Behold the Monstrous Eyeball

While researching the monstrous eye and grotesque vision I came across the frightful creature depicted above.

In the Dungeons & Dragons role-playing games one of the classic monsters dating from 1975 is the Beholder.  

This violent and xenophobic aberration, aligned with lawful evil appears as a floating globule of flesh with a large mouth, a single central eye, and a variety of smaller, flexible eyestalks. These possess deadly magical powers.

In addition to observers and spectators, there are many variant Beholder species such as the gauth and the gouger,  eyes of the deep, elder orbs, hive mothers, the death kiss and the death tyrants.

I'm now searching/looking for other monstrous eyeballs. Next on my list is Les yeux sans visage (Eyes Without a Face) - a 1960 film directed by Georges Franju.
