I don't know why but low contrast, dark themes strain my eyes more than their counter part.

Wondering if it's because I have astigmatisms in both eyes - I'm sure I've read somewhere that's the case but cannot remember where.

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've found a layman's piece but there's more academic material too:

Also mentions that despite 20/20 vision from LASIK, contrast sensitivity may not return.

I don't think we are alone :)

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