Smallish single-eye piece (or Boba Fett-like armature) that tells you at a glance hot much infrared radiation a surface is emitting.

Useful in the kitchen or on bounty hunts.

monocular night vision http://www.buythewo...ghtvision/monoc.htm
Probably not quite as small as you'd like, but pretty close... [egnor, Jul 19 2000, last modified Oct 21 2004]

the IR used in night vision goggles and heat IR are slightly different frequencies. what you are looking for is a pyroelectric sensor that can be sonar(or otherwise) tuned for distance to the object being viewed. these exist(industrial and medical apps) but i'm not sure about in monacle form.
