Study Summary
The purpose of the study is to test the use of amber glasses at night as a method to block blue light from the eye, allowing the brain to produce a dim-light melatonin onset. The investigators hypothesize that blue-blocking will produce measurable benefits in subjectively and objectively rated sleep quality and mood as well as salivary melatonin levels during the night.
Primary Outcome
Hourly saliva samples will be collected from participants at the end of each 4 night interval in order to measure levels of melatonin production.
