Abstract
Práce se zabývá studií rozlišování barev u skupiny osob s kataraktou - šedým zákalem. Měření rozlišování barev se provádělo pomocí FM 100 Hue testu. Vyhodnocovalo se procentuální zlepšení vnímání barev před a po operaci katarakty a porovnávaly se výsledky rozlišování barev mezi osobami s kataraktou a osobami bez katarakty. Dále se pro zvolené skupiny osob s kataraktou určily oblasti, ve kterých byly barvy rozlišovány s nejmenší úspěšností. Výsledky se také porovnávaly s charakteristikami vad vnímání barev. Simulace sníženého vnímání barev se uskutečnila pomocí počítačového programu Color Vision Filter. Navržené postupy programu umožňují podle výsledků FM 100 Hue testu přetransformovat scénu do barev, jak je vidí testovaná osoba. Získané znalosti je možné dále využít pro specifický design určený osobám se sníženým vnímáním barev.
This work investigates the color discrimination in a group of persons with cataract. Measurement of color discrimination was made using FM 100 Hue test. Author evaluated the percentage improvement in color perception before and after cataract surgery and compared the results of color discrimination between persons with cataract and persons without cataract. Furthermore, for selected groups of people with cataract have been identified the areas in which they distinguished colors with the least success. The results are then compared with the characteristics of color vision defects. Simulation of a reduced color perception was carried out using the computer program Color Vision Filter. Designed procedures allow the program to transform the scene into colors according to the results of FM 100 Hue test, as seen by the tested person. Gained knowledge can be used for specific design for persons with low color discrimination.
