Just break the law and hope the other side is too poor to sue. Basically like everywhere else on the planet.

In the case of France there's two possible broken laws (not a lawyer btw):

• If the glasses wearer upload the video/photo online, you are one of the primary subject of the frame (aka not just in he background), and didn't consent to being on the internet, you can sue.

• Companies must legally ask you for your concent to collect personal and identifying information. If the video/photo is sent to meta for big data/ai training, they must ask for consent

Edit: "primary subject" is kinda vague and may change depending on the context. If you do a VLOG and someone does something funny in the background, not aware of the camera, and the video is re-uploaded to only feature the guy, then it becomes the primary subject, and must be asked for concent

In most EU countries, the act of filming in public places is perfectly legal as there is "no expectation of privacy". It only becomes a legal issue if you publish those videos, and even then it usually requires the person to be the focus of the video.

I think it's only France where it's explicitly banned. Mostly because otherwise CCTV cameras are legally complicated.
