Psychedelic posters in the 1960's were de riguer.  These cool glasses bring those posters to mind.  These glasses come in red, black or white.  The frames feature a domed lens with spiral design.  Center of lens is clear so you can see through them.  Great costume piece for Willy Wonka , mad scientist or a hypnotist!   Reminiscent of the X-ray glasses sold in the back of comic books.  Makes a fun gag gift or stocking stuffer.
