Meta's latest update to its Ray-Ban smart glasses includes an AI-powered nutrition tracking feature that can analyze the user's meals through photos or voice commands, automatically logging calorie and ingredient details. While touted as a convenient health tool, the always-on camera analysis required for automated tracking has raised significant privacy concerns.

Why it matters

This new feature positions Meta's smart glasses as a persistent dietary surveillance tool, transforming everyday eyewear into a means of constant food monitoring. The privacy implications of this technology raise questions about the balance between convenience and personal data privacy, especially as Meta expands its ecosystem of connected devices.

The details

The nutrition tracking feature works by allowing users to photograph their meals or simply tell the glasses what they're eating. Meta's AI then extracts details like calories, macros, and ingredients, building a personalized food log in the companion Meta AI app. Future updates promise even more automated tracking, with the glasses potentially being able to 'understand what you're eating' without any user prompts, requiring constant camera analysis of the user's visual field.

• The nutrition tracking feature will roll out soon for users 18 and older in the US.
• Higher-end Meta Ray-Ban Display glasses will get the feature this summer.

What’s next

Meta plans to expand the nutrition tracking feature to its higher-end Ray-Ban Display glasses this summer, further integrating the technology into its growing ecosystem of connected devices.
