The BIFOCAL Project studies the effects of bifocal usage on falling. The project will gather functional, vision and fMRI (functional magnetic resonance imaging) data to better understand how bifocal eyewear contributes to falls and the process by which the brain adapts to visual information as received through multifocal lenses. Collaborators include St. Marys Hospital in Madison, Wisconsin and Prism Clinical Imaging/the Medical College of Wisconsin who partner with the R2D2 Center in data collection and analyses. The National Institute on Disability and Rehabilitation Research (NIDRR) funds the three-year project.
