I’ve heard of approaches using pulsed IR along with a Mk.1 Human Eyeball to detect the incident reflections, sometimes with the assistance of a filter. Glasses seem like a good form factor for that kind of thing.
Of course, the detecting person’s anti-camera glasses may well light up on the surveiller’s recording, too…
