I don't know that I have seen through the acromatics before.  I have a
Keystone "stereobinocular" that came with a Tour of the World card set, would
that have them?  When I say the plastic ones work fine for me, I mean that
they allow me to see my stereocards without double vision or excessive strain
and my friends can use them without difficulty.

I also have a red button realist viewer, would that have achromats?
