A California judge sternly reprimanded members of Mark Zuckerberg’s legal team for wearing Ray-Ban Meta AI glasses—smart glasses equipped with a camera—while entering a Los Angeles courtroom on Wednesday for a high-profile trial examining the impact of social media on children. The incident drew sharp criticism from Judge Carolyn Kuhl, who presided over the case. She ordered anyone wearing the devices to remove them immediately, warning that any recording could lead to contempt of court charges. “If you’ve recorded anything, you must destroy it, or I will hold you in contempt,” the judge stated, emphasizing the seriousness of the breach. The glasses, which retail for between $299 and $799, include a camera capable of taking photos and recording video. Their use inside courtrooms is generally prohibited under Los Angeles County Superior Court rules, which restrict video and photography to protect the integrity of proceedings and the privacy of participants, including jurors. According to Jacob Ward, a technology journalist and host of the Rip Current Podcast, the incident was an “extraordinary misstep” by Meta. It remains unclear whether the glasses were active inside the courtroom or how long they were worn. Meta did not respond to a request for comment. The trial centers on allegations that Meta and Alphabet’s YouTube deliberately designed their platforms to foster compulsive use among young users. The plaintiff, identified only by her initials KGM, claims that her early and extensive use of social media led to addiction and significant harm to her mental health. Judge Kuhl also specifically prohibited the use of facial recognition technology to identify jurors, reinforcing the court’s strict stance on privacy and fairness. The case is one of the most significant legal challenges to tech companies’ practices around youth engagement and digital well-being.
