I can imagine there are many use-cases for blind people, but I also think having some kind of visual indicator that "these glasses are recording" would be good, and I don't know what tools you use in public at the moment, but if you use, for example, a white cane, it might help people to understand "this person is using a camera for assistance". But yes, the fact that glasses manufacturers have already demonstrated they want to take every frame of data they can does sour their reputation

They have such an indication already, an LED light on the other side of the frame.

Of course you have to be able to spot that. And trust that it really doesn't record when it's off (note that it simply may be covered by the user)

I seem to recall that when the snapchat glasses were a thing, they had a very bright an obvious ring of LEDs around the camera itself, that were bright enough to shine through a sticker placed over them. Sure, there are still ways to defeat that, but it makes it a bit harder.

Also I just googled for what the light actually looks like when it's recording, and it's not even really that visible...
