Investigational drug(s) / intervention(s)
Virtual Far-sight Reading Device
Virtual Far-sight Reading Device: The Virtual Far-sight Reading Device utilizes a birdbath optical configuration and freeform surface technology to extend the working distance from 30 cm to over 6 meters, thereby simulating distance viewing conditions and maintaining ciliary muscle relaxation. Study participants were required to engage in reading and writing tasks using the device for a cumulative daily duration of at least 1 hour.
Study summary
This clinical trial wants to find out if the Virtual Far-sight Reading Device can help prevent or slow down myopia progression in children and teenagers with pre-myopia. We also want to know what makes this treatment work better for some participants and check for any eye or body-related side effects over time.
Main questions:
Can using the Virtual Far-sight Reading Device reduce the risk of myopia? Is the device safe to use every day for up to 6 months?
What we'll do:
Researchers will compare two groups of children:
Group A: Uses the device for reading/writing (at least 1 hour daily) Group B: Does regular reading/writing without the device After 90 days, the groups will switch to see if the results stay the same.
Participants will:
* Have free eye checkups 3 times over 6 months
* Use the device during homework time (if in the desk group)
* Report any eye discomfort or problems
