Blind Eye Society

The Blind Eye Society is a secret society operating in Gravity Falls, Oregon.

History
Over 30 years before Dipper and Mabel's arrival in Gravity Falls, Fiddleford McGucket founded the Blind Eye Society, intending to help relieve unwanted memories from others using a device he created and used continuously on himself. While McGucket's mind deteriorated from the negative side effects of the contraption, the society soldiered on in utter secrecy, now intent on keeping the citizens of Gravity Falls blissfully ignorant of the town's supernatural secrets. The Blind Eye Society eventually found itself under the command of Blind Ivan, a more conniving and malicious leader than his predecessor.



During the twins' visit to Gravity Falls, the society remains constantly present, and are shown erasing the memories of Robbie's encounter with Rumble McSkirmish after "Fight Fighters." A graffiti tag of the organization's symbol, an eye crossed out with an X, is seen in both "The Golf War" and "Soos and the Real Girl."



Lazy Susan becomes their latest victim in "Society of the Blind Eye," in which she is brought  before the society after witnessing a group of gnomes attempt to steal her pie. Meanwhile, Dipper, Mabel, Soos and Wendy accompany Old Man McGucket into the Gravity Falls Museum of History, believing the society to be responsible for his insanity. After a confrontation with Blind Ivan and its members, now revealed to be several notable townspeople, the kids are almost robbed of their entire summer, however McGucket returns to defeat Ivan and rescue his allies.

The Blind Eye Society is ultimately disbanded after its current members are ironically warped of their memories of any involvement with the organization, however Ivan unfortunately suffers long-term memory loss.

Headquarters


The Blind Eye Society operates beneath the Gravity Falls Museum of History, accessible via an entrance concealed by a fireplace. The underground chamber consists of both a large, circular room in which the memory erasing gun rests, as well as the Hall of the Forgotten, which houses the repressed and supernatural memories of the citizens of Gravity Falls.
