NCT ID NCT07186088
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests whether repeated low-intensity red light can treat myopia (nearsightedness) in adults aged 18 to 35. Thirty participants will use a red light device 1 to 3 times daily. Researchers will measure changes in eye length and prescription strength to see if the treatment is safe and effective.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- low-intensity red light
- What this could lead to
- If it works, this could offer a non-invasive way to control or reduce myopia in adults, potentially reducing dependence on glasses or contacts.
- What could go wrong
- This is a very small early study (30 people) with no control group, so results may not be reliable. The long-term safety of repeated red light exposure is unknown.
