Purpose: The ability to drive has been shown in countless studies to have a positive effect on an individual's quality of life and self-worth. Driving cessation has shown to have the opposite effect. Most states within the US, and some other countries, allow for some form of driving licensure with the aid of bioptic telescope spectacles (BTS). BTS consist of a small telescope, fit monocularly, and mounted in the upper portion of a distance prescription lens. The telescope is used for distance spotting tasks such as road signs and traffic lights while driving. There have been previous studies which have investigated the driving exposure of this unique driving population. These previous studies have mainly used self-report of miles driven as their collection method, but the accuracy of this method is unclear. The purpose of this study was to compare estimates of self-reported mileage driven with estimates obtained using naturalistic recording in bioptic drivers' own cars. Methods: Visual acuity (logMAR charts), contrast sensitivity (Pelli-Robson or Mars charts), age, and sex were collected from clinic records at the Ohio State University College of Optometry. A modified version of the Driving Habits Questionnaire was administered in person. A commercially-available in-car recording system with video and GPS capability was installed in subjects' cars and driving was recorded for one to three months. Estimates of weekly mileage and trips obtained using the questionnaire and the recording system were compared to assess concordance. Results: Ten licensed Ohio bioptic drivers (six male) were included. Mean (±SD) age was 53±20 years. Mean binocular logMAR visual acuity was 0.68 ± 0.14, or approximately 20/100. Mean contrast sensitivity was 1.44 ± 0.13. Self-reported weekly mileage ranged from 1 to 800 miles per week (264 ± 252), and recorded mileage ranged from 5.8 to 842.6 (244 ± 298). There was a strong correlation between estimates from the two methods (Spearman correlation = 0.70, P = 0.025). Conclusion: Self-reported estimates of bioptic driving mileage were generally well correlated with estimates obtained from in-car recordings in this small sample of bioptic drivers. These findings have implications for the use of self-reported methods in adjusting for driving exposure in studies of driving safety. It is likely that both objective and subjective measurements may have a role in the determination of driving exposure for studies of driving safety.
