Glaucoma and its effects on sleep, mood, and thinking
This study looks at how glaucoma affects your body's natural light sensing, which can impact sleep, alertness, mood, and memory. Researchers compare people with glaucoma to healthy volunteers to understand these effects better.
SingaporeAges 45–75 - NCT07369804Recruiting
Red-light therapy for myopia in adults
This study tests whether a special red-light device can safely slow or stop nearsightedness from getting worse in adults. You'll use the light at home for a few minutes each day, and the team will check your vision over time.
Hong Kong, Hong KongAges 18–50 - 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 - 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+ - 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 - NCT07476053Recruiting

- How do I know if I qualify for a light trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a light trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
