Longitudinal Visual Diet in Children
Official title: Longitudinal Measurements of Visual Diet in Children
Run by State University of New York College of Optometry · NCT07642999 · Data updated 2026-11-12
This study follows children ages 7–12 to see how everyday visual factors like distance, light, and viewing patterns relate to myopia development over time.

Is this trial a fit for you?
✓Likely a good fit
Children aged 7–12 with astigmatism < 1.50D, good stereoacuity, and normal binocular function; included are both myopic and non-myopic participants meeting cycloplegic refraction criteria.
✕Probably not a fit
Children who cannot wear VEET at home for the required eight days every six months for three years may not benefit from this study’s insights.

What this trial studies
This observational study tracks how a combination of visual environment factors and eye function evolves in children as they grow. Researchers will use the Visual Environment Evaluation Tool (VEET), wearable eye tracking, and regular refraction/biometry to measure viewing distance, illuminance, spectral light, head motion, and visuomotor responses. The goal is to understand how multiple visual stimuli interact within each child and influence myopia onset or progression. Participation involves home use of VEET for eight days every six months over about three years. The study includes both myopic and non-myopic children, with tailored eligibility based on refractive error and binocular function.
Why it matters
Potential benefit: If successful, findings could inform personalized strategies to prevent or slow myopia by optimizing a child’s visual environment.
How similar studies have gone: Prior work has shown that environmental and behavioral visual factors influence myopia, but this study is among the first to longitudinally integrate multiple visual-diet components in individual children.

Inclusion Criteria: * Age: 7-12 years old (inclusive) * Astigmatism of \< 1.50D * Stereopsis equal or better 100 seconds of arc * Normal binocular functions. In addition, for the Myopic group: \- Cycloplegic autorefraction (spherical equivalent, SEQ) between -0.50D and -6.00D, who are not currently pursuing nor intending to start myopia control at the time of enrollment. For the non-myopic group: \- SEQ between plano and +2.50D. Exclusion Criteria for both groups: * History of refractive surgery or myopia control * Binocular abnormalities * Ocular and systemic pathologies * Developmental delay * Unable to wear the VEET at home for 8 days every 6 months for 3 years * Pre-term birth (\< 34 weeks of gestational age).
