AN EVALUATION OF THE TRAFFIC SAFETY RISK OF BIOPTIC TELESCOPIC LENS DRIVERS

This report evaluates the traffic safety risk posed by licensed drivers who wear a bioptic telescopic lens device while driving. Because of low vision, bioptic telescopic lens (BTL) drivers wear eye glasses with a miniature telescope attached to the upper part of the standard carrier lenses (generally only the lens for the driver's better eye). The telescope enhances distance visual acuity, and is used for quick scanning of traffic signs and signals. In the present study, the 2-year (1993-1994) total accident, fatal/injury accident, and total citation rates for BTL drivers were compared to those for a comparison group. The purpose of the study was to determine whether BTL drivers pose an increased risk to traffic safety compared to non-BTL drivers of similar age and sex. The results of the study indicate that the two groups differed significantly on the criteria studied. The adjusted total and fatal/injury accident rates for the BTL group were 1.9 and 1.7 times higher than those for the comparison group, respectively. However, an opposite result was found for total citations; the adjusted rate for the BTL group was 0.7 for the adjusted rate for the comparison group on this measure.
