Summary

This trial tests whether special glasses with defocus lenses, aided by artificial intelligence, can prevent myopia in children aged 3 to 6 who are at high risk. The glasses are worn for at least 10 hours a day, and a smartwatch reminds kids to spend time outdoors. The study measures changes in eye length and vision to see if this approach slows or stops the onset of nearsightedness.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: AI-assisted defocus spectacle lenses (AI-DIMS TED) and smartwatch reminders to encourage outdoor time
What this could lead to: If effective, this approach could offer a practical way to slow or prevent myopia in young children, reducing future risk of high myopia.
What could go wrong: The trial is small and early, and results may not apply to all children. The glasses require consistent wear, and long-term benefits are not yet proven.
