Right, so it’s kind of a telepathic focusing lens.
I guess that might have been an inspiration for the Force. Although it has more of a PT feel to it (e.g. Midichlorians being needed to tap into the Force).
Dune was a bigger influence for the Force, and, as I spoke of earlier, was the reason they changed it in the Lynch film to being a device they use rather than a “force”-like thing.
