Ray-Ban Meta smart glasses are just one of many wearable tech devices on the market. The glasses, which first launched in 2021, are a collaboration between Meta and Italian-French eyewear company EssilorLuxottica, which owns Ray-Ban among many other brands.

The smart glasses feature two small cameras, open-ear speakers, a microphone and a touch panel built into the temple of the glasses. To access these features, users must pair them to their mobile phone using the Meta View app. Users can take photos or videos with the camera, listen to music from their phone and livestream to Meta's social media platforms.

Users can operate the glasses using spoken commands or the built-in Meta AI assistant, which responds to prompts like "hey Meta." For example, users can say, "hey Meta, look and…" followed by questions about their surroundings.

To take a photo or video, users press and hold a button on the frame, which activates an LED in the front of the glasses. The LED signals to others that the camera is actively capturing a photo or video. If the LED is covered, the camera won't work and the user will be prompted by the Meta AI assistant to uncover it.

Although the LED helps to signal that the camera is in operation, the relatively small size of the LED garnered criticism from privacy regulators in Europe.
