Ntrudr may need a different prescription for optimal vision but my guess is the reading glasses will work.
Reading glasses will not improve it, in fact quite the opposite if you have myopia (short-sightedness) which is the inability to focus on distant objects. The fresnel lenses built into the Oculus headset have a correction that allows people with good eyesight to appear as if they are viewing an object at a distance when it is only an inch or so from their eyes. The only other place (apart from the site quoted above) that I know does prescription lenses for the Oculus and the Vive are vr-lens-lab.com. It is worth visiting their website for a good explanation of how both the Oculus and their lenses work technically. My husband has a pair of those lenses which work perfectly, and I have a pair on order which coincidentally should be arriving today.
My husband advises NOT to wear ordinary spectacles inside the headset. The lenses on his first Oculus became scratched due to contact with the glasses; fortunately, that Oculus had a fault (fortunate for him) and the whole headset was replaced, which was one way to get rid of the scratches - lesson learned.
