There is actually a story out there with that exact thing.
Was the 4e "fashion" book.
Story focused on a Runner turned bodyguard some tween pop music star, or some such. He ends up taking down a totally innocent fan cause of the kid's "constant perv stare". Turns out the kid was born without eye receptors or some shit, making normal cybereyes a no-go, so the kid was using ultra sound to move about in crowds, and attributed to his "creeper stare"
