We at British Lie Detector Test are pleased to provide a range of advanced lie-detecting techniques throughout the United Kingdom. One of the innovative technologies we use is EyeDetect, a non-invasive lie-detecting technology created by Converus. EyeDetect offers a more subtle technique than conventional polygraph tests, which track physiological reactions such as heart rate, blood pressure, and skin conductivity. EyeDetect uses a more subtle approach to assessing involuntary eye movements, including pupil dilation and blink rate, therefore evaluating sincerity. The legal legitimacy of EyeDetect tests in the United Kingdom will be examined in this essay, together with their admissibility in court, ethical issues, and pragmatic uses.
