Visual load shapes the day
Modern environments keep the eyes busy. Screens, signage, notifications, and movement compete for attention. Even when you do not notice each signal, your system still processes it. That ongoing load shows up as faster fatigue, lower patience, and a constant feeling of being slightly “on”.
In offices it can look like shallow focus and frequent task switching. In hotels it shows up as restlessness in spaces that are meant to feel calm. This is why I treat imagery as part of the function of a space, not decoration.
Biophilic design uses light, greenery, and natural materials to reduce stress. Imagery can do something similar, because it sits in the field of view for years. Good imagery gives the eyes a place to rest and helps the room feel less demanding.
