Can red light stop Kids' eyes from getting worse?
NCT ID NCT07208617
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial tests a red light device that uses LED light to control myopia (nearsightedness) in children aged 6 to 18. About 206 kids will use either the real device or a fake one to see if the red light can slow eye growth and reduce the need for stronger glasses. The study focuses on safety and how well it works over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- red light device using LED light source
- What this could lead to
- If it works, this could offer a simple, non-invasive way to slow down worsening nearsightedness in children, reducing the need for stronger glasses or future eye problems.
- What could go wrong
- This is an early-stage trial with only 206 participants. The device may not work better than a placebo, and long-term safety or effectiveness is not yet known.

Inclusion Criteria: * Willing to use myopia treatment devices based on LED light sources or fake light sources Aged 6-18 years old For both eyes, the myopic spherical equivalent refraction after cycloplegic computerized refraction: -0.50D to -6.00D, and astigmatism ≤ 2.50D Spherical equivalent anisometropia of both eyes ≤ 2.50D Corrected visual acuity (for both near and far) ≥ 1.0 Intraocular pressure (IOP) 10-21mmHg No active ocular inflammation, no history of ocular trauma, no history of ocular surgery, and no ocular or systemic organic diseases that affect visual changes Voluntarily participate in this project and sign the informed consent form The subject has not used other myopia control methods in the past six months Have records of refractive error and axial length measurements six months before enrollment Exclusion Criteria: * Subjects with systemic diseases or immune diseases that affect compliance, such as tumors, heart diseases (including those with implanted electronic devices in the body, such as cardiac pacemakers), severe liver and kidney diseases, epilepsy, and autoimmune diseases Subjects with mental illnesses that affect the implementation of the intervention measures in this trial Subjects with refractive media opacity (corneal lesions, lens opacity, etc.) or ocular diseases: macular diseases, moderate to severe dry eye, corneal diseases, cataracts, vitreoretinal diseases, infectious conjunctivitis, uveitis, optic nerve damage, congenital optic nerve dysplasia, or other ocular diseases Subjects allergic to cycloplegics Other circumstances where the researcher deems it inappropriate for the subject to participate in the trial for safety reasons or in the interest of the patient
