EyeDetect testing: all about the eye-based lie detector — price, accuracy and how it works

EyeDetect testing is a modern method of deception detection that analyses a person’s eye movements and the brain’s cognitive reactions while they answer questions. Unlike the classic polygraph, EyeDetect is a contact-free lie detector: it needs no sensors attached and delivers a result much faster.

Need a test rather than theory? Take the VerifEye online test — from 2,500 UAH (≈ €50), no office visit — or calculate the cost of a polygraph test.

Today EyeDetect technology is widely used for staff screening, internal investigations, financial security and private tests, and it is gradually becoming a real alternative to the polygraph.

What EyeDetect is and how it works

EyeDetect is a psychophysiological deception detection system developed by Converus.
The technology is based on oculography: the science of eye movements and pupil reactions.

How EyeDetect works, in simple terms

When a person lies, their brain works under an increased cognitive load. This automatically shows up as:

• changes in pupil diameter;
• the speed of eye movements;
• blink rate;
• delays in reading and answering.

These reactions cannot be consciously controlled, unlike breathing or facial expressions.

The technology side

• a highly sensitive camera tracks the eyes;
• software analyses thousands of parameters;
• an AI algorithm produces the result without human involvement.

EyeDetect or polygraph: comparing the technologies

👉 Bottom line: EyeDetect does not replace the polygraph in complex examinations, but it far outperforms it as a fast, objective and scalable screening tool.

Main uses of EyeDetect

👔 HR and recruitment

• pre-employment screening of candidates;
• uncovering theft, abuse and hidden risks;
• mass screening of frontline staff.

🕵️ Internal investigations

• quickly narrowing down the circle of suspects;
• a supporting tool for management decisions.

🏦 Business and finance

• internal security;
• reducing fraud risks;
• vetting partners and employees.

👤 Private tests

• proving innocence;
• family and personal matters (with the consent of those involved).

Can EyeDetect be fooled? Myths and reality

This is one of the most popular Google searches.

The short answer:
👉 EyeDetect is extremely hard to fool.

Why?

EyeDetect analyses involuntary eye reactions, which are regulated by the autonomic nervous system.
Even if a person:

• knows the questions;
• tries to “calm down”;
• trains specially for it,

— the cognitive load of lying is still recorded.

⚠️ Important: EyeDetect is not a “verdict” but a verification tool, used together with an analysis of the facts.

How EyeDetect testing works: step by step

1. Preliminary briefing.
2. Calibrating the camera to the eyes.
3. A practice round, a test on a number you have written down.
4. The main test (True/False questions).
5. Automatic data processing.
6. Receiving the result as a report (PDF).

⏱ Total time: up to 45 minutes, including the result.

EyeDetect test price and what it depends on

The cost of EyeDetect testing depends on:

• the number of people;
• the complexity and number of questions;
• the purpose of the test (HR, investigation, private);
• the region where it takes place.

👉 As a guide: from 5,500 UAH (≈ €110) per test; the test is taken at the station in Lviv (the exact price is set individually and depends on the number of people and the subject of the test).

Frequently asked questions (FAQ)

Is EyeDetect a contact-free lie detector?
Yes, no sensors are placed on the body.

Is EyeDetect testing legal?
Yes, provided the examinee gives voluntary consent.

Which is more accurate — EyeDetect or the polygraph?
They are different tools. EyeDetect is more effective for quick screening.

Is EyeDetect suitable for Ukraine?
Yes, the technology is widely used and adapted to local conditions.

Conclusion: is an EyeDetect test worth taking?

EyeDetect is a modern, contact-free and scientifically grounded method of deception detection.
It does not replace in-depth examinations, but it is ideal for:

• quick checks;
• mass screening;
• reducing business risks.

👉 If you need a fast and objective eye-based lie detector, EyeDetect testing is the optimal solution.
