I thought of Steve Mann's "eye tap"

Was just about to post the same thing. Pretty nifty device, I've considered building my own for a while now. It's pretty simple.

Ghost in the shell and vision interception devices. Hopefully the devices these guys create don't come with an integrated killswitch.

I actually thought about the contact lenses in Torchwood that could overlay text on your vision.
