This is for self-defense. Not that I live in a country where they (officially) ship, but just in case…
Regarding “how to tell them apart from regular glasses”, this question is mainly about Ray-Ban Blayzer Optics:
Ray-Ban Scriber Optics:
And Ray-Ban Display:
Because these are by far the hardest to identify. Other glasses either have a clearly visible “RayBan” text in the top left corner (which for the pictured ones isn’t clearly visible) or can be identified just by their style.
Good luck providing those links in the court. It is just one level more sane than mentioning voices in your head.

The problem is not proving in court how unethical these are. There is plenty of proof and knowledge of that, even among authorities.
The problem is, people don’t care and the manufacturers know exactly how to play these people.
What would actually not hold up in court is the matter of proportionality. There isn’t a single juror or judge that would buy OP’s interpretation that invasion of privacy merits destruction of property.
I’m not saying anything about proving something about the glasses. If you attack someone and break their property, the court will be about this first, and what that property was will be secondary. Don’t attack people, wven if they are assholes. Personal privacy crimes are not felony territory in most countries, assault is
