Brief

Meta Ray-Ban smart glasses are framed here as a large-scale privacy threat, with the post combining sales figures, allegations about Meta's internal facial-recognition plans, and a Harvard student proof of concept that linked faces to personal data. The central news hook is a professor's countermeasure app, "Nearby Glasses," which warns users when the glasses are detected nearby via Bluetooth.

A professor built an app in 12 hours that Meta's billion dollar team never wanted to exist. It detects their Ray-Ban glasses nearby using Bluetooth. Your phone vibrates: "Smart Glasses are probably nearby." Meta's own internal memo said they'd launch facial recognition on the glasses "during a dynamic political environment" when civil rights groups would be too distracted to fight back. Harvard students already proved it works. They built glasses that reveal your name, phone number and home address just by looking at your face. Meta sold 7 million pairs last year. They look identical to normal glasses. The LED that blinks when recording? There are tutorials to disable it. One professor got fed up and built a counter in his spare time. It's Free & open source with zero ads. Detects within 50 feet outdoors. 32 feet in a crowd. Download: search "Nearby Glasses" on Google Play
