About this trial

This study is for testing the efficacy and safety of distance-image screens for preventing myopia in children for 12 month. Each subjects would be asked to paired test the ocular parameters between before and after 12-month distance-image screens.

Treatments tested in this trial

  • distance-image screen

    Device

    Distance-image screen is a screen make each image at distance of 6-meters to reduce the accommodation and convergence for eyes during the reading and learning with screens.

Trial outcomes

Primary outcomes

1

Changes of ocular axial length (mm)

IntraOcularLens (IOL) master biometry will exam each eye before the testing and after the testing with distance-image screen

Time frame
12-month
2

Changes of refractive error (D)

Cycloplegic refraction with autorefractor will test each eye before the testing and after the testing with distance-image screen

Time frame
12-month

Secondary outcomes

1

Changes of center macular thickness (um)

Optic Coherent Topograph (OCT) of macular fovea central thickness will be made to compare the thickness before and after using distance-image screen

Time frame
12-month
2

Changes of subretina choroidal thickness (um)

Optic Coherent Topograph (OCT) with Enhanced Depth Imaging (EDI) scan of macular fovea central thickness will be done to compare the thickness before and after using distance-image screen

Time frame
at 12-month
3

Changes of other regions choroidal thickness (um)

Optic Coherent Topograph (OCT) with Enhanced Depth Imaging (EDI) scan of other regions choroidal thickness will be done to compare the thickness before and after using distance-image screen

Time frame
12-month
