Wearing Behavior and Eye Length Changes in Children With Myopia Wearing Myopia Control Spectacle Lenses
A study testing Single Vision Lens (SVL) in people with Myopia, run by Essilor International at 1 site in Singapore.
Trial summary
The goal of this clinical trial is to learn how children with myopia aged 8 to 15 years move their eyes and heads during near-vision tasks while wearing different spectacle lenses, and if wearing myopia control spectacle lenses for one month is related to change in eye length (axial length).

About this study
Official title: Wearing Behavior and Short-Term Changes in Axial Length in Children With Myopia Wearing Myopia Control Spectacle Lenses
The goal of this clinical trial is to learn how children with myopia aged 8 to 15 years move their eyes and heads during near-vision tasks while wearing different spectacle lenses, and if wearing myopia control spectacle lenses for one month is related to change in eye length (axial length). The main questions it aims to answer are:
- How do eye gaze position and head movement patterns change when children wear the commercially available myopia control spectacle lenses compared with single-vision spectacle lenses?
- Does wearing myopia control spectacle lenses for one month lead to short-term changes in axial length?

This study compares commercially available myopia control spectacle lenses with single-vision spectacle lenses to evaluate differences in eye gaze position, head movement patterns, and axial length.
Participants will:
- Attend three study visits at the Singapore Polytechnic Optometry Centre.
- Wear the assigned study spectacles while performing near-vision tasks.
- Have video recordings of their face collected, to evaluate eye and head movements, during the near-vision tasks.
- Conditions
- Myopia
- Being tested
- Single Vision Lens (SVL), Myopia Control Lens (MCL)
- Keywords
- eye gaze, lens gaze, head movement, myopia control
- Medical subject headings
- Myopia
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Single Vision Lens (SVL)Device
Standard, commercially available single vision spectacle lenses worn on-site during near vision task assessment at Visit 2 and Visit 3.
Myopia Control Lens (MCL)Device
Commercially available Stellest® spectacle lenses worn on-site during near vision task assessment at Visit 2 and Visit 3, and worn continuously for approximately 1 month between Visit 2 and Visit 3.
| Study group | Role | What they receive |
|---|---|---|
| Sequential Lens Evaluation | Experimental | Single-arm, within-subject design; Each participant received both Single Vision Lens (SVL) and Myopia Control Lens (MCL) spectacles. Receives: Device: Single Vision Lens (SVL); Device: Myopia Control Lens (MCL) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in eye gaze position
Eye gaze positions are derived from post-processed video recordings of participants performing near-vision tasks while wearing the study spectacles.
Measured: Visit 1 (Baseline), Visit 2 (1-2 weeks), Visit 3 (1-month)
Change in axial length
Measured: Visit 2 (Baseline), Visit 3 (1-month)

Questions about this trial
What is this clinical trial studying?
A study testing Single Vision Lens (SVL) in people with Myopia, run by Essilor International at 1 site in Singapore.
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 10 inclusion and 2 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: finished, as of the sponsor's last update on 24 Aug 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 Singapore. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in eye gaze position (time frame: Visit 1 (Baseline), Visit 2 (1-2 weeks), Visit 3 (1-month)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07780851, which also lists 3 linked publications.
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 24 Aug 2026.
