I made two changes. 1) My regular prescription glasses now have a blue blocking coating. It gives them a slight yellow tint that I don’t notice, and it noticeably reduces eye strain (but does not eliminate). 2) Bias lighting behind my monitor that lights up the wall behind it. Staring at a bright screen in front of a black wall is no bueno, bias lighting at least alleviates the contrast between the two.
