The effect of two lighting conditions on performance of the Farnsworth Lantern color vision test.
This paper compares the performance of color defective patients on the Farnsworth Lantern test in both unlit and lit room conditions. We examined 18 dichromats and 33 anomalous trichromats, as diagnosed by the Mark I Nagel Anomaloscope. No statistically significant differences were found between their performance in the two conditions.
