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.
