Are you guys doing 4 hours straight?

A relative is an ophtalmologist and she told me that when working on a screen we should at least follow the basic 20rule of pausing every 20minutes to look and focus 20feet away for at least 20 seconds to avoid having dry eyes and eye strain. Even on a regular screen I am usually so focused in my task I don't do that unless I am interrupted by someone and/or set an alarm. I imagine it would be even more difficult with a Vision Pro as you'd have to unstrap the thing from your head.

I am no doctor, but as you said, you need to release the strain in your eyes by looking away. I suppose that is something you can do with this class of devices as each eye has their own screen. This said, I have never used any type of VR headset.
