Not everyone wants to make a dark room brighter. For programmers, darkness is often intentional. It creates a focused environment where distractions fade away, especially during late-night coding sessions.
But when the monitor becomes the only bright light source, the strong contrast with the surrounding darkness can increase visual discomfort. The challenge is therefore not to fully illuminate the room, but to add enough light to make the workspace more balanced without disrupting focus.
This is where bias lighting comes in. By softly illuminating the wall behind the monitor, it reduces the brightness difference between the screen and its surroundings without lighting up the entire room.
