Purpose: This study aimed to investigate the prevalence of impairment of visual function amongst European drivers.Methods: A total of 2422 drivers from five European countries underwent a battery of visual function tests, including tests for visual acuity (VA), visual field (VF), contrast sensitivity, straylight (glare sensitivity) and useful field of view (UFOV). Subjects belonged to the following age categories: 45[ndash]54 years; 55[ndash]64 years; 65[ndash]74 years, and [ge] 75 years. A group of subjects aged 20[ndash]30 years served as a reference group. Results were compared with current standards for the visual function of drivers in the EU.Results: Visual acuity in 0.5% of the younger group and 5.3% of the eldest group was below the standard required for driving. Visual acuity after proper refraction adhered to the standard
