Yup, but let's be realistic: True 3D vision (i.e., what you see in real life, not movies) works because your two eyes see (slightly) different things. If you were blind in one eye, not only can you not appreciate 3D television, but you also don't get the same kind of depth-perception that folks with two eyes get. So while a passive approach may make some things feel like they have more depth, until we have projective holography, it will require some means of ensuring that your two eyes are seeing different images to have television more closely resemble real-life three-dimensional vision. (And even with holography, they still would be limited in the depth-perception that they can project by the distance between your eyes and the projector, modified by the scale - so even if they're projecting a 100:1 scale, i.e., very tiny, they could still only depict something perhaps three football fields away.)
