The American Gem Society will introduce the HRR fourth edition Pseudoisochromatic Test for color deficiency screening during the JCK Show ~ Las Vegas.

Developed at Columbia University by LeGrand Hardy, MD, Gertrude Rand, and M. Catherine Rittler, with the assistance of several color vision experts, the latest edition has improved diagnostic accuracy through the use of updated color vision genetic information and state-of-the-art printing methods, AGS said in a statement.
