NCT ID NCT07625358
First seen Jun 05, 2026 · Last updated Jun 16, 2026 · Updated 3 times
Summary
This study looks at how caffeine and alcohol change the way your pupils react to light and how your eyes move. Researchers will give 100 adults either caffeine, alcohol, or a placebo drink, then use a portable device to measure pupil size, eye movements, and other eye health markers over two hours. The goal is to see if these changes can help create a quick, non-invasive test to detect recent caffeine or alcohol use for safety and medical purposes.
