Spectral Distribution Glasses

I'm cleaning out some old piles of paper in my office and
came across a pair of spectral distribution glasses that
Philips gave out at a Light Fair or IES meeting, probably
around 2000, based on the "layer" in which they were found.

These look like 3-D glasses, but resolve the SPD of any
light source the wearer looks at. Rather neat, if you can
find a pair.
