Common Reasons People Take EyeDetect Tests

You might find yourself scheduled for an EyeDetect test for any number of reasons. Understanding why you are being tested can help reduce anxiety and give context to the experience.

Pre-employment screening is the most common application. Law enforcement agencies, government contractors, and security companies increasingly use EyeDetect as part of their hiring process, either as a standalone screening tool or combined with a traditional polygraph [14]Verified Maryland Polygraph & EyeDetect Lie Detector Tests — Validate LLC

Regardless of your specific situation, the test process follows the same general sequence.

How to Book an EyeDetect Test

The booking process for an EyeDetect examination is similar to scheduling a polygraph test, though the pool of providers is growing rapidly. Not every polygraph examiner offers EyeDetect — the technology requires a Converus-certified EyeDetect station and training. You can search for certified providers through the Converus website or contact a professional examiner network that includes EyeDetect-equipped offices [17]Verified EyeDetect Can Now Be Used for Single Issue, Diagnostic Tests for Investigations
Confirms DLC test at 15 minutes and 90% accuracy, EyeDetect market release in 2014, DLC release in January 2019.

A reputable provider will conduct a brief consultation to understand the purpose of your test, identify the relevant issues, and determine which type of EyeDetect test format is appropriate for your situation. Most appointments are scheduled during normal business hours, though some providers offer evening or weekend availability.

EyeDetect tests typically cost between $300 and $800 depending on the provider, test type, and whether the test is court-ordered or for private purposes [18]Verified EyeDetect Now Accurately Scores Up to 4 Issues During a Lie Detector Test

How to Prepare for Your EyeDetect Test

Compared to a traditional polygraph, preparation for EyeDetect is minimal. There are no sensors to worry about, no breathing exercises to practice, and no need to avoid caffeine for hours before the test. However, several practical steps will help ensure the best possible testing conditions.

Get adequate sleep the night before — fatigue can affect pupil response and eye behavior. Aim for at least seven to eight hours of sleep. This is the single most important preparation step, similar to the advice in our guide on what to do the night before a lie detector test.

Avoid alcohol and recreational drugs for at least 24 hours before your test, as these substances can alter pupil response and affect test validity. Take prescription medications normally but inform the examiner of any medications you take, especially those known to affect pupil response such as certain psychiatric medications, antihistamines, or eye drops. Conditions like menopause or pregnancy should also be disclosed, though EyeDetect is generally less affected by physiological conditions than traditional polygraph.

Bring contact lenses if you normally wear glasses — you will need to remove glasses during the test because frames and lenses can create reflections that interfere with the infrared camera tracking [20]Verified Deception Detection — Red Sky Investigations
Confirms EyeDetect test fee of $300, 180,000+ measurements recorded per test, and 60 measurements per second per eye. Eat normally, arrive on time, and dress comfortably. Bring a valid photo ID, any relevant paperwork, payment if not already arranged, and a list of current medications.

What the Testing Environment Looks Like

EyeDetect testing takes place in a controlled environment designed to minimize distractions and ensure accurate eye-tracking data. The testing room is typically a quiet, private office or dedicated testing space that is climate-controlled and well-lit but not excessively bright. Ambient lighting conditions are important for accurate pupillometry measurements, so most testing rooms use diffused or indirect lighting rather than harsh fluorescent lights or direct sunlight.

At the center of the testing station, you will see a computer monitor, a desk or table, a comfortable chair, and an infrared camera mounted below the monitor [20]Verified Deception Detection — Red Sky Investigations
Confirms EyeDetect test fee of $300, 180,000+ measurements recorded per test, and 60 measurements per second per eye. The EyeDetect station also includes a chin rest to help maintain consistent positioning during the test [20]Verified Deception Detection — Red Sky Investigations

Confirms EyeDetect 5.1 release in February 2026 with real-time monitoring capabilities for administrators. The system is portable enough to be carried in a bag to regional or remote offices.

You will also see a mouse or wireless trackpad that you will use to provide your true/false responses. There are no wires to attach to your body, no blood pressure cuffs, no respiratory bands, and no finger plates. The entire test interaction happens between you, the screen, the camera, and the mouse. This is one of the key advantages over traditional portable polygraph systems that require multiple sensor attachments.

