No doubt that he sees the world in 2D, but if one eye is only good for 
distances, how would that eye focus on the slide in the viewer?

When I got to the age where bifocals seemed to be inevitable, my 
ophthalmologist suggested correcting one eye for close-up and the other eye 
for distance using contact lenses (I don't wear spectacles because my ears 
aren't even remotely the same height).   I asked how this would affect my 
ability to see in stereo, and he replied that my depth perception would 
probably be toast.
