UPDATE: I bought a circular polarizing lens and found that even with that lens, it still has a specific angle where it blocks light so I'm not sure what's going on. I thought for a circular polarizer, light output would be reduced evenly at all angles whereas linear polarizers block at a specific angle. I don't know enough about polarization to know for sure whether some of these panels are actually circularly polarized or linear, so I'm just going to include the darkness angle that I measured with my linear polarized glasses.
The AW2521H and PG259QN also have a heavier matte finish than the other matte panels.
There is one discovery I made which is many displays come with a slight green-leaning color temperature which may be easier on the eyes but I'm not sure of this yet. I recieved a version of my old Samsung TN to test, and I discovered it's notably more green in temperature than sRGB 6500k, and so was my BOE NV156FHM-N4B, and my Galaxy s10e. Also, color ghosting is worse on a 2022 Samsung G32A VA than the 2009 Samsung 2494 TN -_- Insane display tech has barely changed or improved for your baseline after more than ten years.
I'm still not 100% sure what all of the contributing factors are here for eye strain, but I do believe that polarization is a contributing factor. I do think my eyes don't like horizontal polarization, but some eyes may prefer it. The polarization study does show that circular is supposed to be the best however. A higher matte grain could also contribute to reduced focus on text. A screen taking up more % of your FOV also contributes. Brightness level also contributes and I believe high contrast scenarios can be bad at high brightness. And I really am going to pay attention to the slight green-color temperature that I've seen in so many displays but I do think color temperature does contribute.
