AKRON, Ohio-- Police now have new technology to tell if someone is lying to them.

With this new equipment, the person never even has to say anything because the truth can be found in their eyes.

Bill Evans, of Poly-Tech Associates in Akron, said EyeDetect by Converus helps law enforcement officials determine who is telling the truth simply by looking at the person’s eye.

“It’s harder to lie than tell the truth,” Evans said. “When a person is in a position they have to lie the cognitive load is greatened, and so when they finally make that decision to lie, the pupil dilates.”

The human eye can’t catch when the pupil dilates, but EyeDetect can because it takes about 60 frames per second of your eye during the course of a 30-minute test.

“Tests show EyeDetect is 85 percent accurate on its own and when used with a polygraph test, its accuracy is about 98 percent,” Evans said.

Poly-Tech in Akron is the first to have the technology in Ohio. Evans said the test can be used to screen job applicants and also determine if suspects in crimes are guilty or innocent.

“It’s a great tool to have,” Evans said.
