ahem, speaking as a guy in his 40's who already wears reading glasses, they're fine. I've got the V1 (couldn't find a V2 stockist for the UK) and they come with 3 different fresnel lenses which you put between the screen and your nose and can slide backwards and forwards for focus/magnification. I can get a clean focus on the screen even though it's only inches away, without my glasses.
In that case the quantum goggles may be better than some other nicer ones like the headplays simply because of their lens' distance is adjustable
