What is EyeDetect Lie Detector?

The brain and eyes respond to deception. The greater the consequences of the lie, the greater the cognitive load. This affects the eyes. EyeDetect measures changes in pupil diameter, eye movement, reading behaviour, blinks, fixations and other things. Using an infrared camera and complex algorithm, a person’s credibility score is calculated: truthful or deceptive. Participants answer True/False questions on a computer. The infrared camera records eye behaviours. When the test concludes, responses to questions and eye measurements are uploaded to a web server for immediate scoring. Those authorized can view results in the web-based Converus Dashboard. A Converus Credibility Score shows the probability the person was truthful.

EyeDetect is a next-generation lie detector. It measures subtle changes in the eye to detect deception.

Renowned scientists at the University of Utah developed the technology in 2003 and have conducted research and made improvements ever since. The award-winning EyeDetect technology accurately tests job applicants, employees, patients, parolees, drug users, athletes, and criminal suspects about specific issues or crimes in just 15 to 30 minutes. EyeDetect can be used to administer screening tests on general topics. And, it can be used to administer diagnostic (single issue) tests for criminal or civil cases. It’s a true game changer in the lie detection industry.


  • 5 times faster than a polygraph test

  • Non bribable & no bias

  • Non invasive

  • Automatic fast results


The average polygraph lie detector test takes between 1 and 3 hours with the participant having cables and equipment stuck to them, being asked a series of questions from a human. The EyeDetect lie detector test administered by us takes on average 30 minutes making it the fastest most effective way to find out the truth.


No human can interfere with the test or results. The system can not be bribed or tricked into giving a pre discussed result making results accurate with no human interpretation. As polygraph tests are analysed by a human, there is room for bias and misinterpretation. With EyeDetect, there is zero room for error. The military grade encrypted system utilises complex analysis and equations, interrogating the smallest of detail to provide accurate results of integrity or deception.


A  polygraph lie detector test is a physiological recorder that assesses three indicators of autonomic arousal: heart rate/blood pressure, respiration, and skin conductivity. This requires the participant to have cables stuck to their skin which is uncomfortable, invasive and can raise stress levels during the examination. With EyeDetect, the participant of the lie detector simple reads from a computer screen and clicks two buttons for either true or false to the statements displayed. Two infrared cameras individually assess the reactions and movements of the eyes at a level no human could possibly observe, which provides details as to how the brain is functioning when being truthful or deceptive.


You could be waiting ages for polygraph results, with some people claiming to have waited weeks. The EyeDetect system is instant. Upon completion of the lie detector test, the encrypted data obtained is transferred to a cloud system which conducts the complex computer calculations and analysis, providing the easy to read and understand report within 5 minutes. You will know within 5 minutes, no need to spend hours, days or weeks wondering the results.


In any case, it is always better to know the truth. Deception, lies and false accusations can bring so much stress to our lives and in some cases, totally ruin someone's reputation, career or relationship. We can provide you the results you need in 30 minutes, at a location convenient to you with no invasive cables or monitors attached to the participant. They say the eyes are the gateway to the soul, that is why the revolutionary technology we employ is used by government agencies in immigration and integrity screening. There is no faster or more cost effective way to administer lie detector testing and the EyeDetect system is the most advanced deception detection method of our time. We utilise this advanced technology by bringing it into the private sector to assist all people from infidelity accusations to employee integrity screening for small and large businesses. From our home location in West Yorkshire, we provide affordable & fast lie detector testing to Leeds, Halifax, Bradford, Huddersfield & Wakefield. We are able to provide our service to all of Yorkshire and surrounding areas such as Harrogate, Manchester, Liverpool & Newcastle. We will come to you, simple and stress free.



Field studies show that EyeDetect has an accuracy range of 88 to 90%, depending on the test administered.


Incorruptible & Unbiased

Participants are tested by computer. The test administrator cannot alter test results. Test data is encrypted and tamper-proof.


Fast results

Tests take 15 to 30 minutes and reports are ready in less than 5. Reports include a credibility score and details showing participants’ responses to questions.


Flexible & Simple

We will travel to your home or office. The participant follows on screen instructions. A practice session helps to get comfortable with the test.
