AbstractThe visual system affects circadian rhythms, and both visual and sleep difficulties are common in older adults. This study examines the association between visual impairment, age-related eye disease, and sleep disturbances among older adults in the United States. This cross-sectional study used Round 11 of the National Health and Aging Trends Study (NHATS). Vision was assessed using self-report and objective assessments (distance and near acuity, contrast sensitivity).
