Lie Detector Eye Test Newcastle is a UK-based lie detector test specialist. We offer fast, accurate and affordable services. Our modern lie detector test combines polygraph and eye detection technology, known to be the best in the field. The Polygraph captures a person’s heart rate, blood pressure, skin conductance, breathing activity and other body movements. The Eye Detect Optical Scan measures changes in the cognitive load that have an involuntary influence on the eyes and reading behaviour. The results of our ‘double hurdle tests’ have a 97 to 99 per cent accuracy.
