You have the right to opt out of facial recognition tech. Here’s how.
Travelers can opt out of facial recognition at US airports by requesting manual ID verification, though resistance or intimidation may occur.
Facial recognition poses privacy risks, including potential data breaches, misidentification, and normalization of surveillance.
The Algorithmic Justice League's "Freedom Flyers" campaign aims to raise awareness of these issues and encourage passengers to exercise their right to opt out.
Get clear ones. Most (all?) of those security cameras use IR illumination to ID you, so you can have lenses that allow visible light through, but mess up IR scanning. I think you can get them w/ prescription lenses if you email the creator, so you can legitimately tell them you need your glasses to see (if you need a prescription, that is).
I'm less worried about the face scanning (you can opt-out, as you said), I'm more worried about the camera scanning in other parts of the airport. The glasses combat the most common form of face scanning, which uses IR illumination. It also works at grocery stores and whatnot, which is especially important if you're a POC and likely to be racially profiled as a shoplifter (I've read some horror stories).
It does paint a bright red target on my chest since they show up as a massive bright light source on IR feeds (if a security guard happens to watch), so it's more a form of protest than anything.
