jau sen gribēju pagūglēt, beidzot saņēmos, biju nopietni pārsteigts, ka astigmātisms ir tik ļoti izplatīts, ja tic tam, ko var izlasīt internetā:

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.

ja tā ir tik ļoti izplatīta lieta, kāpēc steams ir tumšs uz gaiša? fukin kaitina :D
