Connected glasses, which are wearable devices equipped with cameras, microphones, and sometimes augmented reality features, have sparked debate over privacy and legal use. In France, the judiciary has highlighted the risks associated with recording individuals without their consent, with potential penalties including up to two years in prison and a fine of 45,000 euros. The French data protection authority, CNIL, has introduced an action plan to address these concerns, emphasizing that the small lights on the glasses, which are meant to signal when recording is happening, can be easily hidden or disabled. This raises questions about how users can be informed when they are being recorded, which is a key issue in privacy law. In Sweden, connected glasses are already prohibited in schools, while in France and the European Union, there is no outright ban on purchasing or wearing them in public. However, capturing images of people in private spaces without their consent is illegal under both the Penal Code and the General Data Protection Regulation (GDPR). In public areas, the legality depends on factors like the context, the nature of the video, and how it is shared. In France, judicial investigations have been initiated following reports of influencers filming strangers in the street without permission. The CNIL has issued guidelines for users of connected glasses, advising them to inform others when recording, disable the function when not needed, and avoid using the devices in places where it might be unexpected. Several models are available on the market, some with cameras and others without. The Xreal One model offers high-quality displays and audio, though external headphones may be preferred. The Even Realities G2 model provides augmented reality features without a camera, while the Magic Connect from Afflelou functions as a hands-free kit with Bluetooth. The RayNeo Air 4 Pro is tailored for gaming with an immersive experience, and the Ray-Ban Meta Audio model focuses on audio and voice interaction without a camera. The Ray-Ban Meta model, which includes a camera, has drawn particular attention due to its potential for misuse. In France, connected glasses are treated similarly to smartphones under the GDPR and the Informatique et Libertés Act. Article 226-1 of the Penal Code penalizes the unauthorized capture or transmission of images in private spaces, with fines and prison sentences. In public areas, the legality depends on the specific circumstances, including the nature of the images and whether they could be considered harassment. The CNIL has noted that the light indicators on the glasses are not always effective in informing people being filmed, and the Paris prosecutor’s office has launched investigations into cases involving unauthorized recordings. Connected glasses come in various forms, with some models designed for specific purposes. Those without cameras, such as the Even Realities G2 or Magic Connect from Afflelou, are ideal for users who want to use them as a hands-free device without recording capabilities. Models with cameras, like the Ray-Ban Meta, allow users to take photos and videos but require strict adherence to legal standards and personal responsibility. For those seeking an immersive screen experience, the Xreal model is a suitable choice. Most of these glasses can be adapted with corrective lenses, though the availability and cost vary. It is advisable to consult an optician to ensure compatibility before making a purchase. For users who prefer camera-free models, the Magic Connect from Afflelou, the Even Realities G2, and the Ray-Ban Meta Audio are notable options at different price points.
