Light therapy for dry eye: does skin tone matter?
NCT ID NCT07173530
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at whether low-level light therapy (LLLT) warms the eyelids differently in people with various skin pigmentation levels who also have dry eye or meibomian gland disease. Forty adults will receive three 15-minute sessions over 1-2 weeks. Researchers will measure eyelid temperature and eye symptoms to see if skin color affects treatment response.
