Assessment of the Efficacy and Safety of a DYnaMic Peripheral DegradatiON Myopia Disorder Control in Myopic Children ״DYMOND Study״
Randomized Controlled Double Masked, Trial to Assess the Efficacy and Safety of a DYnaMic Peripheral DegradatiON Myopia Disorder Control in Myopic Children Compared to No Treatment (DYMOND Study)

Conditions
Summary
The DYMOND study evaluates the safety and effectiveness of TrackSight™, a digital medical application designed to slow myopia (nearsightedness) progression in children during everyday screen use. TrackSight uses eye-tracking technology to keep central vision clear while subtly adjusting the image in the peripheral viewing area, based on established scientific principles known to influence eye growth. Up to 150 children aged 6 to 12 with myopia will participate at sites in Israel and Hong Kong. All participants will continue wearing their regular single-vision glasses and will be randomly assigned to use TrackSight with or without active visual adjustment for 12 months. Eye examinations and safety assessments will be conducted at the start of the study and after 6 and 12 months. The study aims to determine whether this non-invasive digital approach can safely slow myopia progression in children.
Eligibility
Inclusion Criteria7
- Aged 6-12 years
- Diagnosed with myopia: cycloplegic spherical or spherical equivalent (SER) between -0.75D and -5.00D, astigmatism ≤ -1.50D, anisometropia \< 1.50D

Exclusion Criteria6
- Past or concurrent use of any other myopia treatment (e.g., atropine, orthokeratology, myopia control glasses/lenses)
