EyeDetect can be used to replace in some circumstances and/or can complement the polygraph. In reality, EyeDetect is the perfect add-on service for a polygraph company. Studies show that the polygraph can be very accurate for event-specific questioning (a specific line of questioning). However, studies also show that EyeDetect has shown a superior level of accuracy compared to polygraph when used for employee pre-screening and periodic evaluations.
