This study is looking at how much time children with myopia (nearsightedness) spend looking at things up close and how much time they spend outdoors. Researchers will use a special clip-on sensor called Vivior, attached to glasses, to measure these behaviors. The goal is to understand how these factors affect the effectiveness of current myopia control treatments. You may be able to join if you are between 6 and 14 years old and have myopia. The study will measure near viewing duration, near viewing distance, and outdoor time over 12 months to help doctors better manage progressive myopia.

Study design

This is an observational study planning to enroll 230 participants. It is not a treatment study but rather aims to understand behaviors.

What's involved

Participants will wear a Vivior clip-on sensor on their glasses for 12 months, which will objectively measure near viewing and outdoor time.

Compensation

Not stated in the trial record.

Follow-up

Participants' near viewing duration, near viewing distance, and outdoor time will be measured for 12 months.
