Facebook previously confirmed that the glasses are not an AR device and will not have a display (so probably like Snap Spectacles). Zuckerberg said "the glasses have their iconic form factor and they let you do some pretty neat things". The Ray-Ban's are the first step in Facebook's AR strategy, which also includes Project Aria, an experimental research AR prototype (full-fledged AR glasses). There have been rumors, including some confirmations from Facebook, for over a year now about Facebook's Ray-Ban smart glasses, specifically their partnership with EssilorLuxottica (RayBan's parent company). Augmented reality glasses are a key part of Facebook's new plans to build the "metaverse". Last year they said the glasses would launch in 2021 but now Zuckerberg didn't comment when the long-awaited glasses will drop. Link
