Facebook's sunglasses have been the subject of rumors since 2019. Back then, sources told CNBC that Facebook was working with Ray-Ban owner EssilorLuxottica on AR eyewear nicknamed "Orion." The glasses were billed as a full-fledged phone replacement on which you could take calls, see information and even broadcast livestreams. That inevitably drew comparisons to Google Glass (another Luxottica collab) instead of the phone-tethered Spectacles from Snap. Last year, Hugo Barra, then VP VR at Facebook Reality Labs, confirmed that the glasses would land in 2021. But, we haven't heard much since.
