How light color affects pupil size study
Part of Eyes & vision clinical trials.
This study looks at how different colors of light change your pupil size. It may help us understand vision and eye health better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 7 and 45 years old.
- You need to have mild to moderate nearsightedness (between -0.50 and -5.00 diopters) with little astigmatism (no more than -1.50 diopters).
- You must be able to wear special sensors and follow instructions during the test.
- You cannot have eye problems like crossed eyes, lazy eye, infections, or glaucoma.
- You cannot have certain health conditions or take medications that affect your nervous system, like antidepressants or sedatives.

This study checks how well a device can measure how your pupils respond to colored light. It may help improve eye testing, especially when monitoring certain vision and nerve conditions.
This study looks at how your pupils react to light in healthy people. It may help doctors understand normal eye responses, which could improve future eye tests.
This study looks at how your eyes react to light and how that relates to your sleep and daily body rhythms. It may help researchers understand sleep problems and find better ways to treat them.
This study looks at how non-visual light (light that isn’t just for seeing) affects your sleep timing and circadian rhythms, and whether the effects differ by sex and age. It may help researchers design better light-based or sleep-support strategies in the future.
This study tests whether different colors of light change how your body or brain responds. You may be asked to spend time under specific lighting while researchers measure outcomes.
This study aims to objectively measure how your pupils respond to light and how your eye muscles react using recording tests. It may help confirm the cause of light sensitivity (especially after a brain injury) and better track how it responds to care.
