KEY HIGHLIGHTS:

  • The purpose of this study was to determine the role of vision and visual attention factors in automobile crash involvement.

  • This was a prospective, population-based study conducted on 1801 drivers aged 65 to 84 years.

  • 120 (6.7%) of the sample drivers were involved in a crash during the observation interval.

  • Glare sensitivity and binocular field loss were significant predictors of crash involvement (P < 0.05).

  • Participants with moderate or better vision increased glare sensitivity or reduced visual fields were, paradoxically, associated with a reduction in crash risk.

  • For participants with poorer levels of vision, increased glare sensitivity or reduced visual fields were associated with increased crash risk.

  • Worse UFOV score was associated with increased crash risk.

  • Glare sensitivity, visual field loss, and UFOV were significant predictors of crash involvement.
