If some blind guy walked in with his Google Glass connected to his brain so he could see and was ask to remove them do you think the "please remove your glasses" would be acceptable? "But sir, I can't see without these as I'm blind. Are you really going to discriminate against blind people?".
Cameras embedded in eyes are coming. First they'll be for the blind. Then they'll be better than real eyes and probably be used for soldiers. Then they'll become fashion/must have along the same lines as a smartphone is today for most people. When friends can all see in infrared in the dark and you can't or can zoom in and read something small thing 600 meters away, or can drive through fog with their augmented reality eyes or recall whatever they need on demand few people will stay un-augmented.
I get that people don't want to be recorded. I just see it as they have no right not to be recorded because they have no right to choose how I remember things. If we invented a tech that could read my memory and produce a video then what? They've already invented digital memory that can be connect to brains. So if my brain was digital would that make a difference? If you don't want me to see you don't go out in public. Past that you have no right to decide how I remember you. Whether it's with my memory of you, a sketch I made, a picture I took or, a video I recorded. Those are all just augmented versions of me.
