COMPREHENSIVE VISION TESTS AND DRIVING RECORD

TWO GROUPS OF DRIVERS, BETWEEN THE AGES OF 50 AND 70, THOSE WITH POOR DRIVING RECORDS AND THOSE WITH CLEAN RECORDS, WERE REQUIRED TO TAKE A COMPREHENSIVE SET OF VISUAL TESTS. THE PURPOSE OF THIS RESEARCH WAS TO DETERMINE WHETHER POOR-RECORD DRIVERS ARE VISUALLY AS COMPETENT AS CLEAN-RECORD DRIVERS, WHETHER THERE IS A RELATIONSHIP BETWEEN VARIOUS MEASURES OF VISION AND DRIVING PERFORMANCE, AND WHETHER THERE IS ANY VISION MEASUREMENT THAT SHOULD BE INCLUDED IN THE VISION EXAMINATION TO LICENSE APPLICANTS FOR WHICH THEY ARE NOT NOW TESTED. THE MOST SIGNIFICANT FINDINGS OF THIS RESEARCH ARE AS FOLLOWS: (1) ON THE AVERAGE POOR RECORD DRIVERS ARE VISUALLY MORE COMPETENT THAN CLEAN-RECORD DRIVERS IN TERMS OF STATIC AND DYNAMIC VISUAL ACUITY AND GLARE VISION. IN ADDITION, FEWER POOR-RECORD DRIVERS HAVE DIPLOPIA AND THEIR ANNUAL MILEAGE IS GREATER THAN DRIVERS WITH CLEAN RECORDS, (2) HIGH INTER-CORRELATIONS WERE FOUND BETWEEN DYNAMIC AND STATIC VISUAL ACUITY MEASURES, AND (3) ALTHOUGH THE POOR-RECORD DRIVERS WERE VISUALLY MORE COMPETENT THAN THOSE WITH CLEAN RECORDS IN THE TEST FOR GLARE VISION, A LARGER PROPORTION OF THOSE WITH POOR RECORDS HAD ALMOST NO GLARE VISION. /AUTHOR/
