View Shopping Cart
HRR 4TH Edition Subsets provide
separate tests which are a subset of the complete
HRR 4th Edition. One subset permits
for testing of Red and Green congenital defects. The other subset version
allows testing for Acquired defects (Tritan) by providing the Blue and Yellow
HRR color plates.
This Blue/Yellow Subset is an
easy way to complement an Ishihara test (which tests for congenital color
vision deficiencies only) to insure you have capability to test for Acquired
defects as well.
Each Subset contains 2
demonstration plates to help patients understand the test procedure. Each is
spiral bound with an integral cover, instructions, page tabs and a laminated
score sheet. The sum of these two books has all the plates contained in the
full HRR Pseudoisochromatic Book.
