Like a grandma pinching your cheeks, Apple needs to get a good look at you before you get any sweet treats. That's to say, you need to scan your face first before you can order an Apple Vision Pro.
In an email, Apple explained that "When you order Apple Vision Pro, you'll need to scan your face with an iPhone or iPad with Face ID." This sounds extreme, but I think it makes sense, having used some of the best VR headsets, getting the right fit can be the difference between a good and bad experience (and alleviate nausea too!).
