Unfortunately, unlike the rest of you (seemingly), I can read just fine. i just can't see distance!
I guess I should've elaborated; my bad. In my case I am near-sighted, and I bought the reading glasses so I could have my normal prescription installed in them, not to read with them. The trick is that many optometrists won't install prescription lenses into reading frames unless they're "optical" quality. I don't know what the threshold is for that quality, but $70 seems to be the starting price where you start seeing it listed as a selling point.
I also have a pair of those goggle inserts you talk about. They're flat and easy to stash, but I'm not too crazy about them... the straps seem fragile, and the lenses are so big that they distort differently than my small everyday glasses, even though they correct to 20/20. I think I'm just not used to having a lens that far towards the edge of my vision.
