The Invisible Lens: Why NearLens is a Necessary Shield in a Surveillance State

As Meta CEO Mark Zuckerberg hails smart glasses as a fast-growing consumer category, a new app by Marcos Rezende exposes the gap between tech novelty and the right to privacy.
OPINION: For the venture capitalists and early adopters, the rise of camera-equipped eyewear is a thrilling leap toward the future of wearable tech. But for the rest of us—especially those who cannot simply opt-out of the public sphere—it is the arrival of a discreet, omnipresent surveillance state.
While Meta CEO Mark Zuckerberg describes these devices as one of the fastest-growing consumer electronics categories ever, the reality for the average person is a shrinking sense of bodily autonomy. When recording becomes invisible, privacy is no longer a choice; it is a luxury.
This is the tension that Marcos Rezende, a Brazilian Canadian product and UX designer, is attempting to address. Rezende, who currently serves as a senior product designer at the Kitchener-Waterloo event marketing platform Hive and previously worked at Microsoft, has launched a free iOS app called NearLens. As BetaKit first reported, the application is designed to help users navigate an environment where smart glasses, such as the Ray-Ban Meta, are becoming increasingly difficult to spot.
NearLens functions by listening for Bluetooth signals associated with camera-equipped eyewear and tracking those matches in real time. As App Developer Magazine noted, the app serves as a practical response to the growing gap in how these devices impact everyday privacy. In an interview with BetaKit, Rezende explained that the app provides a signal when users are in the vicinity of glasses that could be actively recording.
Rezende’s own testing highlights the unpredictability of this surveillance. BetaKit reports that during a three-hour window at Ottawa’s TD Place Arena, NearLens detected 15 signals among 7,000 people, while a test at Meridian Theatres returned zero matches. While these numbers may seem small to a tech executive, they represent a fundamental shift in how we occupy public space.
Furthermore, the scale of this intrusion is poised to explode. A report from Business of Fashion-McKinsey projects that smart glasses sales will quadruple by 2026, driven by the availability of cheaper and sleeker models. Meta has already noted that daily usage of its smart glasses has tripled year-over-year.
Crucially, Rezende has built NearLens to avoid becoming part of the problem. BetaKit reports that the app has no backend, requires no accounts, does not compile analytics, and avoids third-party software development kits. Rezende claims the app does not access microphones or cameras, nor does it identify the wearers or confirm if footage is being captured.
Rezende views NearLens as a temporary fix until society decides how to regulate these devices. But we cannot afford to wait for the industry to self-regulate. When the tools of surveillance are marketed as fashion accessories, the burden of privacy is unfairly shifted onto the victim. NearLens isn't just a clever piece of software; it is a desperate signal that our right to exist unseen is being eroded by the 'fastest-growing' trends of the tech elite.
