NCT ID NCT05631236
First seen Jun 27, 2026 · Last updated Jul 22, 2026 · Updated 2 times
Summary
This study tests whether wearing bright light glasses can improve sleep, thinking, and physical strength in older veterans. The glasses emit a special blue light that may help reset the body's internal clock. Researchers will measure sleep quality, balance, and coordination in 43 participants to see if this simple home-based approach can reduce frailty and boost cognitive resilience.
