Study Summary

The purpose of this research study is to investigate the relationship between light, the thickness of the pigment at the back of your eye, melatonin levels, and memory. The study will investigate whether changing light distribution pattern from "on-axis"' (i.e., directed along the eye's visual axis to the fovea) to "off-axis" (i.e., directed on the periphery of the eye's visual axis) impact melatonin suppression in 24 mild cognitive impairment participants and 24 healthy, age-matched controls.

Primary Outcome

Saliva samples collected for melatonin levels for the different conditions. Blue light (λmax = 451 nm) on axis and off axis: for each narrowband source, designated on-axis or off-axis, will have distinct lighting distribution patterns but calibrated to deliver the same targeted levels of circadian light (CLA) and circadian stimulus (CS) at the eye. Green light (λmax = 522 nm) on and off axis: for each narrowband source, designated on-axis or off-axis, will have distinct lighting distribution pa
