LRC Recruiting Participants for Paid Study: Investigating the Effects of Light at Night

The Lighting Research Center (LRC) is recruiting participants over the age of 18 for a study that will take place on five consecutive Fridays – March 29th, April 5th, April 12th, April 19th and April 26th. 
 
To determine eligibility for the study, participants will need to come to the LRC and have their Macular Pigment Optical Density measured. This procedure will take approximately 10 minutes. This is performed using equipment widely used at ophthalmologist offices. While looking into the eyepiece, participants will be asked to push a button when they see a flicker of light. Results from this test will determine eligibility for the study. Participants will not be paid for coming to the LRC to have this screening performed. 
 
Once accepted into the study, participants will need to attend all five scheduled sessions, unless withdrawing from the experiment.  In order to be eligible, participants need to regularly have bedtimes no later than 11:30 pm and wake up no later than 8:00 am. Participants will be asked to keep this regular schedule all the weeks of the study. Participants will be asked to wear an actigraph and keep a sleep log all 5 weeks of the study.
 
Participants will arrive at the LRC at 11:30 pm each Friday night.  Starting at midnight, participants will be sitting in front of a light bar for 1 hour with their chin in a chin rest. Participants will also be asked to collect 3 saliva samples during this 60 minutes. Participants will receive four different lighting conditions, one each week, and a dark condition with no light exposure. 
 
Individuals with major health problems and those who take prescription medication (except birth control pills) are not eligible to participate. Individuals will not be allowed to participate if traveling more than one time zone the week before or during the weeks of the study.

Participants will be paid $65 for each nighttime session for a total of $325 for all five weeks. Payment will be processed by Rensselaer after completion of each session. If you are interested in participating in the study, please contact Barbara Plitnick at plitnb@rpi.edu for more information. Thank you! 


About the Lighting Research Center
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is the world's leading center for lighting research and education. Established in 1988 by the New York State Energy Research and Development Authority (NYSERDA), the LRC conducts research in light and human health, transportation lighting and safety, solid-state lighting, energy efficiency, and plant health. LRC lighting scientists with multidisciplinary expertise in research, technology, design, and human factors, collaborate with a global network of leading manufacturers and government agencies, developing innovative lighting solutions for projects that range from the Boeing 787 Dreamliner to U.S. Navy submarines to hospital neonatal intensive-care units. In 1990, the LRC became the first university research center to offer graduate degrees in lighting and today, offers a M.S. in lighting and a Ph.D. to educate future leaders in lighting.
