includes: 24 Plates, brush, English instructions and score sheet (notshown).
