As far as I can tell, these supposedly protect you from facial recognition because they reflect IR. I’m not an expert in security cameras, but don’t they only use IR at night? While they could technically run 24/7, that would burn out the LEDs in half the time.

These are also quite similar to the “anti-paparazi” reflective clothing. If you are interested in these as a statement piece, those might be of interest to you as well.

These seem like the developer came up with the function of the sunglasses after coming up with the sunglasses (after being inspired by the anti-paparazi clothes).

All in all, I don’t really see much value in these sunglasses; and I suppose I wouldn’t really be that concerned about facial recognition with proper masking safety, anyways.
