If it's so obvious, how come nobody else does it?

Also, to be clear, I doubt they're getting a patent on "changing your video card's CLUT (color look-up table) to reduce eye strain" but rather on the specific method they use for doing so.

How else would you reduce the amount of blue light emitted by a monitor using a CLUT except by changing it to reduce the amount of blue light emitted?
