We took apart the Vision Pro, and it is a phenomenal feat of engineering! There is just so much packed in this headset. Some highlights: 
The curved bubble shell is a real bear to get open. We're pretty good at this kind of thing, and still managed to (slightly) break the glass. I would love to see the manufacturing process for this complex shape!
With the glass off, we can start to see how the EyeSight system works. There's a curved OLED panel with a series of lenticular lenses.
When the EyeSight displays your eyes, it isn’t just displaying a single video feed of your eyes; it’s showing a bunch of videos of your eyes. Exploring inside the glass shell, we found three layers for the front-facing display: a widening layer, a lenticular layer, and the OLED.
Apple wanted a lifelike, 3D view of your eyes, so they set up custom prisms to create the stereoscopic effect. It's hard to photograph what's going on, so here's a diagram.
But how does the lens actually work? Why I'm glad you asked! Good thing we had a trusty @Evident_LS microscope to see the physical structure of the lenticular lens. The effect is similar to those toy cards that change the image depending on your viewing angle.
@Evident_LS Going inside even further, you can see the second set of displays underneath. There is a massive amount of complexity in here, far more ribbon cables and connected sensors than in your phone.
@Evident_LS Our full teardown has a lot more insight, along with 360-rays from @CreativeElctrn ifixit.com/News/90137/vis…
