There is a reason why most sight-impaired people, at least those I know, prefer light-on-dark. A bright background blurs out the foreground and makes reading hard. Dark-on-light only makes sense when switching between paper and screen frequently. To me, dark-on-light becomes increasingly hard to read as I grow older. So much so that I have disabled CSS in my browser entirely.

Like almost half the globe I have astigmatism: > People with astigmatism (aproximately 50% of the population) find it harder to read white text on black than black text on white. Part of this has to do with light levels: with a bright display (white background) the iris closes a bit more, decreasing the effect of the "deformed" lens; with a dark display (black background) the iris opens to receive more light and the deformation of the lens creates a much fuzzier focus at the eye. > Jason Harrison – Post Doctoral Fellow, Imager Lab Manager – Sensory Perception and Interaction Research Group, University of British Columbia > Jason Harrison – Post Doctoral Fellow, Imager Lab Manager – Sensory Perception and Interaction Research Group, University of British Columbia Borrowed from this answer in stackoverflow: https://graphicdesign.stackexchange.com/questions/15142/which-is-easier-on-the-eyes-dark-on-light-or-light-on-dark https://graphicdesign.stackexchange.com/questions/15142/whic...

  Looks like this study is about people with mild vision problems. As I said before, I know some people with more limited vision (myopia with more than 10 diopters, optical nerve damage, etc), and all of them prefer light letters on dark background. Myself I can hardly read on paper or a paper-white screen. Whatever science may say, this is how I experience it! :)
