VisionOS, Vision Pro and eye disorders

I did ask them at WWDC since I have both the conditions you list.

for nystagmus I was asking about eye tracking, but optic id is a good question also. For eye tracking they will have fall back to a hand based cursor, or mouse/trackpad.

for lazy eye (or non-binocular vision) they said it might just work.

it seems like they have had many discussions, but what made it into v1 was unclear. It seems like this is still a way away from a finished thing. They are not done building it yet.

but, the accessibility person I spoke with knew the name of nystagmus at least.

I also have these conditions. Both eyes are good, but I don't use them together. My brain has adjusted to this so that I can choose which eye to look through, but the eye I'm not using will float towards my nose. I have no doubt someone will write an app to practice converging the two eyes, which for someone like me would cause problems of double vision for some time before my brain adjusts, IF it adjusts. I can recognize spatial relations for the most part, I can drive and park, I can catch a ball, for instance. But, again, my brain has adjusted to this and uses different cues. But if I look through binoculars, I see two circles. Occasionally, it has merged into one larger circle, if I push the two lenses uncomfortably close together, but most of the time it doesn't work for me. I have tried VR goggles and it does produce a pseudo 3D effect, but again, I have to choose the left or right eye. So, I wonder, how would the device know which eye I'm using? Would I still be able to judge where in space the objects are other than by their size. And would that even work. I'd love to volunteer to help the developers work that out. But, as you mentioned, technomage, I'll bet they're well aware of this issue. It affects a lot of people.

I very much look forward to VisionOS becoming a platform for augmented-vision as well as augmented-reality!
