Where children look through their glasses
Official title: Children's Viewing Behavior in Myopia Control Spectacles
Run by SightGlass Vision, Inc. · NCT07229365 · Data updated 2026-11-12
This trial tests how children ages 7–14 look through a new spectacle lens design to see which parts of the lens they use during different tasks.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children aged 7–14 with myopia who are correctable to 20/40 or better, have spectacle power within the study lens range and cylinder ≤ -0.75 DC, and whose parent/guardian can provide consent with child assent.
✕Probably not a fit
Children with systemic diseases affecting ocular health, aphakia, use of systemic or topical medications that affect the eye, inability to complete study activities, or prescriptions outside the study power/cylinder limits are unlikely to benefit from participation.

What this trial studies
This interventional study has children with juvenile myopia wear a novel spectacle lens design while researchers record which areas of the spectacle lens are used during a range of visual tasks. Participants will be screened for eligibility, undergo baseline vision checks, and be fitted with study lenses that match their prescription within the available power range. Viewing behavior will be recorded across activities during scheduled in-person visits at the study site to map lens-zone usage regardless of task. The resulting data are intended to inform placement and design of optics in future myopia-management spectacles.
Why it matters
Potential benefit: If successful, the results could guide spectacle lens designs that place myopia‑control optics where children actually look, potentially improving real-world effectiveness.
How similar studies have gone: Previous work on myopia‑control spectacle designs has shown mixed outcomes, and direct measurement of where children look through lenses is less common, making this a relatively novel behavioral measurement to inform design.

Inclusion Criteria: A person is eligible for inclusion in the study if he/she: * Is 7-14 years of age, inclusive * Requires spherical spectacle lenses within the power range available for the study lenses * Parent/guardian has read and understood the informed consent form, and the child has provided age-appropriate assent * Is willing and able to follow instructions and maintain the appointment schedule * Is correctable to a visual acuity of 20/40 or better (in each eye) with their habitual vision correction or 20/20 best corrected * Has had a self-reported oculo-visual examination in the last two years * Spectacle cylinder of ≤ -0.75DC in both eyes Exclusion Criteria: A person will be excluded from the study if he/she: * Is unable to complete the necessary study activities * Has any systemic disease affecting ocular health * Is using any systemic or topical medications (including pharmaceutical myopia control therapy) that will affect ocular health * Is aphakic
