In "Whores for Gloria," William T. Vollmann presents the idea that sunglasses create a barrier between the wearer and the outside world. They allow individuals to observe their surroundings while remaining shielded from external scrutiny. This protective layer creates a sense of safety and quietude, enabling a more introspective experience as the wearer feels isolated from the world around them.
Vollmann suggests that wearing sunglasses transforms perception by filtering reality, akin to viewing life through tinted glass. The use of mirror sunglasses intensifies this effect, suggesting an added level of defense against the chaos of the outside world. Overall, the imagery conveys a powerful metaphor for personal privacy and the emotional armor one wears to navigate life.
