Someone is looking straight at you through a pair of glasses. Are they simply making eye contact, or could a camera be pointed your way? You cannot reliably tell from appearance alone. Unlike a phone, glasses need no obvious hand movement to aim.
Tiny sensors are real, but the whole camera is not a speck
OMNIVISION announced a 0.575 mm OV6948 image sensor in 2019. Its camera module is small too, but that measurement does not include an entire battery-powered recording system. Miniaturisation does not erase limits on power, storage or image quality.
A recording light helps; it is not a universal verdict
Some commercial smart glasses show an indicator when recording. That is a welcome design feature, not a rule every device or every camera function must follow. No visible light is neither proof of recording nor proof that nothing is happening.
Better rules beat suspicious glances
Shared spaces need clear guidance on when recording is acceptable. Wearers should tell people before filming and consider consent before sharing. If you are worried, ask staff rather than confronting someone on the strength of a guess.
The most useful upgrade may not be a smaller camera. It may be a clearer way for everyone nearby to know what it is doing.
