Meta’s Ray-Ban smart glasses powered by artificial intelligence have become one of the most popular tech devices in recent years. However, their commercial success has also sparked intense debate about privacy, the use of personal data, and the hidden work of those who review the recorded content.

The growth of smart glasses and the debate over privacy

Meta’s Ray-Ban smart glasses have experienced remarkable growth in popularity in recent years. In 2025, more than seven million pairs were sold, a figure that contrasts sharply with the two million sold across 2023 and 2024 combined. This increase reflects the growing public interest in wearable technology capable of combining recording features, communication, and artificial intelligence.

The device allows users to capture images and videos from a first-person perspective thanks to a built-in camera and microphone. In addition, through Meta’s AI model, the glasses can analyze the user’s surroundings, answer questions, or interact with elements of the real world. This technological integration promises a more immersive and practical digital experience.

However, technological progress has also raised concerns among privacy experts and digital rights organizations. Some critics warn that features such as facial recognition could have dangerous consequences, especially if combined with surveillance systems or used by authorities.

Another point of concern is Meta’s track record regarding the protection of user data. For many analysts, the development of devices capable of continuously recording the surrounding environment presents new challenges regarding how that data is stored, processed, and used.

The debate intensifies because the glasses allow everyday situations to be recorded without nearby people necessarily being aware of it. This raises important questions about consent, privacy in public spaces, and the possibility that large volumes of personal data could end up being analyzed by artificial intelligence systems.

The invisible work of data annotators

Behind the operation of many artificial intelligence systems there is a process that remains largely invisible to users: data labeling. In this process, human workers review and classify content to help train AI models.

In Meta’s case, part of the material recorded with the smart glasses is sent to external contractors for review. These workers, located in countries such as Kenya, analyze the videos and annotate details that help improve artificial intelligence recognition and analysis systems.

According to testimonies collected by Swedish media outlets, some workers have had to review highly intimate and sensitive content. In some cases, the videos show private situations such as people changing clothes, using the bathroom, or scenes of a sexual nature.

There have also been reports of recordings showing bank cards, users watching pornography, or even extremely personal moments that were apparently recorded without the full awareness of the people involved.

Several workers say they feel uncomfortable with this type of material, but explain that they must review it to fulfill their job duties. Some have even stated that questioning the process could put their employment at risk, highlighting the pressures faced by those who work in content moderation or annotation.

This type of work resembles that of social media content moderators, who for years have had to review disturbing material in order to keep digital platforms functioning.

The risks of sharing data with artificial intelligence systems

One of the most controversial aspects of using smart glasses is that many of their functions depend on sending data to Meta’s servers. To fully use the device’s artificial intelligence capabilities, users must agree to have their interactions processed and analyzed.

Meta’s terms of use state that the company may review interactions with its AI systems, including conversations or content generated during the use of the device. This review may be carried out through automated processes or through human review.

The document also warns that users should not share information they do not want artificial intelligence systems to store or use later. However, many users are probably unaware of the true scope of this data collection.

Data protection specialists point out that once information enters artificial intelligence models, the user’s control over that content is significantly reduced. This raises questions about how the data may be reused and how long it remains within AI training systems.

Furthermore, experts warn that the growth of wearable devices with constant recording capabilities could amplify problems related to digital privacy. Every interaction, image, or conversation could potentially become material used to train new artificial intelligence technologies.

The rise of smart glasses demonstrates the enormous potential of portable artificial intelligence, but it also reveals significant ethical challenges. From user privacy to the invisible work of data annotators, the development of these technologies raises key questions about transparency, consent, and control over personal information.
