If you find light painful it means the light is too bright. Changing the color of the light is a bandaid. In my experience people use screens which are way, way too bright, and also they use computers in the dark when they shouldn't. Use bias lighting behind your screen. (Of course there are use cases where you want full darkness, like watching movies.) In the evening on my mac I use 1/16 brightness, and when the room is completely dark my iPhone is set to minimum brightness. Set your screen brightness such that it matches a white piece of paper put next to it.