Meeting the Test Administrator

In many EyeDetect sessions, you will interact with a test administrator (proctor) rather than a traditional polygraph examiner. While many providers are licensed polygraph examiners who also offer EyeDetect, the test can be administered by a trained proctor because the scoring is fully automated — it does not require the subjective chart analysis that polygraph demands [3]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method

One proctor can manage up to three EyeDetect stations simultaneously, allowing organizations to process up to 40 tests in an eight-hour workday [2]Verified FAQs for EyeDetect
Confirms test formats (RCT, MCT, DLC), accuracy figures by test type (88% screening, 90% diagnostic), training requirements, and successive hurdles calculation.

The Pre-Test Conversation

Before testing begins, the administrator conducts a pre-test briefing. This phase ensures you understand what is about to happen, reduces anxiety, and establishes the legal and ethical framework for the examination.

Before testing with EyeDetect, the examinee typically watches an audio-visual presentation covering the test topics and receives instructions about how the test will be carried out [23]Verified The Polygraph and Lie Detection (NAS Report)
Foundational 2003 report on polygraph testing scientific validity by the National Academy of Sciences. The administrator will explain how EyeDetect technology works in general terms, describe the specific type of test you will be taking (screening or diagnostic), review the topics that will be covered, explain the scoring system and possible outcomes, answer your questions, discuss any medical conditions or vision issues that might affect the test, and explain your rights including the right to decline.

Unlike a traditional polygraph pre-test interview, which can last 45 minutes to over an hour and involves extensive discussion of specific questions, the EyeDetect pre-test briefing is generally shorter — typically 10 to 20 minutes. This is because EyeDetect questions are standardized and presented on the screen rather than being asked verbally by an examiner in real time.

Informed Consent

Before the test can proceed, you will be asked to sign an informed consent form. This document typically includes acknowledgment that you are taking the test voluntarily (or an explanation of the circumstances requiring it), a description of the technology being used, an explanation of how your data will be collected, stored, and shared, information about who will receive the test results, acknowledgment that you understand the test is not 100% accurate, and your agreement to proceed.

Read the consent document carefully and ask the administrator to explain anything that is unclear. You have the right to decline the test, though declining may have consequences depending on your situation.

Eye-Tracker Calibration Process

Once the pre-test briefing is complete and you have signed the consent form, the administrator will position you in front of the testing station and begin calibration. This critical technical step ensures the eye-tracking camera can accurately capture your eye movements throughout the test.

You will be asked to sit at the correct distance from the screen (typically 50 to 70 centimeters) and place your chin on the chin rest for consistent positioning [20]Verified Deception Detection — Red Sky Investigations
Confirms EyeDetect test fee of $300, 180,000+ measurements recorded per test, and 60 measurements per second per eye. If you wear glasses, you will be asked to remove them since frames and lenses create reflections that interfere with the infrared tracking. Contact lenses are generally acceptable.

A series of dots or targets will appear at various positions on the screen. You will follow each dot with your eyes as it moves, allowing the system to map the geometry of your eye movements relative to the screen. After the initial calibration, the system runs a quick validation to confirm accuracy. If calibration is not precise enough, the administrator may reposition you or repeat the process. The entire calibration typically takes two to five minutes. In rare cases where the system cannot achieve adequate calibration due to certain eye conditions or unusual eye anatomy, the test may need to be rescheduled.

Practice Questions

After successful calibration, you will be given a short set of practice questions to familiarize yourself with the test format [2]Verified FAQs for EyeDetect
Confirms test formats (RCT, MCT, DLC), accuracy figures by test type (88% screening, 90% diagnostic), training requirements, and successive hurdles calculation. These practice questions are not scored and do not count toward your results. They allow you to get comfortable with reading statements on the screen and clicking true or false with the mouse.

This practice round is your opportunity to ask any final questions about the mechanics of the test. Once you confirm you understand the process and feel comfortable, the actual test begins.

How the Test Is Structured

The core EyeDetect examination is a structured sequence of statements displayed on the computer screen, one at a time. For each statement, you read it silently and then use the mouse to indicate whether the statement is true or false as it applies to you. The test is timed but not in a pressured way — you are given a set amount of time to read and respond to each statement. The timing is designed to capture natural reading behavior, and rushing or deliberately slowing down can be detected by the system.

EyeDetect uses three primary test formats [22]Verified EyeDetect+ Revolutionizes Polygraph Technology with Less-Invasive Data Collection Methods
Confirms EyeDetect+ at 89-91% accuracy, tests at 20-45 minutes, released in 2021 with pulse transit time technology:

Relevant Comparison Test (RCT) — This is the primary format for screening, covering two unrelated relevant issues.

