About
Ulrich Schiefer’s research lies at the critical intersection of visual psychophysics, road safety, and aging, with a primary focus on quantifying how specific visual impairments degrade real-world performance—particularly night driving. His most-cited work, a 2022 study on contrast sensitivity and night driving in older people, demonstrates that contrast sensitivity is a far stronger predictor of hazard detection distance than conventional high-contrast visual acuity, challenging long-held clinical assumptions. This paper, with 21 citations, has already influenced discussions on driver licensing standards. In a complementary 2022 study, Schiefer investigated whether intraocular straylight—a measure of glare susceptibility—can predict night driving visual performance, finding correlations between straylight levels, contrast sensitivity, halo size, and hazard recognition under glare conditions. These contributions are notable for their methodological rigor: Schiefer employs advanced driving simulators and precise psychophysical measures to bridge the gap between clinic-based vision tests and the complex visual demands of nighttime mobility. His work has direct implications for developing more effective vision screening protocols for older drivers, aiming to reduce accident risk while preserving independence.
