NearLens
Detect nearby smart glasses before they detect you.
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.

I built NearLens because I could not find any iOS tool that told you whether smart glasses were nearby. The ones that existed were Android-only or required you to already know what you were looking for. The detection is not complicated: Ray-Ban Meta, Snap Spectacles, and EssilorLuxottica frames broadcast a Bluetooth LE signature to sync with their companion apps. That signature is identifiable. NearLens reads it, matches it against a known list of manufacturer IDs, and alerts you. No camera. No internet. No account. There is some irony in building a privacy tool specifically to protect people from the category of hardware I find most interesting. I thought about that longer than I probably should have. Free on the App Store. Ask me anything about how the BLE detection works or where this goes next.
