Aged Drivers May Experience Decreased Visual Function While Driving
The purpose of this study was to investigate the conventional visual acuity (VA) and changes therein over time in older drivers.
This was a cross-sectional study of 124 randomly selected subjects.
There was correlation between age and visual acuity (P<0.05) for young drivers.
Visual acuity scores less than 0.7 was significantly higher in the older drivers than in the younger drivers.
The Trail Making Test B scores were significantly higher in the older group than in the younger and middle-aged groups.
The study shows that older drivers might experience decreased VA and increased frequency of VA loss while driving.
