Just to provide a bit of a more serious answer in case you weren't joking, you don't need to "protect the programmers from the display". It isn't the light/radiation/whatever from their monitors that's resulting in them looking pale, but a simple lack of sunlight. A project, oled monitor, etc. will also make no difference what-so-ever.
It's commonly recommended to take regular short breaks from programming -- even if you stay inside -- to avoid problems such as cramping, carpel tunnel, DVT, eye-strain (this is a real problem that can be caused by staring at monitors too long!), etc. To stay at your peak productivity whilst maintaining good health you should ensure you're drinking enough water, have a reasonably healthy diet, and get some exercise each day. You should also make sure your work area is set up correctly to avoid straining.
