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.

Siūlyčiau prie progos užsukti pas oftalmologą ir pasitikrinti šitą 
reikalą, nes dauguma žmonių net neįtaria, jog turi šią problemėlę.
