How would it work? Where would you put the two lenses? Consider:

- You can't really have two lenses cemented together. That'll correct for chromatic aberration but, other than that, the lenses would behave as one (except for deviations from thin lens approx.)

- You can't have glasses mounting two lenses "d" apart for two reasons. 1) Having parallel lenses would terribly uncomfortable, heavy, and awkward 2) More importantly your eye and the two lenses would never be aligned (as soon as you move your focus away from the one spot the glasses were aligned for, the optical system performance would collapse)

- The best you could do, then, is contact lenses + eyeglasses. But then you have all the bother of wearing glasses and eyeglasses. Also, it's not obvious to me it would work since the contact lenses are in contact with your cornea, the pair behaving like a single lens.
