Some couples ask whether eye-tracking technology can settle infidelity doubts, and this guide weighs EyeDetect against a traditional lie detector test for relationship testing.
Before booking an EyeDetect test to resolve infidelity concerns, understand the critical limitations of this technology for relationship-specific questions. This comprehensive guide compares EyeDetect against traditional polygraph testing for couples, covering accuracy, question format constraints, emotional considerations, and what professionals actually recommend.
TL;DR — The Short Version
- EyeDetect's true/false computer format cannot address the specific, nuanced questions that relationship issues demand — traditional polygraph remains the professional standard for infidelity investigations.
- A polygraph examiner crafts customised questions about specific people, dates, locations, and types of contact, with clear operational definitions agreed upon before testing begins.
- EyeDetect's automated process lacks the pre-test interview, examiner interaction, and post-test discussion that are clinically and emotionally valuable for couples working through trust issues.
- The APA's 2011 meta-analysis found specific-issue polygraph testing achieves an aggregated decision accuracy of 89%, with a confidence interval of 83% to 95% — making it highly effective for targeted infidelity questions.
- Therapists working with betrayal trauma overwhelmingly recommend polygraph over EyeDetect because the human element of the examination supports the therapeutic process.
- EyeDetect costs roughly $300 to $400 per test, while polygraph infidelity examinations typically range from $400 to $900 — a modest difference considering the polygraph's significant advantages in flexibility and depth.

Privacy and Data Considerations
How EyeDetect Handles Your Data
An important consideration for couples dealing with sensitive infidelity allegations is data privacy. EyeDetect's data is uploaded to a secure cloud server at the conclusion of the test, where it is analysed by proprietary algorithms [7]Verified EyeDetect: Best Lie Detector
Confirms current accuracy claims of 86-88%, University of Utah development since 2003, and test data encryption standards. This means a third party — Converus — is involved in processing the data, which includes the specific questions asked and the subject's responses alongside biometric eye data.
Converus states that test data is encrypted and tamper-proof, using security features comparable to banking-level encryption [8]Verified Tech Co. Says its Advanced Lie Detector Will Save U.S. Gov't $29B Annually
Confirms EyeDetect used by 1,000+ customers worldwide, 100+ US law enforcement agencies, 60+ countries, and 50,000+ State Department-facilitated tests. However, the cloud-based architecture means that intimate details about a couple's relationship are transmitted and stored on external servers, which some individuals may find concerning given the extremely personal nature of infidelity allegations.
By contrast, a traditional polygraph examination's data remains with the examiner and is subject to direct confidentiality agreements between the examiner and the client. As a general rule, polygraph test results are confidential, with exceptions occurring only when the examiner is a mandatory reporter involving child, sexual, or physical abuse.
It's also worth being cautious about who administers your test. Our guide on polygraph bait-and-switch practices covers how to ensure you get the professional you booked.
When EyeDetect Might Be Appropriate for Relationships
Situations Where EyeDetect Can Add Value
Despite its limitations for detailed infidelity investigations, EyeDetect may be appropriate in certain relationship contexts:
As a preliminary screening tool before a full polygraph — some providers use EyeDetect as a first step, with individuals flagged for further polygraph examination. When both tests indicate deception on the same issue, Converus claims there is a 99% probability of lying [9]Verified New Lie Detection Technology Can Make Military Bases Safer
Confirms EyeDetect adoption by Colombian Air Force, Jamaica Defence Force, and US law enforcement agencies.
For ongoing monitoring in trust-rebuilding programmes — where periodic, broad-spectrum checks complement less frequent detailed polygraph examinations.
When the subject has a medical condition that prevents polygraph testing — EyeDetect requires no blood pressure cuff or chest tubes, making it suitable for pregnant women or individuals with certain cardiac conditions.
When speed and accessibility are critical — EyeDetect can be administered quickly at a counselling centre without scheduling a specialist polygraph examiner [11]Verified Cheating Partner - Infidelity Lie Detector Tests
Confirms infidelity testing methodology, question formatting standards, and importance of experienced examiners for domestic issue testing.
However, for the initial, high-stakes investigation of specific infidelity allegations, professional polygraph testing remains the recommended approach.

