How can I change the brightness of my computer screen?

My screen has no button to change the brightness of it. I am writing a novel for national novel writing month and it's beginning to hurt my eyes after long periods of time- is there a way I can change the screen brightness so that I don't completely destroy my eyes? It is starting to give my a headache :(How can I change the brightness of my computer screen?
What computer are you using, and what Operating System (XP, Vista for example)?
