Super fun, and just in time for Halloween, this is a c. 1950s pair of glasses with "Vari-Vue" lenticular lenses. Both eyes change from wide eyed blue (a little bloodshot around the edges) to closed, depending on the angle, but are always opposite from one another, i.e. always winking. Sight holes at the center of the lenses make them wearable, and for someone like me who is not very good at winking, pretty handy, too! 

Very good condition. Glasses-sized! 5" across. Stems are 5 3/8" long when open.
