Based on Robert's posts, I'm thinking it's a home grown mid index lens,
cast with a little extra pigment so they don't look too wierd indoors.  
They are new, in one of the Wiley X gasket/military styles.  I'm not
going to let Wiley make the lenses, because they charge retail prices to
eyecare people, way more than my own optical lab would.  I'm going to
put them in total dark tonight and see what happens.  The patient kind
of liked how they look.  Unfortunately I can't add any tint to a
Transitions lens.  So I might go for one of the Colormatics or whatever
and add some tint?
