For reference I was already pretty used to gaming in VR on inferior headsets before working on the Vision Pro, so I might be more forgiving of issues than your average person.
I'd say that eye strain wasn't really an issue at all for me. When you take off the headset after a while inside of it you kinda get a jarring transition back to normal vision instead of passthrough, but passthrough doesn't have any noticeable issues when you're inside of it. It's almost like waking up from a dream where stuff feels different and you can't exactly place why.
As for physical weight, it's lighter than other VR headsets I'm used to but obviously more than a pair of ski goggles. I'll echo MKBHD's thoughts that the most noticeable strain was on my nose because my lightseal (like the WWDC demos) wasn't as personalized as the version you'd get as a customer, so I fully expect that to be a non-issue.
