  I assume people without stereo vision still
see stereo effects due to motion parallax. Even
we 3d-ers see it in 2d movies. The Arnie movie
True Lies (?) where they pan the camera around the
Harrier jumpjet hovering beside the crane is very
effective even without 3d images on the screen.

  People not used to wearing glasses may get
a headache from the pressure on their nose,
temples, or ears.

  Another possibility is that the fellow wasn't
holding his head perfectly vertical and thus had
problems with ghosting.
