The controversy behind the warning

Smart glasses with built-in cameras, such as camera-equipped Ray-Ban Wayfarer models, have faced public backlash over the possibility of secret photography or filming without the subject's knowledge. Concerns have centered on the discreet design of the devices, which can make recording difficult for bystanders to detect.

What the EU warning covers

The EU's warning relates to privacy obligations surrounding camera-equipped wearable devices rather than an outright ban. The claim that the bloc "warned about smart glasses" is therefore substantially accurate, but readers should note that it is a warning within existing privacy frameworks, not confirmed new legislation or enforcement against any single company or product line.

Limitations of the claim

Details such as the exact scope of the warning, which companies are directly affected, and whether further regulatory steps will follow remain unconfirmed in the available information. The characterization of the issue as a "covert filming controversy" reflects the public debate, not an established finding of widespread illegal recording.

Conclusion

The claim that the EU warned about smart glasses amid the covert filming controversy is broadly supported, with caveats about the nature and scope of the warning. Verdict: Mostly True
