Hellenic Data Protection Authority warns of privacy risks from smart glasses

On October 20, 2026, the Hellenic Data Protection Authority issued a formal warning regarding the increasing use of smart glasses. The regulator highlighted that these wearable devices, which often resemble conventional spectacles, integrate advanced technologies including cameras, microphones, and artificial intelligence, allowing users to photograph, record audio and video, stream content live, and perform object recognition.

The primary concern cited by the authority is that third parties in the vicinity of a user may be recorded or have their personal data processed without their knowledge or consent. This risk is deemed particularly acute in sensitive environments such as hospitals, schools, and workplaces. By citing guidelines from the European Data Protection Board, the authority emphasized the need for users and manufacturers to strictly adhere to privacy standards to prevent unauthorized data collection and potential breaches of fundamental rights.

The announcement serves as an urgent call for public vigilance. The regulator advises that citizens must be aware of the capabilities of these devices to protect their personal privacy and maintain their civil liberties against potential unauthorized surveillance.
