The day I can put on a pair of AR glasses as lightweight as my current glasses and gain better vision, I'd pay a huge amount for that.

I hate my varifocals because of how constrained they make my vision feel...

And my vision is good enough that the only thing I struggle with without glasses is reading.

To me, that'd be a no-brainer killer app where all of the extra AR possibilities would be just icing.

Once you get something like enough and high resolution enough, you open up entirely different types of applications like that which will widen the appeal massively, and I think that is what will then sell other AR/VR capability. I'm not interested enough to buy AR glasses for the sake of AR alone, but if I could ditch my regular glasses (without looking like an idiot), then I'm pretty sure I'd gradually explore what other possibilities it'd add.
