What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether a wearable device that tracks and reminds children to spend more time outdoors can help prevent nearsightedness (myopia). Primary school students with adequate hyperopic reserve—a natural buffer against myopia—will be randomly assigned to either a program using smart wristbands to encourage at least 1-2 hours of outdoor activity daily, plus standard eye health education, or education alone. Over 12 months, researchers will measure changes in eye length and refractive error to see if the outdoor activity program reduces the onset of myopia.

What this could mean

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

Active substance
Wearable device-supported outdoor activity program
What this could lead to
If effective, this program could offer a simple, scalable way to reduce myopia risk in children, potentially lowering the global burden of nearsightedness.
What could go wrong
The trial is relatively small and short-term, and results may not generalize. Adherence to outdoor activity targets could be challenging, and the wearable device's reminders may not be enough to change behavior.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 104 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jun 2026

Expected to finish

Dec 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

6 to 11 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Students in grades 1 to 4 from participating schools. * Non-myopic children with adequate hyperopic reserve at baseline, defined as cycloplegic spherical equivalent refraction in the worse eye within the following age-specific reference ranges: +1.72 D to +2.45 D at age 6 years; +1.48 D to +2.00 D at age 7 years; +1.19 D to +1.79 D at age 8 years; +1.11 D to +1.38 D at age 9 years; +0.92 D to +1.16 D at age 10 years; and +0.83 D to +1.07 D at age 11 years. * Written informed consent provided by a parent or legal guardian, with assent obtained from the child when appropriate. Exclusion Criteria: * Strabismus, amblyopia, or other ocular abnormalities. * Systemic disease or other medical conditions that may affect study participation. * Has received any myopia prevention intervention in the past 3 months. * Any other condition judged by the study doctors to make participation inappropriate.
