Four Eyes and Six-Guns.

Ernest Albright opens his eyeglass store in what he thinks is a thriving community, but soon discovers that his store is just a shabby shack in Tombstone, Arizona. The town's Doom Brothers are trouble for everybody including Wyatt Earp, the sheriff. Ernest uses his own special brand of short-sighted shooting to help Wyatt rid the town of its worst citizens and live in peace.
