Basically, these are normal binoculars:

All good. The question is how would these feel:

A theory is that they could make the world feel closer to your eyes, or (what is the same) smaller.

If normal binoculars are just extended, then you could only see stuff really far away (You have to be able to see the object with both lenses at the same time and since normal binoculars have a small field of view, this would require the object to be really far away). Those objects would feel closer because you would be able feel the parallax effect that helps determine the distance of close objects, although it would be heavily distorted (that’s why they would feel closer).

If, on the other hand, special binoculars with not much magnifying power but great field of view where used, then maybe you could achieve a feeling that your head is bigger than it is, maybe you could even make it so you feel that your head is the size of a room.

Expected feeling:

This idea can be explored in VR simulating the binoculars in unity with cameras and shaders.
