NearLens uses Bluetooth LE to detect smart glasses nearby. Ray-Ban Meta, Snap Spectacles, and EssilorLuxottica frames broadcast a wireless signature when they are on. NearLens reads that signal. No camera, no internet, no account required. Detection runs in the background. You get an alert. Most people have no practical way to know when someone near them is wearing recording-capable glasses. This app is a direct answer to that problem.
