I have one on the left eye but preferred white on black before I switched to Windows (from Linux), where the system colors are black on white and thus I have mostly windows with black on white open (a few dark terminal windows are extremely distracting).
On the other hand, I found white/colored text on blue (as modern in the 90's, e.g. Turbo Pascal and other DOS editors/IDEs) quite readable.
