How to tell if someone is wearing smart glasses: five clues

As smart glasses draw attention as a next-generation consumer device, interest is also growing in how to identify them. Their appearance can resemble regular eyewear, making them hard to spot. But clues may be found in thicker frames, small camera parts and charging ports, as well as indicator lights that may turn on during recording. User behaviour and apps that scan nearby Bluetooth devices can help, though they can be unreliable and prone to errors.

Battery capacity and real-world range can vary with load, terrain and weather. Prices can run into thousands of dollars. Maintenance and parts availability, including hinges and batteries, also matter.
