Coincidentally, i saw several headlines yesterday (now long gone from my news feed) claiming that blue light filters are not nearly as effective as once believed. It may be worth researching the current status on that info before committing to a red-only screen. (There's no way i'd buy one, in any case.)
The "pixels" of a screen are composed of red, green, and blue sub-pixels. Software filtering mostly reduces the blue and green light emitted, but does not eliminate it. And the sensors in our eyes, the rods, are less sensitive to red color, when compared to blue or green. This means that looking at a red-light only monitor would be closer to "night" vision.
