In order to develop hygienic standards for information view on a personal computer display, a model (laboratory) experiment on high school students was performed. A wide scope of variants of information display (15 color combinations of alogical tests consisting of 7000 symbols vs. reading from a sheet of paper) was used, and the response of the visual system was studied. The response of the viewers was assessed according to reading speed taking into account the number of mistakes, which made it possible to determine visual task complexity for each variant of the test. The second parameter under study was mistake dynamics, counted according to the number of mistakes per each thousand of symbols read. The data obtained demonstrated that to high school students reading a PC monitor was a significantly more difficult visual task than reading a sheet of paper. The following color combinations on the computer display were most favorable: blue text on a yellow background, yellow text on a blue background, and red text on a green background.
