If you get your eyes adjusted for seeing in the dark - people who do this - sailors, astronomers, pilots - so that your eyes can actually catch the faint light of True Night, you want to keep them that way. Red light doesn't trigger your eyes into thinking the sun is up and should switch to Bright Light Vision. So for them it is Real Nifty. For the rest of us - ever get blinded by that weak little light bulb after you got your eyes all comfy in the dark? Yeah, this Red Light Reader will prevent that too. Your roommate will thank you. Me? I got myself a Red Light Flashlight years ago at my astronomy shop. Not as fancy, but the result is pretty much the same. Actually, Red Light is used because it doesn’t ruin dark adapted eyes.
