These are studies in how people perceive the world differently due to unique combinations of biology, culture, memory, and personal experience, meaning no two individuals see the exact same reality. While the eyes take in data, the brain interprets it based on past experiences, biases, and structural differences in the visual cortex. Many different perspectives such as contextual lenses and professional perspectives are differences that highlight perception as an active, constructive or destructive process rather than a passive, accurate recording of reality. This means all of the viewers of this art will see things differently.
