I've found a layman's piece but there's more academic material too:
http://www.allaboutvision.com/eye-exam/contrast-sensitivity....
Also mentions that despite 20/20 vision from LASIK, contrast sensitivity may not return.
I don't think we are alone :)
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.
