I've never heard of this actually, I would have thought black on white was the best way to read text.

What would be a better choice? Would black on off-white be better?

While most printed materials are "black" on "white," when the range is compared to a light-emitting screen that's more like "dark gray" on "light gray." Looking at something with too much contrast for a long time can cause eyestrain.

Honestly on a backlutz screen, grey on navy is hard to beat. There's a reason all of those 80s mainframe apps looked like that. They did studies.
