I understand your perspective on night vision being related to psychology. However, night vision involves both biological and psychological aspects. Biologically, night vision relies on the function of the eyes, specifically the rod cells in the retina that detect low light levels. This physiological process is a key part of biology. On the other hand, how we perceive and interpret what we see in low light conditions involves cognitive processes, which is where psychology comes in. So, while the biological mechanisms are crucial for night vision, the way we experience and understand it also involves psychological factors.
