According to code discovered by MacRumors contributor Aaron Perris, the Apple Store app will use a facial scan to inform customers about the correct Vision Pro component sizes they need to order. The Vision Pro requires an appropriately sized Light Seal and Head Band to function correctly.
Apple has already used a Head Measure and Fit app to assist developers in testing Vision Pro to determine the proper size so that similar functionality will be built directly into the App Store. Light Seals and headbands are available in various sizes, and the ability to use a scan to determine size suggests that customers will not need to visit an Apple retail store to find the perfect fit.
The Vision Pro will come with a Solo Knit Band and a Dual Loop Band, the latter of which has an additional strap that goes over the head to distribute weight more evenly. A Light Seal and two Light Seal Cushions are also included. Customers who require ZEISS prescription lens inserts can upload or import their prescriptions from the Health app.
The code also suggests that Apple may allow the Vision Pro to be engraved, though it is unclear where an engraving might be possible.
Apple plans to release the Vision Pro on February 2, but pre-orders will begin on Friday, January 19 at 5:00 a.m. Pacific Time.
