Create holographic prisms on thin sheets of plastic. Layer the sheets such that the prisms refract light normally outside the human visual range to just within. Now objects which radiate infrared energy appear with a red halo and those which radiate ultraviolet appear with a blue halo.

As there may be the need for some energy transference (energy might be gained when pulling UV light 'down', and lost when pulling IR light 'up' to the visible spectrum) the glasses may require some additional electronics. The additional electronics would (of course) fit conveniently within the frame of the glasses.

       good... just so long as all the ordinary light isn't refracted...

       wow this is a cool idea

       correct me if I'm wrong, but prisms do not alter the frequency of light, but merely separate out the component frequencies of composite beams. So prisms wouldn't work. However, you may be able to selectively absorb and re-emit photons after altering their energy. Then you could use the energy gained from the UV to boost the IR, and come out even, on average.   

       The difficulty (which seems to not be insurmountable) is that the emitting and absorbing surfaces need to be transparent to visible light.
