I recently found out that flux can change the monitor light to (or mimic) incandescent light. It give me noticeable improvement on my desktops with BenQ monitors. I tried flux before, but never felt any difference. Not sure what changes were made in flux, this is the first time it helped me. I always thought wearing a blulight blocker clip-on works the same as software reducing blue light. Now flux makes me wonder that is probably not true. A software is able to fundamentally change the way the monitor emit lights whereas sunglass or monitor filter is not.