What You See on the Screen

During the test, the screen displays one statement at a time in clear, readable text. A typical screen view includes the statement in the center of the screen (for example: "Have you ever stolen money from an employer?"), response options labeled True and False that you click with the mouse, and a progress indicator showing approximately where you are in the test.

The statements are written in clear, direct language designed to be unambiguous. Questions are repeated in a randomized order across multiple sessions within the test [22]Verified EyeDetect+ Revolutionizes Polygraph Technology with Less-Invasive Data Collection Methods
Confirms EyeDetect+ at 89-91% accuracy, tests at 20-45 minutes, released in 2021 with pulse transit time technology. During a 30-minute screening test, over 180,000 individual eye measurements are recorded by the system [29]Verified CNN Tech — The eyes expose our lies
Confirms EyeDetect launch in 2014, use in 34+ countries, accuracy rates nearing 90%, and FBI investigator endorsement.

Relevant Questions

These are the questions that directly address the issues being investigated. In a pre-employment screening for a law enforcement agency, relevant questions might address drug use, criminal history, financial integrity, or other disqualifying behaviors. In a specific-issue diagnostic test, relevant questions focus on that particular event. Examples include: "Have you used illegal drugs in the past 2 years?" or "Have you stolen money, products, or confidential information from your previous employer?"

EyeDetect tests are designed to probe two relevant issues in the RCT format, or up to four in the MCT format [22]Verified EyeDetect+ Revolutionizes Polygraph Technology with Less-Invasive Data Collection Methods
Confirms EyeDetect+ at 89-91% accuracy, tests at 20-45 minutes, released in 2021 with pulse transit time technology. Each relevant issue serves as a control for the other, which is a key design difference from traditional polygraph where probable-lie comparison questions are used.

Comparison and Directed Lie Questions

In the DLC test format used for single-issue diagnostic testing, directed lie comparison questions are included alongside relevant questions. These are statements about common transgressions that most people will readily admit to, and the examinee is instructed to answer them untruthfully on purpose. The purpose of directed lies is to establish a baseline measure of what deceptive eye behavior looks like for each individual examinee.

In the RCT screening format, the comparison structure is different — responses to one relevant issue are compared algorithmically against responses to a secondary relevant issue. This eliminates concerns about overlap between relevant and comparison questions that can arise in traditional polygraph testing.

Neutral and Filler Questions

The test also includes neutral questions that are not scored. These serve as buffer items between scored questions and help establish baseline reading behavior. They might include general statements unrelated to the investigation topic. The algorithm uses data from all question types to build a comprehensive picture of your reading and eye behavior patterns.

Physical Sensations and Comfort

One of the most significant advantages of EyeDetect over traditional polygraph is physical comfort. There is no blood pressure cuff inflating on your arm (one of the most uncomfortable components of polygraph testing [3]Verified 12th Peer-Reviewed Publication Further Validates Eye Behavior as an Accurate Deception Detection Method
Confirms 12 peer-reviewed publications validating ODT method, 86–88% accuracy, 60 measurements per second, and 600+ worldwide customers), no respiratory bands around your chest, and no finger electrodes. You simply sit in a chair, rest your chin on the support, and interact with the computer screen.

The chin rest may feel slightly unfamiliar at first but is designed for comfort during the test duration. The infrared camera operates silently and is not visible during the test — you will not see a red light or feel any sensation from it. Most test-takers report that the experience feels similar to taking an online quiz or completing a computerized assessment.

The key is to read naturally and answer honestly. The system is designed to detect the involuntary eye responses that occur when someone is being deceptive — responses that cannot be consciously controlled. Converus has studied countermeasures for three years and found that people who try different countermeasures actually appeared more guilty as they were more conscious, leading to different involuntary eye movements.

Common Concerns During Testing

Many test-takers worry about blinking too much, reading too slowly, or making a mistake with their mouse clicks. These are normal concerns, but the algorithm accounts for natural variation in behavior. An occasional mis-click or moment of confusion will not determine your outcome — the system analyzes patterns across hundreds of data points throughout the entire test.

If you experience a technical issue during the test such as the chin rest slipping or the screen becoming difficult to read, the administrator monitoring the session can pause or restart the test. EyeDetect 5.1, released in February 2026, added enhanced real-time monitoring capabilities that allow administrators to identify subject cooperation issues or technical data interruptions before a test is finalized. For an overview of what EyeDetect cannot do and its technical boundaries, see our guide on EyeDetect limitations.

