Final answer:
The mention of Ray-Bans in Miguel's statement metaphorically refers to a change in perception accompanying the character's transformation. It signifies a movement from ignorance to knowledge and reflects a common literary theme of enlightenment or disillusionment.
Step-by-step explanation:
In the last sentence where Miguel mentions that he "also lost the Ray-Ban which had barred my eyes from seeing," this reference to vision can be understood metaphorically to represent a change in the character's perspective or awareness. Throughout various stories, characters often undergo transformations where their literal or metaphorical vision changes, signifying an awakening or a loss of innocence. The Ray-Bans could symbolize a barrier to a true understanding of his situation or the reality of his life. With their loss, it may suggest that the character has gained a new perception, acknowledging something previously ignored or unseen. This transformation can be viewed as a move from ignorance to knowledge, mirroring classic themes of enlightenment or disillusionment found in literature.
Considering the passages provided, this theme of change in perception is recurrent. Characters may come to recognize their disillusionment, having lost what they once had, as suggested by the descriptions of the environment and personal appearances that reflect inner states of being. Whether this recognition results in a character becoming wiser or falling into despair, it is a pivotal moment that determines the path their future will take. The loss of the Ray-Bans alongside Miguel's transformation indicates a poignant moment of clarity, that can be both liberating and harrowing.
