What situations call for "Pervert glasses?"
i dont want to have a camera stuck to my face that i dont really control in order to see
This may be a body camera or a camera built into glasses. That is a very legit usecase as far as I'm concerned.
There are other professions in which such a device would be a net benefit, that was just a simple example.
what would these offer that can't already be done w/ their existing solutions, outside of streaming data to evil megacorps?
If it was about the latter then I'd agree that there is no usecase for them
