Didn't Google Glass do the exact same thing and failed? Not because of the technology issues, but social issues.

People nowadays want to disconnect from technology more, not to have it even closer.

Their problem was that they didn't look like normal sunglasses, so people were immediately intrigued/suspicious of them. Although these have the little light if you're recording, the amount of instagram videos where creators are using these and the random people they're directly talking to don't notice, should tell you all.

The rise of smart accessories (especially watches) should tell you that a lot of people don't want to disconnect

Google Glass looked unusual and was nerd-coded. Social norms are extremely strong. The only way something that looks like Google Glass would take off is if the tech is established with the well-to-do having elegant devices, and then something like Google Glass becomes working-class-coded.

Bet you GG though actually treated your PII with respect

For all my numerous complaints about Google

Google Glass launched too early, when people cared more about privacy.
