Various publications tout low intensity, medium/low-contrast as a tool to reduce eyestrain. IMHO, default font size, line spacing and column width are more important than high contrast (somewhat of a problem on this site too) Thought: should we aim to vary contrast by device? On my mobile phone I prefer sites with higher contrast, especially when out and about, on my retina iPad however, sites with white backgrounds and lots of text are much more tiring/difficult to process (plus bright screens, incl. tablets and phones are shown to result in insomnia [1]). At the risk of going completely O/T here, f.lux [2] has helped me a lot in this respect.
