Hey Karl,

Called a "reflex lens". A company in Windsor, Ontario, ITL Reflex
Division, was a forerunner in mold production of these for many years.

I do know that the injection mold used to make an automotive lens is
VERY VERY highly polished on the "visible side", while the inside is
not so much. I don't know how you would achieve that same polished
surface any other way. Maybe someone from the "art world" would know
about that part.

Take care.
