Wien’s Law falls short

According to Wien’s Law, the energy we receive from the Sun peaks in intensity at 555 nanometers (nm), while under low-light conditions, scotopic vision reaches its maximum sensitivity at 508 nm. However, a study conducted a few years ago with the participation of Spain’s National Research Council (CSIC) proposes a new theory. It suggests that this phenomenon doesn’t depend solely on energy; the entropy of the radiation—a thermodynamic quantity tied to the amount of information we can perceive from our surroundings—must also be considered as a variable.
 
Since not all wavelengths (or colors) carry the same amount of information, human vision has adapted to prioritize those that provide the most insight. In other words, the human eye focuses on what delivers the greatest understanding of its environment.
 
Put simply: We see what matters to us. And this principle holds true across every aspect of our lives.
