Right but if they stand near you and film you with a phone without directly interacting with you, it’s extremely difficult to notice that you’re being filmed.
If someone stands in front of you and interacts with you, firstly the camera in these glasses is not hidden and the glasses themselves are quite distinctive, and secondly, a light comes on exactly where you would be looking as you interact - next to their eyes.
On those two points, I’d argue that they’re exactly the same as phones or other cameras when it comes to being able to secretly record.
They’re nothing like glasses from spy novels, they’re extremely noticeable.
