Red light or led is good for eyes?

I recently read that looking at red light is good for eyesight. Does anybody know what sort of red light I should use? I have red LEDs but I thought that was bad for eyesight. Am I supposed to cover a flashlight with red paper and look at it? I've searched for what type of red light I'm supposed to look at... No avail.