How to Choose the Right Test for Your Situation
Making the Best Decision for Your Relationship
Choosing the right credibility assessment method for infidelity testing depends on your specific circumstances. Here is a practical decision framework:
Choose polygraph if: You need answers about specific allegations involving named individuals, specific dates, or particular types of contact. You want a trained professional to develop precise questions with your input. Both partners need the emotional support and professional guidance of an experienced examiner. The results will be used in a therapeutic context where nuanced interpretation matters. You need post-test conversation and potential disclosure facilitation.
Consider EyeDetect if: You want a quick, non-invasive preliminary screening before investing in a full polygraph. The questions are broad (e.g., general fidelity verification rather than specific-person allegations). The subject has medical conditions that make polygraph unsuitable. You plan to use it in combination with polygraph for maximum confidence.
For both options, always verify the credentials of the provider. Make sure your polygraph examiner graduated from an APA-approved school or an equivalent professional body, uses APA-validated techniques, and has specific experience with domestic issue testing [14]Verified Essentials of the Relevant Issue Gravity (RIG) Strength: A Theoretical Framework for Understanding the CQT

- No examiner interaction during EyeDetect means no emotional assessment, no question clarification, and no post-test discussion
- Most EyeDetect accuracy research focuses on screening applications rather than the emotionally charged scenarios typical of infidelity
- EyeDetect data is uploaded to Converus cloud servers, introducing a third party into the processing of intimate personal data
- Polygraph examinations take significantly longer (1.5 to 3 hours vs. 15-30 minutes) and cost more
- EyeDetect results may leave couples with more questions than answers, particularly if scores fall in an ambiguous range
Frequently Asked Questions
Can EyeDetect detect infidelity as accurately as a polygraph?
For infidelity-specific testing, polygraph is more suitable than EyeDetect. While EyeDetect reports 86-88% accuracy for screening tests, these figures are based on broad screening-type questions — not the highly specific, emotionally charged questions that infidelity cases require. The APA's meta-analysis found specific-issue polygraph testing achieves 89% accuracy with a confidence interval of 83% to 95%. More importantly, polygraph allows customised questions about specific people, dates, and behaviours that EyeDetect's true/false format cannot accommodate.
How much does an EyeDetect infidelity test cost compared to a polygraph?
EyeDetect tests for private individuals typically cost $300 to $400 per test. Professional polygraph infidelity examinations range from $400 to $900 for a single-issue test, with some specialists charging $500 to $1,500+ depending on complexity and location. The cost difference is relatively modest considering the polygraph's significant advantages in question customisation, examiner interaction, and emotional support. Some providers offer combined EyeDetect and polygraph packages for around $695.
Is EyeDetect admissible in court for infidelity cases?
EyeDetect has very limited legal admissibility. Polygraph results themselves have variable admissibility depending on jurisdiction — they are admitted by stipulation in some states and subject to judicial discretion in federal court. Neither technology's results are universally accepted as court evidence. For a comprehensive analysis, see our guide to EyeDetect admissibility in court.
Can I take both an EyeDetect and polygraph test for infidelity?
Yes, and some professionals recommend this approach. Using EyeDetect as a preliminary screening followed by polygraph for a more detailed investigation can provide maximum confidence. Some providers report that when both tests indicate deception on the same issue, the outcome confidence rate rises to 97% or higher. This successive-hurdles approach combines the speed of EyeDetect with the depth and specificity of polygraph.
How long does each test take?
An EyeDetect test takes 15 to 30 minutes, with results available within five minutes. A professional polygraph infidelity examination typically takes 1.5 to 3 hours, including the pre-test interview (30-60 minutes), the actual testing phase, and the post-test discussion. While significantly longer, the polygraph's extended format allows for thorough question development, emotional preparation, and result interpretation.
Do therapists recommend EyeDetect or polygraph for couples?
Therapists working with infidelity and betrayal trauma overwhelmingly prefer polygraph for couples. The pre-test interview, examiner interaction, and post-test discussion integrate naturally into therapeutic protocols. Some counselling centres have adopted EyeDetect as a quick screening tool, but for the detailed disclosure and trust-rebuilding process, the human element of a professional polygraph examination is considered essential by most practitioners.
Can someone cheat on an EyeDetect infidelity test?
EyeDetect measures involuntary eye behaviour that is difficult to consciously control — pupil dilation, blink rate, fixation patterns, and reading speed are autonomic responses. However, the National Academy of Sciences has noted that countermeasures pose a potentially serious threat to any physiological deception detection method. EyeDetect's automated format eliminates certain forms of examiner bias but also removes the human ability to detect unusual behaviour or countermeasure attempts.
What happens to my data after an EyeDetect test?
At the conclusion of an EyeDetect test, the eye measurements and test responses are uploaded to a secure cloud server operated by Converus, where they are analysed by proprietary algorithms. Converus states that test data is encrypted and tamper-proof. However, this means intimate details about relationship allegations are processed and stored on external servers, which some individuals may find concerning given the personal nature of infidelity testing.
Is EyeDetect better for people who are nervous about taking a polygraph?
EyeDetect may feel less intimidating because it requires no physical sensors, wires, or blood pressure cuffs. The subject simply sits in front of a computer and responds to true/false questions. However, for anxious individuals, the absence of a reassuring human presence can actually increase discomfort. A skilled polygraph examiner reduces test anxiety through the pre-test interview, which normalises the experience and builds rapport — something the automated EyeDetect process cannot provide.
