- An Android app named Nearby Glasses can detect and alert users when nearby smart glasses or Bluetooth-enabled recording devices are present.
- The app scans for Bluetooth signals from manufacturers like Meta (Ray-Ban) and Snap, and users can add custom identifiers to detect other devices.
- It was created by Yves Jeanrenaud, inspired by reports on surveillance abuses, such as using smart glasses in immigration raids and harassment.
- Jeanrenaud criticizes smart glasses as privacy-invasive, especially citing Meta's default face recognition feature.
- The app may produce false positives, like mistaking Meta's VR headsets for smart glasses, but these are usually more noticeable.
- Testing showed the app works effectively, detecting Apple devices via a custom Bluetooth identifier.
- Jeanrenaud views the app as a 'desperate act of resistance' against social problems amplified by technology.
- Snap claims its glasses have privacy features like LED indicators, but did not detail prevention of unwanted recordings.
- Meta did not comment on the app or privacy concerns.
