I made an app.
play.google.com/store/apps/details?id=ch.pocketpc.nearbyglasses
Nearby Glasses is here to warn you when smart glasses are nearby.
I hope it's useful for someone.
The app is now open source (AGPL-3.0), the app is free and rather simple
github.com/yjeanrenaud/yj_nearbyglasses
It's also downloadable outside the Play Store. iOS port is in the making. F-Droid is an option, will have to look into that

Smart Glasses are probably nearby
Device: Unknown
RSSI: -42 dBm
Reason: Meta Company ID (0x058E)
Company: Meta Platforms, Inc.
This app notifies you when smart glasses are nearby. It uses company identificators in the Bluetooth data sent out by these. Therefore, there likely are false positives (e.g. from VR headsets). Hence, please proceed with caution when approaching a person nearby wearing glasses. They might just be regular glasses, despite this app's warning.
