The Hypno-goggles are a mask-like device that Evelyn Deavor uses to put people under her control when she is in need of minions. Her hypotonic screens can only work when eyes are on them at all times. She used them to control several supers, including Helen Parr, Bob Parr and Frozone. It is later revealed that she was using them to control the Screenslaver. The goggles were cleverly hidden in the eyepiece of his mask. In order to save the superheroes from mind control, the super kids distract them and break the pairs of goggles.
