    "definition": "This phenotype identifies individuals with evidence of vision problems recorded in routinely collected electronic health records. Visual impairment is a recognised risk factor for falls by reducing environmental awareness, depth perception, and hazard detection. The phenotype is intended for use in studies of falls risk assessment, epidemiology, risk prediction, and evaluation of fall prevention interventions. Case ascertainment is based on diagnostic or clinical codes recorded in primary and/or secondary care electronic health records.\n",
