I've been playing around with the smallest width settings again in developer mode. If I set this between 475 - 500, the text and icons/images all shrink, but also become a lot more clearer and comfy.
I've tried this on a number of lcd phones, and it seems to be helping me further. Might not work for everyone, especially if you have hyperopia. But it's worth a try.
I always assumed smaller text/icons would cause more strain. This doesn't' seem to be the case with me, surprisingly.
