Take a break. Every half hour/hour, look away from your computer. Look at something at a distance. Outside a window. For a few minutes. 5/10 minutes.

If you can, reduce screen time. No more than 3-4 hours a day. If you can't, take a computer free day every 2-3 days.

This has helped me more than any setting, or app.

I think this is unfeasible for a gigantic portion of this site readership.
