Altered sleep-wake patterns in blindness: a combined actigraphy and psychometric study

• PSQI scores indicate a higher prevalence of sleep disturbances in blind individuals.• Blind individuals have larger variability in the efficiency and timing of their night-time sleep episodes.• Variability measures of sleep efficiency and night-time sleep timing correlate with PSQI scores.• Results cannot be attributed to differences in chronotype between blind and sighted participants.
