I, too, am older with older vision.
Before going further, let me say that at my age, I find
the size of text, rather than the "sharpness" of text, is more important
to make it readable to me.
To put it another way, it doesn't matter how sharp text may be (retina or not) -- if it's too small, I can't make it out!
I use a 27" 1080p display that has a pixel size of about .31mm (1920x1080).
Most of the younger folk here start shrieking when I mention that, saying "a display like that is too GRAINY!".
Perhaps it is
for them.
But NOT for my old eyes.
I'm wondering if this is the case for you.
If you go to a 1440p display, which is 2560x1440, you need to take into account the overall size of the display.
At 27", the pixel size will drop to .23mm.
This is getting to be "too small" for me, retina or not.
The Apple 5k iMac (with a retina display) yields 2560x1440 at 27". I find that text displayed "at normal font sizes" to be "too small" for comfort. At least for me.
I helped a friend set up a 2017 5k iMac, and he, too, didn't like the small text. He ended up decreasing the displayed resolution to make everything larger, so that he could read it.
BUT...
Increase the display's diagonal size to 32", and 1440p results in a pixel size of .277.
For me, that's tolerable and usable.
BE AWARE that there are few (none?) 32" 5k displays. If any exist, they are bound to be quite expensive.
HOWEVER... there are numerous 32" 1440p (native resolution) displays available.
This might be "the best compromise" for someone with older vision, who wants a larger display but one that still yields a pixel size "easy for older eyes".
Here's a very useful URL for checking different resolutions and resulting pixel sizes:
