What the study is about

Humans are constantly exposed to a variety of light types, created naturally or through artificial means. Light exposure captured by the eyes impacts many physiological functions in humans, including but not limited to cognitive output, fatigue levels, and mood regulation. The level of impact on cognitive learning from different types of light on undergraduate adult students remains unclear.

Being studied: Light emitting glasses

Conditions: Healthy

Eligibility criteria

Copied from the official record. The study team makes the final decision at screening.
