Summary
Brief summary
Poor vision is a risk factor for falls among older people but it is not known whether improving vision prevents falls. In this study, subjects in the intervention group have a comprehensive eye examination and receive appropriate treatment. It is hoped that this will result in fewer falls over the next 12 months than in an untreated control group.
