I don't know about Viture, but the XReals come with a prescription lens attachment clip. I've got a set. It would be unusable without it, but even then the screen is only really great towards the middle of the field.

In theory the hardware has a motion tracker that lets you freeze the screen in space and pan around it by moving your head, which would be a huge win, but the current iteration needs an external dongle to do that which I don't have.

I'm going to upgrade to the next version purely because that's going to be built in (along with some other niceties).

This Steam Brick is right up my alley, although I'm wondering if you could do something just as slick with Framework guts. I haven't fired up Steam in a while.
