Gulden Ophthalmics now offers 2 new magnetic D-15 color blindness diagnostic kits. The test can help determine between congenital or acquired, moderate and strong defects in deutan, protan, or tritan color discrimination.
Elkins Park, PA-Gulden Ophthalmics offers two new compact magnetic D-15 color blindness diagnostic kits. The kits are comprised of numbered colored discs housed in a compact sealed plastic box that is only 16 x 4 inches, saving counter space in the examination room.
The tests are easy to administer as well as simple and easy to perform by patients. Patients simply use a magnetic stylus to arrange the discs in the correct color order as they perceive it, and the arrangement is evaluated. Patients with color perception deficiencies will have difficulties trying to arrange the colored discs and will usually make mistakes. Based on the patient’s arrangement, the test can help determine between congenital or acquired moderate, and strong defects in deutan, protan, or tritan color discrimination. Based on the mistakes the type of color blindness as well its severity can be calculated. The tests can be used for occupational evaluation and classification.
Encased in the plastic enclosure, the discs are kept clean (not subject to fingerprints as in unenclosed, unprotected test kits), and cannot be lost; a Velcro cover protects the discs from fading due to sunlight and ambient light. The kits include a magnetic stylus with leather pouch and score sheet.
