Good monitor for reading?

Some led monitors hurt my eyes after extended use. And i'm a programming student. So i spend quite a while working on it. My current tn gaming monitor is uncomfortable when reading. So what specs should i be looking for? Any models recommendations?

Added (1). p.s. I like my ipad screen for reading very much (but can't use it for programming) and for monitors i hate think of f.e. Lenovo g500 monitor.

There are apps browser extensions and probably settings you can change to turn the white background into a sort of gray color so it should be less harsh on your eyes.

That usually indicates you need glasses. Get an eye test.
