Nearby Lens – Detect smart glasses recording near you

Summary: Nearby Lens provides real-time alerts when camera-enabled smart glasses like Ray-Ban Meta or Snap Spectacles are nearby, using Bluetooth Low Energy (BLE) signal detection without requiring accounts or GPS. It runs in the background on Android and iOS, ensuring privacy by processing data entirely on-device.

What it does

The app passively listens for BLE signals broadcast by smart glasses, identifying models such as Ray-Ban Meta, Snap Spectacles, and Bose Frames with confidence scores to minimize false positives. It does not require pairing and hashes device identifiers locally.

Who it's for

It is designed for users concerned about unnoticed video recording in sensitive environments like meetings, classrooms, or private spaces.

Why it matters

Nearby Lens addresses the lack of visible indicators on recording smart glasses by alerting users to their presence nearby, enhancing privacy awareness.
