However, your eyes have depth of field view too. Your eyes are actually cameras in that point regard. Look at the monitor, your hand or any object close to you. Focus on it. Notice how the background gets blurry? That’s a feature from your eyes and brain to bring stuff into focus.
But besides this fact, even if you would see everything in focus, its does not mean the developers of film scenes (movies or games) shouldn’t use DOF as a tool for an artistic expression. It can help bring things in focus in a busy background.
Lenses flare and motion blur are some of the first setting I turn off in any game.
I hate DOF, too. Your eyes aren’t a camera, any place you look should be in focus!

Screenshake is similarly overused
Lens flare doesn’t bother me, but its “Depth of Field” that drives me bonkers. I always turn motion blur and depth of field off.
