What is being tested?
The study is exploring how different levels of light during the day affect our body's response to light in the evening. This could help understand how daytime light influences sleep quality and other non-visual responses to light.See study design
What are the potential side effects?
Since this trial involves exposure to varying intensities of light without any drugs or invasive procedures, side effects are minimal but may include eye strain or headache due to bright lighting conditions.
