This paper presents a research of in fluences of coffee on dynamic parameters of eyeballs movements. In this study we made use of a head-mounted saccadometer which measures parameters related to eyeball movement (duration, latency, amplitude, peak velocity). 19 people, selected by age, took part in the study. Coffee-consuming group subjects were chosen at random for the experimental group and proper subjects were assigned to the control group without taking coffee. The results of the study were divided into two groups: the first related to saccade dynamics and the second related to reaction time (latency) and accuracy. The statistical significance has not been found in the saccadic duration, amplitude and peak velocity. A significant difference in latency was observed in the Coffee-consuming group, though an increase in the number of mistakes (errors of saccade accuracy) was not observed. In reverse, in the Coffee-consuming group was observed a decrease in the errors of saccade accuracy.
