No, they're able to detect that the LED light has been covered and will refuse to record. There's users who have taken them apart to try to disable the LED but that's not something most users will do, is likely to break the glasses.

10 years ago, I hated the idea of Google Glass, voice assistants, cloud doorbells, and their ilk. I thought the privacy zealots were reactionary but the general premise still was a bit icky - a little bit for the privacy, but mostly for the "weird nerd stuff" stigma.

5 years ago, I acquiesced started to let voice assistants into my home, thought the first edition of Meta Ray Bans were cool but not for me, and generally started to feel like these things were everywhere and nothing bad had come of it.

In the current year, I've gotten rid of all of my voice assistants, carefully blocked internet traffic for my IoT things, got rid of devices without local controllers, and would generally decline to be around someone who was wearing smart-camera glasses of any kind in the same way I'd decline to be around someone who was holding their phone up taking a video of me. The privacy zealots were right, it took some time - but we've learned that tech often isn't our benign anonymous friend. All it took was "tech" (the brand) completing its transition from benevolent cool hip industry to big business just like any other.
