Because it's not a 3D TV, it's just one that displays two different 
viewpoints.  Your eyes are hard-wired to adjust both focus and 
convergence simultaneously.  Since '3D' TVs only adjust the convergence, 
but not focus, you have to consciously work to keep focus constant, 
which causes strain and headaches.
