Ron, we are now thrust into (or, in truth, have been living in) the realm
of optometry (the 'measurement of vision').

Here are some accepted optometrical terms for one-eyed vision: monocular,
monoscopic.  Also, there are monocular cues for depth.  They include: Scale
(as when a large image perceived adjacent to a small image is interpreted
by the brain as nearer), Occlusion, or Overlapping Contours (edge lines of
the nearer object overlap the farther object), Atmosphere (objects seen at
a greater distance tend to get softer and hazier) also known as Diminution
of Tone.

All of these monocular depth cues reinforce the 3-D effect in a
stereoscopic image perceived with two eyes.  Stereoscopic (meaning 'solid
seeing') is not truly a definitive way to convey the concept of an object
perceived with two eyes (and as a result, with parallax, i.e. the
perception of an object or scene from two slightly different points of view
simultaneously).

So, to be precise, we might term 'one-eyed 3-D' as "monocular stereopsis"
and two-eyed 3-D as "binocular stereopsis."
