title: Predicting Farnsworth Lantern success with a six-plate series of the Ishihara pseudoisochromatic plates.
abstract: The Farnsworth Lantern (FALANT) is the definitive color vision test for the Navy, Marine Corps, and Coast Guard. It is also the definitive color vision test for aviation personnel in the Army. Results from it are also accepted by the Federal Aviation Administration. For various reasons, it is desirable to have an alternative test that can predict success (i.e., a passing score) on the FALANT. In 1991, it was shown that a 14-plate series of Ishihara pseudoisochromatic plates could predict FALANT success provided the proper passing criteria was chosen. Interest has arisen regarding whether or not a 6-plate series of Ishihara plates can predict FALANT success. A study was undertaken to answer this question. It appears that a 6-plate series of Ishihara pseudoisochromatic plates can predict FALANT success.
