I've got Lazy Eye . . . And I can't see proper.
-- Joe (I)

Importance: When Joe first meets Treacle Walker, Treacle Walker expresses curiosity over his eye patch and thus the condition of his eye. In this scene, Joe attempts to explain the condition in the most clinical way that he can. The moment introduces the reader to Joe's distinct way of seeing. However, as the narrative unfolds, Joe's supposedly defective eyesight will gain in symbolic significance. Indeed, Treacle Walker will particularly encourage Joe not to think of his eyes as dysfunctional. He rather notes that Joe's eyes allow him to see the world in a more transcendent and distinct manner. In the latter sections of the novel, the ways in which the characters will describe Joe's eyes will live in sharp contrast to the above moment. The line is pertinent to understanding the author's explorations regarding sight and perception.

Every why has its wherefore...
