If you look at the Lumus Z-30 Optical Engine for AR glasses, it looks pretty much like an ordinary pair of glasses. But it's AR.
The Cupertino company was rumored to have abandoned AR glasses in 2019 and allegedly delayed them 'indefinitely' in 2023 before Apple launched the Vision Pro headset last year.
Apple’s plans for tethered glasses were nixed, but it may still have designs on AR glasses and its upcoming iPhone SE 4.
