For many years, anyone administering the Farnsworth D15, Lanthony Desaturated or 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 discs in the magnetic version are encapsulated in a sealed clear plastic box. The patient selects the discs using a magnetic pen to move them into a scoring area. When complete, scoring is easily accomplished by reading the scores through the bottom of the box. Tip the box and shake the discs into the selection area for the next patient!
Color testing becomes a game so that adults and children as young as 4 years old are much more engaged!
