Eye control. With default settings, the primary way to select what to click on Vision Pro is entirely through moving your eyes. I thought this would be a dealbreaker for me, because "bad screens" typically have a huge impact on my eye movement ability, but I am so happy to report that it is the opposite and almost therapeutic.
I tried desktop versions of websites with lots of tiny links, and even tried navigating around a complex web app (the web version of Visual Studio Code). Shockingly, I was totally able to click the right thing 90% of the time just by moving my eyes.
Because you have to move and focus your eyes correctly to even be able to click the thing you want, if you are using it and successfully navigating around, that was possible because your eyes did the right thing.
This means every time you interact with a UI element on the Vision Pro, it is literally training your eyes how to move better, and more in sync with your intentions.
I think this control method is THE reason why I had such a surprisingly comfortable Vision Pro experience, despite the use of PWM and (possibly) dithering.
You can also select letters on the virtual keyboard with just your eyes, which actually felt like a cool way to "exercise" darting my eyes around to precise locations. (I thought typing with my eyes like this would make me dizzy, but it surprisingly didn't!)
I actually came out feeling like I could control my eyes in the real world better, which is a really good sign that my theory that the Vision Pro might help "train my eyes" might actually be accurate. This is in contrast to typical "bad screens", which usually even make reality look worse for a few hours after using them.
I came out of the Vision Pro feeling pretty great with only some slight strain.
Of course, a custom "0 PWM, 0 FRC, 0 Dither" laptop or desktop setup definitely can still be more comfortable in the end and can offer wayyy more sharpness and clarity…
But the Vision Pro actually outclassed many "typical, unmodified modern displays" for me in comfort (including the rest of Apple's current lineup, LOL), which is awesome and something I didn't expect at all.
Just don't use the Mindfulness app! (or any other app that similarly blacks out the background)
