Simply make text bigger . 125% DPI or 125% "zoom" depending on the OS/application help with eye strain massively, and it surprises me how few colleagues are willing to try it (e.g. "I can see perfectly, why would I increase text size?!"). Between that and lowering a monitor's brightness to below 50% (often around 35% depending on brand), are my biggest tips. Windows now has a blue light filter built right in (Setting…

Great point. I read HN at 160% zoom on FF.

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.

...80%, personally. Even 100 looks comical on most sites, I can't imagine using 160%.

But I think this is too dependent on monitor, system font, etc. to generalise.

I've invested in using eink monitors from Dasung. I use one in landscape and the other in portrait mode. I experience no eyestrain after making this switch, using a computer for 8+ hours a day. My daily driver runs NixOS, i3wm as my window manager, and I've changed the editor and themes of my most commonly used applications to work with the monitors. I recommend the investment. https://dasung-tech.myshopify.com/produ…

How fast is the 'worlds fastest', can you actually use these for typing (with your eyes open)?

1) Don't sit too close to your monitor(s). They should be as far away as they are big, so if it's a 23" monitor, at least 23" away from your eyes. 2) Place the top of the monitor at eye level 3) THE BIGGEST: The 20/20/20 rule. Every 20 minutes, look at an object 20 feet (6m) for 20 seconds. These three changed my computing life forever, and for the better, especially since I'm on a computer 10 hours a day most days.…

You can also use reading glasses if you're perpetually too close.

If you work in GUIs a lot, your menus and stuff are at the top of the screen, and you can keep the top of the monitor eye level. If you're a programmer and you use a fullscreen terminal, with the line you type on the bottom, your monitor needs to be higher.

Guake is a nice approach too: a drop down terminal that puts your current line in the middle, at normal eye height. Configurable of course

I made two changes.

1) My regular prescription glasses now have a blue blocking coating. It gives them a slight yellow tint that I don’t notice, and it noticeably reduces eye strain (but does not eliminate).

2) Bias lighting behind my monitor that lights up the wall behind it. Staring at a bright screen in front of a black wall is no bueno, bias lighting at least alleviates the contrast between the two.

For #2, get a monitor arm that lets you readjust the height of the monitor, especially if you regularly alternate between sitting and standing. The mono price one is good value for money here.
