For optimal viewing comfort and reduction of eye strain, it is recommended to sit about arm's length away from the screen. Adjust the distance based on your comfort level and the size of the screen.
A 70'' TV– You should sit between 9 and 14.5 feet away from the screen. A 75'' TV– You should sit between 9.5 and 15.5 feet away from the screen.
The computer screen should sit 18 to 22 inches from your face. And, the center of the screen should be about 10 to 15 degrees below your eyes.

there are many variables involved but it usually depends on the exposure time of the display to your eyes the distance you sit away from the screen and the type of display is in use i.e lcd led plasma or crt this applies to both your tv screen and computer screen
About 25 to 30 centimeters away.
It should be layed out so that when you sit in front of the desk the monitor should be elivated so top of the monitor's screen should be just above your eyebrows so your eyes get maximum view of the screen and on the the desk the keyboard should be on the desk in front of you placed at the length of where your arm are slightly bent and the monitor about 5cms behind the keyboard.

As far a way as possible but at a distance where you are still safely able to operate the vehicle
Because if you sit down to much on the "computer" chair you can get hormones or a headache or your eyes will start to suck
You really shouldn't sit all that closely, simply because it's hard on the eyes and besides, you need to sit far enough away that you can easily view the entire screen and not just a portion of it. As far as getting `too close', I don't think that x-ray's are much of a problem with the newer TV's and that was the only reason for having to sit at least 6' feet away from the TV in the late 50's before they learned to design an x-ray protection circuit.
