Staring at a computer monitor or other electronic screen for extended periods of time may cause eye strain under certain conditions:

* '''The screen contrasts with the environment'''. The color temperature and brightness of the screen should be adjusted to match the surrounding environment. Or, the lighting in the room may need to be adjusted to better match the screen. Having the lights off in the room while staring at a screen is never a good idea.

Or, the lighting in the room may need to be adjusted to better match the screen. Having the lights off in the room while staring at a screen is never a good idea.

* '''The screen is too close to eyes'''. The screen should be at least an arm's length away from the eyes. With tiny phone screens, this is impractical; the bad habit of doing everything on the phone should be replaced with a good habit of doing as much as possible on a desktop or laptop computer at a healthy distance from the eyes. If you use a smartphone, consider replacing it with a feature phone.

* '''The staring is being done without reasonable breaks'''. At the very least, the eyes should be given a short break every 20 minutes and a long break every 60 minutes.
