Nearby Lens: Glasses Detector

NEARBY LENS — SMART GLASSES DETECTOR

Are there smart glasses near you right now? Nearby Lens scans for Bluetooth Low Energy signals from popular smart glasses brands and alerts you when a pair is detected in range — no pairing, no setup, no internet required.

━━━━━━━━━━━━━━━
WHAT IT DETECTS
━━━━━━━━━━━━━━━

Ray-Ban Meta smart glasses — the most widely worn AI glasses on the market, capable of recording video
Snap Spectacles — Snapchat's camera glasses, worn by millions
Bose Frames and other BLE-broadcasting audio glasses
Other wearable devices that broadcast identifiable Bluetooth signatures

The detection database is updated regularly as new smart glasses models are released.

HOW IT WORKS
━━━━━━━━━━━━━━━

Open Nearby Lens → tap Scan → the app listens for BLE broadcasts in your immediate environment. When a known smart glasses signature is detected, you receive an instant alert showing the device type, estimated signal strength, and proximity category.

The scan is entirely passive — Nearby Lens never connects to any device. It simply receives publicly broadcast BLE advertisements, the same way any Bluetooth receiver does. No interaction with the target device. No interference. No footprint left.

━━━━━━━━━━━━━━━
PROXIMITY ESTIMATION
━━━━━━━━━━━━━━━

Signal strength (RSSI) is used to estimate how close a detected device is:

Immediate — under 1 metre
Near — 1 to 3 metres
Far — beyond 3 metres

Note: walls, interference, and device positioning affect accuracy. Proximity is an estimate, not a precise measurement.

━━━━━━━━━━━━━━━
BACKGROUND SCANNING
━━━━━━━━━━━━━━━

Enable background scanning to receive alerts even when the app is not open. Your phone continues passively listening and notifies you the moment a known device is detected nearby — in meetings, in cafes, in elevators, anywhere.

USE CASES
━━━━━━━━━━━━━━━

Privacy-aware individuals who want to know when recording-capable devices are in their vicinity
Security and compliance teams assessing wearable device presence in restricted areas
Tech enthusiasts tracking the real-world spread of AI and camera wearables
Journalists and researchers studying smart glasses adoption in public spaces
Anyone concerned about being recorded without their knowledge or consent

━━━━━━━━━━━━━━━
LIMITATIONS (HONEST)
━━━━━━━━━━━━━━━

Nearby Lens detects BLE broadcasts. If smart glasses have Bluetooth disabled or are in airplane mode, they will not be detected. Detection is based on manufacturer BLE signatures — unknown or uncatalogued devices may not be identified by name, though their signal will still appear.

━━━━━━━━━━━━━━━
PRIVACY
━━━━━━━━━━━━━━━

Nearby Lens identifies device types only — it never identifies individuals. No data is collected, stored, or transmitted off your device. All scanning is local. No account required. GDPR-compliant.

FREQUENTLY ASKED QUESTIONS
━━━━━━━━━━━━━━━

Can Nearby Lens identify who is wearing the glasses?
No. It detects the device type only — never the person wearing it.

Does it work if the glasses are in a bag or pocket?
BLE signals pass through fabric and most materials, so yes — detection range applies regardless.

Does the scan drain my battery?
BLE scanning is very low power. Foreground scanning has minimal impact. Background scanning uses optimised duty cycles to reduce battery drain.

Will it work in a crowd?
Yes. Multiple devices can be detected simultaneously. Each appears as a separate entry.

As smart glasses become mainstream, knowing when cameras are around you matters more than ever. Nearby Lens gives you that awareness — quietly, instantly, and privately.
