I would like to know if there is any recommendations about how far from the computer screen it is good (healthy) to sit when I work in front of the computer long days. In an ergonomic perspective.

This page which turned up on a search for "ideal distance from computer monitor" states:

viewing distance - the monitor should be at a comfortable horizontal distance for viewing, which usually is around an arms length (sit back in your chair and raise your arm and your fingers should touch the screen). At this distance you should be able to see the viewing area of the monitor without making head movements. If text looks too small then either use a larger font or magnify the screen image in the software rather than sitting closer to the monitor.

Which isn't definitive, but does raise the good point about adjusting the screen resolution and/or font sizes rather than moving closer to (or further from) the screen.

I've asked the same question before. It appears the "one arm rule" to be in place. However I tend to disagree for larger displays like 20+". Wikipedia also has a nice article about calculating viewing angles, distances and field of view.

And my own adapted rule for screens above 14" is: distance = 1.5 * screen diagonal.

Here's a nice visual representation of guidelines: enter image description here

This seems to agree with some of the other answers here, but some people find a visual easier to grok.

It depends on the eye sight of the person. Some feel comfort sitting closer to the screen. While for some it will be to sit far.

But in normal case (with small monitor) a minimum of one arm distance (30 cm) is to be between our eyes and the monitor.

(The distance should increase as the height of the monitor increase)

I think that is is best to sit pretty close to the computer, i sit about 10-15cm away from the monitor otherwise my eyes get pretty sore, and everything is blury. My eyesight is so-so, but hasnt got worse in a few years. Most of my friends sit like this too, seems to be the best distance on a 17" screen. I usually go back about 1cm for each inch bigger
