Spending long hours coding, reviewing documentation, or monitoring dashboards can quietly lead to eye strain and reduced concentration, especially when screen brightness or glare isn’t ideal. That’s why using a black screen utility can be surprisingly effective in a developer’s daily routine. By switching to a plain dark display for short breaks, you can instantly reduce visual noise, give your eyes time to relax, and easily notice issues like uneven backlighting, reflections, or dust on the monitor. This simple habit not only helps maintain visual comfort during extended work sessions but also supports better focus and productivity when you return to writing or debugging code.
