Gulden Introduces Two New Compact

Magnetic D-15 Color Blindness Diagnostic Tools

 

The  popular D-15 color vision deficiency tests are available in the compact, magnetic format: Farnsworth Dichotomous D-15; Lanthony Desaturated D-15

 Gulden’s New Compact, Magnetic D-15 Color Blindness Tests combine compact size, ease of use, and other features of two most commonly used D-15 tests for color blindness.

 

ELKINS PARK, PA – Gulden Ophthalmics has introduced two new compact magnetic D-15 color blindness diagnostic kits that offer significant advantages over previous D-15 test kits.       The kits are comprised of numbered colored discs housed in a compact sealed plastic box that is only 16” x 4”, thus saving valuable counter space in the examination room compared to other magnetic D-15 kits. 

            The tests are easy to administer and 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 then evaluated. Patients with color perception deficiencies (“color blindness”) will have difficulties trying to arrange the colored discs and will usually make mistakes. The evaluation of the patient’s arrangement differentiates normal color perception from congenital or acquired moderate and strong defects in deutan (green and green weak blindness), protan (red blindness) or tritan (blue-yellow blindness) 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, are not subject to fingerprints as in unenclosed, unprotected test kits, and cannot be lost; a convenient 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.

            The widely-used popular D-15 color blindness tests are available in this new, compact, magnetic format: the standard Farnsworth Dichotomous D-15 and the Lanthony Desaturated D-15 with desaturated color discs, which make the test more challenging
