For many years, anyone administering the Farnsworth 100 Hue Tests have complained about how patients cannot avoid touching the color discs. Further, the discs are very easy to lose, resulting with test kits becoming compromised.
The Panel 16 Color Vision Test includes 16 test caps and 17 restriction rings with one of the caps being a “pilot”. The diameter of the stimulus area is 1.3″ (3.3 cm), and can be reduced by using dark gray restriction rings with an opening of 0.47″ (1.2 cm) in diameter.Acrylic case includes a cloth storage pouch. Travel tube comes with black cloth. Comes with recording forms and instructions
The Lanthony Desaturated Color test is identical to the Farnsworth D-15, but the 15 disks are desaturated (lighter in hue). This allows the screener to determine whether or not the subject has the ability to discriminate between subtle color variations. The test can distinguish between normal color perception and mild deficiency in protan/deutan (red-green) or tritan (blue-yellow).
The lantern has been used since Dean Farnsworth first described it in 1946 for the testing the color signal discrimination ability of color anomalous individuals. This test has found longstanding application in the military and the transportation industry to qualify operators of ships vehicles and aircraft that are known to have failed screening tests such as the Ishihara plates.
