It depends a bit on what type of eye strain you’re experiencing.

Dry eye typically comes from not blinking enough. It can also be worsened by blepharaitis (inflammation of the eyelids).

If you feel like you’re straining to focus (and you haven’t already), you should see an optometrist and get computer glasses.

I have a pair that I wear occasionally, and I find them especially helpful with low-res (e.g. medium to large 1080p) displays. On that note consider getting a 4K or better display, especially if it’s larger than 20” or so.

Finally there’s the so-called 20-20-20 rule, which is to focus on something at least 20 feet (6m) away for at least 20 seconds at least once every 20 minutes.
