One thing I've considered is that many could have be having eye strain from using excessive resolutions and then straining to see what is on the screen and/or having to have the bright screen too close to their eyes in order to see it clearly.
What about running a low resolution on a big screen and pushing it far away from the head?
As said before, I used to run 800 x 600 on a high-end 19" CRT, and it was very comfortable. No strain at all.
Here's a 32" that is only 1080p. Thoughts on something like this for alleviating strain?

One of the pleasant things about this unit is that you can get it for only US$200.00.
It seems like a bargain.
I've been using my screens further away with some scaling and my browsers zoomed, and it does seem to help. It also makes basic sense why it would since the backlight is further away from my eyes yet the screen contents are enlarged so I'm not straining to see the material.
This 32" 1080p would allow me to use it natively without zooming things and I'd be able to sit a good distance away.
Back when I used the 19" CRT I was told to sit a few feet away from the screen to protect my eyes, so that's what I did, and that's why I used just 800 x 600, which was very comfortable. Going higher than that, like most people did/do, definitely strained my eyes.
Now I read this: "Regarding eye strain, the most common cause of this is setting the monitor backlight too high. Especially with LED backlights. Even in a normal lit room I only have set the backlight to around 10%. You may need to get adjusted to this first if you are used to normal settings (e.g. the default settings of the monitor which are always way too high), but for me it helped great deal with eye strain and headaches."
I think this is poorly thought out actually. If the light is too low it will feel better initially because the eyes aren't being hurt by the excessive light, but they're going to struggle over time same as you would trying to read books with insufficient lighting.
The problem probably goes back to people using their devices too close to their eyes, and they have to do that because resolutions have the pixels crammed together too tightly for them to see properly when the devices are a good distance away.
Therefore, it makes a lot of sense to buy a bigger screen with an "undersized" resolution. The 1080p of this 32" is commonly found on 22" and 24" units. On those it's too much, and on this 32" it should be perfect for ideal long-term comfort. The screen can be much further away from the head.
