Red-light sessions to slow worsening nearsightedness
This study tests whether repeated low-level red-light therapy can slow how fast nearsightedness (myopia) gets worse in children. It may help protect future eyesight, but your child must meet specific vision and health requirements and follow the study plan.
San Francisco, CaliforniaAges 8–13 - NCT05579392Recruiting
Bright light therapy for gut inflammation in Crohn’s or colitis
This trial studies whether daily bright light can improve gut barrier “leakiness” and reduce inflammation in adults with Crohn’s disease or ulcerative colitis. It compares bright light versus dim light in a crossover design, meaning you may receive both.
Chicago, IllinoisAges 18 years+ - NCT05519878Recruiting
Light plus job therapy for fatigue in genitourinary cancer
This trial tests whether light therapy and an occupational therapy fatigue program can reduce fatigue in people with certain urinary-system cancers who still have mild fatigue during treatment. It may help you feel more energized and manage day-to-day activity while cancer treatment is ongoing.
Duarte, CaliforniaAges 18 years+ - NCT02660645Recruiting
Blue light bladder scan for suspected bladder cancer
This trial uses a special blue-light camera during a bladder procedure to help doctors better see non-muscle-invasive bladder cancer. It may help find cancer spots more clearly so they can be treated sooner.
Birmingham, AlabamaAges 18 years+ - NCT04578249Recruiting
Blocking blue light at night after heart surgery
This trial tests whether reducing blue light at night after certain planned heart surgeries helps protect mood, thinking, and recovery. If you have no history of major mental health problems or organ problems, you may be able to join the study.
Morgantown, West VirginiaAges 45–75 - NCT04504721Enrolling by invitation
Light therapy for fibromyalgia using blue-enriched white light
This study tests whether a specific type of light (blue-enriched white light) can reduce symptoms of fibromyalgia. It may help people feel better by changing how the body responds to light.
TaipeiAges 20–64 - NCT03811964Recruiting
Test how light affects your sleep, mood, nerves, and vision
This study uses a light-based test (the “photomotor reflex”) to see how non-visual effects of light may affect sleep-wake timing, brain function, mental health, and eyesight. You may be assigned to a group based on your condition, or you may be in the healthy control group.
StrasbourgAges 18 years+ - NCT03203239Recruiting
Red light treatment for circulation problems in leg arteries
This study tests whether a red-light therapy can improve symptoms or function in people with peripheral artery disease (poor blood flow to the legs). You may qualify if your leg circulation test is abnormal and you can safely take part in the study.
Milwaukee, WisconsinAges 18–85 - NCT02370199Recruiting
Blood flow testing using a gentle electromagnetic energy treatment
This study measures how blood flow responds after a non-surgical energy test. It is likely looking for normal, healthy blood-flow reactions and how different people respond.
Milwaukee, WisconsinAges 18–59 - NCT07678723Recruiting
Pupil test to predict blood pressure drop during C-section
This study checks if a simple pupil light reflex test can predict a drop in blood pressure after spinal anesthesia during elective C-sections. If it works, doctors could better manage blood pressure and reduce dizziness or nausea.
DamiettaAges 18–45 - NCT06886906Recruiting
Movement and Pain in Older Adults
