Maybe we won't be using biological eyes any more. Maybe we'll be interfacing at the retina or neural level. If it's not any time soon, it may not be using any simple solution we can think of right now.
(In Oliver Stone's 1993 miniseries Wild Palms, the near-future AR/VR experiences are sometimes enhanced via a hallucinogen/hypnotic called mimezine.)
A cybernetic implant or augment could produce the effect of having another set of eyes that was seeing something else entirely.
Even cybernetic eyes that had a uniformly high-density perception area, instead of what's actually concentrated in a relatively small zone in biological eyes, might have the advantage of situating things "off to the side" but not requiring you to actually look at them to make sense of what's being conveyed.
