I'm not sure that's en invention we need. ;)
I can think of a great many devices which are used for viewing stuff between several millimeters and a meter in size. Some, such as the overhead projector, are relatively obsolescent; others, such as reading glasses and various devices for putting a corrective lens in front of a person's eye, are in widespread use among the general populace and probably won't go away any time soon.
