From my limited experience with a Quest 2, yes, the images should be stable. It had a focus wheel. I don’t wear glasses and don’t know what is missing, but I borrowed it from someone that does wear glasses and he never complained. They are not traditional glasses lenses, they are fresnel lenses - the ridgy kind you might see on lighthouse beacons. Where as curved glasses lenses typically have a single curve to them and have limits to how close the object can be before misalignment of the image due to the curved nature of view, fresnel lenses have a flat outer surface and, in this case, are viewing a flat image panel. The only variable is where the convergence point sits in your eye. For standard near/far sightedness, this should be sufficient
