I’ve worked in VR for a long time (including visionPro) and my eyesight definitely got worse. The most ironic thing to me is how iPhone has this screen distance warning telling you to move the screen further from your face while Vision Pro is literally an iPhone strapped to your face.
I was told the issue isn’t the physical distance of the screen to your eyes, but the distance of where your eyes are focusing? So in VR if you focus on an object a meter away it shouldn’t strain your eyes as much as a phone screen 10cm away? No idea if this is scientifically proven.
