Abstract	The CIE has recently published a method for assessing the Visibility Level (VL) of realistic visual stimuli (as defined by Commission Internationale de l'Eclairage, 1981). To implement the system, a visibility meter is required; the Blackwell Visual Task Evaluator, Model 3X was designed to be used with the CIE method. At the request of the Chairman of the CIE Technical Committee 3.1 on visual performance, our laboratory undertook an independent evaluation of the instrument. The findings are reported here. While there are several idiosyncratic features of the Visual Task Evaluator, many of these findings are applicable to other visibility meters.
