I have a pair of Gen-1 goggles ($500 US) and they will focus down to about 12-in (30cm). They have a build-in IR source (necessary in a totally dark darkroom), but this source emits a tiny amount of visible light in the red (very faint). If you get a pair of goggles, I would use a separate IR source such as this: http://www.maxmax.com/aXNiteFlashlight.htm I used the goggles for a while to aid in loading sheet film but got better at loading and can load in total darkness without them, now.
