About this trial
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.

Trial outcomes
Primary outcomes
1
Assessment of attention
To measure the impact of the intervention on attention, for each student we will measure the time it takes for the student to complete the provided test, and the number of errors in the test. Each student will completed the test, before and after the intervention, and the change in test score (time and errors) calculated.
Time frame
3 weeks. One test per weekSecondary outcomes
1
Determine how time of day impacts attention
To determine how time of day impacts attention, we will reanalyze the data from "Outcome 1", and control for the time of day the students participated in the study. We will measure the time it took to complete the test, as well as the number of errors in the test.
