The Color Test Daylight Illuminator with Easel is specifically designed to provide the proper light and viewing angle for testing with Pseudoisochromatic plates. The Daylight bulb gives off 6280 degree K light which closely matches the standards set by the International Commission of Illumination and had been approved by the U.S. Food and Drug Administration and the U.S. Defense Personnel Support Center for the armed forces.
Daylight illumination has been found to be very important for acquired color vision defects (such as Plaquenil screening) and critical occupational applications. Consistency of lighting from exam to exam is very important in detection of drug interactions. Further, the use of daylight has been found to be very beneficial in stereopsis, and visual acuity testing.
The easel is removable for installation of a Flat Tray in order to use the Illuminator with arrangement tests
