Scientists find pupils change size with breathing, potentially impacting vision and diagnosing neurological issues.
Scientists discovered that our pupils change size in sync with our breathing, with the pupil being smallest during inhalation and largest during exhalation.
This phenomenon, observed in over 200 participants across five experiments, persists regardless of lighting, focus distance, or mental effort.
This cyclical change in pupil size could affect how we see and may help diagnose neurological conditions.
