An improvement on the original (made by Timothy Leary), as these glasses do not impede free will. MacPherson used them to hide objects on a higher spectrum so that only those who had copies of the glasses could see what he wanted hidden. MacPherson also used them as a form of catalog for the artifacts he was selling on the black market. When the glasses are worn, the wearer can see the date, time, and location of the place where MacPherson is selling his stolen artifacts printed on the glasses case.
Artie, Pete and Myka found them and discovered the information about the auction in MacPherson.
