A long-standing limitation of the Apple Vision Pro was its lack of support for prism-valued prescriptions. However, with visionOS 26, you can now enter the prism values from your prescription and visionOS will adjust via software.

Since the launch of Apple Vision Pro, there has been a warning for those looking to purchase ZEISS Optical Inserts: a very small percentage of people have a prism value added to their eyeglass prescription. At this time, ZEISS Optical Inserts based on a prescription that includes a prism value are not available. If you have a prism value, it will be listed on your prescription and will be noted separately from the sphere, cylinder, axis, and ADD values. If you are unsure whether your prescription includes a prism, please consult an eye care professional.
But now, with visionOS 26, that warning is removed and a new feature is added: Digital Prism Correction. If you are in the US or certain US territories (American Samoa, Guam, Northern Mariana Islands, Puerto Rico, US Minor Outlying Islands, and US Virgin Islands), you can open Settings and select the new option to “Add Prism Prescription.”

You will then be able to enter your prism prescription values. However, there are limits: the Digital Prism Correction feature supports prism prescriptions up to 7.75 Prism Diopters (PD) in the horizontal and/or vertical direction — i.e., base-in (BI), base-out (BO), base-up (BU), and base-down (BD) — and the equivalent range in the polar direction (0-359°), per eye.
Your prism values are linked to your optical inserts, so you can use multiple sets of inserts with one device and you can save them to your guest profile.

It's great to see Apple continuing to support Apple Vision Pro and working to expand the number of people who can use it. We hope this feature will arrive outside the US soon!