Understanding Accuracy Figures

Converus reports that EyeDetect accurately classifies 88 out of every 100 people in screening tests and 90 out of every 100 in diagnostic tests. This means the technology inaccurately classifies 12 out of 100 people in screening tests and 10 out of 100 in diagnostic testing. Research published in the European Polygraph Journal by Kircher and Raskin in December 2016 reported a mean accuracy of 86% for the Relevant Comparison Test screening format [25]Verified What Do Polygraphers–Practitioners Expect from Science?
Demonstrates polygraph practitioners' preference for familiar techniques over new technologies like EyeDetect, providing context for technology adoption patterns, and a mean accuracy of 90% for the Directed Lie Comparison diagnostic format based on field data analyzed in December 2018.

The initial peer-reviewed study was published in 2012 in the Journal of Experimental Psychology: Applied, which documented the effectiveness of the ocular-motor deception test. A 2016 study in the International Journal of Applied Psychology confirmed 85% accuracy with both English and Spanish-speaking participants, demonstrating cross-cultural reliability.

What Your Score Means

A score of 50 or above means you have been classified as credible — indicating the algorithm did not detect significant indicators of deception in your eye behavior. A score below 50 means you have been classified as deceptive — indicating the algorithm detected patterns consistent with deceptive responses [9]Verified The effects of prior expectations and outcome knowledge on polygraph examiners' decisions
Confirms that prior expectations create statistically significant bias in scoring inconclusive polygraph charts, reinforcing the advantage of automated scoring.

It is important to understand that no credibility assessment technology is 100% accurate. A deceptive classification does not necessarily mean you were lying, and a credible classification does not guarantee truthfulness. The score represents a statistical probability based on the analysis of multiple eye behavior variables. If you believe your results are inaccurate, discuss your options with the requesting party — some situations may allow for retesting or supplementary assessment with a different method.

This concept, originally proposed by Meehl and Rosen in 1955, holds that if a person passes two independent tests on the same topic, confidence in the result is substantially higher [5]Verified History of Converus

Converus reports that when EyeDetect and polygraph are used in combination and both tests agree, the outcome confidence reaches approximately 97 to 99% [5]Verified History of Converus
Confirms founding as CAT LLC in October 2009, renamed Converus December 12, 2013, science team formation in 2003, and EyeDetect market release in April 2014. The mathematical basis uses Bayes Theorem: if the probability of a false negative error is 17% for EyeDetect and 20% for polygraph, the joint probability that a deceptive person would pass both tests is 0.17 × 0.20 = 0.034 or 3.4% — yielding 96.6% accuracy. This successive hurdles model works because the two technologies measure largely independent physiological systems.

It is worth noting that this high combined confidence applies only when both tests agree. When the tests disagree, the results become inconclusive. Some providers like those in Maryland offer combination packages starting around $695 for both tests [19]Verified New Study Shows Accuracy of EyeDetect Remains Unchanged Between English and Spanish-Speaking Participants
Confirms cross-cultural accuracy of approximately 85% with no meaningful differences between language groups.

Medical Conditions and Medications

Certain medical conditions and medications can affect pupil response and potentially impact EyeDetect results. Always disclose to your test administrator any conditions affecting your eyes (such as glaucoma, cataracts, or recent eye surgery), medications that affect pupil dilation (including certain antidepressants, antihistamines, and eye drops), neurological conditions that may affect eye movement, and extreme fatigue or sleep deprivation.

The automated nature of EyeDetect means it is unaffected by the examinee's age, gender, language, or ethnicity according to Converus. Research has confirmed that accuracy remains consistent across English and Spanish-speaking populations.

Vision Requirements and Glasses

You must be able to read text on a computer screen to take a standard EyeDetect test. Contact lenses are preferred over glasses since eyeglass frames interfere with the infrared camera. If you cannot wear contacts and have a strong prescription, discuss this with your provider before the appointment.

For individuals who cannot read, Converus has developed audio-based test formats where questions are delivered orally through headphones. The EyeDetect+ system (the automated polygraph version) takes 20 to 45 minutes and can accommodate different testing needs.

Language Considerations

EyeDetect tests are available in more than 50 languages [11]Verified No More Hiding Those Lyin' Eyes with EyeDetect
Confirms EyeDetect use by 500+ customers in 40 countries, screening test at 30 minutes / 86% accuracy, diagnostic test at 15 minutes / 90% accuracy, 60 measurements per second. Examinees take the test in their native language for optimal results. The system's accuracy has been validated across language groups, with a peer-reviewed study confirming no meaningful differences between Mexican and U.S. participants on any behavioral or ocular-motor measure of deception.
