Sažetak
In their everyday life, people interact with different objects, static as well as those in motion. However, dynamic acuity is rarely checked in medical examinations, even those preceding the issue of driving license. In order for driving to be safe, good eyesight or good correction with visual aids is imperative. Beside good eyesight, drivers also have to have good reflexes and short reaction span. The aim of this study was to compare dynamic and static visual acuity in order to observe how they vary among individuals. Twenty female and male participants, 65 years of age, took part in the study and
the comparison was made with the results provided by 20 20-year old participants. Dynamic acuity was tested using the Landolt-ring optotype which was simulating movement velocity of 72 km/h. T-test demonstrated the presence of a statistically significant difference between dynamic and static acuity among the participants from 62 to 68 years of age (t= 15.852; df=39; p<0.01). Within the same group, dynamic acuity (mean=0.887; std. deviation=0.297) proved to be significantly worse than static acuity (mean=1.40; std. deviation=0.317). By comparing the results measured within the
older group of participants with those measured in the younger group, it was shown that there exists a statistically significant
difference (t=0.275; df=58; p<0,05) between the older and younger group in their dynamic binocular acuity with correction. Younger participants had better dynamic binocular acuity with correction (mean=1.063; std. deviation =0.259) than the older participants (mean=0.884; std. deviation=0.298). The differences between dynamic and static acuity and its degradation in the older age groups have to be taken into account when issuing driving licenses. The future of research lies within the study of correlation between the age and acuity in order that the results can be applied in practice.
