<div><p>Little is known about the prevalence and association between visual impairment, low vision acuity, and sleep indicators (sleep duration and sleep problem) in the Indian context. We investigate this association for Indian older adults (50+ ages). Using cross-sectional data from WHO-Study on global AGEing and adult health (WHO-SAGE) 2007–2008, a sample of 6560 (<i>M</i><sub>age</sub> = 61.81, <i>SD</i> = 9.00) was selected for analysis. Self-reported visual impairment and performance-based low vision acuity were used as outcome variables, whereas sleep duration, problem in sleep, and medical condition with socio-demographic were used as covariates. Multivariate logistic regression analyses were conducted. In a fully adjusted model (including all covariates), vision impairment was associated with short sleep duration (<6 hr) and sleep problem, separately and together for both genders. Low vision was positively associated with short sleep duration and sleep problem, separately and together for males, whereas only long sleep (⩾9 hr) is associated with low vision acuity for females in fully adjusted model. Results suggest that sleep apnea including short sleep duration and sleep problem is the underestimated cause of visual impairment and vision acuity. Healthcare providers should consider sleep parameters (sleep duration and sleep problem) along with sleep apnea in the treatment of visual impaired older adults.</p></div>
