Individually Tailored Lighting System to Improve Sleep in Older Adults

We will recruit 50 subjects who report going to bed early and desiring later bedtimes and will ask them to wear an active and an inactive light mask for 8 consecutive weeks each. A 2-week washout period between active and inactive conditions will be applied. Outcome measures will be collected periodically throughout the 8 weeks. Baseline (no intervention) will be collected prior to the active and inactive lighting interventions.
