Green Lantern #16 (2007)

Harry Danvers is a carnie, born with only one eye. A lunar eclipse causes him to go wild with rage and steal a blade from the sword-swallower. Fortunately, Alan Scott and Doiby Dickles are attending the show and step in, but the eclipse also makes Green Lantern's ring go crazy with power, and propel all three to the Moon. There, they're attacked by an army of misshapen monsters. Because GL refuses to fight with his ring while it's shorting out, and the monsters somehow have wooden clubs that get through the ring's protective powers, he and Doiby are overwhelmed. The duo are tied up and taken before the monsters' leader, a giant chicken with three heads. It calls them "Selenites" and says they must be killed. Before the deed can be done, a female monster becomes smitten with Doiby and cuts them free.

The heroes flee into the underground tunnels, and soon discover a chamber filled with one-eyed men. Expecting more monsters, GL and Doiby attack, only to find out these are the Selenites, the scientifically-advanced rulers of the moon. The Selenites put the savage monsters on a reservation to keep them from killing and destroying. The same Selenites also found Harry Danvers and offered him shelter. The eclipse starts fading, and Danvers leads GL and Doiby back to the surface, so they'll be pulled back to Earth when the eclipse's effects end. Danvers himself decides to stay on the moon, where he'll be considered normal among the other one-eyed men. GL and Doiby make their return in the middle of the high-diving stunt at the circus.
