I don't think this is just glare, since I notice the difference particularly 
in a dark room, e.g. without any light source for glare. It is much harder to 
focus your eyes on the letters alone, when the background is black. I don't 
know why, but on a late night session switching the background of the 
terminals to grey certainly relieves my eyes. I find this both on a CRT as 
well as on an TFT screen.

Although in the above case it may be too much contrast, my main point was 
minimal contrast. Under normal lighting conditions a dark blue writing on 
black background is indeed hard to read. And that is what Lynx is using by 
default. (Of course, putting "show_color=never" into ~/.lynxrc works just 
fine, apart from "color" being American spelling).
