For many years, anyone using the Farnsworth D15, L'Anthony desaturated test or Farnsworth 100 Hue has complained about how patients cannot avoid touching the color disks with the result that the test kits become unusable. Further, the disks are very easy to loose.
We have developed a new packaging for these products in order to solve these problems. We have magnetized the disks and encapsulated them in a sealed clear plastic box. The patient selects the disks using a magnetic pen and moves them thru the gate into a scoring rail area. When complete, scoring is easily accomplished by reading the scores thru the bottom of the box. Tip the box around and the disks return to the corral for the next patient!
