Short answer: Yes, there are plausible reasons to consider dark mode for CAD work. Dark mode can reduce glare and blue light exposure, which may ease eye fatigue during long sessions. However, it isn’t universally better—some users find dark interfaces harder to read or distinguish fine details. For SketchUp, the demand for dark mode is strong because many professionals report headaches and eye strain from its bright UI.
