The answer is that your eyes would be focusing not at the concrete distance where the mechanism is placed, but at a virtual image which appears farther away.

This is just basic optics.

It is (one aspect of) what happens when you use a magnifying glass, for instance.

The virtual image of some point viewed through an optical instrument is that location in space to which the rays of light which are coming from that point appear to converge to.

So in the case of the magnifying glass, it assists our vision in two ways. Not only does the image appear larger than the original object, it is also farther away, so that our eyes can focus on it. Glasses for correction of far-sightedness are magnifying lenses, yet their job isn't to make the world bigger, but rather to enable closer focus.

A screen that is placed very close to the eye simply has to contain the right optics so that a focused virtual image ends up on the retina. This will be done by somehow ensuring that the light rays emanating from the screen diverge at a sufficiently acute angle that they appear to come from a point that is much farther away than the screen really is: far enough away so that the eye can comfortably focus on that distance.
