NearLens gives bystanders a limited signal that compatible smart glasses may be nearby. It does not show whether the glasses are recording or identify the person wearing them.
Smart glasses have many ordinary, legitimate uses. NearLens does not treat the people wearing them as suspects. The concern is how manufacturers design recording notices and bystander controls, not smart glasses as a category.

What NearLens does now
NearLens uses Core Bluetooth to scan advertising packets that nearby devices broadcast openly. It compares those packets with recognition data for compatible smart-glasses signals. The app does not pair with the glasses or decrypt their traffic.
When NearLens recognises a compatible signal, it can present an in-app alert with haptic feedback. Alerts can be snoozed. A result indicates likely device presence only; it does not confirm that a camera is recording.
Optional detection history supports Privacy Intelligence, which can surface repeat encounters and cluster events and produce an exportable report. Natural-language Q&A within Privacy Intelligence requires iOS 26, Apple Intelligence availability and compatible hardware, beginning with iPhone 15 Pro models.
NearLens requires no NearLens account. Its current App Store privacy label is Data Not Collected, and the listing shows no in-app purchases. The base app requires iOS 15.1 or later.
Detection limits
What a result can and cannot tell you
NearLens is not a universal detector. A nearby device may produce no result if it does not broadcast a recognisable Bluetooth signal. Results also depend on distance, interference, recognition data and device behaviour.
An alert is not proof that anyone is recording. It does not identify the wearer, reveal their intent or capture their image. It gives the iPhone user one limited signal that can inform a personal choice, including taking no action.
NearLens has been used in field observations, but those observations are not a controlled accuracy benchmark or a prevalence estimate. The current detection-history clearing interval has not been verified, so NearLens does not promise a fixed retention period here.
Technology context
What has been built or demonstrated
In January 2026, Meta shipped inactive code to its smart glasses for a facial-recognition feature internally called NameTag. The code was not available to users. Wired reported finding it in June, and Meta removed it within days. The New York Times reported in February on an internal document describing a possible launch plan. In August, 404 Media reported that Meta had filed a patent for a related feature.
The ACLU and 75 other organisations had earlier written to Meta opposing real-time facial recognition on smart glasses. In a separate 2024 demonstration, two Harvard students combined Meta smart glasses with PimEyes and public records to return names and other personal details during live interactions. Meta said its glasses contained no facial-recognition technology and that the demonstration used publicly available software with a camera that could have been any camera.
These examples document development, reporting or demonstration. They do not establish that a facial-recognition feature is available to consumers.
Visible notice
What a bystander can see
Ray-Ban Meta glasses include a small white recording light. It can be difficult to see in ambient conditions even when it works as designed. At least one documented physical modification has removed the light while leaving recording available.
The illustration combines capabilities that have been built or demonstrated. It does not show a standard consumer feature, and a public consumer implementation remains unlaunched. For a bystander, the visible safeguard is still a small light on eyewear designed to look ordinary.
Why NearLens exists
A limited signal for bystanders
NearLens does not solve bystander privacy. It addresses a narrower problem: a bystander may have no independent signal that recording-capable eyewear is nearby. A raised phone is easy to notice; glasses can look like ordinary eyewear.
Hardware-level consent and clearer bystander notice would address the issue closer to its source. NearLens provides a limited indication of likely device presence without identifying the person wearing it.
About
About NearLens
NearLens is an iOS bystander-awareness app developed in Ottawa, Canada. It scans for Bluetooth signals that may indicate compatible smart glasses nearby. The app's current App Store privacy label is Data Not Collected. The website has separate, consent-controlled processing described in the Privacy Policy. NearLens is available on the App Store and at nearlens.app.
