Same, the Thinkpad's crappy monitor is a great unintentional feature.

I used to have astigmatism in both eyes. After three rounds of laser I don't.

I throughout strongly prefer high contrast schemes -- indeed I don't like any syntax colouring at all.

I'd like to see that article if you can find it. I admit as a sample size of one I might be aberrant but if not, then the effect you describe (if it exists) might have a neurological basis as well.

I prefer medium to high contrast. If it gets too low, it gets hard to read.

When I am having trouble focusing on work, over the years I've found kicking everything into grayscale really helps me get more done. Since learning to code, though, I haven't found a good grayscale solution to syntax highlighting. This looks like it has just enough, thanks for sharing!

I also used it for quite some time. Switching back to Leuven now and then.
