Ideal distance between head and monitor?

Hi everyone.
I know this is a crowded topic and everyone’s got an opinion, but I’d love to hear yours.
Hopefully, we haven't covered this already...

Basically, what’s the sweet spot for distance between your eyes and the screen (whether it's an old CRT or a modern LCD) to minimize eye strain?
Too close is bad, but too far isn't ideal either...

Thanks for the input. 🙏

Best, 👍

The distance from your elbow to your outstretched palm should serve as a guide. As for the monitor, one ought to position it slightly below eye level, though naturally tilted back to accommodate a more ergonomic viewing angle. Your feet should rest flat on the floor at a right angle, positioned parallel to one another, while your elbows remain aligned with the height of the keyboard.
