In the novel "Jesus' Son" by Denis Johnson, the author conveys a vivid and striking image of a character through the peculiar description of his eyes. The comparison to joke shop items suggests a sense of artificiality and absurdity, highlighting the character's oddity and perhaps his detachment from reality. This expression captures the quirky and sometimes surreal nature of the storytelling in the book, which is known for its raw portrayal of life, addiction, and human experiences.

The choice of words emphasizes the unconventional and possibly unsettling aspects of the character, inviting readers to consider the deeper significance behind such a whimsical comparison. It serves to establish a tone that is both darkly humorous and poignant, characteristic of Johnson's writing style. As the protagonist navigates through a world filled with chaos, this imagery enhances the narrative's exploration of identity and existential struggles.
