The medical subjects were made to wear silver electronic eyewear that tapped into their brains and could record their thoughts. I think they may have been experimenting with hi-tech suggestive advertising. Seems like there were flashes of light accompanied by medical devices scribbling furiously as the person's mind was being tapped.

Anyone recall this movie? I'm mainly trying to remember who the lead actor was because I saw his look-alike out walking yesterday : )

Here's a very wild guess:

Looker (1981)
Starring Albert Finney, Susan Dey, James Coburn
