I would like to see some studies about how long close screen usage impacts medium - long distance vision as I suspect there is a problem particularly with kids use of phones.

VR headsets like the #AppleVisionPro are going to massively increase the time our eye spend in that position.

Yes it is amazing when you first see a screen floating in front of your eyes and you can interact with it even though it’s not there, but let’s not forget that our eyes are so important to us as it’s probably the most important way in which we experience the world and to damage them for the sake of entertainment is and should be a big concern for humanity.
