About this study

Official title: A Randomized Controlled Clinical Trial on the Efficacy and Safety of the Virtual Far-sight Reading Device for Myopia Intervention in Pre-myopic Children

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:

Read more

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
Read the detailed description

The Virtual Far-sight Reading Device is an innovative ocular protection device integrating advanced far-image optical technology, designed to alleviate asthenopia and prevent myopia progression by simulating a long-distance visual environment. Utilizing a birdbath optical configuration and freeform surface technology, it extends the working distance from 30 cm to over 6 meters, mimicking natural distance viewing to induce ciliary muscle relaxation. The device incorporates a cinematic-grade 2K true-color retinal display combined with a peripheral defocus optical design to generate hyperopic retinal shifts, thereby suppressing myopia development. Additional features include an embedded high-resolution AI camera, full-spectrum LED auxiliary lighting (CCT 5000K, CRI >90), and compatibility with extensive e-learning resources, making it suitable for diverse scenarios such as online classes, reading, and writing tasks.

This study employs a randomized controlled crossover trial to evaluate the efficacy and safety of the device in pre-myopic children and adolescents. Participants are divided into Groups A and B, with Phase I (Days 0-90) requiring Group A to perform daily near-work activities using the device for ≥60 minutes of cumulative daily use, while Group B follows conventional near-work practices without intervention. During Phase II (Days 91-180), the interventions are reversed between groups. Comprehensive ophthalmic evaluations are conducted at baseline, Day 90, and Day 180 to assess changes in spherical equivalent refraction (SER), axial length (AL), myopia incidence rate, binocular visual function parameters, and ocular morphological metrics, ensuring rigorous analysis of both therapeutic outcomes and safety profiles.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Virtual Far-sight Reading DeviceDevice

    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.

Model description
This randomized controlled crossover trial was conducted in two sequential phases: Phase I (Day 0-90): Group A: Performed daily near-work activities (e.g., reading/writing) using the Virtual Far-sight Reading Device with cumulative daily use ≥60 minutes. Group B: Engaged in routine near-work activities without intervention. Phase II (Day 90-180): Group A: Switched to standard near-work practice without device use. Group B: Initiated Virtual Far-sight Reading Device intervention under identical protocol (≥60 min/day cumulative use).

Questions about this trial

What is this clinical trial studying?

A study testing Virtual Far-sight Reading Device in people with Myopia and Pre-myopia, run by Shanghai Eye Disease Prevention and Treatment Center at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 26 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Wei Xu, Prof (+86 18521513008, vvxuwei@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in Spherical Equivalent Refraction (time frame: 90 and 180 days from baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 May 2026.
