Comparison of the visual function index to the Snellen Visual Acuity Test in predicting older adult self-restricted driving.

Objective: In this observational study, a modified version of the Visual Function Index (VF-14) and the Snellen Visual Acuity Test were compared in how well they correlated with self-restricted driving habits in older adults. The VF-14 was originally designed to assess vision in cataract patients; however, in this study, a modified version (mVF-14) was evaluated as a tool for predicting self-restricted driving in older drivers.

Methods: During a 3-month period, 151 drivers over the age of 65 were screened at the local senior center.
