I always make it a point to explain that I’m not recording and that if I was the light would be on. And that if you try to cover it it actually will not allow you to record (which is true).
When the new Meta smart glasses were announced, I suddenly had >6 people comment on my old glasses. All the comments were positive, but it did make me more aware that I might get a negative reaction in the future.
The lens are pretty subtle, and they look like normal wayfarers. When the light comes on, as you make a recording or take a picture, then they notice, but not all of the time.
They offer better protection against "unsuspecting picture taking" than normal phones, as the light is vaguely tamper proof. I'm not sure they record if you take them off either.
but, my friend, why do you want to cover up the light?
