Strange Science: New lie detector looks at a person eyes to gauge the truth

HOUSTON -- It turns out that your eyes do give you away after all. Science has found out that when someone lies, their pupils dilate ever so slightly. You can't see this change with the naked eye, but according to researchers, it happens every time someone lies.

Now a company called Converus is giving this pupil change a closer look with their EyeDetect. A program the company claims can catch someone in a flat-out fib...just by looking at their eyes.

EyeDetect spokesman Neal Harris says, " EyeDetect uses a very precise inferred sensor, and they can measure pupil dilation down to a 100th of a millimeter."

This ocular technology might be new, but just like the good old-fashioned polygraph machine, it all starts with a simple question.

According to Harris, "When we're asking questions of an individual, we can determine if they're being deceptive or truthful based on how much pupil dilation is occurring immediately after they answer the question."

Converus claims their new lie detector could one day assist police with keeping an eye on crime.

Harris adds, "Our hope is that our technology can help make us safer, and help protect us from those that would want to cause harm." Truth be told, EyeDetect "looks" good to us.
