It should be illegal to record your face through 'perv glasses' without consent.

What about phone cameras?

I'm curious if/how people make a distinction, I really like the UX of AR (as found in the HoloLens 2), hardware is getting close to where I might pick something up again (FOV has hardly budged, form factor way down)

I suspect smart glasses will be a normal thing one day, the experience is orders of magnitude better than looking down at a tiny touch screen

Obviously the difference is stealth.

Phone cameras can and are used stealthily as well, it's not hard to fake texting while actually taking a photo, setting aside those which happen that you are not looking their way to notice. On the flip side, with smart glasses, others cannot look over your shoulder at your text messages. There are areas where privacy increases

I just don't think this line of thinking will hold up long term. Pervs are going to perv anyway, but the UX improvement for the average person will be that 10x better than they will take the downsides for the outsized upsides they get.

I'm personally more concerned about AR ads when it comes to smart glasses

On the flip side, with smart glasses, others cannot look over your shoulder at your text messages. There are areas where privacy increases

So, privacy for thee but not for me?

This is what makes these sorts of devices so objectionable. They're people subjecting unconsenting others to surveillance for nothing more than their own convenience. And surveillance that is much more difficult to detect.
