A permanent discoloration of areas on an electronic display such as a cathode ray tube (CRT) display or computer display monitor or television set caused by cumulative non-uniform usage of the pixels.

Screen Savers are designed to fight of screen burn.

My security camera monitor is screen burned in so much that I can see it even when not powered on.

The irritating feeling of the skin caused by long exposure to the rays of the computer screen especially in the dark room or at night.

Screenburn is actually caused by the eyes seeing screen too long but the brain mistakenly feel the pain on the face area causing screenburn effect.

I'm having a bad screenburn after working 6 hours straight at night. Now I need to cool my face down.

The condition people have where they have a hard time focusing their attention, maintaining a face to face conversation, and being alert due to being in front of screens for too long.

Lenny: Hey! Finn! I'm talking to you! What the hell is your problem?!?
Finn: Nothing. I've been listening to you.
Lenny: You're driving!! Remember?!?!
Finn: My bad. I'm screenburnt from staying up late last night and early this morning.
