If you're asking this because you've noticed something weird with your eyes, things are blurry, or they hurt, go to the opticians. They're best placed to tell you what to do. Otherwise, I use a couple of lamps to up the ambient light if the light in the room is otherwise too dim. Eye drops can also be helpful if you're using a screen for exceptionally long periods per day.
