There's absolutely nothing wrong with saying something like "there are now several projects/products that aim to alleviate this problem, such as ProjectA and ProjectB." Also f.lux is freeware.

These apps are also a lot more feature rich than twiddling with display settings - you can customize their aggressiveness, set times, set timed breaks for color-sensitive work, sync to the sunset in your location, etc. You could do this all manually but I doubt anyone actually would.
