The CU Boulder Sleep and Development Lab is looking for participants for a research study to learn about how light exposure in the evening affects pupil size in adolescents. We need children ages 15.0–16.9 years who are healthy and have no sleep problems for a six-day study, requiring one short visit to our lab (approximately two hours). Families will be compensated for participating.
