It wasn’t all that long ago that there were these screens on a lot of computers.
People bought them by the doves to stop them from getting head cancer and to stop them going blind.

“Tetrachromacy is demonstrated among several species of birds, fish, amphibians, reptiles, insects and some mammals. It was the normal condition of most mammals in the past; a genetic change made the majority of species of this class eventually lose two of their four cones.”
