Blind Eye Society

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

History
The Blindeye Society is first mentioned in a cryptogram in the video game Rumble's Revenge, in which Bill Cipher alludes to the existence of a secret society within the town. The society is again referenced in a cryptogram in "Gideon Rises," which reads "SEARCH FOR THE BLINDEYE" when decoded.

Later, in both "The Golf War" and "Soos and the Real Girl," the symbol of the society, a crossed-out eye, is shown grafitied on both a wall and a dumpster, respectively.

The Blindeye Society makes its physical debut in "Society of the Blind Eye."
