Night driving and assessment of mesopic vision for older adults

For many older adults, night driving is difficult due to age-related changes affecting vision under low light and glare conditions. However, there is a lack of evidence for healthcare practitioners to base their advice to patients about visual fitness to drive safely at night. This research investigated the relationships between self-reported vision-related night driving difficulties, visual function tests and night driving performance. It was found that vision tests conducted under lower light levels, similar to the night driving environment, were important for predicting poorer night driving performance and for assessing drivers reporting high levels of vision-related night driving difficulties
